Gas sensors can provide information about the presence of dangerous gases in industrial and residential sites, allowing for improved environmental protection and human health and safety. In order to enable ubiquitous wireless monitoring of combustible and toxic gases, sensor elements with low power consumption are required. Two common types of gas sensors, namely calorimetric and conductometric sensors, rely on heated sensor elements to activate the appropriate reactions with the gas of interest, resulting in high power requirements to maintain the necessary operating temperatures....

Four million people died in 2002 due to diabetes related conditions[1]. Diabetes is the leading cause of adult blindness, end-stage kidney disease and amputations as a result of diabetic neuropathy. People with diabetes are two to four times more likely to have coronary heart disease and stroke than people who do not suffer from the disease. ...

Micro- and Nano-electromechanical Systems (MEMS and NEMS) consist of devices which can sense and actuate on the micrometer and nanometer scales. A number of MEMS devices have been commercialized, including accelerometers, gyroscopes, pressure sensors, and micromirror displays. The most common structural layer used in this technology is polycrystalline silicon, which is adequate for MEMS/NEMS devices operating in ambient environments; however, the use...

In recent years, the photovoltaic market has grown significantly as module prices have continued to come down. Continued growth of the field requires higher efficiency modules at lower manufacturing costs. In particular, higher efficiencies reduce the area needed for a given power output, thus reducing the downstream balance of systems costs that scale with area such as mounting frames, installation, and soft costs. Cells and modules made from III-V materials have the highest demonstrated efficiencies to date but are not yet at the cost level of other thin film technologies, which...
