Scientists measure how unpaired electrons in atoms at one end of a molecule can drive chemical reactivity on the molecule’s opposite side. This work shows how molecules containing these so-called free radicals could be used in a whole new class of reactions.
Scientists have developed a new way to guide the self-assembly of a wide range of novel nanoscale structures using simple layered block copolymers as starting materials.
Chi-Chang Kao has decided to return to research after serving 10 years as director of the Department of Energy’s (DOE) SLAC National Accelerator Laboratory. He will continue in the lab director role until a replacement is found.
The 7th African School of Fundamental Physics and Applications (ASP) will be held in-person at Nelson Mandela University in Gqeberha, South Africa, from November 28 to December 9, 2022. Teams of leading physicists from U.S. Department of Energy (DOE) national laboratories and universities and other institutions across the U.S., Europe, Asia, and Africa will introduce more than 70 African graduate students to physics theories, experiments, and technologies.
Nuclear physicists studying particle collisions at the Relativistic Heavy Ion Collider (RHIC) have new evidence that particles called gluons reach a steady “saturated” state inside the speeding ions.
Particle physics changed forever on July 4, 2012. That was the day the two major physics experiments at CERN’s Large Hadron Collider (LHC), CMS and ATLAS, jointly announced the discovery of a particle that matched the properties of the Higgs boson—a particle theorized decades earlier. The discovery cemented the final piece in the Standard Model of particle physics. Now physicists from the CMS and ATLAS Collaborations detail high-precision results from their latest Higgs boson studies.
Scientists studying particle collisions at the Relativistic Heavy Ion Collider (RHIC) have revealed how certain particle-jets lose energy as they traverse the unique form of nuclear matter created in these collisions. The results should help them learn about key transport properties of this hot particle soup, known as a quark-gluon plasma (QGP).
Nestled 30 feet underground in Menlo Park, California, a half-mile-long stretch of tunnel is now colder than most of the universe. It houses a new superconducting particle accelerator, part of an upgrade project to the Linac Coherent Light Source (LCLS) X-ray free-electron laser at the Department of Energy’s SLAC National Accelerator Laboratory.
Imagine a computer that can think as fast as the human brain while using very little energy. That’s the goal of scientists seeking to discover or develop “neuromorphic” materials that can send and process signals as easily as the brain’s neurons and synapses. In a paper just published scientists describe surprising new details about vanadium dioxide, one of the most promising neuromorphic materials.
The new Atlantic Marine Energy Center (AMEC), led by the University of New Hampshire in partnership with several East Coast universities, has been awarded $9.7 million over four years from the U.S. Department of Energy (DOE). The center will focus on research and development to address ongoing needs for sustainable renewable ocean energy. It will be one of only four National Marine Renewable Energy Centers (NMREC) in the country.
The Princeton Plasma Physics Laboratory announced that accomplished engineer Ruben Fair, has been named head of the ITER Department, heading PPPL’s ITER Team, which is focused on the design and fabrication of six diagnostics for the international fusion experiment.
Scientists studying the biochemistry of plant cell walls have identified an enzyme that could turn woody poplar trees into a source for producing a major industrial chemical. The research, just published in Nature Plants, could lead to a new sustainable pathway for making “p-hydroxybenzoic acid,” a chemical building block currently derived from fossil fuels, in plant biomass.
Scientists studying particle collisions at the Relativistic Heavy Ion Collider have produced definitive evidence for two physics phenomena predicted more than 80 years ago: that matter/antimatter can be generated directly from collisions of photons and that a magnetic field can bend polarized light along different paths in a vacuum.
What do you need to study the fine details of the building blocks of matter? A new kind of particle accelerator called an Electron-Ion Collider, planned to be built in the United States over the next decade, and a state-of-the-art detector to capture the action when electrons and ions collide.
A new analysis of collisions conducted at different energies at the Relativistic Heavy Ion Collider (RHIC) shows tantalizing signs of a critical point—a change in the way that quarks and gluons, the building blocks of protons and neutrons, transform from one phase to another. The findings will help physicists map out details of these nuclear phase changes to better understand the evolution of the universe and the conditions in the cores of neutron stars.
To address PPE shortages during the pandemic, scientists at Berkeley Lab and UC Berkeley are developing a rechargeable, reusable, anti-COVID N95 mask and a 3D-printable silicon-cast mask mold.
