'Homegrown' hybrid solar cell aims for low-cost power

Argonne National Laboratory have refined a technique to manufacture solar cells by creating tubes of semiconducting material and then 'growing' polymers directly inside them. The method has the potential to be significantly cheaper than the process used to make today's commercial solar cells.

Interdisciplinary research team developing novel drug detection technology

With the support of a $2.7 million Recovery Act grant from the National Institute of Drug Abuse (NIDA) an interdisciplinary team headed by Vanderbilt chemist John McLean and physicist John Wikswo will attempt to determine whether an individual's white blood cells retain chemical memories of exposure to drugs like cocaine and alcohol that can be read reliably and unambiguously.
