Researchers Take a Big Step Forward in
Making Smaller Circuits
|
PHILADELPHIA
-- Physicists at the University of
Pennsylvania have overcome a major hurdle
in the race to create nanotube-based electronics. In
an article in the August issue of the journal
Nature Materials, available online now, the
researchers describe their method of using
nanotubes tiny tubes entirely composed of
carbon atoms -- to create a functional electronic
circuit. Their method creates circuits
by dipping semiconductor chips into liquid
suspensions of carbon nanotubes, rather than
growing the nanotubes directly on the circuit.
"Given
their amazing electric properties, nanotubes
have been a subject of keen interest for creating
such things as chemical sensors, flexible electronics
and high-speed, high-device-density microprocessors
for computing," said Alan T. Johnson, associate
professor in Penn's Department of Physics and
Astronomy. "The problem is that
the properties we like best about nanotubes
their size and physical properties also make
them very difficult to manipulate."...read

Debate : Global
Special
Report - NanoGeoPolitics:
ETC Group Surveys the Political Landscape
|
Fearful
that nanotech may face the same fate as biotech
crops, the G8 used their Gleneagles summit
to promote "new technologies" (including nanotech
and biotech) as the magic bullet to "make poverty
history" and to neutralize global warming.
By hinting at the availability of billions
for science capacity-building in the South,
the North hopes to make allies of South governments,
scientists, development NGOs, and environmentalists.
Meanwhile, the real action is behind the scenes
where various government/industry and scientific
institutions are rushing to negotiate what
the EU hopes will become a nanotech "code of
conduct"(but, in light of US opposition may
turn into a "framework of shared principles")
and lay down the global standards, regulations,
and market modus operandi for the greatest
industrial revolution society has ever (not)
seen coming. Social policy is being replaced
by science policy. In this special report,

Single
molecule is in driver's seat of molecular
machine
|
EVANSTON,
Ill. --- While the human body has plenty of specialized
molecular motors and machines powering the mechanical
work necessary for cells to function properly,
scientists themselves face many hurdles as they
try to create their own molecular machines in
the laboratory.
The
downsides of conventional molecular machines
are that they are driven as an ensemble,
by external light or chemistry, for example,
and they are big -- made up of many molecules.
These factors make these machines difficult
to control.
In
a theoretical paper published in the journal
Physical Review Letters, two Northwestern
University chemists have shown how molecular
machines can be driven individually (relying
on only one molecule) by applying an electric
current that creates an internal energy source.
"People
envision using molecular machines for computing
techniques, sensors, bioengineering and solar
cells, for example," said Tamar Seideman, professor

research opens door to new hydrogen production
method

Researchers
in Italy have developed a new technique for
producing hydrogen, and for purifying polluted

The technique involves the release of oxygen from cerium oxide,
a pale yellow-white powder used in ceramics and to polish glass.
'Ceria-based materials are oxygen buffers, materials that allow
[one] to efficiently store or release oxygen, thus favouring
a high catalytic activity and inducing a set of chemical reactions
which would otherwise require higher pressures and temperatures,'
says Friedrich Esch from the TASC INFM-CNR laboratory. The
findings could therefore make an important contribution towards

Buyers and Sellers Stuck in a Pricing Stalemate

NEW
YORK, /PRNewswire/ -- Are high prices a barrier

a remarkable disconnect, 75% of large corporations
that buy components based on nanotechnology believe
that they hold the pricing power in deals, while
70% of sellers think that in fact they have the
upper hand. The result: Deals languish while
corporate buyers use delay tactics on overeager
sellers.
"Pricing
is cited by 45% of corporate buyers as a major
challenge that often impedes nanotech deals.
Buyers lament that sellers frequently pay attention
only to the cost of their own components, missing
the big-picture view," said Lux Research Senior
Analyst David Lackner. "Only 15% of sellers,
however, see pricing as a major problem. They

