Supercomputer simulations of super-diamond suggest a path to its creation
Diamond is the strongest material known. However, another form of carbon has been predicted to be even tougher than diamond. The challenge is how to create it on Earth. The eight-atom body-centered cubic (BC8) crystal is a distinct carbon phase: not diamond, but very similar. BC8 is predicted to be a stronger material, exhibiting a 30% greater resistance to compression…
Hard as a rock, LLNL to study geologic hydrogen production
Lawrence Livermore National Laboratory (LLNL) has received $1 million to explore technologies that stimulate hydrogen production from mineral deposits found in the subsurface, including developing our understanding of hydrogen-producing geochemical reactions and how to enhance or control the rate of hydrogen production. The use of hydrogen fuel to offset fossil fuel…
Energy I-Corps experience shines light on bringing specialty resin to the silicone 3D-printing market
In the fall of 2023, Lawrence Livermore National Laboratory (LLNL) scientists Sijia Huang and Michael Ford participated in the Department of Energy’s Energy I-Corps Program, an immersive eight-week entrepreneurial boot camp that teaches scientists and engineers the tools of the trade for commercializing technology from the Lab to the marketplace. A major part of the…
‘Science on Saturday’ extends into March in Tracy
Lawrence Livermore National Laboratory’s (LLNL) popular outreach series, “Science on Saturday,” will continue its programming into March at the Grand Theatre Center for the Arts in Tracy, California. The talks are scheduled for March 2 and 9 and will focus on the theme “Magic of Materials.” The talks, which are geared toward middle and high school students, will begin at…
Lab employees recognized with Secretary of Energy’s Honor Awards
Lawrence Livermore National Laboratory (LLNL) employees, participating in five project teams, recently earned Department of Energy (DOE) Secretary’s Honor Awards. In addition, Karin King of the Livermore Field Office was honored for her role in the Leadership in Climate Action Team. Representing some of the highest internal, non-monetary recognition that DOE employees and…
Hot stuff: A new thermal pathway for a high explosive
TATB (1,3,5-triamino-2,4,6-trinitrobenzene) is an important explosive compound because of its extensive use in munitions and world-wide weapons systems. Despite its importance, researchers have been trying to understand its response to temperature extremes for the past 50 years. A Lawrence Livermore National Laboratory (LLNL) team has uncovered a new thermal decomposition…
Looking at the importance of catalyst sites in electrochemical CO2 conversion
Intense research efforts have been directed toward studying the electrochemical conversion of CO2, a major greenhouse gas, into platform chemicals and fuels. The success of this technology can enable decarbonization of some of the largest CO2 emitters including steel, cement and chemical manufacturing industries. Copper is unique in its ability to convert CO2 at low…
Strategic Deterrence Academic Collaboration Team awards six scientists to support collaborative research
Six scientists at the Lawrence Livermore National Laboratory (LLNL) were recently granted awards through the Lab’s 2023 Academic Collaboration Team (ACT) annual call for proposals. Awards support university research partners for up to three years to perform research in collaboration with Lab scientists and offer an important way to build long-term connections with…
Microbial research unravels a global nitrogen mystery
Ammonia-oxidizing microorganisms (AOM) use ammonia for energy and account for the annual oxidation of approximately 2.3 trillion kilograms of nitrogen in soil, freshwater, the subsurface and man-made ecosystems. But one major question that has remained unanswered for decades is how different AOM species coexist in the same environment: do they compete for ammonia or…
Underneath it all: building a better understanding of carbon use by soil microbes
Microbes are major drivers of carbon and nutrient fluxes in Earth’s terrestrial ecosystems; however, Earth system models used for climate change adaptation and mitigation strategies typically exclude explicit representation of soil microorganisms. A team of researchers from Lawrence Livermore National Laboratory (LLNL), Lawrence Berkeley National Laboratory (LBL) and…
Using agricultural residues for fuel and chemicals
A Lawrence Livermore National Laboratory (LLNL) scientist is part of a research team shedding new light on how to access the sugars locked up in plant materials in order to convert byproducts into new feedstocks for production of fuels, materials and chemicals. Converting grasses, weeds, wood and other plant residues into sustainable products normally produced using…
Lawrence Livermore’s popular 'Science on Saturday' lecture series returns to Las Positas College
Lawrence Livermore National Laboratory's (LLNL) popular lecture series, “Science on Saturday,” returns Feb. 3 and runs through Feb. 24. The series offers four different lectures with the theme, “Magic of Materials.” Each lecture is presented by leading LLNL researchers who are joined by high-school science teachers. Below is the schedule of lectures, which can also be…
Synthetic antibacterial minerals combat topical infections
The development of new antibiotics has stalled — new strategies are needed as the world enters the age of antibiotic resistance. To combat this challenge, Lawrence Livermore National Laboratory (LLNL) scientists have found that synthetic antibacterial minerals exhibit potent antibacterial activity against topical MRSA infections and increase the rate of wound closure…
The hidden symphony of soil: decoding viral dynamics and microbial mortality after the first rainfall
Soil is a highly complex microbial habitat that is home to tens of millions of microbial populations, where biotic and abiotic factors shape microbial community structure. Moments of acute pressure on a community, such as rapid environmental changes or fluxes in resource availability, drive successional trajectories that result in altered community structures. One such…
New study reveals surprising behavior of iron under extreme conditions
Iron is one of the world’s most abundant elements and a primary component of the Earth's core. Understanding the behavior of iron under extreme conditions, such as ultra-high pressures and temperatures, has implications for the science of geology and the Earth’s evolution. In a study conducted by a team led by Lawrence Livermore National Laboratory. researchers combined…
Two LLNL Physicists named American Physical Society Career Mentoring Fellows
PLS staff physicists Ben Zhu and Veronika Kruse were selected by the American Physical Society (APS) as Career Mentoring Fellows for 2023-2024. Ben belongs to PLS’s Fusion Sciences program and Veronika is in the High Energy Density Science section. Part of their duties involve attending selected APS conferences such as the Division of Plasma Physics (DPP) meeting,…
New analysis outlines national opportunities to remove CO2 at the gigaton scale
Lawrence Livermore National Laboratory (LLNL) researchers, along with scientists from more than a dozen institutions, have completed a first-of-its-kind high-resolution assessment of carbon dioxide (CO2) removal (CDR) in the United States. The report, “Roads to Removal: Options for Carbon Dioxide Removal in the United States,” charts a path for the United States to achieve…
Resolving astronomical mysteries
