Description: This course will help librarians and others involved in health information outreach to design quality programs and garner support for those programs by taking the right first step: collecting community and needs assessment information about the groups of people who will be involved. By the end of the course, participants should know how to collect data that will create a picture of their target community, including its needs, assets, resources, and potential obstacles that may affect the success of health information outreach efforts. Participants will learn how to use existing data, such as US Census data, state data, and local resources in community assessment. They also will learn the type of information they should seek through interviews and surveys. The workshop will combine lecture with interactive group exercises that allow participants to work with data and plan community assessments. The webcast version of the course will be held: Wednesday, January 14, 2008 for Hour 1; Wednesday, January 21, 2008 for Hour 2; and Wednesday, January 28, 2008 for Hour 3. Time is 10:00 am Pacific Time all 3 days.

Need for This Course: The NN/LM established the Outreach Evaluation Resource Center with a goal of increasing the use of evaluation in the network to develop community-responsive outreach projects and demonstrate to partners and stakeholders that their efforts have made a difference. This workshop is one of four that have been designed to meet the OERC's mission of providing training and consultation in evaluation of health information programs. This workshop has been designed in accordance with a trend in the field of evaluation called evaluation capacity building, which emphasizes evaluation strategies that keep program implementers and stakeholders centrally involved in the evaluation process by training them to evaluate their own programs: they learn to identify the type of data they need to make important decisions, collect data that is credible and useful to them, and learn to apply it in making important program decisions.
The instructional methods used include Lecture, Demonstration, Slides, Discussion, Case Study, and Problem-based.
Participant Materials: · PowerPoint slide handouts · Worksheets for class exercises or homework assignments . A list of resources for conducting community assessment · A copy of the OERC's "Planning and Evaluating Health Information Outreach Projects " booklets by Olney and Barnes (Seattle, Washington: National Network of Libraries of Medicine Pacific Northwest Region, 2006).
Facility Requirements: The face-to-face version of this workshop requires a room with seating arrangements that will allow participants to face forward for lecture, but re-arrange chairs and tables for small group work. Instructors need a computer/projector set-up for PowerPoint slides. A flipchart, pens and tape are also needed. A connection to the Internet would be helpful. The webcast version of this workshop requires participants to have a computer with an Internet connection plus a telephone. This version includes homework assignments to be completed before the second hour and before the third hour. Because of that additional time requirement for participants, this version of the class is for 4 MLA contact hours.
Additional Evaluation: Face-to-face version: followup questionnaires sent to participants 6 months after they take the class to see how they have used the material. Webcast: similar followup questionnaires plus onscreen quizzes during each hour of the webcast. We will also email each participant a copy of the MLA CE evaluation form and will send MLA CE certificates when we receive completed evaluation forms.

If you like hiking and getting back to nature, then this lodge, a five-minute walk deep in the rain forest, is for you. It is primarily solar powered, which means mostly sun showers, no television, and candlelight after dark. Five of the 12 cottages have hot tubs, but they're very basic (their charm comes from ornate nature-theme wall paintings and starry ceilings done by local artist Heleen Cornet). The bathroom showers, some heated by propane, have a spout coming out of the ceiling. Interspersed among the cottages are herb and vegetable gardens, whose produce is used in the Rainforest Restaurant. A swimming pool is cleaned using an environmentally sensitive process. Other amenities include a sauna and a kid's pool with waterslide. Breakfast is available for an additional charge.

The various forms of uncleanness according to the Mosaic law are enumerated in Lev. 11-15; Num. 19. The division of animals into clean and unclean was probably founded on the practice of sacrifice. It existed before the Flood (Gen. 7:2). The regulations regarding such animals are recorded in Lev. 11 and Deut. 14:1-21. The Hebrews were prohibited from using as food certain animal substances, such as (1) blood; (2) the fat covering the intestines, termed the caul; (3) the fat on the intestines, called the mesentery; (4) the fat of the kidneys; and (5) the fat tail of certain sheep (Ex. 29:13, 22; Lev. 3:4-9; 9:19; 17:10; 19:26). The chief design of these regulations seems to have been to establish a system of regimen which would distinguish the Jews from all other nations. Regarding the design and the abolition of these regulations the reader will find all the details in Lev. 20:24-26; Acts 10:9-16; 11:1-10; Heb. 9:9-14.

i love to be a freelancer but with my current expenses, it almost impossible :)
freelancer is good, time flexible but need good responsibility and understand own ability :)
Freelancing is not as such easy work, you need to have the best skills, you need to be quick, responsive and master in your field. If you are thinking to quit the job and want to start the work as freelancer then you must be aware of this side effect. No, doubt if you have good skills, extra talented then you will make more money than doing job for fixed salary.
Other benefits of freelancing are :
1) Job authority
2) you are all in all for ever thing
3) No leaves problems
4) All the money is yours, no partnership, depends
Freelancing is good business people can do work at home. It has less burden of work no team pressure. For me Its a really good business.

