<DIV><FONT face=Arial size=2>A V6 Engine for the Nano-Age. The world of the very
small is about to receive a very powerful engine. Berkeley Lab scientists have
created the world's smallest electric motor that may someday power nanoscale
devices that walk, crawl, swim, and fly. Although it is too early too determine
what the motor will propel — perhaps probes that deliver disease-fighting drugs
inside the body or winging nanobots that sniff out explosives — it packs a big
kick in its tiny frame. The motor measures only 200 nanometers long (a nanometer
is one-billionth of a meter), but its power density is 100 million times greater
than that of a 225-horsepower V6 engine. It draws its enormous power from
surface tension, the same cohesive force between liquid molecules that allows
bubbles to form and insects to walk on water. (Berkeley Lab 5/13/05)<BR><A

A Penn State College of Medicine study shows for the first time in an animal
model that ceramide, a naturally occurring substance that prevents the growth of
cells, can be administered through the blood stream to target and kill cancer
cells. "Ceramide is the substance that accumulates in cancer tissues and helps
to kill cancer cells when patients undergo chemotherapy and radiation," said
Mark Kester, professor of pharmacology, Penn State College of Medicine, Penn
State Milton S. Hershey Medical Center. "By boosting the amount of ceramide
through an injection in the bloodstream, our study in mice suggests that we can
provide a stronger cancer-killing therapy without additional side effects." This
study, titled "Systemic Delivery of Liposomal Short-Chain Ceramide Limits Solid
Tumor Growth in Murine Models of Breast Adenocarcinoma," was published in the
May issue of Clinical Cancer Research, a journal of the American Association for
Cancer Research. (Penn State 5/24/05) <A

space flight missions, NASA must continually monitor air quality and toxicity
levels to ensure the health and safety of the crew," said Spacehab Chief
Operating Officer Michael Bain. But, he added, "developing, transporting and
installing large, complex detection and classification equipment in orbit is
extremely problematic."...The NASA/Spacehab project aims to further reduce the

Spacehab has enlisted the help of Zyvex, a company that specializes in

<DIV><FONT face=Arial size=2>Nanotech Finds Tumors Before Visible on MRI.
Biomedical engineers have used nanotechnology to find human melanoma tumors in
mice while the growths are still invisible to conventional magnetic resonance
imaging (MRI). Earlier detection can potentially increase the effectiveness of
treatment. This is especially true with melanoma, which begins as a highly
curable disorder, then progresses into an aggressive and deadly disease. A
second benefit of the approach is that the same nanoparticles used to find the
tumors could potentially deliver stronger doses of anti-cancer drugs directly to
the tumor site with fewer side effects. (ScienceBlog 5/19/05)<BR><A

<DIV><FONT face=Arial size=2>Nanotechnology Makes Packaging Intelligent, Smart
and Safe. According to a new market study developed by Helmut Kaiser Consultancy
nanotechnology has been significantly increasing its impact on the food and
beverage packaging industry during last three years. The sales of the
nano-related packaging products have been rising from US$ 150 million in 2002 to
$ 860 million in 2004 worldwide. Nonetheless, compared with the over $100
billion food and beverage packaging industry, the growth potential of the
nanopackaging is still enormous. It is predicted that nanotechnology will change
25% of the food packaging business in the next decade, that means a yearly over
$ 30 billion market. (nanotechwire.com 5/26/05) <A

<DIV><FONT face=Arial size=2>>From attograms to Daltons: Cornell NEMS device
detects the mass of a single DNA molecule. Some people are never satisfied.
First, nanotechnology researchers at Cornell University built a device so
sensitive it could detect the mass of a single bacterium--about 665 femtograms.
Then they built one that could sense the presence of a single virus -- about 1.5
femtograms. Now, with a refined technique, they have detected a single DNA
molecule, weighing in at 995,000 Daltons -- a shade more than 1 attogram -- and
can even count the number of DNA molecules attached to a single receptor by
noting the difference in mass. The devices, which fall in the class of
nanoelectromechanical systems (NEMS), could be made even more sensitive through
increased miniaturization, the researchers say. The technology, they suggest,
can be combined with microfluidics to perform genetic analysis of very small
samples of DNA, even the amount present in a single cell. <BR>(Cornell 5/18/05)

<DIV><FONT face=Arial size=2>Nanotechnology comes to the lead-free rescue. Like
it or not, lead-free requirements and RoHS compliance are impending realities.
While many companies have processes and products that meet these requirements
right now, there are many reasons to be concerned about the use of lead-free
solders. Conductive adhesives with nano-engineered fillers have shown some
promise toward addressing those concerns. Much of this work is being done in the
US by Professor C.P. Wong’s group at the Georgia Institute of Technology.

Although the US remains the world leader in nanotechnology research and

Initiative (NNI), must do more to address societal concerns and the potential
risks - both environmental and health - of this developing technology. (Cordis

<DIV><FONT face=Arial size=2>Nanotube water doesn't freeze — even at hundreds of
degrees below zero. A new form of water has been discovered by physicists in
Argonne's Intense Pulsed Neutron Source (IPNS) Division. Called nanotube water,
these molecules contain two hydrogen atoms and one oxygen atom but do not turn
into ice — even at temperatures near absolute zero. Instead, inside a single
wall tube of carbon atoms less than 2 nanometers, or 2 billionths of a meter
wide, the water forms an icy, inner wall of water molecules with a chain of
liquid-like water molecules flowing through the center. This occurs at 8
Kelvins, which is minus 445 Fahrenheit. As the temperature rises closer to room
temperature, the nanotube water gradually becomes liquid. (Argonne 5/13/05) <A

<DIV><FONT face=Arial size=2>Buckyballs batter bacteria. For the first time,
researchers have shown that aggregates of C60—better known as fullerenes or
buckyballs—can form nanosized, crystalline structures that inhibit the growth
and respiration of certain bacteria. In a paper recently posted to ES&T’s
Research ASAP website (eso48099n), researchers at the Georgia Institute of
Technology and Rice University have also found that these nanocrystals may be
more mobile in water than expected. Both results strengthen the argument that
nanoparticles have different properties than their bulk counterparts, but those
differences are not reflected in current procedures for safe handling.

introduce nanotechnology to the next generation of environmental managers as
well as to instill some environmental awareness into nanotechnology
professionals. "One of the key features of this book is that it could serve both

offers material not only to individuals with limited technical background but
also to those with extensive industrial experience. As such, it can be used as a
