Solar cells give ray of hope to Swiss scientists
The future of solar energy has been given a boost thanks to a new type
of solar cell developed by the Federal Institute of Technology in
Lausanne. The so-called nanocristalline solar cells have been shown to
be much cheaper and just as effective as the silicon cells which have
been used to make solar energy until now.

Nanotechnology: Public debate takes off
Two new reports look at the social and environmental implications of
nanotechnology, indicating a growing polarisation of the public
debate. Nanotechnology and nanoscience are high up on the EU's
research agenda, granting this area a specific budget of over 700
million euro in its 6th Framework Programme for Research and
Technological Development (6th FP, 2002-2004). However, there is no
debate yet at EU level on the opportunities and dangers of this new
technology, nor on the societal and environmental implications.

Wired Ready-to-Wear
Electronic fabric is showing up on museum walls and in art galleries.
But you can't start wearing it yet. As this ScienCentral News video
reports, smart fashions will need nanotechnology, the science of
making molecules do useful things, to be ready to wear.

'Twinning' phenomenon found in nanocrystalline aluminum
Discovery could help in development of new materials for microscopic
machines
Using a powerful electron microscope to view atomic-level details,
Johns Hopkins researchers have discovered a "twinning" phenomenon in a
nanocrystalline form of aluminum that was plastically deformed during
lab experiments. The finding will help scientists better predict the
mechanical behavior and reliability of new types of specially
fabricated metals. The research results, an important advance in the
understanding of metallic nanomaterials, were published in a recent
issue of the journal Science. At the microscopic level, most metals
are made up of tiny crystallites, or grains. Through careful lab
processing, however, scientists in recent years have begun to produced
nanocrystalline forms of metals in which the individual grains are
much smaller. These nanocrystalline forms are prized because they are
much stronger and harder than their commercial-grade counterparts.
Although they are costly to produce in large quantities, these
nanomaterials can be used to make critical components for tiny
machines called microelectromechanical systems, often referred to as
MEMS, or even smaller nanoelectromechanical systems, NEMS.

Natural nanostructures
M. Kawamura, N. Paul, V. Cherepanov, B. Voigtlander
Physical Review Letters (to appear)
Nanometer-sized electronic structures are highly desirable for the
future miniaturization of electronic devices. Recent experiments have
shown that it is possible to grow silicon and germanium nanowires with
a thickness of one atomic layer by using the natural self-organization
of atoms at surfaces. More complex structures, such as nanorings, are
also possible, and researchers hope to be able to one day use these
methods to build complex semiconductor devices.

The mind of an American specialist in nanotechnology
The word "nanogram" means one billionth of a gram. Nanotechnology
penetrates within nanograms, and rearranges atoms. If the atoms in
coal are rearranged, it becomes diamond (a mediaeval alchemist's
dream). Such are its civilian uses. As for its military uses, Mark
Gubrud of the University of Maryland has posted on a website his
18-page paper, "Nanotechnology and International Security," for the
Fifth Foresight Conference on Molecular Nanotechnology.

Titania nanotubes make supersensitive hydrogen sensors
Titania nanotubes are 1500 times better than the next best material
for sensing hydrogen and may be one of the first examples of materials
properties changing dramatically when crossing the border between real
world sizes and nanoscopic dimensions, according to a Penn State
materials scientist. "Historically, we have viewed sensor technology
and enhancements from the point of view of surface area," says Dr.
Craig A. Grimes, associate professor of electrical engineering and
materials science and engineering. "The principle in play in titania
nanotubes is not surface area, but connectivity of the tiny tubes and
we see an incredible change in electric resistance." Hydrogen entering
an array of titania nanotubes flows around all the surfaces, but it
also splits into individually charged atoms and permeates the surface
of the nanotubes. These hydrogen ions provide electrons for
conductivity. The change in conductance signals that hydrogen, above
the background level, is present.

Wescon 2003: Building the Future One Atom at a Time
Wescon Launches Nanotech Pavilion at North American Show
SAN FRANCISCO, July 30 /PRNewswire/ -- The science of the very small
is simply too big to ignore. For the first time, Wescon, the oldest
and longest-running conference for and by engineers, is adding
nanotechology to the engineering tool-box. The IEEE San Francisco and
Los Angeles councils have decided to co-locate IEEE-Nano 2003 pavilion
with Wescon North America at San Francisco's Moscone Center from
August 12 - 14. For more information about the conference, please
visit http://www.wescon.com. With the U.S Government earmarking $710
million dollars for nanotech research this year and with a potential
of two million new jobs in the field over the next seven years, Wescon
organizers decided that now is the time to showcase technology that
will lead to more powerful computers, applications, products and
markets.