support regulating expression, at least some of the time. 55 Wyatt summarizes his findings aptly: "Americans do believe that they believe in free expression. But, in fact, those same Americans most often believe in regulating, limiting, or suppressing expression.' 56
It follows that there is a wide difference between what media professionals believe about the rights of the media and what the public believes. Simply put, the people believe in a right to free expression, but they hold it as a personal right. They do not perceive the media to be persons exercising a personal right to free expression; rather, they see the media as an institution, like governments and churches, that have rights mostly in relation to other institutions but, in relation to the people, have only responsibilities. Thus people consistently express a belief that the press should be generally free from government interference except in cases involving legitimate governmental responsibilities (Hke national security), but they don't agree with legal protections that the press currently enjoys from libel prosecutions by individuals, nor do they condone press interference with privacy. 57
Within these bounds, the press seems to be relatively popular compared with other institutions. In a 1988 Gallup Times-Mirror survey, the "daily newspaper you are most familiar with" and "network TV news" achieved a higher percentage of "highly favorable" ratings--22 percent and 21 percent, respectively--than any other institution, including the military (17 percent), the Supreme Court (13 percent), Congress (10 percent), lawyers (7 percent), and the CIA (4 percent). 58
These polls are as interesting for what they reveal about news professionals as for what they tell us about the public. The news media involved express great concern for the safety of a democracy in a land where the people have no confidence in the information they receive, but also pronounced is a sense of professional and institutional anxiety: the media fear that the public will condone the curtailment of the traditional prerogatives of the press. Moreover, the media fear that such curtailment will come because the public fails to accept a "social-responsibility" justification for media rights. A subtext behind the construction of the questionnaires used is a fear that the public thinks of the media in the same category as automobile manufacturers and other big businesses rather than in the category of medicine, law, and the other professions or the category of Congress, the judiciary, and other public institutions. Because freedom of the press has become in practice a right for corporate entities and not for individuals, it is important that the public view the media as corporate entities of the sort that deserve special protection, instead of simply as profit-making businesses.
The level of violence against the press currently is as low as it's ever been. Journalists and news executives consider violence to be a rather unimportant feature of their work environment. Far more significant, judging from written responses to my survey and published remarks, is the fear of legal action, especially libel suits. In addition to being violent, Americans have always been litigious.

