Bearings Take On a New Roll
Conventional bearings have done their job for decades, but with increased energy costs, that job isn't good enough. In motor driven systems, experts estimate that 8.2 billion kWh/year are lost as a result of friction in bearings. Engineers claim they can do better by using improved bearing designs and lubricants.

Failing Before Their Time
Keeping on top of bearing condition is critical, with potentially severe consequences if symptoms are ignored. While oil and vibration analysis are most accurate, a thermal analysis is usually ignored until it's too late. This article describes the stages of bearing failure and several methods of monitoring bearing temperature to catch problems early.

Hot Idea for Cool Applications
Thermoelectric heating and cooling is nearly a century old, but research is finding new thermoelectric material applications such as cooling car seats. Engineered semiconductor materials and nanoscale structures make it practical. Thermoelectric devices promise to improve auto engine efficiency by converting waste heat into electricity. What other applications can you imagine?

Fair Play Evades Industrial Superpower
U.S. and other worldwide manufacturers could suffer if China continues its unfair trade practices. In particular, recent studies say that Chinese spying in America represents the greatest threat to U.S. technology. Flooding markets with cheap goods and creating unbalanced economic policies undermines the interests of many countries. An allegation of spying and theft in order to obtain new technology has begun to fuel the fire between nations. How can China's practices affect your career?

Nuclear Camera Nabs Smugglers
The threat of smuggling nuclear material may someday be thwarted with a newly devised neutron scatter camera. Unlike earlier methods, the neutron camera can see through thicker shielding and from greater distances. It also can detect the source and the amount of radiation present. Researchers at Sandia National Laboratories say they are interested in perfecting the camera, and will eventually work to make it portable.
