Nanotech funding bill in the wings. On Tuesday, the Oregon Democrat is
planning to introduce a bill and convene a hearing to spur the development
of nanotechnology by spending more government money on early-stage research.
A summary of the bill seen by CNET News.com says it will establish a
"National Nanotechnology Research Program" to coordinate federal efforts in
the area and balance research objectives with ethical and societal concerns.
It will spend about $446 million, with a portion of that to come from
existing money located elsewhere in the federal budget. Last year, the
government spent $463 on nanotechnology. (Cnet 9/16/02)

Nanotubes could reduce CO2 emissions.  A team led by scientists at Carnegie
Mellon University said Monday that carbon nanotubes, which are straw-like
structures with walls a single atom thick, could filter gases much more
quickly than current systems. The atoms of carbon nanotubes are arranged so
that they offer practically no friction to passing gas molecules, said David
Sholl, a professor of chemical engineering at Carnegie Mellon. Such smooth
surfaces mean the tubes theoretically can transport gas through a membrane
at rates that are orders of magnitude greater than current microporous
substances used in gas separation, Sholl told United Press International.

Researchers Create Rare, Large Symmetrical Crystals Accident Leads to
Important Discovery. Researchers at Rensselaer Polytechnic Institute in
Troy, N.Y., have created large symmetrical crystals that rarely occur in
nature. These crystals could be harder than conventional engineering
materials. The accidental discovery was made during attempts to make
superconducting nanostructures with a simple technique used to create carbon

New computer system solves problems by tricking computers. A Virginia Tech
researcher has come up with a computer technology he calls 'Weaves' that
allows a programmer to use a code in any programming language and convert it
to a form similar to object-oriented programming. Weaves technology is used
to create a virtual world that tricks the software into thinking it is in
the real world. (Eurekalert 9/16/02)

Nimble Nanoswitch May Win Info Relay Race. Nanosize devices may be getting
their own ultra-small version of a component that few electronic gadgets can
function without: the switch. We have performed a theoretical analysis of a
carbon nanotube-based nanoelectromechanical switch," Swedish researchers
Tomas Nord, Susanne Viefers and Jari Kinaret revealed in a new paper. The
publication provides the first-ever blueprint for a nanorelay made from
microscopic carbon tubules -- a switching device that may one day prove
critical to nanotechnology. (Yahoo 9/13/02)

Samsung Dives Into the Nano Pool. Chipmaker Samsung Monday said it is
shifting its business strategy of its Memory Business Division by shrinking
the size of some of its semiconductors to the nanometer (define) level. The
South Korea-based company, whose semiconductor division is located in San
Jose, California, introduced a state-of-the-art 90-nanometer process
technology along with the successful pilot production of a 2Gbit NAND Flash
memory device using the 90-nanometer design. (SiliconValley internet.com

Nanotechnology expected to extend Moore's Law. Moore's Law will get a new
lease on life through this decade because of nanotechnology, the Intel
Developers Forum was told on Thursday. Sunlin Chou, senior vice president
and head of Intel's Technology and Manufacturing group, said new materials
and chip structures possible with nanotechnology will continue the doubling
of transistor count on die every 24 months that Moore postulated decades
ago. "The people who think Moore's Law will end assume that materials and
structures won't change. They are constantly changing and will keep Moore's
Law going for a lot longer," he said.  (EE Times 9/13/02)

Massachusetts bested California in a high-tech state-by-state comparison
released today by an economic think tank, findings that may reflect changing
dynamics among small tech's leading regions. Although the analysis by the
Milken Institute doesn't focus on small tech specifically, certain
categories used in the comprehensive analysis are particularly relevant to
micron and nanoscale technologies and their potential to boost state
economies. (Small Times 9/17/02)

Nano-Welding Creates Tiny Junctions. Researchers have discovered how to weld
together single-walled carbon nanotubes, pure carbon cylinders with
remarkable electronic properties. The discovery could pave the way for
controlled fabrication of molecular circuits and nanotube networks. Pulickel
Ajayan, professor of materials science at Rensselaer Polytechnic Institute
in Troy, N.Y., and his colleagues in Germany, Mexico, the U.K., and Belgium
used irradiation and heat to form the welded junctions. This is the first
time single-walled nanotubes have been welded together, although
multi-walled nanotubes with junctions previously have been created using
growth techniques. The electrical properties of single-walled nanotubes
surpass those of multi-walled tubes, which is why so many researchers have
been anxious to try this experiment, said Ajayan. (RPI 9/16/02)

