Splitting Up Cooper Pairs Carbon nanotubes might be used to separate the
entangled electron pairs in superconductors. The usual way of separating a
pair from the pack is to force it to tunnel across an insulating barrier,
but getting the electrons to tunnel into a pair of metallic leads won't
break the pairs apart. The electronic structure of carbon nanotubes--sheets
of pure carbon rolled into thin, micron-long cylinders--offers just the
right incentive for Cooper pairs to split, according to Smitha Vishveshwara
and coworkers at the University of California, Santa Barbara (UCSB).

Applied Materials Introduces Advanced Patterning Film to Enable Sub-50nm
Transistor Gates. Applied Materials, Inc. introduces its new Advanced
Patterning Film(TM) (APF(TM)), an innovative, easily strippable CVD
(chemical vapor deposition) hardmask solution that enables chipmakers to
fabricate sub-50nm transistor gates and contact structures using standard
DUV lithography. The proprietary APF technology, which is deposited with the
company's industry-leading Producer system, combines an amorphous carbon
film with a thin DARC(TM) (dielectric anti-reflective coating) layer to
provide the low reflectivity and high etch selectivity required to achieve
superior CD (critical dimension) control in sub-100nm devices. (Business

Selective Nanofilters For Proteins, DNA. A new type of nanotechnology-based
filter that can separate out mixtures of biological molecules has been
developed by researchers at the University of California, Davis. The
technology could potentially be used, for example, to build small-scale
devices for research in genomics by sorting mixtures of different proteins
or DNA molecules. (Science Daily 7/5/02)

UF team thinking small for treatments. In designing treatments that may prot
ect the heart and other organs from the toxic effects of drug overdose,
researchers at the University of Florida are thinking small - infinitely
small. UF scientists in medicine, engineering and chemistry see "enormous
potential" in the medical applications of drug-binding molecules tiny enough
to travel through the body's smallest capillaries. Called
nanopharmaceuticals, these drug-uptake particles are 10,000 times smaller
than the diameter of a human hair or 700 times smaller than the diameter of
a human red blood cell. (Gainsvillesun 7/8/02)

Triple nanolayers combat wear and tear. Scientists from Iowa State
University, US, and the Korea Institute of Science and Technology have
designed thin trilayer surface coatings that have good wear stability. The
films could have applications in microelectromechanical systems (MEMS) and
microfluidic devices. (Nanotechweb 6/25/02)

We should look forward to the future. Science may bring new risks, but it is
alarmist to fear that we cannot make technological advance work to
humanity's advantage. Digital media, communications and computer
technologies are becoming part of the environment in which we conduct our
lives. In the decades to come, genetic technologies and nano-machines,
microscopic robots assembled from atoms may well migrate into our bodies.

Carbon nanotubes put X-rays in the picture. Researchers from the University
of North Carolina at Chapel Hill, US, and Applied Nanotechnologies, US, have
used carbon nanotubes as the basis of a cold-cathode X-ray device. The team
used its system to image a fish and a human hand. (Nanotechweb 7/3/02)

Nanotech leading to diagnoses by handheld. Everyone knows the agony of
waiting days for test results from the doctor's office. Technology will soon
change that. Though medical professionals are far from the day when a
spaceship doctor can wave a tri-corder to make an instant diagnosis, the
next best thing is in the works. It's a handheld device based on
nanoparticles, and it's being developed at Northwestern University's
Institute for Nanotechnology in collaboration with Nanosphere Inc. (

Small Wonders. Nanotech's biggest breakthroughs won't come overnight. But
they will come -- and when they do, they'll change everything from computers
and vaccines to airplanes and TVs. What's the real story? Simply this: What
is happening in nanotech is indeed revolutionary, but it's happening on a
level far removed from products and markets. It's happening on the level of
a fundamental understanding of how the universe operates at the scale of
atoms and molecules, where Mother Nature does some of her most clever work.
Some of the world's top scientists, in disciplines such as biology,
chemistry, and physics that are traditionally seen as separate, are focusing
on the field. With this will come an explosion of discovery, encouraged by
government funding -- $2 billion worldwide this year -- unseen since the
Apollo space program. (Business 2.0 July issue)

