Scientists at Lawrence Livermore National Laboratory have shown that the structure of microscopic pores in high explosive materials can significantly impact performance and safety. These findings open the door to the possibility of tuning high explosives by engineering their microstructure.
The Department of Energy today announced the first round of awardees for the new HPC4Materials (HPC4Mtls) Program, a public-private effort aimed at using high-performance computing to advance U.S. industry’s discovery, design and development of materials for severe environments.
In a study published today in the journal Science Advances, Lawrence Livermore National Laboratory researchers, along with their counterparts at Harvard University, report on the hierarchical 3D printing of nanoporous gold, a proof of concept that researchers say could revolutionize the design of chemical reactors.
Secretary of Energy Rick Perry recognized LLNL chemist Bill McLean with a prestigious Secretary’s Achievement Award yesterday in recognition of “pioneering technical contributions that have led to significant advancements in science-based stockpile stewardship.”
Lawrence Livermore National Laboratory has issued a special High Performance Computing for Manufacturing (HPC4Mfg) call for proposals for projects aimed at addressing key challenges in U.S. steel and aluminum manufacturing. The solicitation officially opened on Aug. 23.
Swirling dense metallic hydrogen dominates the interiors of Jupiter, Saturn and many extra-solar planets. Building precise models of these giant planets requires an accurate description of the transition of pressurized hydrogen into this metallic substance – a long-standing scientific challenge. In a paper published by Science, a research team led by scientists at Lawrence Livermore National Laboratory describes optical measurements of the insulator-to-metal transition in fluid hydrogen, resolving discrepancies in previous experiments and establishing new benchmarks for calculations used to construct planetary models. The multi-institution team included researchers from the French Alternative Energies and Atomic Energy Commission, University of Edinburgh, University of Rochester, Carnegie Institution of Washington, University of California, Berkeley and The George Washington University.
Lawrence Livermore National Laboratory (LLNL), which manages the High Performance Computing for Manufacturing (HPC4Mfg) Program to use supercomputers to advance U.S. manufacturing, today announced the U.S. Department of Energy (DOE) has awarded nearly $3.8 million for 13 industry projects under the program.
Magnetic fields around a planet or a star can overpower the zonal jets that affect atmospheric circulation. New research by a Lawrence Livermore National Laboratory (LLNL) scientist and a collaborator from the Australian National University (ANU) provides a theoretical explanation for why self-organized fluid flows called zonal jets or “zonal flows” can be suppressed by the presence of a magnetic field.
Former LLNL director John Nuckolls has been named the fourth recipient of the John S. Foster Jr. Medal for his outstanding leadership in support of national security.
For the first time, scientists from Lawrence Livermore National Laboratory and five other organizations have shown that human influences significantly impact the size of the seasonal cycle of temperature in the lowest layer of the atmosphere.
A new study in which Lawrence Livermore National Laboratory scientists compared drug responses in the brains of rodents to drug responses of brain cells cultured in Lab-developed “brain-on-a-chip” devices may be a critical first step to validating chip-based brain platforms, LLNL researchers said.
Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) laser system has set a new record, firing 2.15 megajoules (MJ) of energy to its target chamber – a 15 percent improvement over NIF’s design specification of 1.8 MJ, and more than 10 percent higher than the previous 1.9 MJ energy record set in March 2012. Increasing NIF’s energy limit will expand the parameter space for stockpile stewardship experiments and provide a significant boost to the pursuit of ignition.
Through a new multi-year project involving the Department of Energy’s (DOE) Lawrence Livermore (LLNL), Lawrence Berkeley (LBNL) and Argonne (ANL) national laboratories, in collaboration with the Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) consortium led by the University of California, San Francisco (UCSF), scientists and engineers plan to simultaneously challenge DOE’s supercomputing resources, advance artificial intelligence capabilities and enable a precision medicine approach for traumatic brain injury (TBI).
The program to extend the life of the W80 nuclear warhead recently passed a significant milestone when the National Nuclear Security Administration (NNSA) gave passing grades to the plans to refurbish certain components and the proposed approach to developing component cost estimates.
After evaluation by an international peer review group, the L3-HAPLS advanced petawatt laser system has been declared fully integrated and operational at the ELI Beamlines Research Center in Dolní Břežany, Czech Republic. The group assessed the laser performance, determined that all performance parameters have been successfully met – capable of reaching the 1 petawatt, 10 hertz (Hz) design specification – and that the system is ready for integration with the experimental systems and first experiments.
Lawrence Livermore National Laboratory’s next-generation supercomputer Sierra is the third-fastest computing system in the world, according to the TOP500 list announced today at the International Supercomputing Conference in Frankfurt, Germany.
An experimental campaign conducted at the National Ignition Facility (NIF) – the world’s largest and most energetic laser – has achieved a total fusion neutron yield of 1.9e16 (1.9x1016) and 54 KJ of fusion energy output – double the previous record. The experiments utilized a diamond capsule – a layer of ultra-thin high-density carbon containing the deuterium-tritium (DT) fusion fuel. In addition to increased yield, the experiments achieved unprecedented pressures, exceeding those found at the center of the Sun.
A team of researchers led by Lawrence Livermore National Laboratory has developed a second way to use protein markers from human tissue to identify people – this time from human bones.
The Precision Reactor Oscillation and Spectrum Experiment (PROSPECT) has completed installation of a novel antineutrino detector that will probe the possible existence of a new form of matter – sterile neutrinos.
Americans used more solar and wind energy in 2017 compared to the previous year, according to the most recent energy flow charts released by Lawrence Livermore National Laboratory. Overall, energy consumption by the residential and commercial sectors dropped a bit.
