Researchers create smallest organic light-emitters

To help light up the nanoworld, a Cornell interdisciplinary team of researchers has produced microscopic “nanolamps” — light-emitting nanofibers about the size of a virus or the tiniest of bacteria.

In a collaboration of experts in organic materials and nanofabrication, researchers have created one of the smallest organic light-emitting devices to date, made up of synthetic fibers just 200 nanometers wide (1 nanometer is one-billionth of a meter). The potential applications are in flexible electronic products, which are being made increasingly smaller.

New nanocomposite processing technique creates more powerful capacitors

A new technique for creating films of barium titanate (BaTiO3) nanoparticles in a polymer matrix could allow fabrication of improved capacitors able to store twice as much energy as existing devices. The improved capacitors could be used in consumer devices such as cellular telephones – and in defense applications requiring both high energy storage and rapid current discharge.
