Air Force Calls Lockheed's F-35 Jet Ready for Limited Combatby
Combat jet won't have full capability for at least three years
General says F-35 will be service's 'most dominant aircraft'
The U.S. Air Force declared its version of Lockheed Martin Corp.'s F-35 ready if needed for limited combat operations, a milestone for the $379 billion program that's the Pentagon's costliest.
The service's announcement Tuesday that the combat jet has an "initial operational capability" reflects progress after early years marked by development setbacks and rising costs. But the F-35 is still in development, with flawed software among its biggest challenges, and won't have full combat capability for at least another three years.
The Air Force announced the initial milestone at the start of a five-month period it had set aside to make the decision. Lockheed's fortunes ride on the F-35, the biggest source of revenue for the world's largest defense company. The advanced fighter accounted for 21 percent of Lockheed's $12.9 billion net sales during the second quarter, according to a regulatory filing, and its impact should grow as the jet moves to full production.
"The F-35A will be the most dominant aircraft in our inventory, because it can go where our" older aircraft "cannot and provide the capabilities our commanders need on the modern battlefield," General Herb "Hawk" Carlisle, head of the Air Combat Command, said in a statement, referring to the Air Force version of the fighter.
The 15 aircraft declared operational on Tuesday can provide basic close-air support, Carlisle told reporters at the Pentagon. "We know that we will continue to add capability to this airplane just like we have with every airplane in the history of the Air Force," said. "Some of the software is significantly improved, but there's still things we are going to work on."
Combat Exercises
The Air Force's move comes about a year after the Marine Corps made a similar declaration for its version of the F-35, the most complex of the different models because it is designed for short takeoffs and vertical landings.
The Air Force version won't be declared to have full combat capability until it undergoes vigorous operational exercises that won't begin until August 2018 at the earliest and then will last as long as a year. That would be a year later than planned, largely because of technical issues that the Air Force now considers sufficiently resolved or on a path to being resolved. The first operational squadron of the F-35A will be at Hill Air Force Base in Utah.
The initial aircraft won't have all the electronic combat, data fusion, weapons capacity or automated maintenance and diagnostics capabilities until the most advanced version of its complex software is fielded by 2018.
The F-35 initially will carry either two 2,000-pound GPS-guided bombs or two 500-pound laser guided weapons, plus two air-to-air missiles.
Lockheed has said it's on track to deliver 53 F-35s this year, bringing cumulative deliveries to about 180. The company has said it expects to more than double output to 120 aircraft by 2019.
For a Bloomberg Intelligence analysis of Lockheed, click here.
The Air Force doesn't have a recent track record of deploying combat planes in missions soon after a combat capability is declared. The B-1B bomber, for example, first flew missions in December 1998 against an Iraqi Republican Guard target, about 12 years after it was declared ready. Lockheed's F-22 stealth fighter flew its first combat missions in September 2014 against Islamic State targets, about nine years after it was deemed combat-ready.
Still, Carlisle said that he'd expect to see the F-35 deployed much quicker than the F-22, either on a combat mission or for training exercises, because other countries planning to buy it would like to see it in action.
"Many of our partners and allies are really interested in interoperability" during combined air operations with their non-F-35 aircraft, he said. Deploying the F-35 to the Pacific or Europe "will give our allies and partners confidence in the airplane," he said.
'Known Deficiencies'
Michael Gilmore, head of the Pentagon's testing office, warned in January that more than 500 of the fighter jets may be built before combat testing is complete, requiring costly retrofitting of the earlier F-35s.
In June, he said that today's F-35s will "have limited combat capability."
"If used in combat, these aircraft have been fielded with known deficiencies and will require support" from other aircraft or ground operators "to avoid threats, assist in target acquisition, and control weapon employment for the limited" weapons available, he said.
The F-35 is a flying computer, with more than 8 million lines of software code. At a projected cost of $379 billion for a fleet of 2,443 aircraft, it's also the costliest U.S. weapon system and one of the most closely scrutinized. The Air Force plans to buy 1,763 of them.
While Carlisle told reporters that he wouldn't hesitate to deploy the F-35 for combat if it's requested by one of the U.S.'s regional commanders, he said there are no current plans to do so.

Day 1 :
Keynote Forum
Ian S. Butler
McGill University ,Canada
Keynote: Selected applications of molecular spectroscopy in cultural heritage studies
Professor Butler has been at McGill University since 1966. He has served as Department Chair and Associate Vice-Principal (Research). He is an Honorary Member of the Spectroscopy Society of Canada, a Fellow of both the Chemical Institute of Canada and the Royal Society of Chemistry. He has supervised about 200 researchers, resulting in the co-authorship of about 540 publications. His honours include thje Gerhard Herzberg Award for Excellence in Spectroscopy and the David Thomson Award for Excellence in Graduate Teaching and Supervision. His current research focuses on structural changes induced by high pressures and variable temperatures, biomass conversion, mechanochemistry and art forensics.
