DOE Office of Electricity Delivery & Energy Reliability (OE) Energy Storage Safety Workshop

On February 17–18, 2014, Sandia National Laboratories and Pacific Northwest National Laboratory co-hosted the DOE OE Energy Storage Safety Workshop in Albuquerque, NM. This workshop’s goal was to address the need for validated energy-storage safety as identified in the DOE strategic plan for “Grid Energy Storage.” Thought leaders in the fields of deployment, operation, regulation, […]

CINT Computer Simulation Guide for Designing Polymeric Nanoparticles Published

Gary Grest (in Sandia’s Nanostructure Physics Dept.) and his collaborators published “Internal Correlations and Stability of Polydots, Soft Conjugated Polymeric Nanoparticles” in ACS Macro Letters in July 2013. In their work, the internal structure of soft, highly luminescent nanoparticles was resolved by molecular dynamics (MD) simulations. This is the first-ever insight obtained that overcomes the […]

Sandia, Los Alamos, Superconducting Technologies Inc., & Superpower: Solution Deposition Planarization

The nation’s electricity grid relies on power transmission from the production source—be it a coal-fired plant, solar array, or wind farm—to the consumer. Long-distance transmission results in sizeable energy losses due to resistance in the conducting material. Superconducting wires offer the potential for zero power dissipation and higher maximum current densities when contrasted with traditional […]

Sandia Demonstrated First-Time, Single-Mode Lasing in Gallium-Nitride Nanowire Lasers

Semiconductor nanowire lasers have attracted intense interest as promising compact, low-power coherent light sources for on-chip applications, many of which (e.g., imaging, multiplex communica­tion, data storage) desire high beam quality and spectral purity—conditions that can be satisfied by single-mode operation in nanowire lasers. However, due to the lack of mode-selection mechanisms, most reported nanowire lasers exhibit […]

Sandia to Study the Little Things

The Center for Integrated Nanotechnologies at Sandia recently received a $900,000 grant to investigate the tiniest parts of solar materials. The new grant, announced by the U.S. Department of Energy in late August, will fund development of new microscopy tools to help understand the chemical and electronic structure of thin-film photovoltaic, or solar, materials and how microscopic […]
