Self-powered devices possible, says Texas A&M researcher
Imagine a self-powering cell phone that never needs to be charged because it
converts sound waves produced by the user into the energy it needs to keep
running. It's not as far-fetched as it may seem thanks to the recent work of
Tahir Cagin, a professor in the Artie McFerrin Department of Chemical
Engineering at Texas A&M University. 12/2/08

Titania nanotubes create potentially efficient
solar cells
Penn State | EurekAlert!
A solar cell, made of titania nanotubes and natural dye, may be the answer to
making solar electricity production cost-effective, according to a Penn State

MIT researchers fired up about battery
alternative
Massachusetts Institute of Technology | EurekAlert!
Just about everything that runs on batteries -- flashlights, cell phones,
electric cars, missile-guidance systems -- would be improved with a better
energy supply. But traditional batteries haven't progressed far beyond the basic
design developed by Alessandro Volta in the 19th century. Until now. Work at
MIT's Laboratory for Electromagnetic and Electronic Systems holds out the
promise of the first technologically significant and economically viable
alternative to conventional batteries in more than 200 years. 2/7/2006

Adding nanotubes makes ordinary materials absorb
vibration
Rensselaer Polytechnic Institute | EurekAlert!
A new study suggests that integrating nanotubes into traditional materials
dramatically improves their ability to reduce vibration, especially at high
temperatures. The findings could pave the way for a new class of materials with
a multitude of applications, from high-performance parts for spacecraft and
automobile engines, to golf clubs that don't sting and stereo speakers that
don't buzz. 2/7/2006

Turbulence yields secrets to 73-year-old
experiment
University of Illinois at Urbana-Champaign | EurekAlert!
A simple but groundbreaking experiment performed more than 70 years ago finally
has been explained by scientists at the University of Illinois at
Urbana-Champaign. The solution sheds new light on fluid turbulence -- the last
major unsolved problem in classical physics. 1/30/2006

New Doubts Are Cast on Einstein's
Cosmological Constant
Dennis Overbye | New York Times
An astronomer said the force known as dark energy was not constant, as Albert
Einstein would have predicted, but was growing more violent.

Stricter Nanotechnology Laws Are Urged
Rick Weiss | RedOrbit News
An independent report being released this morning concludes that current U.S.
laws and regulations cannot adequately protect the public against the risks of
nanotechnology -- the rapidly growing science of making invisibly small
particles and molecular devices.
Unless existing laws are modified or a new one is crafted, the report warns, the
immense promise of the field -- predicted to be a trillion-dollar industry by
2015 -- may be short-circuited by either a disaster or an economically damaging
crisis of public confidence.
"There is a chance to still do this right and learn from previous mistakes,"
said study author J. Clarence Davies, an environmental policy analyst who played
major roles in the Johnson, Nixon and first Bush administrations and is now with
Resources for the Future, a nonpartisan think tank on environmental and energy
issues. 1/11/2006