KIT researchers developing low-pressure carbonitriding process for hardening steel with methylamine; applications in downsized engines
November 23, 2015
A team at the Karlsruhe Institute of Technology (KIT) is developing a new low-pressure process for hardening steel using methylamine. The new low-pressure carbonitriding (enriching low-alloy steels with carbon and nitrogen) process saves time and process gas. Steels hardened in this way are suited for use in components subjected to high mechanical and thermal loads in downsized, energy-efficient and low-emission engines of the future.
The KIT researchers, along with their colleagues at Bosch, presented the process in a recent paper published in HTM - Journal of Heat Treatment and Materials.
Tohoku U team produces rare-earth-free high quality Fe-Ni magnet with simple industrial technology
November 22, 2015
Researchers from Tohoku University in Japan have succeeded in producing a completely rare-earth free high-quality Fe-Ni magnet. The team, led by Professor Akihiro Makino as principal investigator is supported by a MEXT (Ministry of Education, Culture, Sports, Science and Technology, Japan) project entitled, "Ultra-low Core Loss Magnetic Material Technology Area," under the framework of the "Tohoku Innovative Materials Technology Initiatives for Reconstruction."
Currently high quality magnets, which are used in various applications such as automobiles, household appliances, medical equipment etc. are made up of rare earth elements such as Sm (samarium), Nd (neodymium) and Dy (dysprosium). Importing rare earth elements is costly, and has become "too political," the researchers said, making it increasingly difficult for Japan to maintain industrial superiority and competitiveness in the production of energy-saving technologies for next generation of electrical machines/devices.
EuroCarBody Award 2015 goes to the Carbon Core body of the new BMW 7 Series
November 12, 2015
The Carbon Core body structure of the new BMW 7 Series has been awarded the EuroCarBody Award 2015 at the 17th Global Car Body Benchmarking Conference. The body of the new BMW luxury sedans was given a rating of 41.87 out of 50 possible points—the best score ever to be obtained in this competition. The EuroCarBody Award has been announced at the annual conference of experts every year since 2002 and is regarded as a leading award for innovations in car body construction.
The Carbon Core used for the body structure is the central element of the BMW EfficientLightweight Technology that was applied particularly consistently in the development of the sixth generation of the BMW 7 Series. For the first time in a volume-production automobile, a composite of CFRP, aluminium and super high-strength steels was created which increases rigidity and stiffness in the passenger cell while at the same time significantly reducing the vehicle weight.
ORNL, industry partners using high-performance computing to develop new high-temperature aluminum alloys for engines
November 11, 2015
The Department of Energy's Oak Ridge National Laboratory, FCA US LLC, and Nemak, a specialist in the production of high complex aluminum components for the automotive industry such as cylinder heads and engine blocks, are partnering to create lightweight powertrain materials that will help the auto industry meet the mandated target of 54.5 mpg (4.3 l/100 km) by 2025. Using high-performance computing, ORNL researchers are modeling the atomic structure of new alloys to select the best candidates for physical experimentation.
The ORNL-led project is part of a new initiative from DOE's Vehicle Technologies Office to develop such new high-performance alloys. Ford, General Motors and FCA US are collaborating with national laboratories, universities and the casting industry to develop an affordable, 300 ˚C-capable high-strength cast aluminum alloy.
Vaporized Foil Actuator Welding technique from OSU uses 80% less energy and delivers bonds 50% stronger; joining dissimilar materials
October 30, 2015
Engineers at The Ohio State University have developed a new welding technique—Vaporized Foil Actuator Welding (VFAW)—that consumes 80% less energy than a common welding technique, yet creates bonds that are 50% stronger. The new technique could have a significant impact on the auto industry, which is poised to offer new cars which combine traditional heavy steel parts with lighter, alternative metals to reduce vehicle weight.
Glenn Daehn, professor of materials science and engineering at Ohio State, who helped develop the new technique, explained the new process in a keynote address at the recent Materials Science & Technology 2015 meeting. The Materials Science & Engineering annual meeting is organized by the American Ceramic Society, the Association for Iron & Steel Technology, ASM International, and the Minerals, Metals & Materials Society.
Acura provides more technical detail on NSX sports hybrid AWD powertrain, body
October 28, 2015
Acura unveiled the production model of the next-generation NSX at the North American International Auto Show (NAIAS) this past January (earlier post), and now has provided more technical detail on the high-performance hybrid sports car and its new Sport Hybrid-AWD power unit.
At the core of this new hybrid power unit is a bespoke, mid-mounted twin-turbocharged, 75-degree 3.5-liter DOHC V6 engine with dry sump lubrication, mated to an all-new 9-speed dual clutch transmission (9DCT) and Direct-Drive Motor. This is augmented by the front Twin Motor Unit (TMU) driving the front wheels. The NSX Sport Hybrid power unit offers exceptional horsepower and torque with a broad powerband for tremendous throttle response and acceleration. Total system peak output is estimated at 573 horsepower—500 horsepower from the gasoline engine and 73 horsepower from the front TMU.
New flexible MOF for enhanced adsorbed natural gas storage on vehicles
October 27, 2015
An international team of researchers led by a group at the University of California, Berkeley has developed a flexible metal-organic framework (MOF) material for enhanced adsorption and desorption of natural gas (CH4). The material, described in a paper in the journal Nature, could bolster the development of on-board adsorbed natural gas (ANG) systems that don't require the high pressures or cold temperatures of today's compressed or liquefied natural gas vehicles.
The "flexibility" is the result of a reversible phase transition. The iron and cobalt compounds Fe(bdp) and Co(bdp) (bdp2− = 1,4-benzenedipyrazolate) undergo a structural phase transition in response to specific methane (CH4) pressures, resulting in adsorption and desorption isotherms that feature a sharp step. Such behavior enables greater storage capacities than have been achieved for classical adsorbents, the team found, while also reducing the amount of heat released during adsorption and the impact of cooling during desorption.
DOE issues RFI on advanced thermal insulation for cold/cryogenic compressed gas on-board fuel storage
October 21, 2015
The US Department of Energy's (DOE) Fuel Cell Technologies Office (FCTO) has issued a request for information (RFI) (DE-FOA-0001420) on advanced thermal insulation for sub-ambient temperature alternative fuel onboard storage systems. Alternative fuels could include hydrogen or natural gas stored onboard the vehicle at sub-ambient temperatures as a compressed gas, liquefied gas or adsorbed onto a porous material.
DOE is requesting information on how to maintain vacuum stability of systems; use of advanced composites within the systems; and accelerated test methods to determine performance and applicability of materials and systems for long-term cold and cryogenic based alternative fuel storage systems for onboard vehicle applications.
Berkeley Lab findings should bolster future application of black phosphorous nanoribbons in electronic, optoelectronic and thermoelectric devices
October 19, 2015
A team led by a group of researchers at the US Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) has experimentally confirmed strong in-plane anisotropy—i.e., directional dependence—in thermal conductivity, up to a factor of two, along the zigzag and armchair directions of single-crystal black phosphorous nanoribbons.
This new experimental revelation about black phosphorus nanoribbons should facilitate the future application of this highly promising material to electronic, optoelectronic and thermoelectric devices.
Argonne study finds lightweight material substitution increases vehicle-cycle GHGs, but results in total life-cycle benefit
October 12, 2015
A team at Argonne National Laboratory has taken a closer look at vehicle-cycle (all processes related to vehicle manufacturing) and vehicle total life-cycle (vehicle-cycle plus fuel cycle—i.e., the use phase) impacts of substituting lightweight materials into vehicles.
In a study published in the ACS journal Environmental Science & Technology, they reported that while material substitution can reduce vehicle weight, it often increases vehicle-cycle greenhouse gas emissions GHGs—for example, replacing steel with wrought aluminum, carbon fiber reinforced plastic (CRFP), or magnesium increases the vehicle-cycle GHGs. However, lifetime fuel economy benefits often outweigh the vehicle-cycle, resulting in a net total life-cycle GHG benefit, they found. This is the case for steel replaced by wrought aluminum in all assumed cases, and for CFRP and magnesium except for high substitution ratio and low fuel reduction value.
GM planning to "own" the customer relationship beyond the vehicle; autonomous Volts, car sharing and fuel cells
October 01, 2015

GM also said it plans to strengthen its core business through global growth initiatives and an aggressive product launch cadence, while continuing to focus on driving cost efficiencies. As a result, the company expects to increase its earnings per share and generate significant shareholder value. The company shared its plans with investors during a conference at its Milford Proving Ground.
WPI team develops process to recover rare earth elements from discarded motors of electric and hybrid vehicles
In an effort to help develop a sustainable domestic supply of rare earth elements and lessen US dependence on China for materials that are vital to the production of electronics, wind turbines, and many other technologies, two researchers at Worcester Polytechnic Institute (WPI) have developed a method of extracting rare earths from the drive units and motors of discarded electric and hybrid cars.
The process offers a recovery rate of more than 80%. While heat treatment is required for processing, all other steps can be performed at room temperature, thus resulting in a process designed for energy efficiency. Overall, the established process applies green chemistry principles for designing a hydrometallurgical process.
Alcoa splitting into two companies; expecting 2.4x increase in automotive revenues to $1.8B in 2018
September 28, 2015
The Board of Directors of Alcoa has unanimously approved a plan to split the lightweight metals leader into two independent, publicly-traded companies. The globally competitive Upstream Company will comprise five business units that today make up Global Primary Products: Bauxite, Alumina, Aluminum, Casting and Energy.

