Advanced Materials Sandia researchers first to measure thermoelectric behavior by 'Tinkertoy' materials
Sandia National Laboratories researchers have made the first measurements of thermoelectric behavior by a nanoporous metal-organic framework, a development that could lead to an entirely new class of materials for such applications as cooling computer chips and cameras and energy harvesting. The results were published in 'Thin Film Thermoelectric Metal-Organic Framework with High Seebeck Coefficient and Low Thermal Conductivity,' which appeared April 28 online in Advanced Materials.

Blood Starving cancer cells instead of feeding them poison
An enzyme-drug that prevents the essential nutrient asparagine from reaching cancer cells seem an effective way to kill them, but that enzyme-drug also does away with the nutrient glutamine that all cells need. Now a simulation has directed the mutation of the enzyme so that, in wet labs, it left normal cells unharmed in Petri dishes and cancer cells dead in test tubes. Lab tests are underway with mice. If successful, human tests are next.

Sandia National Laboratories has begun making silicon wafers for three nuclear weapon modernization programs, the largest production series in the history of its Microsystems and Engineering Sciences Applications complex.
Public Release: 19-Mar-2015 Explosive Destruction System begins first stockpile project
This week the Explosive Destruction System (EDS), designed by Sandia National Laboratories for the US Army, began safely destroying stockpile chemical munitions. The project to destroy 560 chemical munitions at the US Army Pueblo Chemical Depot in Colorado with EDS is a prelude to a much larger operation to destroy the stockpile of 780,000 munitions containing 2,600 tons of mustard agent, stored at the Pueblo depot since the 1950s.
Public Release: 19-Mar-2015 Sandia showcases biology breakthroughs available for licensing
Technologies developed in Sandia National Laboratories' biosciences program could soon find their way into doctors' offices -- devices like wearable microneedles that continuously analyze electrolyte levels and a lab-on-a-disk that can test a drop of blood for 64 different diseases in minutes. At a recent seminar for potential investors and licensees, part of the Sandia Technology Showcase series, Sandia bioscientists presented eight ready-to-license technologies in three key areas: medical diagnostics, biosurveillance and therapeutics and drug discovery.

Nature Geoscience Iron rain fell on early Earth, new Z machine data supports
Physical tests at Sandia's Z machine reveal that, at pressures rivaling those when worlds collide, iron vaporizes at far lower pressures than assumed by theoreticians, explaining why the element is distributed in Earth's mantle rather than collected at its core.

Science Direct measurement of key molecule will increase accuracy of combustion models
Sandia National Laboratories researchers are the first to directly measure hydroperoxyalkyl radicals -- a class of reactive molecules denoted as 'QOOH' -- that are key in the chain of reactions that controls the early stages of combustion. A paper describing the work, performed by David Osborn, Ewa Papajak, John Savee, Craig Taatjes and Judit Zádor at Sandia's Combustion Research Facility, is featured in the Feb. 6 edition of Science.
