ERC-Grant for research into new types of glass

In the coming five years, our group will be backed by the European Research Council through an ERC Consolidator Grant won by Lothar. The project "UTOPES" challenges today's engineering concepts for the generation of glassy materials towards the conception of new tools in glass processing. For that, melt deposition, isothermal deposition from liquid phases, and gas-phase deposition of non-crystalline materials will be treated - within the class of inorganic glasses - in a generalist approach, unified by the understanding that glass formation represents the only strict deviation from self-organization, and that, hence, the evolution of structural complexity in glassy materials can be tailored on any length-scale through adequate processing. Providing a topological scheme for the quantification and chemical tailoring of structural complexity, UTOPES will answer to the challenge of finding order in disorder, and will thus break the grounds for the third generation of glasses with properties beyond what is presently thought of as the limits of physical engineering.

Priority Programme 1594 on the development of ultrastrong glasses enters second phase

Following successful evaluation, German Science Foundation's priority program PP 1594 "Topological Engineering of Ultra-Strong Glasses" is embarking into its second 3-year period. The programme - coordinated by Lothar Wondraczek at the Laboratory of Glass Science - brings together scientists from all Germany, covering a broad range of research areas, to tackle the fundamental issues of elasticity, plasticity and material failure in disordered solids.

Solar spectral conversion in artificial and natural photosynthesis

Solar energy harvesting is often limited by the spectral sensitivity of the employed energy conversion system. In many applications, large parts of the solar spectrum do either not contribute to the harvesting scheme, or the full energetic potential of each photon cannot be put to use in the generation of electrical or chemical energy. Extrinsic sensitization through photoluminescent spectral conversion has been proposed as a route to at least partially overcome this problem. In a recent feature article which has been chosen for the cover page of Advanced Science, we discuss our related work in the emerging context of photochemical energy harvesting and storage through natural or artificial photosynthesis.