New Mahle piston ring coating for high-output GTDI engines; chromium nitride using high-velocity oxygen fuel process
September 16, 2015
Mahle has developed a new thermal spray coating for modern high-output direct-injection turbocharged gasoline engines (GTDI). Under development since 2011 at Mahle's thermal spray development labs in Michigan, the new process initially was designed for high-output GTDI engines currently in production by two US domestic automakers. The market for high-output turbocharged engines is expected to achieve a market share of 30% or more by 2020.
The new top ring coating, also referred to as MSC312, uses chromium nitride applied through a high-velocity oxygen fuel (HVOF) thermal spray process. MSC312 improves upon the scuff-and-wear capabilities of Mahle's MSC385 chrome carbide HVOF coating because of the chromium nitride composition.
SLAC's new electron camera visualizes ripples in 2-D material; support for future solar cells, electronics and catalysts
September 10, 2015
New research led by scientists from the Department of Energy's SLAC National Accelerator Laboratory and Stanford University reveals how individual atoms move in trillionths of a second to form wrinkles on a three-atom-thick material. Visualized by a new "electron camera," one of the world's speediest, this unprecedented level of detail could guide researchers in the development of efficient solar cells, fast and flexible electronics and high-performance chemical catalysts.
As described in a paper published in the ACS journal in Nano Letters, the study was made possible with SLAC's instrument for ultrafast electron diffraction (UED), which uses energetic electrons to take snapshots of atoms and molecules on timescales as fast as 100 quadrillionths of a second.
Federal-Mogul Powertrain develops new high strength aluminium alloy material for automotive diesel pistons
September 03, 2015
Federal-Mogul Powertrain has developed a new premium diesel piston aluminium alloy: DuraForm-G91. In benchmarking tests, the new alloy—which will be on display at the IAA show later this month—provides between three and five times the component life of established as-cast materials in modern, highly loaded, diesel engines. The increased strength of the new material also supports higher mechanical loads, allowing engines to operate at higher specific power and more efficiently.
The enhanced alloy properties facilitate piston designs with a lower compression height and reduced mass. The resulting benefits of less reciprocating mass and smaller, lighter cylinder blocks contribute to vehicle CO2 emissions reduction.
GWU team develops low-cost, high-yield one-pot synthesis of carbon nanofibers from atmospheric CO2
August 21, 2015
A team led by Dr. Stuart Licht at The George Washington University in Washington, DC has developed a low-cost, high-yield and scalable process for the electrolytic conversion of atmospheric CO2 dissolved in molten carbonates into carbon nanofibers (CNFs.) The conversion of CO2 → CCNF + O2 can be driven by efficient solar, as well as conventional, energy at inexpensive steel or nickel electrodes.
The structure is tuned by controlling the electrolysis conditions, such as the addition of trace transition metals to act as CNF nucleation sites; the addition of zinc as an initiator; and the control of current density. An open access paper on their work is published in the ACS journal Nano Letters; the work was also presented at ACS' 250th National Meeting & Exposition this week in Boston.

