Disorder enhances transport in 1D systems, calculations reveal

Physics World: Under the right conditions, the transport of electrical charges through wires with nanometre-scale thicknesses could become more efficient as disorder in the nanowire increases. This counterintuitive behaviour could be possible following a theoretical discovery made by physicists in Italy…

Biomaterials engineer Molly Stevens creates materials for tissue regeneration and ultrasensitive diagnostics

C&EN: Molly Stevens has long been driven by the hope that her research will change people’s lives. Toward the end of her PhD work in single-molecule biophysics, she heard…

Durable copper foam could replace flimsy face-mask filters

IMechE: A lightweight foam made of copper nanowires could offer efficient and durable air filtration for face masks, researchers have claimed. The team, from Georgetown University in Washington DC, said the recyclable and easily decontaminated material could also be used…

Gallium Oxide: The Supercharged Semiconductor

IEEE Spectrum: In the May 2002 issue of this magazine, the late Lester F. Eastman and Umesh K. Mishra made the case for what was then a long-shot technology in the world of power semiconductors: gallium nitride (GaN). They presented an…
