Berkeley Lab researchers have achieved symmetry-breaking in a bulk metamaterial solution for the first time, a critical step game toward achieving new and exciting properties in metamaterials.
Researchers from Lawrence Berkeley National Laboratory, the University of California Berkeley, and Pacific Northwest National Laboratory have used a high-powered electron microscope to capture the birth of calcium carbonate crystals. It is a first step, the researchers say, to better understanding how it might be possible to pull excess carbon dioxide from the air and store it in rock where it wouldn’t contribute to global warming.
First Ab Initio Method for Characterizing Hot Carriers Could Hold the Key to Future Solar Cell Efficiencies
Danylo Zherebetskyy and his colleagues at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) found unexpected traces of water in semiconducting nanocrystals. The water as a source of small ions for the surface of colloidal lead sulfide (PbS) nanoparticles allowed the team to explain just how the surface of these important particles
Probing dopant distribution: Finding by Berkeley Lab Researchers at the Molecular Foundry Opens the Door to Better Doping of Semiconductor Nanocrystals
Berkeley Lab researchers at the Molecular Foundry have shown that when doping a semiconductor to alter its electrical properties, equally important as the amount of dopant is how the dopant is distributed on the surface and throughout the material.
The DOE’s David Danielson, Assistant Secretary for Energy Efficiency and Renewable Energy, was on hand in Berkeley April 14 to tour FLEXLAB™, the Facility for Low Energy experiments in Buildings, run by Berkeley Lab’s Environmental Energy Technologies Division. Danielson and Berkeley Lab Director Paul Alivisatos also met with executives from construction firm Webcor. Webcor’s testing in FLEXLAB will allow its engineers to predict and improve the energy performance for a new building constructed for biotech company, Genentech. A building mockup for Genentech will be studied at different building orientations, specific to the actual construction site. As part of his visit to the Lab, Danielson also toured the Molecular Foundry.
