Researchers at Eindhoven University of Technology (TU/e, Netherlands) have developed a replacement for indium tin oxide (ITO), an important material used in displays for all kinds of everyday products such as TVs, telephones and laptops, as well as in solar cells. Unfortunately indium is a rare metal, and the available supplies are expected to be virtually exhausted within as little as ten years. The replacement material is a transparent, conducting film produced in water, and based on...

Strong, nanostructured membrane enables scaling for practical clean-energy applications Materials scientists at the Harvard School of Engineering and Applied Sciences (SEAS) and SiEnergy Systems LLC have demonstrated the first macro-scale thin-film solid-oxide fuel cell (SOFC). While SOFCs have previously worked at the micro-scale, this is the first time any research group has overcome the structural challenges of scaling the technology up to a practical size with a proportionally higher...

With the first observation of thermoelectric effects at graphene contacts, University of Illinois researchers found that graphene transistors have a nanoscale cooling effect that reduces their temperature. Led by mechanical science and engineering professor William King and electrical and computer engineering professor Eric Pop, the team will publish its findings in the April 3 advance online edition of the journal Nature Nanotechnology. The speed and size of computer chips are limited by how...

The batteries in Illinois professor Paul Braun's lab look like any others, but they pack a surprise inside. Braun's group developed a three-dimensional nanostructure for battery cathodes that allows for dramatically faster charging and discharging without sacrificing energy storage capacity. The researchers' findings will be published in the March 20 advance online edition of the journal Nature Nanotechnology. Aside from quick-charge consumer electronics, batteries that can store a lot of...

Precision measurement in the world of nanoparticles has now become a possibility, thanks to scientists at UC Santa Barbara. The UCSB research team has developed a new instrument capable of detecting individual nanoparticles with diameters as small as a few tens of nanometers. The study is published online this week by Nature Nanotechnology, and will appear in the April print issue of the journal. "This device opens up a wide range of potential applications in nanoparticle analysis," said...
