5-Apr-2007 Science and Technology Facility is first LEED Platinum Federal Building
A research facility at the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory has been designated as one of the most energy efficient and environmentally friendly places to work in the United States by the U.S. Green Buildings Council under its Leadership in Energy and Environmental Design (LEED) Green Building program.
22-Mar-2007 Sailing for science
When most people think of an ocean
cruise, they think of buffets and relaxing
in deck chairs. For Pacific Northwest
National Laboratory researcher Philip
Long, an expedition cruise aboard the
Joint Oceanography Institutes Deep
Earth Sampling (JOIDES) Resolution
research vessel meant 12-hour workdays
examining ocean floor core samples for
22-Mar-2007 Carbon capture made easy
Gasification plants may be one
of the keys to a hydrogen economy,
if capture and sequestration of carbon
dioxide (CO2) becomes technically
and economically feasible. These plants
would transform fossil fuel feedstock,
including coal, biomass and municipal
wastes, into clean-burning hydrogen
gas where the only byproduct is water.
1-Dec-2006 Nuclear energy and the 21st century
The world is entering a period of renewed interest and
growth in nuclear energy, driven by rising oil prices, growing
demand for electricity, new passively safe plant designs, and
low emissions of greenhouse gases, which some governments
need to meet Kyoto Protocol standards. The Kyoto Protocol
assigns mandatory targets for reducing greenhouse gas
emissions to signatory nations.
29-Nov-2006 Moving grid operations from minutes to seconds
In the last century, the electric power grid has grown from a
system that served one square mile in New York into a highlycomplex
interconnected system that serves all of North America.
Initially, individual local systems would connect to each
other to share resources and increase reliability.
29-Nov-2006 Coal: An energy bridge to the future
For years, coal drove the transportation business in this country, and it may be poised for a comeback. A hundred years ago, steam engines burned tons of coal as they
pulled trains across the country. Now researchers are looking at converting that coal to liquid fuel to fill our gas tanks and move cars and trucks.
20-Nov-2006 Fuel cell prototypes exceed expectations
Fuel prices continue to rise. However, one solution -- fuel cells -- is gaining on that problem. The Solid State Energy Conversion Alliance (SECA) has achieved the first of a threepart goal: developing solid oxide fuel cell systems that reduce fuel cell production costs by a factor of ten.
17-Nov-2006 Technology improves food processing quality
Researchers at Pacific Northwest
National Laboratory have developed an
ultrasonic technology that could tell
food manufacturers if foreign objects
have fallen into their product long
before it reaches the consumer.
16-Nov-2006 Sometimes smaller is better
A research team from the Pacific Northwest National Laboratory, Oregon Health and Science University, University of Minnesota and the University of Idaho is studying the ability of nanoscale iron particles to reduce carbon tetrachloride, a common groundwater contaminant.
9-Nov-2006 US wind power industry tempers its 2006 forecast slightly
The American Wind Energy Association (AWEA) announced on October 24th that the U.S. wind energy industry remains on track to set a record for wind power installations this year, with U.S. wind generating capacity increasing by 2,750 megawatts (MW).
23-Oct-2006 DOE/EPA release top fuel economy lists for 2007 models
The U.S. Department of Energy (DOE) and the U.S. Environmental Protection Agency (EPA) today released the 2007 Fuel Economy Guide to help consumers make well-informed choices when purchasing new vehicles.
30-Jul-2006 Hypernuclei at Jefferson Lab
In 1827, Robert Brown observed that pollen grains floating in a drop of water jiggled constantly. The phenomenon became known as Brownian motion. Over 75 years later, Einstein proposed that the pollen grains were being jostled by the molecules of water. The impurity (pollen grains) Brown had added to the water allowed Einstein to deduce the presence of individual water molecules and describe at least one of their properties.
20-Jul-2006 Pocket-sized physics detector does big science
How do quarks and gluons, the elementary constituents of all matter, combine to form the protons and neutrons in the nucleus of the atom? This is a fundamental unsolved question in nuclear physics that researchers at Jefferson Lab are working to answer. The internal structure of the proton has been studied for several decades, and scientists have learned a great deal. However, much less is known about the structure of the neutron.
20-Jul-2006 Spin structures of protons and neutrons
Just as a top spins on a table, the tiny quarks inside protons and neutrons also
spin. Now a complex calculation
by theoretical nuclear physicists at Jefferson Lab has revealed that a quark's
spin may be altered by the surroundings
of the proton or neutron in which it resides. This surprising result, recently
published in the journal, Physical
Review Letters, may lead to new insights about how ordinary matter is constructed.
20-Jul-2006 On the leading edge
The Accelerator Division's Institute
for Superconducting Radiofrequency
(SRF) Science & Technology
is a world leader in SRF accelerator
technology research and design. Now
the newest idea out of the Institute
may revolutionize the way accelerating
cavities are produced -- making
the manufacturing process faster and
cheaper, while producing cavities that
could potentially outperform any other
niobium cavities ever tested.
20-Jul-2006 Big Bite does its stuff
Jefferson Lab's core mission is to
study the heart of ordinary matter:
the nucleus of the atom. Now Hall A
has a new magnet and detector system
designed to help physicists look
at the nucleus in a whole new light.
"BigBite" has debuted in its first
experiment at Jefferson Lab.
5-Jul-2006 G-Zero update
In research performed in Hall C,
nuclear physicists have found that
strange quarks do contribute to the
structure of the proton. This result
indicates that, just as previous experiments
have hinted, strange quarks
in the proton's quark-gluon sea contribute
to a proton's properties. The
result comes from work performed by
the G-Zero collaboration, an international
group of 108 physicists from
19 institutions, and was presented at a
Jefferson Lab physics seminar on June
29-Jun-2006 Lightweight materials pave the road for energy-efficient vehicles
In efforts to shorten the long road to fuel efficiency, researchers at Pacific Northwest National Laboratory are working to develop cost-effective, high-strength, lightweight materials that will reduce vehicle weight without compromising cost, performance or safety.
27-Jun-2006 "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.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
