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.

Study suggests new nanomedicine treatment option for ovarian cancer

A paper published in the January issue of the journal Nanomedicine could provide the foundation for a new ovarian cancer treatment option -- one that would use an outside-the-body filtration device to remove a large portion of the free-floating cancer cells that often create secondary tumors.

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.
