Passivation

Diamond coatings help reduce friction and wear on tools, bearings, and seals. Lubricating diamond with water considerably lowers friction. The reasons for this are not yet fully understood. The Fraunhofer Institute for Material Mechanics IWM in Freiburg and the Physics Institute at the University of more

Earth-abundant, cheap metals are promising photocatalytic electrode materials in artificial photosynthesis. A team of Chinese scientists now reports that a thin layer of titania beneath hematite nanorods can boost the performance of the photoanode. As outlined in their report, the nanostructured ele more

Lithium-air batteries are devices, producing power just out of air so they are also called lithium-oxygen batteries. Due to higher energy density they are much lighter than lithium-ion ones. Lithium-air batteries could prove to be much-needed, for instance, for increasing driving range of electric c more

The surface passivation in quantum dot sensitized solar cells (QDSSCs) plays a very important role in preventing surface charge recombination and thus enhancing the power conversion efficiency (PCE). ZnSe passivation with dopant in CdS/CdSe co-sensitized QDSSCs has been demonstrated an effective way more

Oxidation potentials of electrolyte molecules in Li–sulfur (Li/S) batteries and their variations in various solvent environments are investigated using first-principles calculations in order to understand oxidative decomposition reactions of electrolytes for cathode passivation. Electrolyte solvents more
