Superior hydrogen catalyst just grows that way

Scientists aim at bringing down the cost of hydrogen fuel cells by using a dirt-cheap compound to create an uneven surface that resembles a plant's leaves. The additional area helps catalyze hydrogen almost as efficiently as platinum.

Thermal gradients are shown to enhance spin transport in graphene

Researchers have demonstrated that the application of a thermal gradient in spintronic devices can cause spin signal to increase as a result of a novel thermoelectric phenomenon predicted and subsequently observed in graphene. Specifically, the enhanced spin signal is two orders of magnitude larger than anything previously reported for thermal effects in metals.
