Nanoscale Elevator Raises the Bar. Complex device demonstrates progress in 
designing and building molecular machines.  complex nanoscale machine that can 
shuttle molecules like a tiny elevator has been designed, built and operated. 
Developed by Italian and American researchers, the tiny, chemically driven 
machine consists of a platform with three rings, each of which is attached to 
the leg of a tripod-like structure. At just 2.5 nanometers high and 3.5 
nanometers in diameter, the elevator represents a big advance for the 
construction of molecular machines, experts say.

NEC claims carbon nanotube monopoly, offers licenses. NEC Corp. asserted 
Wednesday (March 3) that it owns essential patents on carbon nanotubes and, as a
result, all companies seeking to make or sell carbon nanotube materials must 
obtain licenses from NEC. At the same time NEC said it had granted Sumitomo 
Corp. a non-exclusive license to operate under the basic Japanese patents owned 
by NEC that cover carbon nanotubes. (EETimes 3/3/04) 

Solar-powered Molecular Motor Built. Could provide parts for nanoscale machines.
The first molecular motor has been created that runs on electricity or light. 
Developed by Frederick Hawthorne and colleagues from the University of 
California, Los Angeles, the tiny motor could power machines on a scale smaller 
than biological motors such as flagella. "Given the existence of biological 
motors, the interest of chemists in designing molecular motors stems from the 
challenge not only of making even smaller nanomachines that perform controllable
motion, but also of creating systems that can be powered with light or 
electrical energy, rather than depending on the delivery of ATP," say the 
researchers. (Betterhumans 3/18/04)

Single molecules pass doping test. Physicists in the US have moved a step closer
to controlling the electronic properties of individual molecules in a condensed
matter environment. Michael Crommie and colleagues at the University of 
California at Berkeley and the Lawrence Berkeley National Laboratory have 
demonstrated a new way to "dope" single carbon-60 molecules with potassium 
atoms. The team says its method is the molecular equivalent of the n-type doping
that is widely used in the semiconductor industry (R Yamachika et al. 2004 
Sciencexpress 1095069).

seat the next-generation of computer chips. (BusinessWire 3/22/04) 


Yarn spun from nanotubes. Tiny tubes may yield ultrastrong fibres. Scientists 
have spun long, rope-like fibres from nanotubes. Their environmentally friendly 
method could be tweaked to make high-strength threads for use in engineering. 
The long ropes could even lead to futuristic applications such as a space 
elevator. Alan Windle and colleagues at the University of Cambridge, UK, made 
their tiny twisted ropes by winding freshly made nanotubes onto spinning rods as
they came out of a furnace. The nanotubes are hollow strands of carbon just 30 
millionths of a millimetre or so wide - around 5,000 times thinner than a human 
hair. (Nature 3/12/04) http://www.nature.com/nsu/040308/040308-10.html

Max Planck researchers use nanotechnology to visualize cellular processes 
crucial for the development of new cancer drugs. With the help of semiconductor 
nanocrystals, researchers at the Max Planck Institute for Biophysical Chemistry 
in Goettingen, Germany, and their collaborators at the Universidad de Buenos 
Aires are now able to capture movies of signal transmission processes involved 
in the control of gene expression (Nature Biotechnology, February 2004 issue). 
This breakthrough is expected to speed up the development of new cancer-curing 
drugs. (MaxPlanck 3/5/04)


Triton's nanotechnology designed to take on tumors. CEO looks to raise $18M 
second round to get it to clinical trials. Samuel Straface is betting that 
nanotechnology originally designed to repair military vehicles can be 
successfully used for something far different: to kill cancer tumors. Straface 
is president and CEO of Triton BioSystems Inc. in Chelmsford, a 3-year-old 
biotechnology/medical device company hybrid. And he believes the company's 
system will essentially fry a tumor without significant side effects, ultimately
helping to treat patients in lieu of toxic chemotherapy or radiation. (Boston

Nanotech could be boon to our society, economy. Nanotechnology. What is it? How 
close is it? Why are so many smart people talking about it? If you're worried 
about the future of our economy, jobs, and the American way of life, spending a 
few minutes learning about nanotechnology will open your eyes to an astounding 
future -- a future worth saving and investing for! (ChicagoSun Times 3/18/04)

Evaporation leads to nanotube foams. Researchers at Rensselaer Polytechnic 
Institute, US, have made two-dimensional cellular nanotube foams by evaporating 
a liquid from an array of multiwalled carbon nanotubes. The foams could have 
applications as shock-absorbent structural reinforcements and elastic membranes.