Throughout the world, considerable effort is being expended in identifying and preserving objects of national cultural heritage interest. Art forensics is particularly important in repairing damaged paintings and frescoes through the identification of the pigments that artists have used over the centuries. Such pigment analyses are also crucial in identifying forgeries. Most large art museums, e.g., National Gallery in London, Getty Museum in California and Metropolitan Museum of Art in New York City, now have laboratories attached to them, which are equipped with an array of modern molecular spectroscopic instrumentation, e.g., infrared, Raman, single-crystal and powder X-ray diffraction and mass spectrometers. In our laboratory, we have focussed our research work on the applications of infrared and Raman spectroscopy in art forensics. In particular, we have used photoacoustic infrared spectroscopy in establishing a data base of molecular spectroscopic information for a wide range of solid inorganic and organic pigments. In this lecture, we will give some selected examples of molecular spectroscopy in cultural heritage studies and also describe the technique of photoacoustic infrared spectroscopy and its application in art forensics.
Keynote Forum
Véronique Jubera
ICMCB-CNRS-University of Bordeaux ,France
Keynote: How to highlight the history of a material through the registration of luminescence properties
42 years-old, University of Bordeaux associate professor-HDR, over 70 publications in international journals. She is a specialist of luminescence of inorganic doped compounds. V. Jubera has been working as an associate professor at the ICMCB-CNRS, University of Bordeaux for 14 years. Her research topic deals with the structure-luminescence properties of crystallized materials. The luminescence spectroscopy is performed to evaluate the potentiality of phosphors for displays, lighting, sensing or lasers materials. She has been developing in the Institute, topics on the synthesis and characterization of massive (single crystals, transparent ceramics) innovative compounds as well as nano-powders. Her activities is fully included and supported by the competitiveness cluster "Routes des Lasers" and the cluster Laphia (IDEX Univ. de Bordeaux).
Considerable efforts have been carried out to develop new tools and research efforts in the domain of functionalized materials (information, lighting, communication, energy etc). As an illustration, to correlate the optical response of a material to another of its property is possible through the monitoring of the luminescence.
(i) Modifications of the doping element local environment is associated to crystal field strength modification. For instance, divalent manganese radiative transitions can be observed from the green to the red ranges. Synthesis control route makes possible a red to green luminescence switch of manganese doped spinel treated at high temperature in relation with the cation migration through the host lattice. In other matrices, external factors induce unit cell symmetry transition. This effect can also be observed in rare earth doped compounds as Eu3+ doped sesquioxyde .
(ii) Irradiation energy is also an efficiency factor which can initiate redox processus. The oxidation of europium +II to europium +III state results in a shift from blue to red emission. UV irradiation of cerium doped Indium elpasolite matrix leads to the decrease of the doping element emission in favor of a bright orange emission. The corresponding redox process is reversible under adequate irradiation or heat treatment temperature. Such local modification can easily be detected over the visible range.
(iii) Emission of ZnO are strongly related to synthetic routes. Low operating temperature can result in the appearing of surface and bulk defects. Their existence impacts not only the emission wavelength but also its stability under specific atmosphere.
Finally, luminescence spectroscopy is not only a technique to register the spectral distribution of the excitation or emission radiative de-excitation, it is also an efficient tool to highlight the influence of external factors and to record the history of a materials.

Session Introduction
Hisayoshi Kobayashi
Kyoto Institute of Technology ,Japan
Title: DFT study on the partial oxidation mechanism of benzyl alcohol to benzaldehyde by O2 on TiO2 surface under visible-light irradiation
Hisayoshi Kobayashi is a Professor of Kyoto Institute of Technology. He got his Doctor's degree at Kyoto University in 1982 from Prof. Kenichi Fukui. His field is theoretical analysis of catalysis of metal and metal oxide surfaces. He got Award for Younger Researchers from the Catalysis Society of Japan in 1989, and the BCSJ Award Article from the Chemical Society of Japan in 2007. Shinya Higashimoto is Associate Professor of Osaka Institute of Technology. He received his Doctor's degree of Engineering at Osaka Prefecture University in 2000. His field is catalysis and photo-electrochemical phenomena on the metal-oxide and/or semiconductor surfaces.