Chip senses trace DNA
Handheld detectors could one day allow you to monitor your body for
cancer, your water for toxic chemicals, and your food for nasty
bacteria. Making these devices means developing inexpensive
electronics that are capable of detecting trace amounts of substances.
One candidate is a chip containing DNA-tipped carbon nanotubes.

Shirts That Stop Bullets
What if you could wear lightweight armor that kept you warm and let
you phone home? Nanotechnologists have come up with a super strong,
flexible fiber that can conduct heat and electricity. It could be made
into a modern version of chain mail, the heavy metal mesh worn by
medieval knights. If woven from the new fiber, modern chain mail could
be light as a cotton shirt, but bulletproof.

UK - New Report from University of Sheffield - The Social and Economic
Challenges of Nanotechnology
Nanotechnology is an emerging range of technologies in which medicine
and engineering meet physics and chemistry. Nanotechnology supporters
claim that the machines and materials it may produce will mean faster
computers, less pollution and cheaper energy, and longer and healthier
lives. Critics, however from Prince Charles to Jurassic Park author
Michael Crichton fear that nanomachines could run amok and turn the
surface of the Earth into an uninhabitable morass. Environmentalists
also question the safety of nanoparticles. The debate, like that on
genetically modified food, is noisy but often uninformative. Before
the technology has even emerged, the debate has largely become
polarised into utopian and dystopian visions. In a report published
today [Download - PDF 1.4Mb] (28th July 2003), a team at the
University of Sheffield funded by the Economic and Social Research
Council investigates the scientific reality behind nanotechnology, and
looks at the hopes and the fears that it raises and provides a sober
assessment of the possibilities that will help both sides of the
debate.

Standards to help manufacturers measure micromachine properties
When a car collides with another car, a tiny device called an
accelerometer detects the change in motion and sets off an air bag, an
innovation that has saved many lives. The accelerometer is one of the
most common uses of microelectromechanical systems (MEMS), but
scientists and engineers also are starting to use them in devices
ranging from angioplasty pressure sensors and pacemakers to optical
disk drives. MEMS, also known as micromachines, are a relatively new
technology that uses existing microelectronics manufacturing methods
to create complex machines with micrometer feature sizes. MEMS devices
represent a rapidly growing component of the semiconductor industry.

Overused, Misused Nano Becoming Pervasive Prefix
NEW YORK (Reuters) - Even though nanotechnology is still in its
infancy, the nano prefix is quickly growing into one of the most
over-used and misused phrases in the English language. More than 1
million entries containing the word "nano" turned up using Google, the
Internet search engine, while Hoovers.com lists dozens of companies
with nano in the name.

Don't hate me because I'm nano-beautiful
A recent New York Post story about nanotech in cosmetics had me
thinking about beauty. Small Times reported last year that
nanomaterials had been used in cosmetics for years. So now, with
renewed debate surrounding what is not known about nanoparticles, the
fact that nanoscale zinc oxide and titanium dioxide are used in some
brands of cosmetics and sunscreen are continuously juxtaposed with
news reports about the controversy. In this cursed and wonderful age
of Google, whose spawn is quick access to information but ad nauseaum
repetition of often questionable factoids, the L'Oreal lore has
circled the globe more than a few times, ripped from its original
context. For more nanobeauty, go to Howard Lovy's NanoBot.

CRN Offers Qualified Endorsement of Greenpeace Nanotech Report
NEW YORK The Center for Responsible Nanotechnology [profile] today
announced its conditional support of the Greenpeace report, "Future
technologies, today's choices", about the risks, benefits, and current
status of nanotechnology. "We've heard from extremists on both sides,"
said Mike Treder, Executive Director of CRN. "Now it's time for sober
discussion and serious research. This report clearly is a step
forward." Chris Phoenix, CRN's Director of Research, agreed. "We have
to accept that some nanomaterials and nanotechnologies may be
hazardous. But we use hazardous materials all the time, safely and
beneficially. We'll need to study and decide case by case. We need
information and common sense, not panic or denial."
CRN has primarily focused on the benefits and dangers of molecular
nanotechnology (MNT), which promises someday to allow flexible
atomic-scale manufacture of breakthrough products. "Many have argued,
loudly but weakly, that MNT is impossible," said Treder. "The
Greenpeace report acknowledges difficulties, but opens the door to
consideration of the possibilities."
CRN believes that serious discussion of the consequences of MNT is
necessary now. "Progress may happen sooner than people think," said
Phoenix. "Once the engineers start working on it, the field could take
off very quickly, and its impact could be massive."
