Team observes real-time charging of a lithium-air battery
May 13, 2013 9:07 am | by David L. Chandler, MIT News Office | News | CommentsOne of the most promising new kinds of battery to power electric cars is called a lithium-air battery. But progress has been slow. Researchers have used transmission electron microscope (TEM) imaging to observe, at a molecular level, what goes on during a reaction called oxygen evolution as lithium-air batteries charge; this reaction is thought to be a bottleneck limiting further improvements to these batteries.
Fertilizer that fizzles in a homemade bomb could save lives around the world
April 23, 2013 8:24 am | News | CommentsA Sandia engineer who trained U.S. soldiers to avoid improvised explosive devices (IEDs) has developed a fertilizer that helps plants grow but can’t detonate a bomb. It’s an alternative to ammonium nitrate, an agricultural staple that is also the raw ingredient in most of the IEDs in Afghanistan. Sandia has decided not to patent or license the formula, but to make it freely available in hopes of saving lives.

"Zombie" replica cells may outperform live ones as catalysts, conductors
February 7, 2013 9:11 am | News | Comments“Zombie” mammalian cells that may function better after they die have been created by researchers at Sandia National Laboratories and the University of New Mexico (UNM). The simple technique coats a cell with a silica solution to form a near-perfect replica of its structure. The process may simplify a wide variety of commercial fabrication processes from the nano- to macroscale.
Airborne pods seek to trace nuclear bomb’s origins
January 10, 2013 9:11 am | News | CommentsIf a nuclear device were to unexpectedly detonate anywhere on Earth, the ensuing effort to find out who made the weapon probably would be led by aircraft rapidly collecting airborne radioactive particles for analysis. Relatively inexpensive UAVs—equipped with radiation sensors and specialized debris-samplers—could fly right down the throat of telltale radiation over a broad range of altitudes without exposing a human crew to hazards. A Sandia National Laboratories-developed airborne particulate-collection system demonstrated those kinds of capabilities.
Engineering alternative fuel with cyanobacteria
January 7, 2013 12:06 pm | News | CommentsSandia National Laboratories Truman Fellow Anne Ruffing has engineered two strains of cyanobacteria to produce free fatty acids, a precursor to liquid fuels, but she has also found that the process cuts the bacteria’s production potential.
Sandia Lab building solar test centers across U.S.
December 24, 2012 12:17 pm | by The Associated Press | News | CommentsOne of the National Security Administration's three national laboratories is building regional testing centers around the U.S. to field-test hardware for solar companies before their multimillion-dollar solar systems are installed in buildings.
Detecting tunnels using seismic waves not as simple as it sounds
December 10, 2012 1:09 pm | News | CommentsTunnels are often used to smuggle people and illicit goods between the border of the U.S. and Mexico. Researchers have attempted to use seismic waves to find these shallow tunnels, but current methods often miss them because of what is called the “halo effect”, in which fracturing and other geological anomalies create diffuse boundaries that hide open areas. A two-year study has shed light on this phenomenon and may lead to better results.
Researchers use shock tube for insight into physics early in blasts
November 20, 2012 10:58 am | News | CommentsSandia National Laboratories' multiphase shock tube began with a hallway conversation that led to what engineer Justin Wagner describes as the only shock tube in the world that can look a how shock waves interact with dense particle fields. The machine is considered multiphase because it can study shock wave propagation through a mixture of gas and solid particles.

Sandia shows why common explosive sometimes fails
September 21, 2012 5:05 am | News | CommentsThe explosive PETN has been around for a century and is used by everyone from miners to the military, but it took new research by Sandia National Laboratories to begin to discover key mechanisms behind what causes it to fail at small scales. By developing a novel technique based on physical vapor deposition to create samples with varying thickness, the researchers were able to study detonation behavior at the sub-millimeter scale and to determine that PETN detonation fails at a thickness roughly the width of human hair.
