Rechargeable lithium air batteries could save a lot of weight, if only they could be made to work. Now MIT has proved another hopeful additive is flawed, although the understanding developed could help in the search for others. Like zinc-air non-rechargeables, the idea is to replace one energy-containing electrode material with oxygen, which is breathed ...

Georgia Tech chemists have developed water-based electrochromic film inks for colour-change applications such as auto-dimming rear-view car mirrors. “There were some hurdles to pulling it off,” said GaTech. “The finished product had to electrically operate comparable to films that are applied in an organic solvent, and also be water-resistant in spite of the water-based production.” ...

Clean graphene be set free without damage to its growth substrate, using only simple safe chemicals, according to researchers at the University of Illinois at Urbana-Champaign – aiming to release it for use in flexible transparent electronics. The 2D material is synthesised using chemical vapour deposition onto a metal substrate, typically copper foil. “One particularly ...

Toshiba has announced a family of CMOS low drop-out (LDO) regulators. Called TCR4DG, they have an on-off control input and come in in fixed output voltages between 1.0 and 4.5V, at up to 420mA. Typical drop-out is 193mV (420mA, 3.3Vout). Low output noise voltage is claimed, and as befitting a Japanese company, the claim is ...