The selective photocatalytic oxidation of benzyl alcohol by O2 on the TiO2 surface was theoretically studied by DFT calculations. Experimentally, it is well known that (1) benzyl alcohol is oxidized to benzaldehyde, but not further oxidized to benzoic acid, and (2) TiO2 surface itself is insensitive for the visible light, but becomes sensitive by benzyl alcohol adsorption. These phenomena were clarified by the plane wave based DFT calculations. Dehydroxylated and partially hydroxylated TiO2 with an anatase TiO2 (101) crystal face were modeled with a slab of Ti16O32 and Ti16O32(OH)H, respectively. It was found that the interaction of benzyl alcohol with the hydroxylated TiO2 surface significantly induces the formation of the alkoxide species, of which the donative orbitals hybridized with the O2p orbital in the valence band (VB) of the TiO2. The visible light response is attributed to the electronic transition from the donor levels created by the alkoxide species to the conduction band (CB). The dissociation of methylene C-H in the alkoxide was assisted by O2, and this process was confirmed to be the rate-determining step. Furthermore, the hydro-peroxide (OOH) species formed by O2 reduction can also oxidize another benzyl alcohol into benzaldehyde together with Ti-OH regeneration. It was thus clearly demonstrated that two benzaldehyde molecules were formed from two benzyl alcohols and one O2 molecule on the TiO2 photocatalys.
Patrick Grant completed his PhD at the age of 24 from Oxford University where he then undertook postdoctoral studies. He is now the Vesuvius Chair of Materials, Head of the Department of Materials at Oxford University, and leader of the Processing of Advanced Materials group that researches new processes for advanced structural and functional materials. He has published more than 200 papers journals, has 7 patents, and was elected to the Royal Academy of Engineering in 2010.
The development of electrochemical energy storage devices such as supercapacitors and Li ion batteries (LiB's) has been led by electrochemists, resulting in steady improvements in key performance metrics such as energy density, cycle life, etc. Over the same period, the production of electrochemical cells in which the positive and negative electrodes are slurry cast composites has accelerated to reach nearly 5 B pa. For a given electrochemical system, the optimisation of the electrode microstructure in these devices has been empirical, inferred from exhaustive electrochemical testing, and advanced principally by varying the average fractions of the different materials (actives, binder, conductivity enhancers, porosity, etc.) in the composite electrode. Arguably, the penetration of exciting new energy storage chemistries has been slowed and constrained by a lack of optimisation tools that account for the complexities of electrode dynamics and their degradation, and the absence of a flexible manufacturing technology for the fabrication of designed, structured electrodes with spatially varying properties.
This talk will provide an overview of recent efforts of the Oxford group to develop new processing routes that allow better micro- and meso-scale control of the electrode structure in both supercapacitors and batteries. Examples will be given of how these new approaches to electrode manufacturing can both enhance existing electrochemical systems and facilitate new systems that are otherwise difficult. Reference will be made to the cost-effectiveness and scalability of approaches, and the key insights and data that are needed from modelling and in-situ experiments to guide the future manufacture of optmised electrodes.
Rana A. Bilbeisi
American University of Beirut, Lebanon
Title: Anions tied up in a molecular knot
Rana A. Bilbeisi completed her doctoral studies in science and chemistry in 2013 at Cambridge University, UK. Her PhD work was on magnetic and host-guest chemistry properties of metallo-supramolecular capsules. After her PhD, Rana carried out her postdoctoral work on the synthesis and anion binding of metallorganic non-trivial structures at NYUAD. She started as assistant professor in the Civil & Environmental Engineering Department at the American University of Beirut since January 2016.
Knots and links are topologically fascinating entities that have been extensively explored in various scientific fields. On a molecular level, chemists developed various synthetic approaches for the preparation and characterization of knots and links. Beyond their aesthetically appealing structures, chemists explored the application of molecular knots and links as molecular machines and switches. The application of exploiting molecular recognition properties of knots and embedding them into polymeric material are areas that are still not well investigated. Topologically unique cavities of knots and links are expected to render them molecular hosts with interesting binding capabilities. Furthermore, based on the properties of naturally occurring and synthetic knotted fibers, knot-based extended networks are expected to be robust yet elastic, and are also expected to serve the material science, biomedical and chemo-sensing fields.
We reported a study where anion- binding properties of previously prepared cationic Zn((II)-based trefoil knot (TK6+) and Solomon link (SL8+) were investigated in aqueous solutions. In the solid state, the central cavity of TK6+ hosts two bromide ions through the formation of six aromatic CH…anion non-classical hydrogen bonds. In solution, TK6+ retains the property of binding monovalent anions, as evidenced though NMR titrations. Despite carrying out the study in competitive solvent, water, monovalent anions of different shapes (spherical, linear, trigonal planar and tetrahedral) and sizes (ionic radii, r, of 1.7 to 2.4 °A) were found to bind with high affinities to TK6+ in a 1:2 (TK6+ : anion) stoichiometry. The first (K1), second (K2) and global binding constants (log β2) of the anions binding were reported.
