Pacific Northwest blazing big trail in small world
Last month's Micro Nano Breakthrough Conference in Portland brought together an amalgamation of national and international technology experts, with organizers hoping to convince them of a large future in the Pacific Northwest for tiny technology.

'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.

'Nanotools' - Self-assembling durable nanocrystal arrays
A wish list for nanotechnologists would likely include a simple, inexpensive means of self-assembling nanocrystals into robust, orderly arrangements, like soup cans on a shelf or bricks in a wall, each separated from the next by an insulating layer of silicon dioxide.

Fine-tuning carbon nanotubes
Since their discovery in the 1990s, carbon nanotubes have ensnared the imagination of chemists. Among them are researchers at Pacific Northwest National Laboratory who are putting these fine filaments--ten-thousand times smaller than a hair--to work as biosensors and improving the way carbon nanotubes can be chemically customized to form the basis for a wide variety of devices.

Nanoparticles may mean longer life for enzymes
The biochemical world's workaholic is the enzyme. Enzymes are molecules in cells that lead short, active and brutal lives. They restlessly catalyze their neighbors, cleaving and assembling proteins and metabolizing compounds. After a few hours of furious activity, they are what chemists call "destabilized," or spent.

Thin films enable next-generation displays
You've finished working on your computer and you're ready to call it a day. Instead of logging off and folding the screen down over a laptop keyboard, imagine rolling up the computer screen and stashing it in your bag. Roll-up computer screens and other flexible light-emitting displays that conform to almost any shape or surface may one day be realities thanks to a team of scientists at Pacific Northwest National Laboratory.

Supercritical fluids—making nanoparticles easy
It's not a liquid. It's not a gas. It's a supercritical fluid. Although it looks like a liquid, it has unique properties that allow scientists to work with it in ways they can't with liquids. Researchers at Pacific Northwest National Laboratory are using supercritical fluids as solvents in a process that creates nanoparticles.

Soil's a natural for storing CO2
In a field outside Charleston, S.C., PNNL's Jim Amonette and his colleagues from the U.S. Forest Service and Oak Ridge National Laboratory have planted 72 pots with Sudan grass. They don't care much about the grass, however--it's the soil beneath that captures their attention.

PNNL co-leads Center for Chemical Hydrogen Storage
Pacific Northwest National Laboratory, along with Los Alamos National Laboratory in New Mexico, will lead a new national Center for Chemical Hydrogen Storage. The new center is a step toward a "hydrogen economy"--an economy based not on the fossil fuels we use today, but on clean, abundant hydrogen fuels. It is one of three Department of Energy "Centers of Excellence" aimed at enabling use of hydrogen-powered vehicles.

Rest easy—it's safe and secure
The desk is cleared, the computer is off, and the weekend lies ahead-hit the lights and you are out the door. Not fifteen minutes later you begin to question whether you locked the safe where you store your classified materials--sound familiar? Even the most diligent and security minded personnel have at some time experienced this absent-minded professor syndrome.

Reading, writing and nanoscience?
Pacific Northwest National Laboratory has opened its doors to scholars of nanoscience by hosting the new "Intensive Courses in Nanoscience and Nanotechnology." Billed as one of science's hottest and most rapidly evolving fields, nanoscience involves the study of materials and their properties at the molecular level.

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?

Uncovering secrets of living cells
Probing microbes to determine what they are made of and what drives them requires more than mass spectrometers, microarrays, and microscopes. Computational models run on supercomputers have been key contributors to our growing understanding of these single-cell organisms.

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.

Future space scientists train at Brookhaven Lab
As astronauts spend more time in space, scientists need to better understand the dangers space travelers face from deep-space radiation -- and how to best shield them against these risks. A new NASA Summer Student Program at the U.S. Department of Energy's Brookhaven National Laboratory will help provide a "pipeline" of researchers to tackle this challenge. The program begins June 1, 2004

Agricultural biosecurity taking on increased importance
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.