Did Bell Labs` Rising Nanotech Star Commit the Cardinal Sin of Science? An
investigation at Bell Labs into cutting edge research on molecular
transistors and carbon molecules called buckyballs has cast a cold shadow
over nanotechnology this summer. While the pall isn't nearly as chilling as
the cold fusion controversy in 1989, the issues at stake are substantial. In
late May, Bell Labs, a part of Lucent Technologies, assembled a panel of
five scientists to look into questions of scientific misconduct by one of
its leading researchers, Hendrik Schön. (Small Times 7/3/02)

The Next Wave. Forget all the futuristic hype about subatomic robots.
Nanotechnology is already here, and Burlington CEO George Henderson is using

Singapore Backs Nanotechnology Business. Singapore, with full support of its
government, started to accelerate promotion of the nanotechnology business.
In January 2002, the National University of Singapore Nanoscience &
Nanotechnology Initiative (NUSNNI) was established in the National
University of Singapore. NUSNNI is an interdisciplinary group composed of
faculty from the departments of electronic engineering, mechanical
engineering, material engineering, environmental engineering, chemistry,
physics, biology, mathematics, and others. (AsiaBisTech 7/1/02)

Racing toward a nanotechnology industry: Purdue facility to link scientists,
entrepreneurs. In an effort to make electronic products that cost less and
deliver more, researchers at Indiana's Purdue University have found a way to
coax molecules to grow into microelectronic circuit elements.The approach,
which scientists say is akin to the way genes direct the growth of living
tissue, places Purdue among the leaders in a race to devise ways to grow
ultratiny integrated circuits, molecule by molecule. Many believe that this
approach - or something similar - will be vital if the microelectronics
industry is to continue packing more elements onto a smaller space.

Unproven nanotechnology still a big money draw. Even the cynics acknowledge
that not all the talk about nanotechnology is hype. Government research
grants are up about 25 percent, from $464 million last year to $579 million
this year. If Congress approves, it will jump to $679 million next year.
Universities are buzzing with lab activity. And Hewlett-Packard Co., IBM
Corp. and Intel Corp. are among those investing big money and time in
nanotech research.

Judge will be asked to decide fate of Ted Williams' body. Ted Williams'
estate will ask a judge to decide if the baseball great's body should be
cremated or frozen, a move to try to resolve a family feud over the remains.
Al Cassidy, the executor of the estate, will file Williams' will in state
court on Tuesday or Wednesday and ask the judge to rule on the issue, John
Heer, a lawyer for Williams' oldest daughter, said Monday. (Boston Globe

Nanotechnology pushes cad over technology barriers. Are the limits to
computer technology growing or shrinking? Many commentators agree that
Moore's Law will likely plateau by 2020 or 2025, marking an end to the
theory of a relentless doubling of microchip power every 18 months. So what
comes next? Instead of looking inside a laboratory for answers, researchers
may find answers in the natural world around us, says Eric Drexler, an
author and nanotechnology proponent. Drexler spoke at COFES, a small trade
show whose organizers aim to spark discussions, as opposed to lectures.

U-M scientists to develop nanosensors for astronauts. Tiny devices will fit
inside cells; monitor signs of radiation damage or infection. Along with
space suits, freeze-dried food and barf bags, tomorrow's astronauts may
travel with nanomolecular devices inside their white blood cells to detect
early signs of damage from dangerous radiation or infection.
The National Aeronautics and Space Administration (NASA) is investing $2
million to develop this "Star Trek" technology at the University of Michigan
Medical School's Center for Biologic Nanotechnology. The three-year research
grant is the largest the Medical School has ever received from NASA,
according to James R. Baker, Jr., M.D., who will direct the project.
