Catalysis: The science behind sustainable energy
About 60 percent of the things we wear or use are produced by processes that depend on catalysis. Catalysts are substances that modify chemical reaction rates and remain unchanged afterward. Catalyst technologies affect nearly all areas of the chemical and petroleum industries with an economic impact estimated at more than $10 trillion per year worldwide. Now more than ever, innovative and improved catalyst technologies are in demand for new energy production processes to ease the United States' dependence on imported resources.

Fish-friendly solutions
Although turbines have generated power at hydroelectric dams for many years, not much is known about how water flowing through the turbines may harm fish. In efforts to design more "fish-friendly" turbines, Pacific Northwest National Laboratory researchers conducted laboratory experiments to examine the relationship between water velocities within the turbine chambers and injuries to fish.

"Smart" energy devices + real-time pricing = increased options for consumers
About 200 volunteers in the Pacific Northwest are testing equipment that is expected to make the power grid more reliable while offsetting huge investments in new transmission and distribution equipment. Pacific Northwest National Laboratory recently launched the Pacific Northwest GridWiseTM Testbed Demonstration, a regional initiative to test and speed adoption of new smart grid technologies that can make the power grid more resilient and efficient.

WSU and PNNL break ground on new facility
Washington State University and Pacific Northwest National Laboratory broke ground April 13, 2006, on the Bioproducts, Sciences, and Engineering Laboratory. The BSEL is a $24-million joint effort between WSU and PNNL. Located on the WSU Tri-Cities campus, researchers will use the laboratory to develop processes for converting low-value agricultural byproducts and residues into value-added chemicals for products like plastics, solvents, fibers, pharmaceuticals and fuel additives.

Managing the Soviet legacy
An intact nuclear weapon is stolen and detonated. A terrorist group somehow steals, purchases, or produces fissile material and fabricates a crude bomb, called an improvised nuclear device, which the group threatens to detonate if its demands are not met.

Science for security
Since the terrorist attacks of September 11, 2001, national security has become a priority mission of the Department of Energy. This mission, which in addition to public safety focuses on the protection of America's economic and energy security assets, is supported by an increasingly robust program of technological innovation.

Research shows ventilated auto seats improve fuel economy, comfort
The US Department of Energy's National Renewable Energy Laboratory (NREL) has demonstrated that ventilated automotive seats not only can improve passenger comfort but also a vehicle's fuel economy. That's because ventilated seats keep drivers and passengers cooler, so they need less air conditioning to be comfortable.

Brookhaven scientists aid in homeland security field study
If an industrial accident or a terrorist act released dangerous contaminants into the atmosphere in New York City, the city's first responders would have to decide quickly whether people should shelter in place or be evacuated, and what evacuation routes should be considered. In the future they will be aided in making those decisions by information gathered during the New York City Urban Dispersion Program field studies, conducted in the city's urban canyons in March and August of 2005.

Mimicking nature's crystalline structures
Scientists and engineers have long envied nature's ability to design crystalline structures whose properties are often superior to those of similar synthetic materials. Through a process called biomineralization, proteins orchestrate the growth processes of many natural minerals into designs that confer exceptional properties.

NOvA: A neutrino appearance experiment
Deep in the woods of Minnesota, close to the Canadian border, particle physicists hope to construct the next neutrino experiment on a secluded piece of land, fit for studying a lightweight particle that was, itself, once ignored.

eco-science
Stepping onto the site of a physics laboratory, you might expect to see enormous accelerators, ultra-powerful supercomputers, or scientists in lab coats racing between experiments. At one lab, however, what you will actually see are goats. At Lawrence Berkeley National Laboratory in Berkeley, California, goats roam through the hills, push over fences, and climb trees.

The search for extra dimensions
Although we now think of the universe as three bulky, nearly-flat dimensions, we might soon discover that the fabric of space-time consists of many more dimensions than we ever dreamed.

Spallation Neutron Source amazing science facts
The New Year is bringing the science community a grand present: The Spallation Neutron Source at Oak Ridge National Laboratory. On schedule for completion in 2006, the Department of Energy's new science facility will provide researchers with the world's most powerful and most advanced tool for analyzing a host of materials with neutrons.

The sky's the limit
Earth's climate is noticeably changing over time. Glaciers are smaller, droughts last longer, and extreme weather events like fires, floods and hurricanes occur more frequently. PNNL researchers involved in the Atmospheric Radiation Measurement (ARM) Program are working to understand these phenomena through improved cloud representations in the computer models that simulate changes in the earth's climate.

Cyber security
Do you worry about the security of your credit card when you buy something over the Internet? Or when you pay your bills electronically? What about business trade secrets communicated by email from engineering to manufacturing staff or sensitive data stored on local hard drives? Computer scientists at Pacific Northwest National Laboratory are using a systems approach combined with a multidisciplinary team of experts to address cyber security issues such as these.

NVAC: Visualizing a safer homeland
September 11, 2001 forever changed how Americans view national security. The responsibility for protecting citizens from future attacks has fallen on government shoulders in an increasingly discontented world. One way the Department of Homeland Security has responded is with new visual analytic technologies that transform volumes of documents, emails, images, videos and voice recordings into interactive visuals.

Environmental biomarkers provide early warning of disease
Outbreaks of Avian flu or "bird flu" during the past several years have disrupted the poultry industry. More ominous is that the virus spreads to humans. The ability to identify this disease early on may help prevent epidemics that wreak havoc on a country's economy and take lives. Now, researchers at Pacific Northwest National Laboratory, through the multi-year Environmental Biomarkers Initiative (EBI), are developing new techniques and tools for identifying these early warning signals also known as environmental biomarkers.

A limitless potential
Researchers believe carbon nanotubes may prove to be the most promising nanoscale materials for multifunctional applications. These hollow tubes of carbon often have multiple, concentric layers of carbon sheets, like rings of a tree. A single-wall carbon nanotube (SWNT)--one sheet of carbon atoms rolled into a tube--has special properties resulting from a structure much more like that of a one-dimensional molecule than bulk graphite.