Ford working with OSU on sustainable alternative rubber sources for non-tire vehicle applications
August 06, 2015
While there are a number of efforts underway exploring the use of sustainable, natural rubber alternatives for use in tires (earlier post, earlier post, earlier post), cars use a great deal of rubber for non-tire applications as well; the Ford Fiesta, for example, contains about 3 kg of the material, excluding the tires.
Ford Motor Company is thus investigating alternative sustainable sources of rubber for automotive use in these non-tire applications. The company is working closely with The Ohio State University's Ohio Agricultural Research and Development Center's (OARDC's) Program of Excellence in Natural Rubber Alternatives (PENRA) on researching the use of latex from guayule and Russian dandelion root in applications such as the car's interior (cup holders), floormats, suspension bushings, engine mounts and so on, said Janice Tardiff, Elastomer Technical Expert at Ford.
Purdue team discovery could reduce energy required to machine annealed metals by >50%
July 28, 2015
Researchers at Purdue University have discovered a previously unknown type of metal deformation—sinuous flow—and a potentially simple method to suppress it. The results, reported in a paper in the Proceedings of the National Academy of Sciences (PNAS), could lead to more efficient machining and other manufacturing advances by significantly reducing the force and energy required to process metals by more than 50%.
Annealing is a heat-treatment process used to soften metals for machining. Counterintuitively, however, annealed metals are surprisingly difficult to cut, the Purdue team noted, involving high forces and an unusually thick "chip." The conventional explanation for this anomaly has used a model of smooth plastic flow with uniform shear to describe material removal by chip formation. In their study, the Purdue team showed that the phenomenon is actually the result of a fundamentally different collective deformation mode: sinuous flow. Using in situ imaging, they found that chip formation occurs via large-amplitude folding, triggered by surface undulations of a characteristic size.
GM using Continental Structural Plastics' TCA Ultra Lite in Corvette for 20 lb weight savings
July 22, 2015
Continental Structural Plastics (CSP), a global provider of lightweight composite solutions, announced that its Tough Class A (TCA) Ultra Lite material, introduced in September 2014, is now in production on the 2016 Chevrolet Corvette. The use of TCA Ultra Lite, a Class A body panel material, results in a 20 lb (9 kg) weight savings on the Stingray Coupe model. This is the first production use of CSP's Ultra Lite advanced composite.
Ultra Lite technology uses treated glass bubbles to replace some of the CaCO3 (calcium carbonate) filler, allowing the resin to adhere to the matrix and increase the interfacial strength between the bubble and the resin. This is a patented treatment technology that results in a more robust resin mix that makes molded parts more resistant to handling damage, and prevents the micro-cracks that cause paint pops, pits and blistering. The treated bubbles also help with paint adhesion and bonding characteristics.
NIST calculates H2 pipeline can cost up to 68% more than nat gas pipeline; proposes code change to reduce cost
July 20, 2015
Pipelines to carry hydrogen cost more than other gas pipelines because of the measures required to combat the damage hydrogen does to steel's mechanical properties (e.g., hydrogen embrittlement, HE) over time. Researchers at the National Institute of Standards and Technology (NIST) have now calculated that hydrogen-specific steel pipelines can cost as much as 68% more than natural gas pipelines, depending on pipe diameter and operating pressure.[1] By contrast, a widely used cost model[2] suggests a cost penalty of only about 10%.
However, according to the new NIST study, hydrogen transport costs could be reduced for most pipeline sizes and pressures by modifying industry codes[3] to allow the use of a higher-strength grade of steel alloy without requiring thicker pipe walls.
China Zhongwang and Brilliance Bus partner to develop all-aluminum new energy public buses
China Zhongwang Holdings Limited, the second largest industrial aluminum extrusion product developer and manufacturer in the world and the biggest one in Asia, has successfully designed, manufactured and developed all-aluminum new energy electric buses for Brilliance Bus (Dalian) Company Limited. This co-operation marks China Zhongwang's inauguration as the first and only aluminum processing enterprise in China to have the capability of undertaking both the design and manufacturing of all-aluminum new energy public buses.
The frame and body of this new public bus model use aluminum alloy as the key material. Its weight is reduced by 40% compared to its steel counterparts. Aluminium-bodied vehicles are more durable, corrosion resistant and have better vibration absorption capabilities. The lighter auto bodies increase the vehicles' driving range, thereby conserving energy and reducing operating costs.
Syntactic foam composite for lightweight yet strong materials; bending strength for automotive applications
July 17, 2015
A team of researchers reports success in pioneering tests of a layered material with a lightweight metal matrix syntactic foam core that holds significant potential for automobiles, trains, ships, and other applications requiring lightweight structural components that retain their strength even when bent or compressed. (Syntactic foams are materials with pre-formed hollow spheres as a main constituent. "Syntactic" refers to the "ordered structure" provided by the hollow spheres.)
The research team of Nikhil Gupta, a NYU School of Engineering associate professor in the Department of Mechanical and Aerospace Engineering, working with the Toledo, Ohio, company Deep Springs Technology and the US Army Research Laboratory, published their findings in Materials Science and Engineering: A.
Ford's first mass-produced carbon fiber wheels
July 12, 2015
To source the new lightweight track-capable carbon fiber wheels that are standard on the new Shelby GT350R Mustang, Ford partnered with Australia-based Carbon Revolution. Carbon Revolution first began delivering composite wheels in 2004 for Formula SAE campaigns. The company now is producing its "CR-9" wheel series in limited numbers for Porsche, BMW M3, Audi R8, Lamborghini and McLaren MP4-12C within Europe, Japan and North America. Ford, however, wanted more of a mass-production solution.
The one-piece carbon fiber wheels for the Mustang weigh nearly half that of an equivalent aluminum wheel (18 pounds versus 33 pounds), and handling and acceleration performance see serious benefits. The wheels also provide a reduction in rotational inertia of more than 40%, which positively impacts acceleration and braking performance. The wheels are so light, the springs and MagneRide dampers had to be recalibrated because the suspension can respond considerably faster to road inputs.

Stanford team develops new ultrahigh surface area 3D porous graphitic carbon material for improved energy storage
June 01, 2015
Stanford University scientists have created a new ultrahigh surface area three-dimensional porous graphitic carbon material that significantly boosts the performance of energy-storage technologies. Their results are presented in an open access paper published in the journal ACS Central Science.
The multivalent cross-linker and rigid conjugated framework help to maintain micro- and mesoporous structures, while promoting graphitization during carbonization and chemical activation. The design results in a class of hierarchically porous graphitic (HPG) carbons at temperature as low as 800 °C with record-high surface area (4,073 m2 g–1); large pore volume (2.26 cm–3), and hierarchical pore architecture. The maximum surface area achieved with conventional activated carbon is about 3,000 m2 g–1
Researchers develop high-speed friction stir welding technique for aluminum joining at high volume production speeds
May 24, 2015
In partnership with General Motors, Alcoa and TWB Company LLC, researchers from the Department of Energy's Pacific Northwest National Laboratory have developed a high-speed friction stir welding (FSW) process (earlier post) to join aluminum sheets of varying thicknesses—a key to producing auto parts that are light yet retain strength where it's most needed—at speeds required for high volume production. The PNNL-developed process is ten times faster than current FSW techniques, representing production speeds that, for the first time, meet high-volume assembly requirements. The advancement is reported in an open-access paper in JOM, the member journal of The Minerals, Metals & Materials Society.
To create door frames, hoods and other auto parts, sheets of metal are welded together end-to-end into a "tailor-welded blank" (TWB) which is then cut into appropriate sizes before being stamped into the final shape. This process allows a high degree of customization. For example, a thicker gauge of metal can be used on one side of a car part, where extra strength is needed, joined via a weld to a thinner gauge on the side where it's not.

