New ultrathin semiconductor materials exceed some of silicon's 'secret' powers

ScienceDaily.com: Nanotechnology News - Fri, 08/11/2017 - 22:11
Chip makers appreciate what most consumers never knew: silicon's virtues include the fact that it 'rusts' in a way that insulates its tiny circuitry. Two new ultrathin materials share that trait and outdo silicon in other ways that make them promising materials for electronics of the future.

Nanofluidic energy conversion inspired by biology

NanoWerk.com - Fri, 08/11/2017 - 11:08
So far, bio-inspired energy conversion in solid-state nanofluidic devices has experienced three generations of evolution with the uptake of separate inspirations from biological ion channels, electric eels, and nacre. Here is an overview of the structural and functional evolution in synthetic one-dimensional and two-dimensional nanofluidic systems under the guidance of three different types of biological inspiration: the asymmetric ion-transport behaviors of biological ion channels, the strong bioelectric function of electric eels, and the layered microstructure of nacre.
