Alaskan North Slope climate: hard data from a hard place

August 13, 2012 • Researchers examine clouds (from both sides now) and the structure of the atmosphere BARROW, Alaska — Sandia National Laboratories’ researcher Mark Ivey and I (science writer Neal Singer)  are standing on the tundra at an outpost of science at the northernmost point of the North American continent. We are five miles northeast...

Fiery research: Sandia computers model rocket fuel fires

July 31, 2012 • ALBUQUERQUE, N.M. — Walt Gill of Sandia National Laboratories’ Fire & Aerosol Sciences Department calls it a pancake — a disk more than a foot in diameter covered with what looks like the debris you’d scrape off a particularly messy barbecue grill. It’s actually a crunchy, baked-on mixture of aluminum,...

Predictions by climate models are flawed, says invited speaker at Sandia

July 25, 2012 •  ALBUQUERQUE, N.M. — Massachusetts Institute of Technology professor Richard Lindzen, a global warming skeptic, told about 70 Sandia researchers in June that too much is being made of climate change by researchers seeking government funding. He said their data and their methods did not support their claims. “Despite concerns over...

National workshop brings career development help to Sandia postdocs, student interns

July 17, 2012 • ALBUQUERQUE, N.M. — The American Chemical Society’s ACS on Campus is bringing career development workshops for scientists and engineers to Sandia National Laboratories’ postdoctoral fellows and interns, only the second time the program has come to a national laboratory. ACS on Campus will kick off the evening of July 19...

Small worlds come into focus with new Sandia microscope

June 11, 2012 • ALBUQUERQUE, N.M. — Paul Kotula recently told a colleague that Sandia’s new aberration-corrected scanning transmission electron microscope (AC-STEM) was like a Lamborghini with James Bond features.  The $3.2 million FEI Titan G2 8200 is 50 to 100 times better than what came before, both in resolution and the time it...

Sandia Labs’ unique approach to materials allows temperature-stable circuits

May 31, 2012 • ALBUQUERQUE, N.M — Sandia National Laboratories researcher Steve Dai jokes that his approach to creating materials whose properties won’t degenerate during temperature swings is a lot like cooking — mixing ingredients and fusing them together in an oven. Sandia has developed a unique materials approach to multilayered, ceramic-based, 3-D microelectronics...

Sandia Labs technology used in Fukushima cleanup

May 29, 2012 • ALBUQUERQUE, N.M. — A Sandia National Laboratories technology has been used to remove radioactive material from more than 43 million gallons of contaminated wastewater at Japan’s damaged Fukushima Daiichi nuclear power plant. Sandia researchers had worked around the clock following the March 2011 disaster to show the technology worked in...

New model of geological strata may aid oil extraction, water recovery and Earth history studies

May 23, 2012 • ALBUQUERQUE, N.M. — A Sandia modeling study contradicts a long-held belief of geologists that pore sizes and chemical compositions are uniform throughout a given strata, which are horizontal slices of sedimentary rock. By understanding the variety of pore sizes and spatial patterns in strata, geologists can help achieve more production from...

Sandia paper on flat-panel displays is one of Applied Physics Letters’ 50 greatest hits

May 7, 2012 • ALBUQUERQUE, NM — A paper by Sandia National Laboratories researchers with implications for early flat panel televisions is one of the 50 most cited papers from the prestigious journal Applied Physics Letters in the last 50 years, according to a listing made public by that journal. The 1996 paper shows...

Miniature Sandia sensors may advance climate studies

April 10, 2012 • ALBUQUERQUE, N.M. — An air sampler the size of an ear plug is expected to cheaply and easily collect atmospheric samples to improve computer climate models. “We now have an inexpensive tool for collecting pristine vapor samples in the field,” said Sandia National Laboratories researcher Ron Manginell, lead author of...

Sandia National Laboratories researchers find energy storage “solutions” in MetILs

February 17, 2012 • ALBUQUERQUE, N.M. – Sandia researchers have developed a new family of liquid salt electrolytes, known as MetILs, that could lead to batteries able to cost-effectively store three times more energy than today’s batteries. The research, published in Dalton Transactions, might lead to devices that can help economically and reliably incorporate...

Anthrax-killing foam proves effective in meth lab cleanup

February 16, 2012 • Sandia’s decontamination foam, developed more than a decade ago and used to decontaminate federal office buildings and mailrooms during the 2001 anthrax attacks, is now being used to decontaminate illegal methamphetamine labs. Mark Tucker, a chemical engineer in Sandia’s Chemical & Biological Systems Dept. and co-creator of the original decontamination...

Sandia chemists find new material to remove radioactive gas from spent nuclear fuel

January 23, 2012 • ALBUQUERQUE, N.M. – Research by a team of Sandia chemists could impact worldwide efforts to produce clean, safe nuclear energy and reduce radioactive waste. The Sandia researchers have used metal-organic frameworks (MOFs) to capture and remove volatile radioactive gas from spent nuclear fuel. “This is one of the first attempts to...

Sandia researchers, UK partners publish groundbreaking work on Criegee intermediates in Science magazine

January 13, 2012 • LIVERMORE, Calif. — In a breakthrough paper (full text/PDF) published in this week’s issue of Science magazine, researchers from Sandia’s Combustion Research Facility, the University of Manchester and Bristol University report direct measurements of reactions of a gas-phase Criegee intermediate using photoionization mass spectrometry.
