Leading Edge Materials launches new project for graphene-enhanced battery anodes

Canada-based Leading Edge Materials (formerly Flinders Resources), a graphite mining company with principal assets located in Scandinavia, has announced the initiation of a new government-funded project entitled “Graphene Energy” which aims to apply graphene from the Company’s Woxna graphite facility to enhance the electrical conductivity and the mechanical strength of lithium ion battery anodes.

Bioinspired graphene membrane with temperature tunable channels for water gating and molecular separation

Smart regulation of substance permeability through porous membranes is highly desirable for membrane applications. Inspired by the stomatal closure feature of plant leaves at relatively high temperature, here the authors report a nano-gating membrane with a negative temperature-response coefficient that is capable of tunable water gating and precise small molecule separation.

Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell’s entryway act as miniature bouncers, letting in some electrically charged atoms—ions—but blocking others. Operating as exquisitely sensitive filters, these “ion channels” play a critical role in biological functions such as muscle contraction and the firing of brain cells. To rapidly transport the right ions through the cell membrane, the tiny […]

Is space like a chessboard?

Great article from the archive – Physicists at UCLA set out to design a better transistor and ended up discovering a new way to think about the structure of space. Space is usually considered infinitely divisible — given any two positions, there is always a position halfway between.

Growing Carbon: UW researchers derive graphene from coal

Wyoming-mined coal could be a cheap source for graphene — a material with implications for electronics, aerospace technologies and other industries — which has fascinated scientists for more than a decade. At least that’s the hope of some researchers at the University of Wyoming who are investigating methods for “growing” graphene and other useful carbon materials […]
