New Hybrid Solar Cells combine Nanotech with plastics
A new generation of solar cells that combines nanotechnology
with plastic electronics has been launched with the development of a
semiconductor-polymer photovoltaic device by researchers with the U.S.
Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and
the University of California at Berkeley (UCB).

AMES Lab Researchers create organic
compounds without solvents
When chemists want to combine two or more organic
materials,
ordinarily they use a solvent to carry out a reaction that results in the
desired compound. Researchers at the U.S. Department of Energy's Ames Laboratory
have found a way to combine organic materials in solid state without the use of
solvents. This revolutionary solvent-free process means that environmentally
harmful solvents, such as benzene, dichloromethane and others, could be removed
from many of the chemical processes used to produce millions of consumer and
industrial products.

IBM Creates World's Highest
Performing Nanotube Transistors
IBM announced it has created the highest
performing nanotubes transistors to date and has proven that carbon
nanotubes (CNTs), tube-shaped molecules made of carbon atoms that are
50,000 times thinner than a human hair, can outperform the leading
silicon transistor prototypes available today.

Market
Opportunities are growing in Microfluidic Biomedical Systems
Improved microfluidic channels are playing a key role in the next generation
of biomedical applications. New advances in materials have brought forth much
better and tinier microchannels, closing the loop between in vitro (test tube)
diagnostics and in vivo (inside the body) therapies for medical problems using
micro- fluidic drug-delivery systems. The optimism is not without some
impressive market projections, though some are more bullish than others.

A new fabrication technique could revolutionize the production
of organic photonic-crystal lasers.
Japanese researchers at NTT's
Basic Research Laboratory in Kanagawa claim to have come up with a
simple and cost effective method to fabricate photonic-crystal lasers.
The researchers say that their direct nanoprinting approach not only
saves time but could slash production costs by a factor of 100.

Organic molecules acting as templates on metal surfaces
-Applications of
large organic molecules in nanoelectronics.
The adsorption of
large organic molecules has recently attracted interest from a fundamental point
of view and for prospective applications in nanoelectronics. Ideally, to create
functional mono-molecular or hybrid-molecular devices, it is necessary to
develop an architecture for the interconnection of individual molecules,
molecular devices and wires, in a planar conformation and with atomic precision,
to one end of nanoscale metallic contacts
