cling,” Tour said. “Since the tin oxide particles are only a few nanometers in size and permitted to remain that way by being dispersed on GNR surfaces, the volume changes in the nanoparticles are not dramatic. GNRs also provide a light- weight, conductive framework, with their high aspect ratios and extreme thinness.”
The researchers pointed out the work is a “starting point for exploring the composites made from GNRs and other tran- sition metal oxides for lithium storage applications.” Lin said the lab plans to build batteries with other metallic nanopar- ticles to test their cycling and storage capacities. Co-authors of the paper are Rice graduate students Zhiwei Peng, Changsheng Xiang, Gedeng Ruan and Zheng Yan and Douglas Natelson, a Rice professor of physics and astronomy and of electrical and computer engineering. Tour is the T.T. and W.F. Chao Chair in Chemistry as well as a professor of mechanical engineering and materials science and of com- puter science at Rice.
Boeing, the Air Force Office of Scientific Research, Sandia National Laboratory and the Office of Naval Research sup- ported the research.

ustainable manufacturing was highlighted in several papers and presentations at the annual NAMRC-MSEC advanced
manufacturing conference June 10–14 in Madison, WI. The North American Manufacturing Research Conference of SME and the Manufacturing Science and Engineering Conference of ASME was co-located at the University of Wisconsin-Madison with more than 400 academic, government and industry re- searchers and manufacturing leaders in attendance. Sustainability indicators, which have been little employed on the process level, are applied to grinding processes in a
expand the Introducing EQUATOR™
possibilities of gauging
—the revolutionary system that fi nally creates a solution between custom gauging and CMMs
Nothing compares to Equator™ The new Renishaw Equator™ is a dramatic departure from the constraints of choosing either a custom gauging solution or a trip to the CMM. Experience up to 70% savings with signifi cantly reduced fi xture, installation and maintenance costs. Different parts, same Equator—never buy another custom gauge.
Nothing compares like Equator™
Highly repeatable Swap parts in seconds Fast form measurement
Automation and feedback Out-of-the-box installation
Expand process control to the next level.
