Injecting Electrons Jolts 2-D Structure into New Atomic Pattern

The same electrostatic charge that makes your hair stand on end could be an efficient method to drive atomically thin electronic memory devices of the future. Scientists have found a way to reversibly change the atomic structure of a 2-D material by injecting it with electrons. The process uses far less energy than current methods for changing the configuration of a material’s structure. More>

Scientists Use Nanoparticle Supersoap to Create ‘Bijel,’ Potential Sculptable Liquid

A new type of “bijel” created by Berkeley Lab scientists could one day lead to applications in soft robotics, liquid circuitry, and energy conversion. Bijels hold promise as a malleable liquid that can support catalytic reactions and electrical conductivity, among other functions, but before this new work at Berkeley Lab, they had been notoriously difficult to make.

Hints From Hemoglobin Lead to Better Carbon Monoxide Storage

Carbon monoxide is an insidious poison because it loves the iron in our blood. This affinity for iron comes in handy in a newly created material that can absorb carbon monoxide far better than other materials, with potential applications in industrial processes like syngas production, where CO is a key player, and reactions where CO is an unwanted contaminant.

Michael Crommie and Alex Zettl Highlighted in DOE Blog

Electrons move through graphene more than 100 times faster than they do through silicon, but graphene is still difficult to use in modern electronics because it lacks a bandgap to direct where and when electrons flow. In this Aug. 30 article, the DOE’s Office of Science featured the efforts of Materials Sciences researchers Michael Crommie (far left) and Alex Zettl to get graphene’s electron traffic under control.

‘Cyborg’ Bacteria Deliver Green Fuel Source From Sunlight

Cyborg bugs that create potential fuels and plastics have been created by Berkeley Lab materials scientist Peidong Yang. The bugs are bacteria covered in tiny semiconductors that generate the chemicals from sunlight, carbon dioxide and water. Researchers have been attempting to artificially replicate photosynthesis for many years. More>
