A whole slew of nanotechnology news

In a departure from the usual format, here’s a roundup of nanotech news from the last two days of KurzweilAI.net’s e-newsletter. There’s so much here these bits are taken straight from the email.

Controlling the Size of
Nanoclusters: First Step in Making
New Catalysts
KurzweilAI.net July 10, 2008
*************************
Researchers from the U.S.
Department of Energy’s (DOE)
Brookhaven National Laboratory and
Stony Brook University have
developed a new instrument that
allows them to control the size of
nanoclusters — groups of 10 to 100
atoms — with atomic precision. The
device could allow for making
nanoclusters with predetermined
size, structure and…

*************************
Nanotubes Hold Promise for
Next-Generation Computing
Wired July 9, 2008
*************************
Two groups of researchers have
recently published papers
demonstrating advances in creating,
sorting and organizing carbon
nanotubes so they can be used in
electronics. Stanford electrical
engineers addressed the problem of
getting nanotubes straightened out
so they could be put to work in
chips, by growing the nanotubes on
crystalline quartz,…

*************************
Assembling Nanotubes
Technology Review July 10, 2008
*************************
Stanford University and Samsung
Advanced Institute of Technology
researchers have developed a new
method for sorting single-walled
carbon nanotubes by electronic type
and arranging them over a large
area; it could be useful for
manufacturing high-performance
displays and other electronic
devices. (Melburne LeMieux /
Stanford University)…

Nanotubes bring artificial
photosynthesis a step nearer
New Scientist news service July 11, 2008
*************************
Carbon nanotubes are the crucial
chemical ingredient that could make
artificial photosynthesis possible,
say Chinese researchers. Artificial
photosynthesis could efficiently
produce hydrogen that could be used
as a clean fuel and also mop up
carbon dioxide from the atmosphere.
By covalently bonding a large number
of phthalocyanine molecules…
