'Nanotractor' studies micro-scale friction
Interest in the development of MEMS (microelectromechanical systems) has grown steadily during the past decade. These tiny devices, now used in such applications as auto airbag systems, inkjet printers, and display units, are attractive because they take up little space and require little or no assembly. They also are cheap to produce in batch quantities because they are made with a technology that is already mature -- the microlithography used to make silicon chips.

Progress through computation
If we continue to burn fossil fuels for energy at the current rate, they will last only another few hundred years. In the context of civilization, the fossil fuel era is drawing to a close. In addition, it would be wise to reduce our combustion of oil, gas, and coal because the process produces pollutants that are bad for our health and carbon dioxide that could change our climate in undesirable ways. One possible future source of electricity for the world is fusion energy.

Glimpses of global warming
As greenhouse gases accumulate in the atmosphere, many questions arise concerning how fast and in what ways Earth's environment will change. For example, in the United States, will increased emissions of carbon dioxide from coal combustion in the 21 st century make the Southeast wetter or drier over the next 100 years? Will changes in temperature and moisture conditions make certain U.S. regions more vulnerable to insect-borne diseases?

New research facility holds promise for nation's energy future
Ground was broken July 27 on a new facility at the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL), designed to increase collaboration among researchers and speed the time it takes for new technologies to move from the laboratory bench to commercial manufacturing.

Nuclear energy to go: A self-contained, portable reactor
Nuclear energy supplies 20 percent of the electricity used in the U.S. and 16 percent of that used throughout the world. But as the global use of nuclear energy grows, so do concerns about the vulnerability of nuclear plants and fuel materials to misuse or attacks by terrorists.

Going to extremes
Little is known about the chemistry that produces minerals in the deep regions of Earth or that creates the ammonia oceans of the outer planets and moons. What is known is that an element's fundamental properties--its optical, structural, electrical, and magnetic characteristics--can completely change when it is put under extreme conditions.

Helping water managers ensure clean and reliable supplies
MOST Americans take cheap and plentiful supplies of pure drinking water for granted. Some even consider it to be an inalienable right. However, clean water sources, especially pristine underground aquifers, are being consumed at an increasing rate, and contaminants and changing patterns in rain and snowfall are threatening the adequacy of supplies.

Yucca mountain- Pursuing a license
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.

Seeing the universe in a grain of dust
Imagine traveling halfway to Jupiter--3.2 billion kilometers--for a small handful of comet dust. That's the mission for the National Aeronautics and Space Administration's (NASA's) Stardust spacecraft launched on February 7, 1999. This past January, Stardust flew by Comet Wild 2's nucleus and through a halo of gases and dust at the comet's head, collecting cometary dust particles released from the surface just hours before.

Nuclear plants may be clean hydrogen source
For more than 100 years, visionaries have periodically espoused the dream of an economy driven by hydrogen - an efficient fuel that emits only water when burned.

Argonne tests, creates fuel cells to power the future
Fuel cells are a key component of the nation's plan for a secure energy future. Fuel cells convert hydrogen gas into electricity and water. Since hydrogen can be produced from a variety of domestic resources, researchers are seeking cost-efficient ways to use it to meet the nation's growing energy needs and reduce the nation's oil reliance.

Recovering fuel from waste
The nation's permanent nuclear waste repository could be used more efficiently than currently planned, according to ORNL's Emory Collins. He and his colleagues believe it makes sense for the repository to take mainly nuclear fission products, or 5% of the wastes, and turn away the bulk of the waste--spent nuclear fuel. The usable uranium and plutonium in this material could be extracted, chemically treated, and recycled as mixed-oxide (MOX) fuel for nuclear reactors.

Fabricating fuels
Over the past decade, increased public pressure to provide more electricity, reduce air pollution, and slow the rate of global warming has led many Americans to revisit the potential of nuclear power to meet anticipated demands for more energy. The Department of Energy and others in the scientific community are interested in adapting the gas-cooled reactor for use both in producing hydrogen for fuel cells to power cars and buildings and in supplying electricity competitively.
