Memory training for metal structures

Structured surfaces have special properties. It would be desirable to make these properties switchable. This, for example, would allow for friction and adhesion to be specifically switched on and off on metallic surfaces. How to train structured surfaces for this effect has been under investigation by the junior research group 'Metallic Microstructures' at the Leibniz Institute for New Materials since January 2011.

A mix of tiny gold and viral particles - and the DNA ties that bind them

Scientists have created a diamond-like lattice composed of gold nanoparticles and viral particles, woven together and held in place by strands of DNA. The structure - a distinctive mix of hard, metallic nanoparticles and organic viral pieces known as capsids, linked by the very stuff of life, DNA - marks a remarkable step in scientists' ability to combine an assortment of materials to create infinitesimal devices.

New transistor for plastic electronics exhibits the best of both worlds

Researchers from the Georgia Institute of Technology describe a new method of combining top-gate organic field-effect transistors with a bilayer gate insulator. This allows the transistor to perform with incredible stability while exhibiting good current performance. In addition, the transistor can be mass produced in a regular atmosphere and can be created using lower temperatures, making it compatible with the plastic devices it will power.

An alternative to platinum counter electrode for dye-sensitized solar cells

Researchers in Japan have developed a ternary material with a core-shell structure consisting of multi-walled carbon nanotubes, an ionic liquid, and a conducting polymer. It was found that, when used as the counter electrode of dye-sensitized solar cells, the material exhibits photoelectric conversion efficiency as high as that of platinum.

The world can be powered by alternative energy, using today's technology, in 20-40 years

A new study analyzing what is needed to convert the world's energy supplies to clean and sustainable sources says that it can be done with today's technology at costs roughly comparable to conventional energy. But converting will be a massive undertaking on the scale of the moon landings. What is needed most is the societal and political will to make it happen.
