Shrink-Wrapped Nano-Beanpoles. Flexible insulating ligands twist around
rigid molecular wires. A new class of double-helical molecules has been
synthesized. The molecules consist of two platinum atoms bridged by a
rodlike chain of carbon atoms--along which electrons and charge can
flow--surrounded by diphosphine ligands bearing flexible carbon double
helices that insulate the rods. (Chemical & Engineering News 5/31/02)

The Perfect Rake/Nanoconstruction site. Imagine raking leaves in the yard
and finding that--instead of a random pile--the leaves form perfectly
ordered towers. In the 27 May print issue of PRL a team reports essentially
that effect at the atomic scale. To investigate the process of mechanical
wear, which affects both diesel engines and nanomachines, they carved a
microscopic trench and found that the accumulated atomic debris had
surprising order. The researchers also measured the energy that went into
vibrating the crystal surface and into ripping out atoms. (Physical Review

Scientists roll out molecular barrow. A team of French and German scientists
has designed a barrow made from a single molecule just 1.6 x 1.5 nm in size.
The work, carried out at CEMES-CNRS, France, and the Freie Universität
Berlin, Germany, is reported in the June issue of the journal
Nanotechnology. "The molecular barrow is the first step to understanding the
basic mechanical movements of a 'simple' molecule on a surface," Hao Tang of
CEMES told nanotechweb.org. "After the experimental validation of this
system, we will focus on building more complex molecular machines."

UCR scientists report a new organic bistable material. Scientists at the
Center for Nanoscale Science and Engineering at the University of
California, Riverside report in the 24 May 2002 issue of the journal Science
a new bistable material that is likely to be of enormous interest and
benefit to the electronic industry as well as to the computer storage
industry. The material, as yet without a popular name, simultaneously
exhibits bistability in three physical channels: optical, electrical, and
magnetic. (Eurekalert 5/23/02)

IBM says nanotube transistor beats silicon. The next generation of
semiconductors will be carbon-based if researchers at IBM's T.J. Watson
Research Center here have their way. IBM revealed details Monday (May 20)
about what it is calling "the world's best transistor," based on a single
carbon nanotube measuring 1.4-nanometers in diameter. Fabricated with
conventional MOSFET processing technology, IBM characterized both n-type and
p-type FETs using carbon nanotubes as the channel. (EETimes 5/23/02)

The U.S. Army Armament Research, Development and Engineering Center (ARDEC),
plans to start a Public Private Partnering (PPP) program to exploit the
dual- use benefits of Nanotechnology. Under this initiative a Manufacturing
Research, Development and Education (RDE) Center is being envisioned to
address anticipated challenges to field nanotechnolgy and nanostructured
materials with respect to their producibility, characterization and
transition to both existing and future munitions. A major objective of PPP
is to encourage and formulate partnerships with academia and small
businesses to establish joint programs on a variety of subjects related to
manufacturing science and technology of nanometal powders, advanced
energetics, advanced warheads/armament components, devices and dual use
applications. (eps.gov 5/6/02)

Nanotech's Teeny Tiny Truth. The Nanobiz Will Be Huge, Vcs Say. But Should
They Even Be In The Game? The drop-off was stomach-churning. In 2000,
venture capitalists poured $100 billion into startups. Last year, they
couldn't even reach $40 billion. So forgive them for latching onto nanotech
as the uptrend. Headlines like "NANOTECHNOLOGY WINS OVER MAINSTREAM VENTURE
CAPITALISTS" and "THE NEXT BIG THING IS VERY SMALL" are getting hard to
avoid. Nano conferences are weekly events, crowded with VCs amped up about
self-assembling machines and nanobots in your bloodstream. (Wired 6/02)

(More from Wired) Thinking Big About Nanotechnology. Nanobots,
molecular-scale robots that can clear clogged arteries or inspect and repair
microfractures on aircraft and pipelines, are likely to remain science
fiction for the foreseeable future. But materials that can shed dirt and
stains are already here, and they represent what may be the first real
revolution in technology since people first began chipping away at rocks.

A Thousand Dots Of Light. Inside a lab at Hayward, Calif.-based Quantum Dot,
a scientist named Marcel Bruchez is looking through his microscope at a
bunch of glowing dots. These nanometer-sized structures are called quantum
dots. They are an important advancement in our understanding of how genes
work. Bruchez is assigning colorful bar codes of these dots to various genes
within DNA--a process known as bead-based genotyping. His work will be
instrumental in allowing researchers to monitor reactions of cells to
certain drugs or viruses. (Forbes 5/29/02)

Spiral Semiconductors - Nanowires. Supramolecular organic structures as
templates for inorganic nano-objects Because of their special optical and
electronic properties, new nanostructures of inorganic materials are of
interest as building blocks for nanotechnological devices. A promising
starting point for the synthesis of such materials seems to be the use of
"templates" or molds made of organic molecules that arrange themselves into
highly organized nanostructures and guide the shape and size of inorganic
compounds. Researchers at Northwestern University in Evanston have now
impressively demonstrated the potential of this method: They have succeeded
in producing semiconducting nanospirals of cadmium sulfide. (Wiley 5/02)

Deep Vision. When walls become doors into virtual worlds. It was when he was
being measured for a new suit that Thomas A. DeFanti, a computer scientist
and photographer at the University of Illinois in Chicago, came up with a
new angle on virtual reality. DeFanti recalls looking at himself in the

'Nanotorus' nets giant magnetic moment. Carbon nanotubes bent into rings are
the latest nanostructures to display surprising properties, according to new
calculations. Shi-Yu Wu of the University of Louisville and colleagues found
that the magnetic moments of some metallic 'nanotori' were thousands of
times stronger when the rings had certain 'magic' radii. The researchers
believe that such unexpected properties could be explained by the unusual
behaviour of the electrons when they circulate in the ring-shaped
structures. (PhysicsWeb 5/22/02)

Physicist Hawking seeks to stop book. Stephen Hawking has asked the Federal
Trade Commission to stop publication of an upcoming book. The physicist
alleges in a complaint that "The Theory of Everything" will "constitute a
fraud on the public" because it simply repackages old material, including
Hawking's million-selling "A Brief History of Time." The complaint, filed

The State of Nanotechnology: Coming soon: nanoelectronics for infotech and
medicine.
Three years ago, when Rice University chemist James Tour pitched his
nanotechnology startup to investors, he had a hard time getting anyone to
listen-despite his track record as one of the world's most accomplished
experts in nanoscience. Today, Tour says those same investors are all ears.
"After working in this area for 13 years and having people say, 'That's pie
in the sky. It'll never work,' it's gratifying to see some validation from
the investment community," he says. (TechReview 6/02) There is nothing else
