Researchers from North Carolina State University have for the first time successfully coated polymer implants with a bioactive film. The discovery should improve the success rate of such implants – which are often used in spinal surgeries.

The polymer used in these implants, called PEEK, does not bond well with bone or other tissues in the body. This can result in the implant rubbing against surrounding tissues, which can lead to medical complications and the need for additional surgeries. (more…)

UD doctoral student studies ways to improve lithium battery performance

Lithium batteries are used in many devices such as cell phones, computers and cameras, among others.

University of Delaware doctoral student Wei-Fan Kuan is investigating ways to improve membranes used in lithium batteries by capitalizing on the innate properties of block copolymers.

It is work that he believes will become increasingly important as the components in electronic devices continue to get smaller. (more…)

*Research says test performance improves when students write about their worries*

Sian Beilock, lead author of a new study that appears on January 13 in the journal Science, says writing about test-related worries for ten minutes immediately before taking an exam is an effective way to improve test scores in classroom settings.

“By writing down one’s negative thoughts, students may come to realize that the situation is not as bad as they thought or that they are prepared to take it on,” said Beilock, an associate professor of Psychology at the University of Chicago. “As a result, they worry less during the test.” (more…)
