Brookhaven Lab Breaks Ground for New Nanocenter

The U.S. Department of Energy’s Brookhaven National Laboratory held a
groundbreaking ceremony today for the Center for Functional
Nanomaterials (CFN). The CFN will provide researchers with advanced
probes and the ability to use new fabrication techniques to study
materials at nanoscale dimensions – typically, billionths of a meter,
or 1,000 times smaller than a human hair. These materials have
different chemical and physical properties than bulk materials and
could form the basis of new technologies.
The CFN – one of five
Nanoscale Science Research Centers to be built at DOE national
laboratories – was designed by HDR Architecture, Inc., of Alexandria,
Virginia, and is being constructed by E. W. Howell Co., Inc., of
Woodbury, New York. The 94,500-square-foot state-of-the-art
laboratory/office facility is expected to attract an estimated 300
researchers from the Northeast annually.
Brookhaven employees and distinguished guests, including local
Congressman Tim Bishop and Dr. Patricia Dehmer, Associate Director for
the U.S. Department of Energy’s Office of Basic Energy Sciences,
attended the ceremony against a backdrop of heavy equipment at the CFN
location in the center of Brookhaven’s 5,300-acre site.
“The Center for Functional Nanomaterials will be at the forefront
of research that is expected to lead to new technologies, such as
faster computers,
new communications devices, improved solar energy and new energy
alternatives,” Congressman Bishop said. “Long Island is fortunate to
have this center here. Everyone reaps benefits when the best minds and
the best technology merge to explore the frontiers of science.”
DOE’s Office of Basic Energy Sciences is funding the $81-million
CFN project. The contemporary building, which has a metal and glass
exterior, will cost $38 million to build, while specialized equipment,
such as electron microscopy facilities and lithography-based
fabrication facilities, and engineering and project management will
account for the balance of the budget. The facility, which will occupy
nine square acres and will accommodate 150 people, will be considered
“green,” or energy efficient and environmentally friendly, based on the
U.S. Green Building Council’s rating system. Construction is expected
to be completed by March 2007, and experiments are due to begin shortly
after that date.
The overarching research goal of the CFN is to help solve energy
problems in the U.S. by exploring materials that use energy more
efficiently and by researching practical alternatives to fossil fuels,
such as hydrogen-based energy sources and improved, economical solar
energy systems.
Under the energy banner, CFN studies will focus on three key areas:
nanocatalysis, the acceleration of chemical reactions using
nanostructures; biological and soft nanomaterials, such as polymers and
liquid crystals, in which specialized design is expected to lead to new
functions; and electronic nanomaterials that exhibit unprecedented
control of electrons, which are expected to lead to new communication
and energy-control devices.

SLOW LIGHT AT ROOM TEMPERATURE (Score: 1)
by vlad on Tuesday, October 04, 2005 @ 23:05:32 UTC
(User Info | Send a Message) http://www.zpenergy.com | RESEARCHERS USE LASER AMPLIFIER TO SLOW LIGHT AT ROOM TEMPERATURE, October 04
Researchers at the University of California, Berkeley, have made a dramatic
advance in their quest to slow light down for applications in speedier
communication networks.
The research team, led by Connie J. Chang-Hasnain, UC
Berkeley professor of electrical engineering and computer sciences, has created
a device that uses a laser amplifier to slow the speed of light more than one
million-fold. The researchers clocked the speed of light at 245 meters per
second, or three-quarters the speed of sound in air. Moreover, the team did this
at room temperature.
