Exhaled human breath is a combination of hundreds of gases including inorganic molecules such as NO, NH3 or CO, and volatile organic molecules such as acetone, ethane, and isoprene. Some of these gases are produced by the body as the result of physiological processes. Known as ‘biomarkers&rs…

Many freshwater bodies of the world suffer from the disastrous, interrelated combination of nearby wetland habitat loss, nitrogen loading, and toxic algal blooms. This problem is seen throughout the United States in nutrient heavy storm water ponds, drinking water reservoirs, and the Great Lakes. …

Thermoelectric effects enable direct conversion of thermal to electrical energy, which provides an alternative power generation and temperature conditioning. Although thermoelectric systems are environmentally friendly, the efficiency of thermoelectric devices cannot compete with current gold-stan…

Damping materials provide energy attenuation solutions for a variety of commercial applications. These materials are prominently used in the auto and aerospace industries and are also found in conventional building practices, and industrial settings. Most standard damping materials work in a limit…

Optical fibers are lightweight, small in diameter, and immune to electromagnetic interference. Signal attenuation over great distances is minimal and there is a high potential for large bandwidth data transfer. These qualities make optical fiber-based sensors an ideal candidate for measurements wh…
