      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 Universit├Ąt
      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)

      '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)

      The State of Nanotechnology: Coming soon: nanoelectronics for infotech and

      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