Sandia researchers demonstrate thermoelectric behavior in a MOF
May 20, 2015
Sandia National Laboratories researchers, with colleagues at the University of Virginia, have made the first measurements of thermoelectric behavior by a nanoporous metal-organic framework (MOF), a development that could lead to an entirely new class of materials for such applications as cooling computer chips and cameras and energy harvesting. "These results introduce MOFs as a new class of thermoelectric materials that can be tailored and optimized," said Sandia physicist François Léonard.
This work, published in a paper in the journal Advanced Materials, builds on previous research in which the Sandia team realized electrical conductivity in MOFs by infiltrating the pores with a molecule known as tetracyanoquinodimethan (TCNQ), as described in a 2013 paper in Science (Talin et al. 2013).

Argonne supercomputer helped Rice/Minnesota team identify materials to improve fuel production
April 29, 2015
Scientists at Rice University and the University of Minnesota recently identified, through a large-scale, multi-step computational screening process, promising zeolite structures for two fuel applications: purification of ethanol from fermentation broths and the hydroisomerization of alkanes with 18–30 carbon atoms encountered in petroleum refining. (Earlier post.)
To date, more than 200 types of zeolites have been synthesized and more than 330,000 potential zeolite structures have been predicted based on previous computer simulations. With such a large pool of candidate materials, using traditional laboratory methods to identify the optimal zeolite for a particular job presents a time- and labor-intensive process that could take decades. The researchers used Mira, the Argonne Leadership Computing Facility's (ALCF) 10-petaflops IBM Blue Gene/Q supercomputer, to run their large-scale, multi-step computational screening process.

Ames Lab team replaces Dysprosium in permanent magnets with Cerium for lower-cost, high performance solution
April 24, 2015
Researchers led by a team at the US Department of Energy's Ames Laboratory have created a new lower-cost magnetic alloy that is an alternative to conventional NdFeB-based permanent magnets. The new alloy—a potential replacement for high-performance permanent magnets found in EV motors and wind turbines—replaces dysprosium (Dy), one of the scarcest and costliest rare earth elements.
The new alloy of neodymium, iron and boron co-doped with cerium and cobalt is a less expensive material with properties that are competitive with traditional sintered magnets containing dysprosium. As reported in a paper in the journal Advanced Materials, the Ce, Co co-doped alloys have excellent high-temperature magnetic properties with an intrinsic coercivity being the highest known for T ≥ 453 K (180 ˚C).

HRL developing a new material for hypersonic vehicles; proof-of-concept for DARPA MDP program
HRL Laboratories, LLC (formerly Hughes Research Labs) will be developing new materials for hypersonic vehicles under the Materials Development for Platforms (MDP) program through the Defense Advanced Research Projects Agency (DARPA-BAA-14-52). These new materials aim to reduce the weight and cost of vehicle aeroshells while withstanding the extreme environment encountered during hypersonic flight.
Currently, the applied material development sequence takes 10+ years. This is out of step with vehicle programs with much shorter design cycles, limiting new aerospace platforms from using new materials until they are proven. The goal of DARPA's MDP program is to connect designers and material developers together more effectively and to compress this applied material development process by at least 75% to 2.5 years using a hypersonic vehicle's aerodynamic outer shell (boost-glide hot structure aeroshell) as the initial test case.

Cadillac CT6 mixed-material body structure saves 90 kg over predominantly steel construction
March 15, 2015
Cadillac will use an advanced mixed-material approach for the lightweight body structure of the upcoming CT6 range-topping full-size sedan, which will debut 31 March at the New York International Auto Show. The structure is aluminum-intensive, but the new Cadillac also includes 13 different materials customized for each area of the car to advance driving dynamics, fuel economy and cabin quietness; the mixed material approach saved 90 kg (198 pounds) compared to a predominately steel construction.
Sixty-four percent of the CT6 body structure is aluminum, including all exterior body panels. Thirteen complex high-pressure die cast components make up the lower structure of the CT6 body, along with aluminum sheets and extrusions. The vehicle underbody uses steel close-out panels on the lower structure to create a bank vault-quiet cabin without the added weight of extensive sound-deadening material, often used to compensate for aluminum panels in the occupant compartment.

Penn and ExxonMobil researchers uncover mechanisms behind performance of major antiwear additive in lubricants
March 13, 2015
One of the main modern antiwear lubricant additives is zinc dialkyldithiophosphate (ZDDP)—widely used in automotive lubricants—which forms crucial antiwear tribofilms at sliding interfaces. However, despite its importance in prolonging machinery life and reducing energy use, the mechanisms governing its tribofilm growth are not well-understood. This limits the development of replacements with better performance and catalytic converter compatibility.
Now, in a study published in the journal Science, researchers from the University of Pennsylvania and ExxonMobil, have uncovered the mechanisms governing the growth of ZDDP antiwear tribofilms at sliding interfaces. The study provides a way forward for scientifically testing new anti-wear additives. Being able to pinpoint the level of stress at which they begin to break down and form tribofilms allows researchers to compare various properties in a more rigorous fashion.

