Nanoengineered Materials Workshop to meet Sept. 16-18

The 'Electronic Transport in Nanoengineered Materials' workshop is sponsored by UChicago's Materials Research Science and Engineering Center. Among the approximately 70 participants will be physical chemists, who make new materials and study their properties, and theoretical physicists who specialize in the study of solid matter.

Carbon nanotubes twice as strong as once thought

New studies on the strength of these submicroscopic cylinders of carbon indicate that on an ounce-for-ounce basis they are at least 117 times stronger than steel and 30 times stronger than Kevlar, the material used in bulletproof vests and other products.

Putting a spin on light and atoms - How to build a better magnetometer

Researchers from the U.S. Department of Energy's Lawrence Berkeley National Laboratory, the University of California at Berkeley, and the Vavilov State Optical Institute in St. Petersburg, Russia, have now made sensitive measurements of magnetic fields by maintaining the spin polarization of atoms in an alkali-vapor magnetometer for more than 60 seconds at room temperature - a two-orders-of-magnitude improvement in this important measurement parameter over the best previous performance.

How do your crystals grow?

New research uses fluorescence correlation spectroscopy (FCS) to investigate the processes at the surface of a growing crystal. By focusing a laser on the crystal surface and measuring the resulting fluorescence, FCS can resolve dimensions as small as a single wavelength of the light.
