Graphene is Strong, But Is It Tough?
Graphene, a material consisting of a single layer of carbon atoms, has been touted as the strongest material known to exist, 200 times stronger than steel, lighter than paper, and with extraordinary mechanical and electrical properties. But can it live up to its promise?
Scientists Take Key Step Toward Custom-made Nanoscale Chemical Factories
Scientists have for the first time reengineered a building block of a geometric nanocompartment that occurs naturally in bacteria. The new design provides an entirely new functionality that greatly expands the potential for these compartments to serve as custom-made chemical factories.
Coupling 2 ‘Tabletop’ Laser-Plasma Accelerators, a Decisive First Step Toward Tomorrow’s Ultrapowerful Compact Machines
Scientists at Berkeley Lab’s BELLA Center demonstrated that a laser pulse can accelerate an electron beam and couple it to a second laser plasma accelerator, where another laser pulse accelerates the beam to higher energy—a fundamental breakthrough in advanced accelerator science.
Scientists Discover Protein’s Starring Role in Genome Stability, and Possibly Cancer Prevention
A protein called XPG plays a previously unknown and critical role helping to maintain genome stability in human cells. It may also help prevent breast, ovarian, and other cancers associated with defective BRCA genes.
Simplifying Solar Cells with a New Mix of Materials
Scientists have simplified the steps to create highly efficient silicon solar cells by applying a new mix of materials to a standard design. The special blend of materials eliminates the need for a process known as doping that steers the device’s properties by introducing foreign atoms. Doping can also degrade performance.
Moore Foundation Funds Berkeley Lab for Next-Generation Accelerators
Berkeley Lab researchers will receive $2.4 million from the Gordon and Betty Moore Foundation to develop compact free electron lasers that will serve as powerful, affordable x-ray sources for scientific discovery. This new technology could lead to portable and high-contrast x-ray imaging to observe chemical reactions, visualize the flow of electrons, or watch biological processes unfold.
Weaving a New Story for COFS and MOFs
An international collaboration led by Berkeley Lab scientists
has woven the first 3D covalent organic frameworks (COFs) from helical organic threads. The woven COFs display significant advantages in structural flexibility, resiliency and reversibility over previous COFs.
UC names Michael Witherell to head Lawrence Berkeley National Laboratory
The University of California Board of Regents today (Jan. 21) approved Michael Witherell, vice chancellor for research at UC Santa Barbara, as director of Lawrence Berkeley National Laboratory. Witherell is a leading physicist with a highly distinguished career in teaching, research and managing complex organizations.
Assessing the Impact of Human-Induced Climate Change
The past century has seen a 0.8°C increase in average global temperature, and according to the IPCC, the overwhelming source of this increase has been emissions of greenhouse gases and other pollutants from human activities. What remains unclear is precisely what fraction of the observed changes in these climate-sensitive systems can confidently be attributed to human-related influences, rather than mere natural regional fluctuations in climate. So Gerrit Hansen of the Potsdam Institute for Climate Impact Research and Dáithí Stone of Berkeley Lab developed and applied a novel methodology for answering this challenging question.
