Combining the characteristics of aqueous and organic electrolytes into a hybrid version increases VGN performance in supercapacitors, while KOH activation improves nanostructure and charge storage capacity.
Researchers have successfully measured some of the quantum properties of electrons in two-dimensional semiconductors. This work in the field of spintronics could one day lead to chips that are not only smaller but that also generate less heat.
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.
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.