Michael Pravica
University of Nevada, USA
Title: Synthesis of novel materials via hard x-ray photochemistry
Michael Pravica is an associate professor of physics at the University of Nevada, Las Vegas (UNLV) and a member of the High Pressure Science and Engineering Center (HiPSEC) there. He obtained his B.Sc. degrees in physics and applied mathematics (with honors) from Caltech in 1988. Prof. Pravica then went on to earn his A.M. and Ph.D. degrees from Harvard University performing high pressure NMR experiments of molecular hydrogen. Prof. Pravica's research interests involve the study of organic materials (including explosives) and inorganic materials under extreme conditions of pressure, temperature, and ionizing radiation. He has also enabled a new field of science that he terms useful hard x-ray induced chemistry wherein the highly penetrating, highly ionizing, and highly focused properties of hard x-rays are harnessed to perform in situ and highly controllable chemistry.
Statement of the Problem: By harnessing the highly energetic, highly focused, and highly penetrating properties of synchrotron hard x-rays (>7keV) to drive decomposition reactions (e.g. KClO4 +hv -> KCl +2O2 [1]), we have enabled acatalytic routes of chemical synthesis of novel materials under extreme or isolated conditions with little introduction of heat. In this talk, I will showcase recent developments in by discussing three studies that showcase useful hard x-ray photochemistry [1-5]: 1. Probable synthesis of CsF2 and CsF3 at high pressure via x-ray irradiation of a mixture of CsF and KBF4 [2]. Here, the KBF4 is used as a source of molecular fluorine [3]. 2. Synthesis and ambient recovery of stable doped polymeric carbon monoxide (doped poly-CO) via irradiation of SrC2O4 pressurized to 7 GPa [4]. 3. Successful hydrogenation and oxygenation of WO3 and intercalation of oxygen into the WO3 lattice in separate experiments via irradiation of selected mixtures of WO3 with NH3BH3 and KClO4, respectively, demonstrating a novel means to dope semiconductors with the potential of creating photocells that are more resonant with sunlight [5].

Title: Protein adsorption from aqueous solution by alumina supports: A new process for enzyme recovery and reuse
Razieh Sadraei is a Ph.D. student in chemical and material science field at the university of Turin, Italy. She is working on immobilization of Protein into different inorganic supports and their applications in water treatment. She found a new pathway for recovering enzyme by adsorption and desorption processes. She has expertise in working with some instruments including Spectroscopy (FTIR-ATR with also NO derivatization mode, UV/VIS, OES), Diffractometry (XRD), zetta potential (DLS), Calorimetry and Thermo-Gravimetry (TGA), Surface Analysis (DSA) and Gas-Volumetry N2 adsorption/desorption (ASAP). She is a reviewer for International Journal of Biology (IJB) and Journal of Food Research (JFR). Her fields of interest are biotechnology and nanochemistry. Razieh has research published or is going to be published in scientific journals.
Enzymes are the biocatalysts of the living world, but their properties render them also exploitable in many applications that range from industrial catalysis to therapeutics, including synthetic and pharmaceutical chemistry, wastewater bioremediation, fabrication of high performance biosensors, among others.
The use of enzymes, however, is limited by their recovery since this aspect plays a significant role in the evaluation of the cost of the biocatalytic processes, therefore several methods have been proposed for their immobilization on stable supports. This study investigates the possibility of using different phases of nano-alumina for enzyme capture and reuse.
Alumina nanoparticles were synthesized in the γ and δ-θ phases with different shapes starting from boehmite and dawsonite thermally calcined at 500 and 1000 ˚C respectively and tested as adsorbent of commercial soybean peroxidase.
The alumina samples were characterized by thermogravimetric analysis, specific surface area, X-ray powder diffraction, scanning electron microscopy, zeta-potential and Fourier transform infrared spectroscopy.
The kinetic of recovery was evaluated in different experimental conditions (enzyme dosage, pH and temperature, presence of buffer) indicating that the supports can easily capture the enzyme which can be almost completely released for a subsequent cycle of reaction.

Title: Integrative Chemistry-based morphosyntheses of advanced porous materials dedicated towar energy conversion and storage
Rénal Backov obtained his PhD in 1997 at the University of Montpellier, France while being a post-doc fellow at the University of Florida, USA 2001. Full Professor since 2010 at the University of Bordeaux his research focuses on the rational design of advanced materials through combining physical chemistry of complex fluids and chemistry. He formalized the concept of Integrative Chemistry in 2006 and was Laureate of the French Chemical Society in 2013. With more than 140 articles and 300 contributed papers, his research encompasses the domains of energy conversion and storage, drug delivery, sensors, heterogeneous catalysis, photocatalysis, etc.