The Right Stuff for Super Spaceships. Tomorrow's spacecraft will be built
using advanced materials with mind-boggling properties. What I'm really
looking for," you say to the salesman, "is a car that goes at least 10,000
miles between fill-ups, repairs itself automatically, cruises at 500 mph,
and weighs only a few hundred pounds." As he stands there wide-eyed, you
add, "Oh yeah, and I can only spend about a quarter of what these other cars
cost." Impossible? Before you answer, consider how a rancher from 200 years
ago might have reacted if a man had asked to buy a horse that could run 100
mph for hours on end, carry his entire family and all their luggage, and
sing his favorite songs to him all the while! Today we call them minivans.
Revolutions in technology--like the Industrial Revolution that replaced
horses with cars--can make what seems impossible today commonplace tomorrow.
Such a revolution is happening right now. Three of the fastest-growing
sciences of our day--biotech, nanotech, and information technology--are
converging to give scientists unprecedented control of matter on the
molecular scale. Emerging from this intellectual gold-rush is a new class of
materials with astounding properties that sound more at home in a science
fiction novel than on the laboratory workbench. -streaming audio- (Science

Nanotech's grand challenge: energy self-sufficiency, says von Ehr.
"Nanotechnology needs a 'grand challenge' project, and energy
self-sufficiency is one that would pay huge benefits to both the USA and the
world," says James R. von Ehr II, President & CEO of Zyvex Corp. He
presented this idea at the recent White House Economic Forum, which brought
together leaders from various sectors to discuss the fundamentals of the
economy and the President's agenda to increase economic growth for the
future. (KurzweilAI.net 9/11/02)

Hyperion Catalysis International is not like most other nanotechnology
companies. First, it's old, at least by nano standards. The Boston-area
company celebrated its 20th anniversary this summer. Second, it downplays
its nano heritage, or at least does not participate in the hype. Hyperion
has been making what it calls Fibrils, a form of multiwall carbon nanotubes,
since the 1980s - years before the scientific community acknowledged the
existence of carbon nanotubes. Staff members are more likely to attend a
conference on plastics than any of the numerous nanotech gatherings that
proliferated recently.

Lightning Rods for Nanoelectronics. Electrostatic discharges threaten to
halt further shrinking and acceleration of electronic devices in the future.
On a dry winter day, walking on a new carpet can generate a whopping
35,000-volt discharge. We are not harmed by this high voltage, because the
amount of charge that flows is puny. Still, it is large enough to destroy
sensitive micro-electronic components. Researchers have come up with clever
ways to prevent such damage. But as circuits get smaller, they become more
sensitive to electrostatic discharge (ESD) and the old tricks no longer
work. Can we continue to find new ways to prevent electrostatic damage and
thereby maintain the pace of innovation? -5 pages-

Scientists at the Lawrence Berkeley National Laboratory (Berkeley Lab) have
produced the first ever action movies starring individual water molecules on
a metal surface. The ending was a surprise even to the producers. Working
with a unique scanning tunneling microscope (STM), a team led by Miquel
Salmeron, a physicist with Berkeley Lab's Materials Sciences Division,
cooled the surface of a single crystal of palladium, a good catalyst for
reactions involving hydrogen and water, to a temperature of about 40 Kelvins
(-233 degrees Celsius) in an ultrahigh vacuum. Water molecules were then
introduced onto this surface and their motion was tracked with the STM. As
expected from previous studies, single molecules migrated across the surface
to aggregate into clusters of two (dimers), three (trimers), four
(tetramers) five (pentamers) and six (hexamers). The surprise came when the
scientists were able to watch the molecules as they moved. -Movie

Nanoporous polymer stamps out glare. Scientists at the Massachusetts
Institute of Technology, US, have developed a nanoporous polymer film that
acts as an antireflection coating. What's more, manufacturing the film is
relatively environmentally friendly and the pores are reversibly
erasable...The researchers made the films by applying an aqueous treatment
to multilayers of poly(allylamine hydrochloride)/poly(acrylic acid)
(PAH/PAA). By carefully controlling the pH during the process, they gave the
films a nanoporous structure. With further treatment, pores could be removed
or reintroduced. (Nanotechweb (9/12/02)