UC Berkeley chemists have developed a new material that can efficiently capture CO2 and then release it at lower temperatures than current carbon-capture materials, potentially cutting by half or more the energy currently consumed in the process.
The material, a metal-organic framework (MOF) modified with nitrogen compounds called diamines, can be tuned to remove carbon dioxide from the room-temperature air of a submarine, for example, or the 100-degree (Fahrenheit) flue gases from a power plant. A paper elucidating the mechanism of what the researchers are calling "phase-change" adsorbents is published in the journal Nature.

Sub-micrometer carbon spheres as oil additives reduce engine friction up to 25%
March 06, 2015
Researchers at Purdue University have shown that adding ultra-smooth submicrometer carbon spheres to motor oil can reduce friction and wear typically seen in engines by up to 25%. The researchers also have shown how to potentially mass-produce the spheres, making them hundreds of times faster than previously possible using ultrasound to speed chemical reactions in manufacturing.
In a paper in the ACS journal Advanced Materials & Interfaces, they reported that the new lubricant composition—3% carbon spheres suspended in a reference SAE 5W30 engine oil—exhibited a substantial reduction in friction and wear (10 to 25%) compared to the neat oil, without change in the viscosity. Friction reduction was dependent on the sliding speed and applied load, and maximum reduction was achieved at the highest sliding speed in the boundary lubrication regime.

POSTECH researchers develop new high-strength, lightweight steel
February 27, 2015
Researchers at Pohang University of Science and Technology (POSTECH) in South Korea have developed a new type of steel with improved tensile strength and lightness. In their approach, they effectively utilized a brittle intermetallic compound (B2) that metallurgists usually try to suppress by modifying B2 morphology and dispersion in the steel matrix.
The specific tensile strength and ductility of the developed steels improve on those of the lightest and strongest metallic materials known, titanium alloys, the researchers said. The results, reported in a paper in the journal Nature, demonstrate how intermetallic compounds can be harnessed in the alloy design of lightweight steels.

Lux: carbon fiber to go mainstream in automobiles by 2025
February 22, 2015
Driven by a faster-than-expected pace of technology development, carbon-fiber reinforced plastics (CFRPs) will be poised to gain widespread adoption for automotive lightweighting by 2025, according to a new report from Lux Research, "Scaling Up Carbon Fiber: Roadmap to Automotive Adoption."
Advances already underway in fiber, resin and composite part production will lead to a $6 billion market for automotive CFRPs in 2020, more than double Lux's earlier projection. (Earlier post.) Even this figure is dwarfed by the full potential for CFRPs in automotive if they can become affordable enough for use in mainstream vehicles, Lux posits.

Rice, Minnesota scientists use predictive modeling to identify optimized zeolites to aid ethanol, petroleum production
January 23, 2015
Scientists at Rice University and the University of Minnesota have identified, through a large-scale, multi-step computational screening process, promising zeolite structures for two energy-related applications: the purification of ethanol from fermentation broths and the hydroisomerization of alkanes with 18–30 carbon atoms encountered in petroleum refining.
The results, presented in a paper published in Nature Communications, demonstrate that predictive modeling of synthetic zeolites—a technique pioneered by Rice bioengineer Michael Deem—and data-driven science can be applied to solve some of the most challenging problems facing industries that require efficient ways to separate or catalyze materials.

UQM Technologies granted patent on permanent magnet electric motor design using non-rare earth magnets
January 20, 2015
UQM Technologies Inc. has been granted a US patent (8,928,198, "Brushless PM machine construction enabling low coercivity magnets") for an electric and hybrid electric vehicle motor design using non-rare earth magnets. The patent covers the unique magnet geometry and the method of manufacturing the motor.
The majority of electric and hybrid electric vehicles produced today use permanent magnet (PM) motors with rare-earth magnet materials because of the high coercivity of the rare earth materials. Coercivity is a measure of the reverse field needed to drive magnetization to zero after being saturated—i.e., it is a measure of the resistance to demagnetization. The new UQM design enables the use of low coercivity magnets, such as Aluminum Nickel Cobalt (AlNiCo) or Iron Cobalt Tungsten (FeCoW), in PM machines.

Researchers suggest hybrid graphene oxide/cellulose microfibers could supersede carbon fibers
January 16, 2015
Researchers from Nanjing Forestry University and the University of Maryland have designed high-performance microfibers by hybridizing two-dimensional (2D) graphene oxide (GO) nanosheets and one-dimensional (1D) nanofibrillated cellulose (NFC) fibers. The resulting well-aligned, strong microfibers have the potential to supersede carbon fibers due to their low cost, the team suggests in an open access paper published in the journal NPG Asia Materials.
The hybrid microfibers are much stronger than microfibers composed of 1D NFC or 2D GO alone. In their paper, they reported that experimental results and molecular dynamics simulations reveal the synergistic effect between GO and NFC: the bonding between neighboring GO nanosheets is enhanced by NFC because the introduction of NFC provides the extra bonding options available between the nanosheets.