The findings are a significant step in developing

They appear in the July 22, 2005 edition of

Relying
on photons or atoms to carry information from
one place to another, network security relies
on a method known as quantum cryptographic
key distribution. In this method, the two information-carrying
particles, photonic qubits or atomic qubits,

recognition plays an important role in biological

However, markedly strong bonds are occasionally

that antigens can have multiple binding sites,
to which multiple antigen-binding sites in the
antibody can bind at the same time. This once again
demonstrates that the whole can be more than the

|
A
portable, versatile and low-cost molecular detection
tool being developed by a team of Computer code-makers
may soon get the upper hand on code-breakers
thanks to a new quantum cryptography method designed
at the University of Toronto. Quantum cryptography
uses particles of light to share secret encryption
keys relayed through fibre-optic communications.
A
paper published in the June 16 issue of the
Physical Review Letter demonstrates how senders
can vary the intensity of laser light particles
(photons) used in fibre-optic communications
to create decoys that catch eavesdropping attempts. "To
exchange secret communication, the sender and
the recipient first have to exchange a random
series of 0s and 1s - known as the encryption
key - through a sequence of photons,"...read

Portable
molecular detection tool to revolutionise
medical diagnosis
|

A
portable, versatile and low-cost molecular
detection tool being developed by a team of
European researchers promises to revolutionise
the diagnosis of diseases such as cancer and
open up new applications in sectors as diverse
as environmental protection, chemical analysis
and food safety.
Working in the field of micro- and nano-technologies, the IST
programme-funded BioFinger project is due to begin testing
its state-of-the-art system over the summer amid expectations
for a commercial product to be available on the market within
two to three years.
“What we are creating is a generic, highly precise and highly versatile tool
to detect and analyse molecules in the blood and other fluids using nano and
micro cantilevers,” explains project coordinator Joan Bausells at the Consejo
Superior de Investigaciones Cientificas in Spain...read

New
infrared tool measures silicon
wafer thickness
|

In
the last few years, semiconductor circuit features
have shrunk to sub-100 nanometer (nm) dimensions,
while the size of the thin silicon wafers that
these circuits are constructed on has grown
from 200 millimeters (mm) to 300 mm (about
12 inches). The payoff is a higher yield of
finished devices from fewer wafers.
The
tough part, however, is to make wafers substantially
larger while simultaneously meeting higher
quality control specifications. The optics
and materials for "printing" nanoscale circuit
lines require that the wafers used are perfectly
flat and of uniform thickness. To help the
semiconductor industry meet its 2010 quality
control roadmap goals, researchers at the National
Institute of Standards and Technology (NIST)
recently developed a...read

The
Evolution of Frankenfoods?

Avoid "dead
water," the website advises, or else risk cardiovascular
disease. According to Nanotechnology Limited, dead
water is distilled or purified water that lacks
minerals the body needs. The Chinese company claims
that its product " nano
water ," currently available in Hong Kong supermarkets,
is not only pure but has enhanced properties that
fight inflammation, cancer and even aging itself.
Thanks to a "nanometer high-energy water activator," this
superwater has smaller molecule clusters that enable
more direct absorption by the body.
Whether these claims are true
or not -- scientists that I directed to the website
pronounced it "hilarious" and "completely bogus" while
company officials declined comment -- "nano water" is
piggybacking on one of the most heralded scientific
advances of our generation...read

Safety
fears over 'nano' anti-ageing cosmetics
|
THE
cosmetics giant L'Oréal is marketing a range
of skin treatments containing tiny “nano” particles,
despite concerns about their possible long-term
effects on the human body.
The products, which include
anti-wrinkle creams such as Revitalift, are said
to be absorbed deeper into the skin than more
traditional treatments because of the far smaller
size of their particles.
However,
the cosmetic use of nanotechnology, originally
employed in man-made fibres and pharmaceuticals,
has led to calls from both the Royal
Society and the Food and Drug Administration
(FDA) in America for a comprehensive
programme of research.
They aim to discover what

The
diameter of an ion beam is only 20 nm and its aiming
accuracy is 60 nm. "Single Nanoscale structures
with unique properties are a treasure trove for
developing novel nanoelectronic devices of the
next generation.
However,
understanding the properties of such nanoscale
structures is harder than creating the nanostructures.
Prof. Aono, who has been creating various nanostructures
of interest by manipulating atoms and molecules
using a probe tip of a scanning tunneling microscope
(STM), has expanded his research field to the
property measurement of nanostructures.......read
