Structure of plastic solar cells impedes their efficiency (October 5, 2010). A team of researchers from NC State--including Dr. Harald Ade--and the U.K. has found that the low rate of energy conversion in all-polymer solar-cell technology is caused by the structure of the solar cells themselves. They hope that their findings will lead to the creation of more efficient solar cells. The researchers’ results appear online in Advanced Functional Materials and Nano Letters. NC State News Service
Mimicking nature, water-based ‘artificial leaf’ produces electricity (September 24, 2010). A team led by Dr. Orlin Velev has shown that water-gel-based solar devices – “artificial leaves” – can act like solar cells to produce electricity. The findings prove the concept for making solar cells that more closely mimic nature. They also have the potential to be less expensive and more environmentally friendly than the current standard-bearer: silicon-based solar cells. NC State News Service
Study shows nano-architectured aluminum has steely strength (September 8, 2010).

Hiding risks can hurt public support for nanotechnology (May 4, 2010). A new national survey on public attitudes toward medical applications and physical enhancements that rely on nanotechnology shows that support for the technology increases when the public is informed of the technology’s risks as well as its benefits – at least among those people who have heard of nanotechnology. The survey, which was conducted by Dr. Michael Cobb at NC State and researchers at Arizona State University, also found that discussing risks decreased support among those people who had never previously heard of nanotechnology – but not by much.

Smart coating opens door to safer hip, knee and dental implant (February 3, 2010). Researchers at NC State have developed a “smart coating” that helps surgical implants bond more closely with bone and ward off infection. When patients have hip, knee or dental replacement surgery, they run the risk of having their bodies reject the implant. But the smart coating developed at NC State mitigates that risk by fostering bone growth into the implant. The coating creates a crystalline layer next to the implant, and a mostly amorphous outer layer that touches the surrounding bone. The amorphous layer dissolves over time and encourages bone growth.
