Finding fire and ice: Modeling the probability of methane hydrate deposits on the seafloor

News Article, March 25, 2021 • Sandia scientists use machine learning to find fuel source, climate-change driver Methane hydrate, an icelike material made of compressed natural gas, burns when lit and can be found in some regions of the seafloor and in Arctic permafrost. Thought to be the world’s largest source of natural gas, methane hydrate...

Materials developed at Sandia help extinguish solar panel fires before they ignite

News Article, December 22, 2020 • As solar panels become popular and their voltages increase, there is a need to have built-in capabilities to extinguish fires caused by arc-faults, which are high-power discharges of electricity that can create explosions or flash events due to damaged wires. Sandia National Laboratories researcher Kenny Armijo has spent 10 years...

Sandia Wins Funding for Two DOE-EERE Computer-Aided Battery-Safety R&D Projects

News Article, October 27, 2015 • Two recent energy storage modeling and simulation (mod/sim) R&D proposals developed by Scott Roberts (in Sandia’s Thermal/Fluid Component Sciences Dept.) have been funded. Sandia’s participation in these research activities stems from an ongoing Laboratory-Directed Research and Development (LDRD) joint computational/experimental project led by Anne Grillet (also in Sandia’s Thermal/Fluid Component...

Small Electric Voltage Alters Conductivity in Key Materials

News Article, July 1, 2015 • Using only a 9-volt battery at room temperature, a team led by Sandia researcher Jon Ihlefeld (in Sandia’s Electronic, Optical, & Nano Materials Dept.) has altered the thermal conductivity of the widely used material PZT (lead zirconate titanate) by as much as 11% at subsecond time scales. They did it...
