Sandia receives ARPA-e funding to monitor plant roots for drought and heat tolerance

Multi-Modal Monitoring of Plant Roots for Drought and Heat Tolerance in the U.S. Southwest – $2,400,000 The Sandia National Laboratories team will develop a set of technologies to link below ground carbon partitioning with aboveground photosynthetic measurements. They will use microneedle sensor technology, originally developed for medical applications such as glucose level monitoring, to non-destructively [...]

Controlled Self-Assembly in Ternary Polymers

Top Left: Schematic of ternary polymer monolayers. Top Right: AFM images of experimental systems, at different polymer fractions, compared with corresponding SCFT calculations. Bottom: phase diagram. Scientific Achievement By creating a dense layer with three types of polymer molecules bound to a surface, we have demonstrated unique self-assembled patterns both theoretically and experimentally.

Pressure-Directed Assembly: new opportunity for nanoscience

(Fred Kavli Distinguished Lectureship in Nanoscience award presentation by Hongyou Fan at the 2015 MRS Spring Meeting) Pressure modulates balanced interactions in self-assembled nanoparticle arrays (a), enables formation of 1-3 dimensional nanostructures (c). In-situ structural (d,e) and optical (f) interrogation show correlation and consistency with phase transition processes (e,g) and formation of the nanostructures [...]

Sandia Researchers Win Best Paper Award from the American Institute of Aeronautics and Astronautics

Researchers Joe Oefelein and Guilhem Lacaze (both in Sandia’s Reacting Flow Research Dept.) won the American Institute of Aeronautics and Astronautics’ (AIAA’s) best paper award for their work on scramjet engine simulations. The paper, “A Priori Analysis of Flamelet-Based Modeling for a Dual-Mode Scramjet Combustor,” was a collaboration with Jesse Quinlan and James McDaniel (Univ. [...]

Detecting rare, abnormally large grains by x-ray diffraction

The theme of the Nanomechanics and Nanometallurgy of Boundaries project at Sandia National Labs is to understand the connection between mechanical deformation and grain boundary instability in nanocrystalline metals. Our prior observations have led to the hypothesis that fatigue-induced abnormal grain growth is a precursor to crack initiation in nanocrystalline metals [Padilla et al, Metall. [...]

Phase Field model elucidates competing thermodynamic effects on nanocrystalline stability

Recent experimental and theoretical results suggest that nanocrystalline metals can be thermodynamically stabilized by the free energy gain associated with the segregation of solute atoms to the grain boundary which will reduce grain boundary energy and so the driving force for nanocrystalline coarsening. A detail understanding of this proposed mechanism requires detangling the thermodynamics of [...]
