Portable acoustic inspection device

Early stages of portable acoustic inspection devices were designed for the U.S. Department of Defense. Since then, the technology has been used by the U.S. Defense Threat Reduction Agency, United Nations Weapons Inspectors, the Internal Revenue Service, the State Department and others.

Rubbercycle

RubberCycle™ addressed the problem of what to do with stockpiled tires. Scientists invented a bioprocess using sulfur-loving microorganisms that change the surface chemistry of waste tire rubber, enabling it to bond with virgin rubber. This cost-effective method of producing vulcanized rubber products, such as tires, performed better than those made of new rubber alone.

Plastic glass

Scientists developed a new way to make plastic virtually impermeable so it could be used to replace glass in new display technologies. Using plastics instead of glass would allow laptop computer monitors, cell phones and other flatpanel displays to be thinner, more rugged and lighter weight. The product is incorporated into many commercial products.
