The EFSA is soliciting opinions on its draft scientific paper that will address nanotechnologies for food and feed safety. This paper request comes from the European Commission, as they want to assess if current food safety guidelines adequately cover nano-engineered materials into food and feed products. People may submit comments via the EFSA website through December 1, 2008. To learn more, please visit us at www.efsa.europa.eu

The venture deal was signed this month by the State Nanotechnology Corporation (also known as Rosnano), engine building company Saturn, and Gazprombank, and the deal will focus on building equipment for the aviation and engineering industries. Rosnano will hold the majority share in the deal. The agreement will focus on the production of hard-alloy tools for airplane engines for the Russian market. In time, they hope to enter their product line into the international marketplace.

The Australian government has allotted $100 million towards a science program that provides support for micro and nano-fabrication research. The Australian Fabrication Facility will bring advanced equipment to seven university-based centers. Australia

The ability to mimic micro- and nanostructures existing in biosystems is of great interest because it provides tools and platforms for many fundamental biophysical studies and technological applications.

Computer-aided molecular design has led to the fabrication of a nanotech material for solar cells. Combining electrically conductive polymers, transition metal atoms, and spin-coating to form thin films could lead to solar cells with two major advantages that would make them more efficient at converting light to electricity. From Ohio State University, via AAAS EurekAlert “New Solar Energy Material Captures Every Color of the Rainbow“:

Researchers have created a new material that overcomes two of the major obstacles to solar power: it absorbs all the energy contained in sunlight, and generates electrons in a way that makes them easier to capture.

Ohio State University chemists and their colleagues combined electrically conductive plastic with metals including molybdenum and titanium to create the hybrid material.

“There are other such hybrids out there, but the advantage of our material is that we can cover the entire range of the solar spectrum,” explained Malcolm Chisholm, Distinguished University Professor and Chair of the Department of Chemistry at Ohio State.

The study appears in the current issue of the Proceedings of the National Academy of Sciences (PNAS) [abstract].

…To design the hybrid material, the chemists explored different molecular configurations on a computer at the Ohio Supercomputer Center. Then, with colleagues at National Taiwan University, they synthesized molecules of the new material in a liquid solution, measured the frequencies of light the molecules absorbed, and also measured the length of time that excited electrons remained free in the molecules.
