Fuel cells transform cars

Fuel cells are similar to batteries; they convert chemical energy into electricity. However, unlike batteries, fuel cells use chemicals that are external to the fuel cell. The types of fuel cells LANL scientists develop convert hydrogen and oxygen (from air) into electricity and water.

The system utilizes a thin membrane and catalysts - often made of platinum - to electrochemically convert the hydrogen and oxygen into electricity. "Of course, environmentally we love fuel cells because hydrogen plus oxygen makes water," says Rod Borup, program manager for the Laboratory's fuel cell program in MPA-11, the Sensors and Electrochemical Devices Group.

As Dawn approaches Mars, scientists gear up for GRaND tests


NASA illustration of the Dawn spacecraft.

GRaND (the Gamma-Ray and Neutron Detector) was developed by Los Alamos National Laboratory, and key sensor components were manufactured by eV Products,

Eljen Technology, and Proteus, Inc. Planetary Science Institute is responsible for operating the instrument and analyzing data acquired during the post-launch, science phase of the mission.

Research highlights potential for improved solar cell efficiencies


LANL’s Victor Klimov

To evaluate the influence of photoionization, the Los Alamos researchers conducted back-to-back studies of static and stirred solutions of nanocrystals. Stirring removes charged nanocrystals from the measured region of the sample. Therefore, when crystals are subjected to light, the stirring eliminates the possibility that charged nanocrystals will absorb a second photon. Read the story here.










Offsite source group gathers up the bad stuff


Americium-241 sources, each roughly the size of the tip of a pen, are readied for storage at Los Alamos, part of a shipment that represents the 15,000th recovered source. LANL photo.

The chances of U.S. radioactive sources falling into the hands of risky characters were reduced again last year with the help of a small team of scavengers at Los Alamos National Laboratory.


The lab's Off-Site Source Recovery Project, under supervision of the National Nuclear Security Administration, recently passed an important domestic milestone for getting dangerous materials out of the way. See the whole recovery
story here.

Satellites crash, but only meteors burn this bright


Researchers photograph the Sept. 2008 controlled re-entry of the European Space Agency's “Jules Verne” spacecraft. NASA’s primary goal of the project was to study the spacecraft's re-entry and compare it to meteor fragmentation. NASA photo.

The meteor would have to have been as big as a pickup truck, and traveling somewhere between 15,000 and 40,000 miles per hour when it entered the atmosphere.


That's small time for a meteor -- astrophysicist David Palmer of the Los Alamos National Laboratory tells Popular Mechanics that such speeds are close to the minimum at which meteors enter Earth's atmosphere.
Meteors orbiting the sun at the opposite direction of Earth could enter our atmosphere at up to 150,000 miles per hour. See the recent daylight meteor here.










Out of the muck of Crim Dell


Working in early September at the upper end of Crim Dell, freshman researchers Kasi Hartman and Sam Harvey take samples of soil and muck.

A group of William & Mary freshmen has discovered what appears to be a previously unknown form of life.

Using state-of-the-art lab techniques, the William & Mary freshmen isolated phages and prepared the DNA of the samples for sequencing - or genetic blueprinting - at Los Alamos National Lab.

Preliminary results from Los Alamos indicate that one of the 10 phage samples sent from William and Mary is a novel strain, previously unrecorded. See the story here.

Secretary of Energy Steven Chu, New York Times photo


The Energy Department is involved with efforts as varied as developing nuclear weapons and sequencing the human genome.

Steven Chu, the new secretary of energy said the department's nuclear weapons program, which the White House is considering moving to the Defense Department, should be more tightly coupled to science in critical tasks like safeguarding nuclear materials and detecting nuclear proliferation. Read the story here.












Glaciology: From the front

See the story here.









Research highlights potential for improved solar cells


A team of Los Alamos researchers led by Victor Klimov has shown that carrier multiplication—when a photon creates multiple electrons—is a real phenomenon in tiny semiconductor crystals and not a false observation born of extraneous effects that mimic carrier multiplication.


The research, explained in a recent issue of Accounts of Chemical Research, shows the possibility of solar cells that create more than one unit of energy per photon. Get more details here.








LabStart spins out money-making tech

Distant explosions behaving strangely have created a buzz in the astronomical community and may resolve a cosmic case of mistaken identity. Two kinds of flaring stars, Anomolous X-Ray Pulsars and Soft Gamma Repeaters may actually be the same thing.


"It's like learning the giant beasts who leap out of the ocean and splash down on the surface are the same as the ones you have heard singing in the depths," said David Palmer, a Los Alamos astrophysicist who develops software for detecting gamma-ray bursts in the universe.

Scientists at Los Alamos National Laboratory have successfully tested a liquid explosive detection system that may eventually have many security applications around the country.

Machines ready for an operational environment remains a few years away, but the technology is promising to quickly detect liquid explosives within a few years. He says, "Los Alamos has done an outstanding job in a relatively short period of time," says Stephen Surko, Program Manager for at the Department of Homeland Security’s Science & Technology Directorate. See the DHS press release here.






Cosmology researcher to speak on 'dark' universe


Most of the universe remains mysterious to scientists and researchers everywhere. More than 90 percent of the universe is "dark," composed of dark energy and dark matter observed only by their gravitational interaction with both light and "normal" matter.

Understanding the nature of dark energy and matter is one of the most significant challenges in science -- one that researcher Salman Habib and his team at the Los Alamos National Laboratory in New Mexico are working to overcome. See the NASA press release here.









Stimulus package could speed LANL cleanup


There are some differences with special significance locally in the two versions of the stimulus package that is coming together in Washington.

The House passed an $816 million version of the measure on Wednesday, containing $500 million for nuclear waste cleanup, one of the most obvious sources of extra funds at legacy nuclear weapons sites, like Los Alamos, which has struggled with funding shortages in recent years. See the Los Alamos Monitor for more.









Latest issue of 1663 magazine posted online


This edition looks at the “X-Games” of contemporary science, the proposed Yucca Mountain repository, and a technology under development to create a new way for diabetics to conveniently test their blood sugar levels—and much more.

Link Why is the publication called 1663? During World War II, all that the outside world knew of Los Alamos and its top-secret laboratory was the mailing address -- P.O. Box 1663, Santa Fe, New Mexico. That box number, still part of our address, symbolizes our historic role in the nation’s service. See 1663 here.
