EPFL Scientists Use Perovskite Nanowires to Build Carbon-Nanotube Photodetector

EPFL scientists build the most sensitive carbon nanotube-based photodetector to date. The material is sensitized with CN3NH3PbI3 perovskite nanowires, which propel its responsivity by almost seven orders of magnitude.

Wrapping Silicon Sawdust in a Graphene Cage Improves Lithium-Ion Battery Performance

For years, scientists have been trying to use silicon to produce a lithium-ion battery anode capable of storing 10 times more energy than the existing commercial anodes, and making smaller and lighter batteries with superior performance. Previously there had been two major issues; silicon particles swell in size, and crack and break during the charging stage; and when they react with the electrolyte, they form a coating that decreases their performance.

Shape and Size Influence Reactivity in Catalytic Particles Comprising Of Only A Few Atoms

When margarine is produced, several tons of unsaturated fatty acids are converted from vegetable oils using hydrogen. When looking for improved catalysts for such hydrogenation reactions, a German-American research group discovered an effect that puts a 50-year old theory in question.
