Los Alamos researchers are using a proton accelerator to speed up potential circuit failure, battering circuits in a single hour with hundreds or thousands of years of the harmful neutrons created by cosmic rays. Aviation, computer and related companies, along NASA, are putting circuits through the rigors of the neutron testbed, which can generate essentially the entire neutron spectrum produced naturally by cosmic rays, but with neutrons a million times more intense than in nature.

Sandia National Laboratories scientists, engineers and technicians are performing critical experiments deep in the volcanic heart of Nevada's Yucca Mountain to provide information that will assist in a key decision as to whether to license the remote site as a permanent repository for these radioactive wastes. Our feature story looks at Sandia's role in the 20-year project.

Weighing less than 30 pounds, Sandia National Laboratories' miniSAR (synthetic aperture radar) will be onefourth the weight and one-tenth the volume of conventional SARs that now fly on larger unmanned aerial vehicles (UAVs). It is the latest design produced by Sandia in a history that involves more than 20 years of related research and development.

Our current agricultural food safety and security programs have provided the citizens of the U.S. the safest food production system the world has ever seen. But these programs were not designed to identify or respond to intentional acts of bioterrorism using either conventional or unconventional biological agents to contaminate our food or food processing/distribution system.

Building on more than 10 years of research and development, Sandia engineers have created a radar tag sensor that can be mounted on military vehicles and is recognizable to an attack aircraft as a "friendly."

In a series of tests conducted at Kansas State University on Bovine coronavirus (BCV) -- the internationally accepted surrogate for the Severe Acute Respiratory Syndrome (SARS) coronavirus -- Sandia versions of its DF- 200 formulation fully inactivated samples in one minute or less.

A new type of polymer electrolyte membrane (PEM) is being developed by researchers at the Department of Energy's Sandia National Laboratories to help bring the goal of a micro fuel cell closer to realization using diverse fuels like glucose, methanol, and hydrogen.

In his State of the Union address last year, President Bush proclaimed, "our scientists and engineers will overcome obstacles to taking these cars from laboratory to showroom so that the first car driven by a child born today could be powered by hydrogen, and pollution-free." Stepping up to that challenge are researchers at Sandia National Laboratories in California, which has been selected by the U.S. Department of Energy to lead a virtual Center of Excellence for the development of reversible metal hydrides materials.

In this week's journal Science, researchers at Sandia National Laboratories and the University of New Mexico describe a simple, commercially feasible method for self-assembling nanocrystals into robust orderly arrangements, like soup cans on a shelf or bricks in a wall or stopping nanocrystals from clumping.

Researchers at the at the National Nuclear Security Administration's Sandia National Laboratories have developed a new "inchworm" actuator instrument that provides detailed information about friction at the microscale.