January 14, 2015
|The new Ford GT on display in the Ford stand at NAIAS. Click to enlarge.
In December, Ford President and CEO Mark Fields said Ford would focus on five key areas of innovation, one of them being performance. He said that more than 12 new performance vehicles would be introduced through 2020. (Earlier post.) At the North American International Auto Show (NAIAS) in Detroit this week, Ford delivered first proof of that focus with the reveal of the new Ford GT carbon-fiber supercar, as well as the new F-150 Raptor based on the new aluminum F-150 and the Shelby GT350R Mustang.
The stunning Ford GT—which received the EyesOn Design Award at NAIAS for best production vehicle—serves as a technology showcase for top EcoBoost engine performance, aerodynamics and lightweight carbon fiber construction. Beginning production late next year, the GT will the road in select global markets in honor of the 50th anniversary of Ford GT race cars placing 1-2-3 at the 1966 24 Hours of Le Mans. However, unlike today's hybrid drive Le Mans racers, or the new Acura NSX hybrid supercar, also revealed at NAIAS (earlier post), the GT—nor any of the other Ford performance vehicles unveiled at NAIAS—makes no use of electric drive technology.

ASG life-cycle study finds aluminum Ford F-150 "Best Full-size Truck of 2015" from environmental and economic perspective
According to the latest annual life-cycle study from the Automotive Science Group (ASG), the all-new lightweight aluminum 2015 Ford F-150 leads the full-size light-duty truck competition in all environmental and economic performance areas; accordingly, ASG selected the F-150 as its Best Full-size Truck of 2015. According to ASG and the principles of ecological economics, environmental and economic considerations are equally important in determining a vehicle's overall value. ASG's proprietary vehicle rating platform—the Automotive Performance Index—analyzes both performance areas for a comprehensive vehicle assessment. ASG's 2015 Study assessed 225 light-duty truck models.
Although the gasoline-fueled F-150 with 2.7L EcoBoost delivers 22 mpg (10.68 l/100 km) combined—1 mpg shy of RAM's EcoDiesel—the F-150's life-cycle environmental and economic performance "leaves RAM and others in the dust," according to ASG. According to ASG, the 2015 F-150 holds the smallest life-cycle carbon footprint and lowest cost of ownership of any full-size truck in the North American market today. Ford has produced a lightweight aluminum-intensive truck that costs less and performs better than its conventional truck counterparts over the vehicle's life-cycle, says Colby Self, managing director of ASG.

December 28, 2014
|This sheet of graphene contains an array of crown ethers that can strongly bind select guest ions or molecules. Image credit: ORNL. Click to enlarge.
A team led by the Department of Energy's Oak Ridge National Laboratory has discovered a way to increase significantly the selectivity and binding strength of crown ethers by embedding them within a rigid framework of graphene. The results, published in Nature Communications, may enable broader use of crown ethers in diverse applications. Their strong, specific electrostatic binding may advance sensors, chemical separations, nuclear-waste cleanup, extraction of metals from ores, purification and recycling of rare-earth elements, water purification, biotechnology, energy production in durable lithium-ion batteries, catalysis, medicine and data storage.
Ethers are simple organic molecules in which an oxygen atom bridges two carbon atoms. When linked together in crown-shaped large molecular rings, they have the ability selectively to incorporate various atoms or molecules within the cavity formed by the ring. The size and shape of the cavity formed within a crown ether molecule confers selectivity for complementary ions and small molecules that fit it, like a lock and key. Crown ethers come in different sizes, so they can accommodate ions of different diameters.

Rice U team uses new computational methodology to identify high capacity MOFs for on-board natural gas storage
December 18, 2014
Researchers from Rice University, Lawrence Berkeley National Laboratory and UC Berkeley have developed a computational methodology to support the experimental exploration of potential high-capacity metal organic frameworks (MOFs) for use in on-board storage of natural gas. The advantages to using MOFs as a storage medium are many and start with increased capacity over the heavy, high-pressure cylinders in current use.
In a paper in the ACS Journal of Physical Chemistry C, they report identifying 48 materials with higher predicted deliverable capacity (at 65 bar storage, 5.8 bar depletion, and 298 K) than MOF-5—the currently best available for the natural gas storage application. The best material identified by the researchers has a predicted deliverable capacity 8% higher than that of MOF-5.

New high-entropy alloy is as light as aluminum, stronger than titanium alloys
December 11, 2014
Researchers from North Carolina State University and Qatar University have developed a new high-entropy alloy that has a higher strength-to-weight ratio that they say is unmatched by any other metallic material. The researchers used mechanical alloying to combine lithium, magnesium, titanium, aluminum and scandium to make a low-density, nanocrystalline alloy (Al20Li20Mg10Sc20Ti30) with an estimated strength-to-weight ratio that is significantly higher than other nanocrystalline alloys and is comparable to ceramics. An open access paper on their work is published in the journal Materials Research Letters.
High-entropy alloys (HEAs) are a new class of multi-component alloy systems in which the design of the alloys is based not on adding to a single base element, but on choosing elements that will form solid solutions when mixed at near-equiatomic concentrations. (Earlier post.) HEAs

Consultancy looks to aggressive weight reduction in major powertrain components for CO2 savings; metal and polymer matrix composites
UK automotive engineering consultancy Drive System Design (DSD) suggests the next breakthrough in CO2 emissions reduction will come from more aggressive weight reduction in major powertrain components. Analysis by the company has identified both near-term and medium-term solutions for the manufacture of items such as transmission casings using advanced composite materials, but favors modern hybrid materials such as metal and polymer matrix composites (MMCs and PMCs) over conventional carbon composite solutions.
Continual pressure on the automotive industry to reduce carbon emissions is leading to weight reduction initiatives throughout the vehicle. Currently, several of the heaviest individual components in the powertrain, such as the main casings for the transmission, are still metal (e.g., aluminum alloys, magnesium alloys and iron) castings despite the widespread use of lighter materials elsewhere on the vehicle.
