Angela Belcher: Using nature to grow batteries
Inspired by an abalone shell, Angela Belcher programs viruses to make elegant nanoscale structures that humans can use. Selecting for high-performing genes through directed evolution, she's produced viruses that can construct powerful new batteries,
Three layers of graphene reveals a new kind of magnet
However, in graphene -- one atom thick graphite -- the density of electrons is much smaller and can be changed by making a transistor. As a result of the low density of electrons the wave nature of electrons, as described by quantum mechanics, is eas
Toward all-solid lithium batteries
Most batteries are composed of two solid, electrochemically active layers called electrodes, separated by a polymer membrane infused with a liquid or gel electrolyte.
Surge in Utility Scale Battery Projects
Three massive battery storage plants--built by Tesla, AES Corp., and Altagas Ltd.--are all officially going live in southern California at about the same time.
Metallic Hydrogen update
Thomas D. Cabot Professor of the Natural Sciences Isaac Silvera and postdoctoral fellow Ranga Dias have long sought the material, called atomic metallic hydrogen.
A majorly better way of growing microalgae?
Among other things, microalgae is a potentially valuable source of biofuel. Unfortunately, however, growing it on a large scale can be a rather fussy process, making it less likely to be adopted commercially.
Semiconductor for next generation power electronics
Researchers have demonstrated the high-performance potential of an experimental transistor made of a semiconductor called beta gallium oxide, which could bring new ultra-efficient switches for applications such as the power grid, military ships and a
Creating atomic scale graphene nanoribbons
Silicon crystals are the semiconductors most commonly used to make transistors, which are critical electronic components used to carry out logic operations in computing.
