Breaking the Law: Lawrence Livermore, Department of Energy look to shatter Moore's Law through quantum computing

March 19, 2018- 
The laws of quantum physics impact daily life in rippling undercurrents few people are aware of, from the batteries in our smartphones to the energy generated from solar panels. As the Department of Energy (DOE) and its national laboratories explore the frontiers of quantum science, such as calculating the energy levels of a single atom or how molecules fit together, more powerful tools are a...

FSC earns 8th straight A in OPCW tests

March 14, 2018- 
During its 15 years as a certified laboratory for the Organization for the Prohibition of Chemical Weapons (OPCW), a score of Lawrence Livermore National Laboratory (LLNL) chemists have developed some first-rate habits. One of them is earning A grades on the organization's environmental proficiency tests. In recently announced results, LLNL earned its eighth straight A grade during last fall...

Lab scientists to improve energy efficiency of copper catalysts that convert CO2 to methane

March 8, 2018- 
Lawrence Livermore National Laboratory (LLNL) researchers have received $1 million from the Department of Energy to improve the energy efficiency of copper-based catalysts to convert carbon dioxide into methane and other valuable hydrocarbon products. Led by LLNL’s Juergen Biener, the project will help meet the nation’s future energy needs by converting low-cost, abundant resources into...

Lab employee and retiree named fellows

March 2, 2018- 
Two researchers affiliated with Lawrence Livermore National Laboratory (LLNL) -- a current employee and a retiree -- have been named fellows of the international Combustion Institute (CI). Bill Pitz, a combustion scientist in the Lab’s Materials Science Division, and Charlie Westbrook, a retired Lab employee, were announced in mid-February as fellows of the institute. They are members of the...

Earth's core metals react well to electrons

March 1, 2018- 
At temperatures and pressures found on Earth’s surface, metallic elements are electropositive and lose their valence electrons to form positively charged cations. Metals have free electrons that naturally form compounds with electronegative elements. For example, iron reacts with oxygen to form Fe2O3 – commonly referred to as rust. In contrast, noble gas elements (NGEs), such as argon, neon...

Scientists find 'frustration' in battery materials

Feb. 22, 2018- 
Adding carbon atoms to a new type of solid lithium ion battery could make it charge faster and more safely. Solid-state lithium-ion batteries can provide dramatically improved safety, voltage and energy density compared with today’s batteries, which use liquid components. They could be used in electric vehicles, as well as in power electronics. However, they are still in an early stage of...