Chemical sciences are on continuous evolution offering more and more complex synthetic strategies that rely on emerging inter- and trans-disciplinary action modes. In this context, beyond the ability of constructing advanced functional materials we demonstrate how the Integrative Chemistry allows positioning chemical reactors within the geometric space. When it turns to energy dedicated advanced materials we will focused on oxide monoliths bearing hierarchical porosity. We will see first how through enzymatic engineering we can trigger biodiesel generation bearing unprecedented TON and TOF catalytic efficiency. Secondly when going from silica foams, used as hard templates, toward carbonaceous ones we will see how we can generate outstanding enzymatic biofuel cells, Li-ion and Li-S performant and stable battery electrodes. Also we will see that it is possible to trigger hydrogen storage and reversibility based on Li(BH4) confinements. Novel Bacteria-based bioreactors will be discussed.

Title: Assessment of the antifouling effect of exopolysaccharides incorporated into copper oxide-based organic paint
Graduated in Biological Sciences, Master in Biochemistry by the Institute of Chemistry (UFRJ) and Doctorate in Technology of Chemical and Biochemical Processes - Chemical Engineering by the School of Chemistry (UFRJ). He is currently an adjunct professor at the Federal University of Rio de Janeiro - Campus Macaé / Professor Aluísio Teixeira, ministering disciplines in the area of Analytical Chemistry. He has developed projects with exopolysaccharides of marine cyanobacteria for application as antifouling in anticorrosive paints. He is currently Coordinator of the Group of Bioelectroanalytics and Advanced Materials at UFRJ-Campus Macaé and develops research in the area of quantification of heavy metals in different samples using electroanalytical methods, electrode construction and modified sensors for interaction with different macromolecules, study and development of anticorrosive coatings and development of films by electropolymerization with natural marine products.
The anticorrosive and antifouling performance of copper oxide-based organic coatings incorporated with microbial exopolysaccharides (EPS) was studied using electrochemical impedance spectroscopy (EIS) and scanning electron microscopy (SEM) after immersion in water produced by oil wells and in natura seawater. EPS incorporation in the paint did not influence the coating's final anticorrosive behavior. Moreover, no bacterial adhesion occurred during the immersion period in the presence of EPS, indicating the biopolymer as a promising biocide for the antifouling paint sector.

Title: Adsorption of nisin into layered double hydroxide nanohybrids and in-vitro controlled release
I am zaineb bouaziz phd student. My research are based on double lamellar hydroxides materials used in biomedical application at the European Institute of Membranes Sciences, University Montpellier II, and France. The interest of this research area has its origin from the importance of society demand in biomedical domain.
Layered double hydroxide (LDH) nanohybrids intercalated biomolecules, including oligonecluotides, genes and peptides/proteins, have attracted particular attention since they exhibit improved safety and effectiveness as successful delivery biosystems1,2. The current study specifically investigated the adsorption of nisin peptide2 and precisely control the release of the payload. Adsorption occurred from peptide solution in contact with zinc-aluminum LDH at room temperature, looking out over the influence of the Zn2+/Al3+ ratio, the anion exchange capacity, the nature of the intercalated anion, the host matrix, and the host morphology. Higher adsorption was obtained, around 80% of the loaded nisin and successful intercalation was verified by X-ray diffraction. The in-vitro release tests of the nisin from the biohybrid formulation was held over 25 days in PBS medium (0.01 M, pH 7,4) showed that no burst release phenomenon occurred at the beginning step and a sustained-time release of nisin was obtained compared with the free nisin. Therefore, these preliminary results are encouraging for the development of bioprotectors based on nisin intercalated LDH and being implemented in the food and medical industries.

Title: Inorganic metal atom clusters as phosphorescent dyes for the design of hybrid copolymers and nanomaterials
Stéphane Cordier is specialist in crystal chemistry and cluster-based compounds (http://orcid.org/0000-0003-0707-3774). He has developed methodologies that aim at using cluster-based ceramics for the design of hybrid nanomaterials and in particular cluster-based copolymers. His research covers a continuum from fundamental research -in order to correlate physical properties to crystal and electronic structures of solid state compounds- to the integration of inorganic clusters onto functional surfaces or in optoelectronic devices. He has in charge the Group Solid State Chemistry and Materials (https://iscr.univ-rennes1.fr/csm/) from the Institut des Sciences Chimiques de Rennes.
Metal atom clusters are aggregates of metal atoms held together by metal-metal bonds. Mo6 octahedral clusters are stabilized by inner ligands (Li) in face-capping positions and apical ligands (La) in terminal positions to form [M6Li8La6]n- units. On one hand, the concept of [M6Li8La6]n- unit constitutes a useful virtual object to describe the crystal and electronic structures of cluster-based solid state compounds. On the other hand, the dissolution of solids affords discrete [M6Li8La6]n- units in solution that constitute real and handleable molecular objects with unique physico-structural properties usable as building blocks in the elaboration and structuration of molecular assemblies and nanomaterials. The delocalization of electrons on all the metal centers leads to specific physical properties as for instance luminescence and even photocatalytic properties.
