New Nanowire Could Enable More Efficient Superconducting Electronics

Superconductors -- materials that conduct electricity without resistance -- are remarkable. They provide a macroscopic glimpse into quantum phenomena, which are usually observable only at the atomic level. Beyond their physical peculiarity, superconductors are also useful. They're found in medical imaging, quantum computers, and cameras used with telescopes.

Si Swarf Wrapped by Graphite Sheets Used to Fabricate Li-Ion Battery Electrodes

Li-ion batteries (LIBs) are widely used in various mobile electronics. Concerns of global warming and climate change have recently boosted the demand for LIBs in electric vehicles and solar photovoltaic output smoothing. Si has been studied as an active material with a high theoretical capacity of 3578 mAh/g, which is around ten times higher than that of graphite (372 mAh/g).

New Polymer Improves Durability of Silicon Anodes for Li-Ion Batteries

Silicon anodes are known to considerably increase the capacity of Li-ion batteries, but their performance degrades quickly with use. Although polymeric coatings could be a solution to this problem, only a handful of studies have analyzed the mechanisms at play.

Single-Atom Catalysts Based on Cheaper Materials may be More Effective

Metals such as gold or platinum are often used as catalysts. In the catalytic converters of vehicles, for example, platinum nanoparticles convert poisonous carbon monoxide into non-toxic CO2. Because platinum and other catalytically active metals are expensive and rare, the nanoparticles involved have been made smaller and smaller over time.

New Method for Smashing Metal Nanoclusters to Form Super-Hard Metals

Metallurgists have all kinds of ways to make a chunk of metal harder. They can bend it, twist it, run it between two rollers or pound it with a hammer. These methods work by breaking up the metal's grain structure -- the microscopic crystalline domains that form a bulk piece of metal. Smaller grains make for harder metals.
