of encapsulated high and low density water Towards multifunctionality and hierarchical complexity: examples for chemical adaptability and for a supramolecular chemical Darwinism, self-assembly of capsules into various patterns in different phases (e.g. blackberry-like hollow spherical assemblies as well as two- and three-dimensional structures) Müller's related work shows many applications (see above), for example, how cellular processes like ion-transport can be modelled based on the spherical porous capsules and how the latter can be used to remove toxic compounds from water. The compounds are studied worldwide by many groups especially in relation to potential applications in Materials Science (see Ref. and below). One aspect is modelling of the Lotus effect, another one is chemical adaptability as a new phenomenon. An interesting mathematical treatment of the Keplerates could be developed in relation to spherical viruses and Buckminster Fuller Domes based on Archimedean and Platonic solids. The unique range of potential applications of the Mo132 Keplerates has also been highlighted by several other authors, e.g.: "Thus, Keplerate-type capsules represent unique supramolecular objects offering a tunable spatially-restricted environment and promising in many domains such as catalysis, electric conductivity, non-linear optics, liquid crystals, vesicles and "blackberry" aggregates. ...a key point to promote confined space engineering." In another publication it is written: "Initiated and led by Müller and co-workers, the synthesis and structural characterization of protein-sized metal oxide clusters (2-6 nm) have generated great interest in the areas of physics, biology, chemistry, and materials science"; see also regarding a similar comment Ref. Some of the clusters can be obtained by planned synthesis, while the related derivative (also because of the structure of a Keplerate) Mo72Fe30 has unique magnetic properties. Personal Müller likes ancient Greek philosophy, classical music, and mountain hiking. He has a love for woodland birds since his early childhood, a pastime which his father cherished also.