Optical properties of [Mo6Li8La6]2- octahedral cluster units are characterized by a large absorption window from UV to visible and a large emission window from 550 nm to the NIR region. Thus, such clusters can be used as red phosphorescent dyes for many potential applications including nanoparticles for biolabelling, liquid crystals and luminescent nanocomposites for lighting and displays. Cs2Mo6Xi8Xa6 (X = Cl, Br and I) ternary compounds are prepared by solid state chemistry route at high temperature. Interestingly, these ceramics are soluble in many common solvent affording functional [Mo6Xi8Xa6]2- cluster units that can be further use as building blocks for the design of hybrid co-polymers. Cluster based hybrid co-polymers associate the mechanical and shaping properties of the organic matrices along with the phosphorescent properties of inorganic metallic clusters. We will present here (i) the origin of dual emission of Mo6 cluster based compounds and (ii) several examples of potential applications of nanomaterials based on the incorporation of [Mo6Xi8La6]2- cluster units in organic polymers (i.e. oxygen sensors and optical waveguides).

Title: New Cerium and Praseodymium-based oxides as redox catalysts
Dr Alain DEMOURGUES is working at ICMCB-CNRS-UPR9048 since october 1993 as Research Fellow. He became Research Director at CNRS in october 2008. He received IBM-France award in 1993 (Young scientist in Materials Science) and SFC (Société Française de Chimie) award in 2003 (Solid State Chemistry division).

He is in charge of fluorine chemistry/inorganic fluorides unit (CNRS platform 'Fluomat') and cross functional axis related to exploratory solid state chemistry.
In the last 20 years, intense efforts deal with the environmental impact decrease of the automotive exhaust gases. Highly severe regulations led to design new materials for CO, unburnt hydrocarbons oxidation and for the NOx reduction from industrial sources, especially from diesel automotive engines. Diesel Oxidation Catalysts (DOC) have then been developed to oxidize CO, hydrocarbons and NO, in order to reach the NO2/NOx ratios suitable for the downstream system of Selective Catalytic Reduction (SCR) of NOx by ammonia. Therefore, Rare-earth oxides (REO) involving mixed valence states such as Ce4+/Ce3+, Pr4+/Pr3+ and Tb4+/Tb3+ exhibit the best acid, basic and redox properties (with high oxygen availability and mobility) to fulfill the requirements of enhanced catalysts. Considering that Tb4O7 is too expensive for extended industrial applications, the objective is to finely tune the composition, structure, texture, oxygen mobility and storage of Ce/Pr/Zr based oxides to design effective and robust catalysts for DOC and SCR. Recent studies have evidenced that a fine tuning of some chemical CeO2-ZrO2-Pr6O11 compositions can stabilize Pr4+/Pr3+ rates associated with oxygen vacancies leading to high OSC, oxygen mobility, thermal stability up to 1400°C and surface areas varying between 80 and 40 m2/g at 700°C. Moreover, preliminary catalytic results for DOC application revealed outstanding properties without any PGM (Platinum Group Metal). Neutron and X-Ray diffraction analysis during the redox cycle reveal the occurrence of oxygen vacancies ordering depending on the Pr4+/Pr3+ and Ce4+/Ce3+ atomic ratios determined by magnetic measurements and XANES analysis.

Ames Laboratory of US DOE, USA
Title: Mechanochemical synthesis: Novel materials for magnetic cooling applications
Dr. Viktor Balema's expertise includes new materials development in academic and industrial environment. The main focus of his research during the last decade has been on the energy conversion and storage materials, and non-conventional materials preparation techniques, including solvent-free mechanochemistry. For a decade, between 2006 and 2016, Dr. Balema was directing Hard Materials Market Segment and Materials Science R&D at Sigma-Aldrich Co. In August of 2016, he joined the Ames Laboratory - led research consortium CaloriCoolTM where he directs the materials development group. Dr. Balema has served as expert- reviewer for the US Department of Energy, NSF, U.S. Civilian Research and Development Foundation (CRDF), ACS Petroleum Research Fund and a variety of peer reviewed scientific journals. He has also acted as section chair at annual MRS meetings and other conferences.
The presentation addresses the mechanochemical approach to solid-state synthesis, which proved to be indispensable for the solvent-free preparation of a great variety of molecular, ionic and metallic solid materials. The talk specifically focuses on the solid-state synthesis of rare earth-based metal organic frameworks (MOFs), which have a potential for becoming materials of choice for low temperature magnetocaloric systems that are under development at CaloriCoolTM. CaloriCoolTM is a newly established research consortium, which discovers, develops and deploys materials for magneto- electro- and elastocaloric cooling. It is a part of the DOE's Energy Materials Network (EMN) designed to accelerate innovation around the clean energy industries by addressing pressing materials challenges ranging from early development to manufacturing.
