New Class of ‘Soft’ Semiconductors Could Transform HD Displays

New research by Berkeley Lab scientists could help usher in a new generation of high-definition displays, optoelectronic devices, photodetectors, and more. They have shown that a class of “soft” semiconductors can be used to emit multiple, bright colors from a single nanowire at resolutions as small as 500 nanometers. The work could challenge quantum dot displays that rely upon traditional semiconductor nanocrystals to emit light.

2-D Material’s Traits Could Send Electronics R&D Spinning in New Directions

Researchers created an atomically thin material at Berkeley Lab and used X-rays to measure its exotic and durable properties that make it a promising candidate for a budding branch of electronics known as “spintronics.”

Study Sheds Light on How Bacterial Organelles Assemble

Scientists at Berkeley Lab and Michigan State University are providing the clearest view yet of an intact bacterial microcompartment, revealing at atomic-level resolution the structure and assembly of the organelle’s protein shell. This work could benefit research in bioenergy and pathogenesis, and it could lead to new methods of bioengineering bacteria for beneficial purposes.

A Seaweed Derivative Could Be Just What Lithium-Sulfur Batteries Need

Lithium-sulfur batteries have great potential as a low-cost, high-energy, energy source for both vehicle and grid applications. However, they suffer from significant capacity fading. Now scientists from the Lawrence Berkeley National Laboratory have made a surprising discovery that could fix this problem.

Researchers Find a Surprise Just Beneath the Surface in Carbon Dioxide Experiment

X-ray experiments at Berkeley Lab, coupled with theoretical work, revealed how oxygen atoms embedded very near the surface of a copper sample had a more dramatic effect on the early stages of a reaction with carbon dioxide than earlier theories could account for. This work could prove useful in designing new types of materials to make reactions more efficient in converting carbon dioxide into liquid fuels and other products.

How X-rays Helped to Solve Mystery of Floating Rocks

Experiments at Berkeley Lab’s Advanced Light Source have helped scientists to solve a mystery of why some rocks can float for years in the ocean, traveling thousands of miles before sinking.

Scientists Help Thin-Film Ferroelectrics Go Extreme

Scientists have created the first-ever polarization gradient in thin-film ferroelectrics, greatly expanding the range of functional temperatures for a key material used in a variety of everyday applications. The discovery could pave the way for developing devices capable of supporting wireless communications in extreme environments.

Scientists Print Nanoscale Imaging Probe onto Tip of Optical Fiber

Combining speed with incredible precision, a team of researchers has developed a way to print a nanoscale imaging probe onto the tip of a glass fiber as thin as a human hair, accelerating the production of the promising new device from several per month to several per day.

Designing Cyclic Oligomers: Greater Than the Sum of Their Parts

-Written By Lida Gifford Cyclic proteins that assemble from multiple identical subunits (homo-oligomers) play key roles in many biological processes, including cell signaling and enzymatic catalysis and protein function. Researchers in Berkeley Lab’s Molecular Biophysics and Integrated Bioimaging (MBIB) Division worked with University of Washington’s David Baker, who led a team to design in silico
