Novel Nanoparticle Production Method Could Lead to Better Lights, Lenses, Solar Cells

Titanium-dioxide (TiO2) nanoparticles show great promise as fillers to tune the refractive index of anti-reflective coatings on signs and optical encapsulants (protective coverings or coatings) for light-emitting di­odes (LEDs), solar cells and other optical devices. Industry has shunned TiO2 nanoparticles because they have been difficult and expensive to make, and current methods produce particles that are too […]

Sandia/CINT Research on the Cover of Applied Physics Letters

A recent publication, “Few-hole double quantum dot in an undoped GaAs/AlGaAs heterostructure,” by Lisa Tracy (in Sandia’s Quantum Phenomena Dept.) and Terry Hargett and John Reno (both in Sandia’s Nanostructure Physics Dept.), was selected as the cover article for the current issue of Applied Physics Letters. They demonstrate a hole double quantum dot in an […]

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 […]