In the course of our research, we showed that the mechanochemical approach can be successfully applied to the preparation of MIL-78-type Metal Organic Frameworks. Contrary to the previous reports, the presence of a liquid (liquid assisted grinding) is not essential for the process. Thus obtained Gd-, Tb- and Dy- based MOFs showed short range magnetic order below 20 K; no long range order was observed down to 2 K. The magnetocaloric effect of Gd-based material was found to be comparable to the best known cryogenic refrigerants.
Our further investigations revealed that the mechanochemical methodology can be extended onto other rare earth-based hybrid organic-inorganic materials with substantial magnetocaloric effect at cryogenic temperatures. We also found that a catalyst which improves efficiency of mechanically driven reactions.
CaloriCoolTM is supported by the United States Department of Energy, Office of Energy Efficiency and Renewable Energy though its Advanced Manufacturing and Building Technologies Offices. Ames Laboratory is supported by the Office of Science, Basic Energy Sciences Programs and operated by Iowa State University under contract No. DE-AC02-07CH11358 with the United States Department of Energy.
Véronique Jubera
ICMCB-CNRS-University of Bordeaux ,France
Title: Highlight of spark plasma sintering effect through the structural study and luminescence properties of YNbO3:Eu3+
42 years-old, University of Bordeaux associate professor-HDR, over 70 publications in international journals. She is a specialist of luminescence of inorganic doped compounds. V. Jubera has been working as an associate professor at the ICMCB-CNRS, University of Bordeaux for 14 years. Her research topic deals with the structure-luminescence properties of crystallized materials. The luminescence spectroscopy is performed to evaluate the potentiality of phosphors for displays, lighting, sensing or lasers materials. She has been developing in the Institute, topics on the synthesis and characterization of massive (single crystals, transparent ceramics) innovative compounds as well as nano-powders. Her activities is fully included and supported by the competitiveness cluster "Routes des Lasers" and the cluster Laphia (IDEX Univ. de Bordeaux).
Recent developments in fast sintering processes makes possible to highly densify refractive materials. The application of these techniques in order to obtain transparent laser materials is promising and satisfying efficiencies have been recorded [1-4]. Concerning the Spark Plasma sintering process, the main constraint is to control the grain growth so as to avoid anisotropy and diffusion in the ceramic, thus cubic matrices are preferred.
The lattice of the Y3NbO7 phase is very interesting as it adopts a cubic symmetry being capable of incorporating a high proportion of rare earth doping elements, without charge compensation requirements. The oxygen vacancies are tolerated between 21-28% of niobium over cations (Nb/(Nb+Y)) ratio [5].
We propose to expose the structural study and luminescence properties of Eu3+ doped Y3NbO7 sintered by SPS. Indeed, the fast and high crystallization rate of the phase results in a composite pellet in which two different compositions in the solid solution range are stabilized. This result shows an unexpected lack of miscibility in the phase diagram which reflects the fact that the final composition is driven by the SPS conditions and the ratio between niobium and yttrium elements.
Mihaela Olaru
Petru Poni Institute of Macromolecular Chemistry, Romania
Title: Analysis and structural characterization of pigments and materials used in Nicolae Grigorescu heritage paintings
Dr. M. Olaru has a Ph.D within the field of synthesis of polyurethanes with different functional groups at "Gh. Asachi" Technical University from Iasi, Romania. She has a scientific experience embodied in over 35 papers published in reputed international/national scientific journals, 1 book and 4 chapter books published in national/international publishing houses, 1 patent, collaborator in over 15 national and 2 international projects, managerial experience gained through the coordination of 1 national and two international projects; scientific domains: photochemistry, polyurethanes, hybrid nanocomposites, cultural heritage, antimicrobial coatings; experience in synthesis and experimental data analysis.
Statement of the Problem: Knowledge about pigments applied in all types of paintings, especially in the case of ancient ones, is of great importance from both art history and conservation perspectives. Usually paint surfaces consist of several complex multilayers that can be altered due to aging or various degradation factors. The deterioration depends either on the paintings surrounding conditions or on the nature of the interactions between the constituting components. Identification of pigments and other materials employed in the creation of the paintings is necessary in order to acquire information regarding their provenance, author's painting style and methods or date of production. All these information is of major importance in selecting the most appropriate materials and methods for the artwork's future restoration. Nicolae Grigorescu is the most representative Romanian painter, being considered the founder of modern Romanian painting and the most important Romanian impressionist. He generated a comprehensive, original and unitary creation, spanning over almost 4000 paintings and drawings. Although his paintings rank first place in top 100 bestselling Romanian painters, there is no comprehensive work dealing with the identification and structural characterization of the pigments and materials used by him. The combination of various mobile, non-invasive techniques (IR reflectography technique, optical microscopy, XRF, Raman and NIR spectroscopies) and lab-based devices (FTIR and XPS spectroscopies, SEM-EDX microscopy) lead to the first exhaustive investigation of pigments and materials used by the famous Romanian painter Nicolae Grigorescu in three cultural heritage paintings. The study of a large number of spots and samples allowed a rigorous analysis and a far-reaching insight into his work. Conclusion & Significance: The present work is the first scientific paper that proves the use of natural ultramarine by a painter belonging to the impressionist school.
