Desalination roadmap seeks technological solutions to increase the nation's water supply

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Sandia National Laboratories researchers Pat Brady and Tom Hinkebein are putting the final touches on the updated Desalination and Water Purification Roadmap -- "Roadmap 2" -- that should result in more fresh water in parts of the world where potable water is scarce. The first roadmap identified overall goals and areas of desalination research and was submitted to Congress in 2003.

Raiders of the lost dimension

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

A team of scientists working at the National High Magnetic Field Laboratory's Pulsed Field Facility at Los Alamos has uncovered an intriguing phenomenon while studying magnetic waves in barium copper silicate, a 2,500-year-old pigment known as Han purple. The researchers discovered that when they exposed newly grown crystals of the pigment to very high magnetic fields at very low temperatures, it entered a rarely observed state of matter.

Address water scarcity, water quality issues around the world now, Sandia/CSIS report says

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Now is the time to address the devastating effects of increasing water scarcity and declining water quality around the world, according to a recently released white paper written jointly by Sandia National Laboratories and the Washington think tank Center for Strategic and International Studies (CSIS).

Repeatable low-breakdown voltage antifuses enabled through a Sandia-developed dielectric thin film

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Researchers at Sandia National Laboratories have developed an inexpensive, reliable and easy-to-manufacture class of dielectric films that have the capability of enabling programmable antifuses on integrated circuits (IC) at less cost and using easier-to-manufacture methods.

Laboratory scientists study soot in megacity pollution

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

A team of Los Alamos scientists recently returned from a month-long data-gathering trip to Mexico City as part of an international, multi-agency environmental science collaboration. The March campaign was designed to examine the chemical and physical transformations of gases and aerosols in the polluted outflow from the Mexico City metropolitan area.

Experiments examine hydrogen-production benefits of clean coal burning

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Experiments are underway at Sandia to optimize the combustion of coal to produce the most energy and the least possible pollution. Researchers say coal may remain competitive with other fuels after figuring in the possible benefits of sequestering carbon dioxide and generating both electricity and hydrogen in coal-fired power plants.

Avian flu modeled on supercomputer, explores vaccine and isolation options for thwarting a pandemic

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

Using supercomputers to respond to a potential national health emergency, scientists have developed a simulation model that makes stark predictions about the possible future course of an avian influenza pandemic, given today's environment of worldwide connectivity.

Sandia-designed supercomputer ranked world’s most efficient in two of six categories

DOE/Sandia National Laboratories
Peer-Reviewed Publication

A new series of measurements -- the next step in evolution of criteria to determine more accurately the efficiency of supercomputers -- has rated Sandia National Laboratories' Red Storm computer the best in the world in two of six new categories, and very high in two other important categories.
