RSC Corday Morgan Award Lecture - Solar-driven Reforming of Waste Polymers for the Synthesis of Sustainable Fuels and Chemicals
Speaker: Erwin Reisner (Cambridge)
The synthesis of solar fuels and chemicals through artificial photosynthesis allows the direct pairing of light absorption to drive chemical redox processes. This approach is a one-step and versatile alternative to the more indirect coupling of a photovoltaic cell with electrolysis and enables potentially the synthesis of a wide range of fuels and feedstock chemicals. A common drawback in most artificial photosynthetic systems and organic photocatalysis is their reliance on expensive materials and device architectures, which challenges the development of ultimately scalable devices. Another limitation in many approaches is their inefficiency and reliance on sacrificial redox reagents, which may be system damaging and often prevent truly energy-storing chemistry to proceed. This presentation will give an overview about our recent progress in developing semiconductor suspension systems to perform efficient full redox cycle solar catalysis with inexpensive components, and our approach for sustainable waste polymer (biomass and plastics) photoreforming and fine chemical synthesis.

RSC Soft Matter and Biophysical Chemistry Award Lecture - Materials Chemistry to Mimic Living Matter
Speaker: Prof Samuel Stupp (Northwestern University)
Materials Chemistry to Mimic Living Matter Samuel I. Stupp Departments of Chemistry, Materials Science & Engineering, Medicine, and Biomedical Engineering Simpson Querrey Institute for Bio -Inspired Science and Technologies Northwestern University
One of the grand challenges in materials chemistry is the search for synthetic supramolecular systems that could mimic the behaviors of living matter . Advances in this frontier could yield materials that impact health , energy, and environment al protection technologies. The design of molecular motions and the discovery of mechanisms for reversible formation of structure, particularly hierarchical ones, are of fundamental importance in this area. A remarkable biological example is the dynamic formation and di sassembly of supramolecular polymers in the cytoskeleton of cells. Ideally such biomimetic reversible behavior in synthetic soft matter would occur at constant temperature through the addition of chemicals or the use of other external stimuli. This lecture will report on the development of biomolecular systems that mimic protein ligands to signal cells or organize reversibly into superstructures upon addition of molecules . Of relevance to energy and the environ ment, the lecture will also discuss photocatalytic synthetic systems inspired by the photosynthetic machinery of green plants, and others that respond to light or magnetic fields to acquire robotic functions .
