Discovery of New Semiconductor Holds Promise for 2D Physics and Electronics

March 20, 2014

Researchers at Berkeley Lab’s Molecular Foundry have discovered a unique new two-dimensional semiconductor, rhenium disulfide, that behaves electronically as if it were a 2D monolayer even as a 3D bulk material. This not only opens the door to 2D electronic applications with a 3D material, it also makes it possible to study 2D physics with easy-to-make 3D crystals.

Bright Future for Protein Nanoprobes

March 17, 2014

Berkeley Lab researchers at the Molecular Foundry have discovered surprising new rules for creating ultra-bright light-emitting crystals that are less than 10 nanometers in diameter. These ultra-tiny but ultra-bright nanoprobes should be a big asset for biological imaging, especially deep-tissue optical imaging of neurons in the brain.

Promising News for Solar Fuels from Berkeley Lab Researchers at JCAP

March 7, 2014

A JCAP study shows that nearly 90-percent of the electrons generated by a semiconductor/cobaloxime hybrid catalyst designed to store solar energy in hydrogen are being stored in their intended target molecules.

First Look at How Individual Staphylococcus Cells Adhere to Nanostructures Could Lead to New Ways to Thwart Infections

March 4, 2014

A team of researchers led by Berkeley Lab scientists have explored how individual Staphylococcus cells glom onto metallic nanostructures of various shapes and sizes that are not much bigger than the cells themselves. Their work could lead to a more nuanced understanding of what makes a surface less inviting to bacteria.

A Micro-Muscular Break Through

December 19, 2013

Berkeley Lab researchers have demonstrated a micro-sized robotic torsional muscle/motor made from vanadium dioxide that for its size is a thousand times more powerful than a human muscle, able to catapult objects 50 times heavier than itself over a distance five times its length faster than the blink of an eye.