Electricity controls nanocrystal shape. Wires, tubes and brushes make it 
possible to build and maintain the machines and devices we use on a daily basis.
Now, with help from a surprising source, these same building blocks can easily 
be created on a scale 10,000 times smaller than the period at the end of this 
sentence. Researchers at Argonne have figured out the basics of using 
electrochemistry to control the architecture of nanocrystals - small structures 
with dimensions in billionths of meters. Their findings, published in the March 
3 edition of the Journal of the American Chemical Society, provide a practical 
method of generating large quantities of architecture-controlled nanocrystals, 
such as superconductors, ferromagnets and noble metals. (Argonne 3/17/04) 

'Nano-Lightning' Could Be Harnessed to Cool Future Computers. Mechanical 
engineers at Purdue University are developing a new type of cooling technology 
for computers that uses a sort of nano-lightning to create tiny wind currents. 
The researchers have shown that the underlying concept for a "micro-scale 
ion-driven airflow" device is sound and have recently filed for a patent. "This 
is a groundbreaking idea," said Suresh Garimella, a professor of mechanical 
engineering at Purdue who is working on the device with Timothy Fisher, an 
associate professor of mechanical engineering, Daniel J. Schlitz , who recently 
earned a doctoral degree from Purdue, and doctoral student Vishal Singhal. 
Schlitz and Singhal have created Thorrn Micro Technologies Inc. to commercialize
the cooling system. Future computer chips will contain more circuitry and 
components, causing them to generate additional heat and requiring innovative 
cooling methods. Engineers are studying ways to improve cooling technologies, 
including systems that circulate liquids to draw heat from chips. Using a liquid
to cool electronic circuits, however, poses many challenges, and industry would
rather develop new cooling methods that use air, Garimella said. (Ascribe 


Playing with Nanoblocks. In CRN's construct of a desktop nanofactory, products 
are built by putting together combinations of predesigned nanoblocks. This is 
intended to maximize the latent innovation potential in the widespread 
distribution of low-cost (or free), albeit technically restricted nanofactories.
It also could prevent illicit, unwise, or malicious product development. 
Product design will be made simple by CAD (computer aided design) programs, so 
simple that a child can do it-and that's no exaggeration. New product prototypes
can be created, tested, and refined in a matter of hours instead of months. No 
special expertise is needed. Just imagination, curiosity, and the desire to 
create. (CRN 3/04) 

2003 Researcher of the Year. The industry's court artist chisels 'tetrapod' 
masterpiece to harness sun. Nanotech's own Michelangelo has an equally 
polysyllabic name: Alivisatos. Like the Renaissance sculptor, the modern-day 
chemist is a master of material and shape - except Alivisatos' materials are 
semiconductor nanocrystals, not marble or plaster, and his shapes are dots, rods
and pyramids. It's no surprise that his colleagues describe his nanocrystals as
"visually beautiful." But Alivisatos' ability to control the dimensions and 
shape of nanocrystals as they grow ensures that they are functional as well. One
form of his nanocrystals, called quantum dots, already is marketed as 
biological markers, while his nanorods are being tested in solar cells.

EU nanotechnology project to reconstruct human corneas using tissue engineering.
A new EU funded project is set to transform eye surgery and dramatically cut 
the number of experiments conducted on animals by reconstructing a human cornea 
in vitro. The 'Cornea Engineering' project is adopting a unique approach to 
corneal replacements - using tissue engineering to create a three dimensional 
human cornea. This is the first time that this feat will have been attempted in 
Europe, although similar research is being conducted in the US and Canada.

California Firm Pearlife's Products Offer Skin Care Based on Nanotechnology. 
Mention nanotechnology and some might envision the B2 Stealth Bomber. After all,
it is nanotechnology that allows the plane's protective shielding to deflect 
enemy radar so the craft can fly undetected, even at low altitudes. But an 
Industry-based company is using that same technology in the production of its 
skin care line. The PearLife Co.'s products -- including the firm's signature 
Fantastic O's Skin Care facial cream -- are designed not only for cosmetic 
purposes, but also for protection from radiation generated by computers, 
televisions and microwave ovens. (Smalltimes 3/04)

Nano What? Survey Shows Most People in the Dark. Most Britons have never heard 
of nanotechnology and have no idea what it is, according to a survey released on
Monday. But the majority of the 29 percent of people questioned in the poll who
were aware of it think the ultra-small scale technology will have a beneficial 
effect in the future. The survey was carried out by the Royal Society, an 
academy of leading scientists, and the Royal Academy of Engineering. ( Bizreport

'Nanograss' Turns Sticky to Slippery in an Instant. With possible applications 
in everything from microscopic plumbing to slick boat hulls to switches for 
optical networks, a new chameleonic material developed at Bell Labs sheds water 
droplets like a newly waxed sports car, but, at the flick of a switch, turns 
absorbent like a "quicker picker upper" paper towel. Depending on the chemical 
structure of a solid, water and other liquids either cling to it - making it wet
- or it repels them. Usually a surface is absorbent or repellent, but not both.
"What we're trying to do is make a surface which you can control on the fly," 
said Dr. Tom N. Krupenkin, a scientist at Lucent Technologies' Bell Labs who led
the research. "If you can change that on the fly, it opens up applications 
everywhere." (NYTimes 3/16/04)
