Clemson University physics professor Apparao Rao has received a $1.2 million grant from the National Science Foundation (NSF) to explore the use of carbon nanomaterials for energy storage. The Clemson physics professor will lead a team of researchers from Clemson and the University of California-San Diego in developing novel types of electrochemical capacitors with blueprints for their scalability.
Organic catalysts are a breakthrough in the quest for inexpensive and efficient materials for environmentally friendly production of energy in fuel cells. A new study by physicists at Umeå University in Sweden provides better knowledge about key processes in producing these catalysts.

Researcher at Engineering and Materials Science, and Department of Chemistry and Smalley Institute of Nanoscale Science and Technology, Rice University, USA, put forward a comprehensive picture dubbed nanoreactor, which draws from ideas of step-flow crystal growth augmented by detailed first-principles calculations. The analysis adds a useful perspective on the synthesis of carbon nanotubes and its essential distinction from graphene.
