Influence of wind on receivers for solar power towers [PDF]

, 2014
In solar thermal power towers an array of mirrors reflect the sunlight to the top of a tower, where it is absorbed by the so-called receiver heating up a fluid. The heat of the fluid is used afterwards. Since the receiver is exposed to the ambience, part of the energy is lost due to the emitted radiation and the convective losses of the hot surface. In

Enzyme‐Like Synthetic Cleft for Light‐Driven Water‐Oxidation Catalysis Via an Oxide Relay Pathway

Angewandte Chemie, EarlyView.
A carboxylic acid group introduced into the second coordination sphere of a Ru(bda) water oxidation catalyst forms a defined hydrogen bond within the catalytic cleft. This interaction locks the group in place and enables an intramolecular oxide relay pathway between Ru(V)═O and the carboxylate group, providing a distinct and efficient route for O─O ...
