Electron Transfer Theory in Single Molecule Studies of Intermittent Fluorescence of Quantum Dots and in Initial Steps in Dye Sensitized Solar Cells
Intermittently fluorescing single molecule systems are found in many materials, including semiconductor quantum dots (QD), dyes on crystalline or nanoparticle film surfaces, and biological systems. The QD's show a ~ -3/2 power law for the distributio....

Quasicrystals - or, as Shechtman would prefer, quasi-periodic materials - now have scientists thinking about matter in a new light, but they also have many possible practical applications. Because of their uneven structure, quasicrystals do not have ....

This lecture addresses the question if spatio-temporal self-organisation of matter which is so characteristic for living systems can also be verified with a simple inorganic reaction in which the observed phenomena of complexity can be traced back to....
More details | Watch nowRoles of the Ubiquitin System in Health and Disease
The selective degradation of many short-lived proteins in eukaryotic cells is carried out by the ubiquitin-mediated proteolytic system. In this pathway, proteins are targeted for degradation by covalent ligation to ubiquitin, a highly conserved small....