Olivier Toulemonde
ICMCB-CNRS-University of Bordeaux ,France
Title: The heterogeneous distribution of the transition metal oxidation states controls the magnetic and electronic properties of perovskite related oxides
Dr Olivier TOULEMONDE is working at the Institute for Solid State Chemistry Bordeaux (ICMCB) – CNRS - Université de Bordeaux since october 2005 as Assistant Professor. He became Associate Professor at University of Bordeaux in october 2006. His work is devoted to the study of the relationships between the nuclear structure and the magnetic properties of oxides materials and he especially highlights the key roles played by the charge transfert between transition metal cation. He is member of the cross functional axis related to exploratory solid state chemistry at ICMCB and elected member of the "Materials Chemistry" section of the CNRS since 2016.
Transition metal oxides with ABO3 and A2BO4 are known as perovskite-type and K2NiF4 type structures respectively. First, their ability to undergo reversible oxydo-reductions chemical reaction are technologically very attractive as electrodes in fuel cells (SOFC), as oxygen storage materials in anaerobic processes and as three way catalysts (TWC's). In addition, it is the control of oxygen released and/or up taken that opens ways towards huge change of their physical properties such as metal / insulator transition and/or antiferromagnetic to ferromagnetic transition.
When a single transition metal is introduced on the B crystallographic site, its oxidation state is indeed in direct relationship with the oxygen content. However, when two transition metal cations are introduced on the B crystallographic site, our recent results highlight that their relative oxidation states are closely related to a metal to metal charge transfer giving unexpected oxidation states distribution.
In SrFe0.5Co0.5O3-y materials, we highlight that the distribution of cobalt and iron oxidation states is heterogeneous, indicating that oxidation of cobalt cation requires higher oxidation potential than for the iron ones. We emphasize the correlation in between the exhibited paramagnetic to ferromagnetic transition around room temperature and oxidation state distributions and, used that fact to better analyze the giant exchange bias like properties exhibited by SrFe0.25Co0.75O2.63 material (see figure).
The influence of oxygen annealing in the electronic states for (Cu1-X MoX)Sr2RECu2O7+d (RE = Y, Er, Tm) has also been investigated. The predominance of the MoV oxidation state over the MoVI one on as-synthesized phases has been shown. But, annealing under flowing oxygen enhances both the MoVI and CuII amounts indicating molybdenum to copper charge transfer. Interestingly, the redox reaction related to the molybdenum to copper charge transfer is associated with a non-superconducting state to a superconducting state phase transition.
Varlei Rodrigues
University of Campinas, Brazil
Title: Using fused deposition modeling 3d printing for simplified fabrication of integrated microfluidic devices
Varlei Rodrigues has completed his PhD at the age of 28 years from Universidade Estadual de Campinas and postdoctoral studies from Ecole Polytechnique Fédérale de Lausanne. He has published more than 25 papers in reputed.
The preeminent control, manipulation and analysis of liquids at the submillimeter scale in microfluidics devices allowed the integration of research fields with emergent technologies such as lab-on-chips and organ-on-chips. Microfluidic devices based on Poly-Dimethylsiloxane (PDMS) shown a plethora of experimental possibilities due to good transparency, flexibility and ability to adhere reversibly and irreversibly to distinct materials, however, its cost and handling directed the field to search for new options. The simple, fast and efficient prototyping process offered by 3D printing technology makes the technique suitable across diverse applications, emerging it as an alternative to the traditional approaches. We will present the use of a home-made fused deposition modelling 3D printer for rapid prototyping of microchannels in Poly-Lactic Acid (PLA). We were able to 3D-print sealed PLA microchannels, achieving important features, such as good transparency, use of a thermoplastic (PLA) alternative to Poly-Dimethylsiloxane (PDMS) and easy integration of other materials during printing. In particular, flexible interdigitated electrodes were easily integrated within the microchannel, creating a microfluidic device within less than one hour. Finally, the 3D printing technology potentiates the field with more creative ideas and alternative materials for a rapid prototyping of complex structures, paving the way to more abundant developments.
