Livermore and Russian scientists propose new names for elements 114 and 116
The International Union of Pure and Applied Chemistry (IUPAC) today recommended new proposed names for elements 114 and 116, the latest heavy elements to be added to the periodic table. Scientists of the Lawrence Livermore National Laboratory (LLNL)-Dubna collaboration proposed the names as Flerovium for element 114 and Livermorium for element 116. In June 2011, the IUPAC…
Unclassified computing scales to new heights
Unclassified high performance computing at the Laboratory will scale new heights with the recent installation of Sierra, a Dell supercomputing system.Clocking in at a peak speed of 261 teraFLOP/s (trillion floating operation per second), Sierra will become the most powerful high performance computing (HPC) resource available for unclassified research at LLNL. The new…
Learning from climate's sedimental journey
By analyzing sediments up to 4,000 years old, Susan Zimmerman is hoping to provide a tool to help predict future climate change.Ancient records of what was happening with climate conditions can be used with regional climate models to tell a story of what happened in the past and to correlate it to the present and the future. Current models typically use data only for the…
Forensics helps NPS officer detect his niche
Major Bill Short's time at the Laboratory may turn out to be brief, but he believes it just might stand out as one of the most valuable experiences of his career.With 20 years of service in the U.S. Marine Corps, Short enrolled in the Naval Postgraduate School (NPS) in Monterey. There he learned about an LLNL research opportunity in the area of standoff detection of…
New accelerator is smash hit with Lab scientists
In the start of an experiment physicists believe will help resolve basic questions about the nature of the universe, the first proton beam was circulated Wednesday through the 17-mile-long Large Hadron Collider, the world’s most powerful particle accelerator. Located at the CERN particle physics research center near Geneva, Switzerland, the Large Hadron Collider (LHC) is a…
LLNL researchers peer into water in carbon nanotubes
LIVERMORE, Calif. – Researchers have identified a signature for water inside single-walled carbon nanotubes, helping them understand how water is structured and how it moves within these tiny channels.This is the first time researchers were able to get a snapshot of the water inside the carbon nanotubes.Single-walled carbon nanotubes (SWCNTs) offer the potential to act as…
