Catalysis is the process of speeding up a chemical reaction; it’s very important for many technologies. Branched nanoparticles are one of the most promising catalysts.
Scientists can control their branch sizes and surfaces to make them more stable and more effective catalysts.
Hokkaido University researchers have devised a unique approach for making nanosized semiconductors on a metal surface. The details of the method were reported in the journal Nano Letters (« Localized ZnO Growth on a Gold Nanoantenna by Plasmon-Assisted Hydrothermal Synthesis ») and could further research into the fabrication of nanosized light and energy emitters.Lire la suite
Static electricity shock which occurs more often in winter is unpleasant. When two different objects are in repeated contact, it causes friction which then creates static electricity.Lire la suite
Scientists from the Skoltech Center for Energy Science and Technology (CEST) and the Institute for Problems of Chemical Physics of Russian Academy of Sciences have developed a novel approach for preparing thin semiconductor fullerene films.Lire la suite
It is vital for the procedure in-situ to be observed in many high vacuum and ultra-high vacuum (HV/UHV) processes. The challenge is that any optical component must penetrate the hermetically sealed chamber but not compromise the quality of the vacuum.Lire la suite
Researchers at the University of Antwerp report how higher-order periodic modulations called supermoiré caused by the encapsulation of graphene between hexagonal boron nitride affect the electronic and structural properties of graphene, as revealed in three recent independent experiments.Lire la suite
Quantum teleportation shows remarkable promise as being critical for the production of semiconductors in the future. The problem lies in trying to understand and transmit information via quantum entanglement.Lire la suite
The first hours of a lithium-ion battery’s life largely determine just how well it will perform. In those moments, a set of molecules self-assembles into a structure inside the battery that will affect the battery for years to come.Lire la suite
Scientists at Tokyo Institute of Technology have shown that copper oxide particles on the sub-nanoscale are more powerful catalysts than those on the nanoscale. These subnanoparticles can also catalyze the oxidation reactions of aromatic hydrocarbons far more effectively than catalysts currently used in industry.Lire la suite
