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
