The International Union of Pure and Applied Chemistry officially approved new names for elements 114 and 116, the latest heavy elements to be added to the periodic table. Scientists of the Lawrence Livermore National Laboratory-Dubna collaboration proposed the names as Flerovium for element 114, with the symbol Fl, and Livermorium for element 116, with the symbol Lv, late last year.
The current method of removing the greenhouse gas carbon dioxide from the flues of coal-fired power plants uses so much energy that no one bothers to use it. So says Roger Aines, principal investigator for a team that has developed an entirely new catalyst for separating out and capturing carbon dioxide, one that mimics a naturally occurring catalyst operating in our lungs.
In experiments at SLAC National Accelerator Laboratory, a powerful X-ray laser blasted solid carbon crystals into a liquid and plasma even faster than expected, raising new questions about how these intense beams interact with matter. The tests took place at the Linac Coherent Light Source, or LCLS, using a pioneering technique to simultaneously blast and probe samples of graphite, a pure form of carbon.
For the first time, scientists have seen an X-ray-irradiated mineral go to two different states of matter in about 40 femtoseconds. Using the Linac Coherent Light Source (LCLS) X-ray Free-Electron Laser (XFEL) at SLAC National Accelerator Laboratory at Stanford University, Stefan Hau-Riege of Lawrence Livermore National Laboratory and colleagues heated graphite to induce a transition from solid to liquid and to warm-dense plasma.
The just-completed NDCX-II, the second generation Neutralized Drift Compression Experiment at the Lawrence Berkeley National Laboratory, is an unusual special-purpose particle accelerator built by the U.S. Department of Energy's Heavy Ion Fusion Science Virtual National Laboratory. The accelerator is a compact machine designed to produce a high-quality, dense beam that can rapidly deliver a powerful punch to a solid target.
A clear change in salinity has been detected in the world's oceans, signaling shifts and acceleration in the global rainfall and evaporation cycle tied directly to climate change, according to a recently published paper.
Lawrence Livermore National Laboratory has licensed its microbial detection array technology to a St. Louis, Mo.-based company, MOgene LC, a supplier of DNA microarrays and instruments. Known formally as the Lawrence Livermore Microbial Detection Array (LLMDA), the technology could enable professionals to detect within 24 hrs any virus or bacteria that has been sequenced and included among the array's probes.
A major effort to study a mysterious substance that could enhance understanding of the cosmos and fusion energy has received a critical boost from the Princeton Plasma Physics Laboratory (PPPL). Scientists at PPPL have designed and delivered a crucial component for a device that can heat a spot of foil to 30,000 C in less than a billionth of a second.
In mid-December 2011, Lawrence Livermore National Laboratory received a call from the Air Force Joint Space Operations Center (JSpOC). At the time, laboratory scientists were working with JSpOC to upgrade their command and control software. But this call was about something very different.
By looking at the way electrons are excited, researchers can gain a better understanding of the new field of transparent electronics. A Lawrence Livermore National Laboratory researcher has developed a new approach to investigate the interplay of excitonic effects and electron doping.
Intended to help cut red tape for business and startups wanting to do business with the U.S. Dept. of Energy’s research laboratories, the new Agreements for Commercializing Technology (ACT) program was recently launched as a third alternative to the two preceding options: signing a Cooperative Research and Development Agreement (CRADA) or a Work For Others (WFO) Agreement.
Researchers from the Lawrence Livermore National Laboratory and a team of American Indian scientists and engineers have partnered to study the possible use of Black Earth technology, or Cpryo, to help mitigate the uptake of radiocesium in locally grown foods in the Marshall Islands.
Extreme summer temperatures are already occurring more frequently in the United States, and will become normal by mid-century if the world continues on a business-as-usual schedule of emitting greenhouse gases, according to a Lawrence Livermore National Laboratory study.
In recent research using high-powered lasers, a Lawrence Livermore National Laboratory-led team has discovered that just as graphite can transform into diamond under high pressure, liquid magmas may similarly undergo major transformations at the pressures and temperatures that exist deep inside Earth-like planets. The findings provide a potential blueprint for planet formation.
Using models similar to those used in weapons research, scientists may soon know more about exoplanets, those objects beyond the realm of our solar system. In a new study, Lawrence Livermore National Laboratory scientists and collaborators came up with new methods for deriving and testing the equation of state of matter in exoplanets and figured out the mass-radius and mass-pressure relations for materials relevant to planetary interiors.
Conventional scientific wisdom says that the interatomic forces between ions that control high-temperature processes are insensitive to the heating of the electron "glue" that binds the ions together. In effect, traditional atomistic simulations ignore electron temperature completely. However, physicists at the Lawrence Livermore National Laboratory have shown how electron temperature has a surprisingly large impact on phase stability and melting in refractory transition metals.
Most astrophysicists stare at the night sky and look at stars. But Lance Simms from Lawrence Livermore National Laboratory looks at the blackness of night and knows there something else there. Simms has been working for a year on a NASA project called the Cosmic X-Ray Background Nanosatellite. The breadbox-sized satellite, set for an August launch, will gather X-ray data from the cosmos and beam it back to Earth.
By looking at the stability of the atmosphere, wind farm operators could gain greater insight into the amount of power generated at any given time. Power generated by a wind turbine largely depends on the wind speed. In a wind farm in which the turbines experience the same wind speeds but different shapes, such as turbulence, to the wind profile, a turbine will produce different amounts of power.
When a young man was advised to pursue a career in plastics in the 1967 movie, "The Graduate," people could not have envisioned one of the material's uses developed by Lawrence Livermore National Laboratory (LLNL) scientists. In a key discovery, a team of LLNL researchers has developed the first plastic material capable of efficiently distinguishing neutrons from gamma rays, something not thought possible for the past five decades or so.
Laboratory scientists have taken a crucial step toward describing thermonuclear reactions from first principles. Starting from a quantum mechanical system of five point-like nucleons and their mutual interactions, the team, for the first time, calculated within an ab initio framework, the cross sections for the deuterium-tritium and deuterium-3He fusion reactions.
Federally funded research can be a solution to some of the nation's top challenges, say government laboratory executives.
Lawrence Livermore National Laboratory's Erik Stenehjem speaks on topics including funding, peer review, entrepreneurship, nanotechnology research, and communicating research missions in a social networking environment.
As the percentage of wind energy contributing to the power grid continues to increase, the variable nature of wind can make it difficult to keep the generation and the load balanced. But recent work by Lawrence Livermore National Laboratory, in conjunction with AWS Truepower, may help this balance through a project that alerts control room operators of wind conditions and energy forecasts so they can make well-informed scheduling decisions.
In the first university-based planetary science experiment at the National Ignition Facility (NIF), researchers have gradually compressed a diamond sample to a record pressure of 50 Mbar (50 million times Earth's atmospheric pressure).
By focusing proton beams using high-intensity lasers, a team of scientists have discovered a new way to heat material and create new states of matter in the laboratory.
