Putting the squeeze on batteries

By Volker Steger on Nov. 21, 2011, noon

Professor Craig Arnold is working to make lithium-ion batteries last longer and provide more energy.

People depend upon lithium-ion batteries every day to power cellphones, laptops and other electronic devices, and perhaps one day to run cars. This video shows how Craig Arnold, an associate professor of mechanical and aerospace engineering at Princeton University, is working to make those batteries last longer and provide more energy.

Koel applies science of surface chemistry to fusion research at PPPL .

The fusing together of atoms releases vast amounts of energy, but the process can take place only at extremely high temperatures. For fusion to be the basis of the power plant of the future, scientists need to find ways to keep the process from cooling. By using his expertise in surface chemistry, chemical and biological engineering professor Bruce Koel is working with scientists at the Princeton Plasma Physics Lab to address this goal.
