متن کاملVolatile organic compound detection using nanostructured copolymers.
Regioregular polythiophene-based conductive copolymers with highly crystalline nanostructures are shown to hold considerable promise as the active layer in volatile organic compound (VOC) chemresistor sensors. While the regioregular polythiophene polymer chain provides a charge conduction path, its chemical sensing selectivity and sensitivity can be altered either by incorporating a second poly...
متن کاملBreath measurements as volatile organic compound biomarkers.
A brief review of the uses of breath analysis in studies of environmental exposure to volatile organic compounds (VOCs) is provided. The U.S. Environmental Protection Agency's large-scale Total Exposure Assessment Methodology Studies have measured concentrations of 32 target VOCs in the exhaled breath of about 800 residents of various U.S. cities. Since the previous 12-hr integrated personal ai...
متن کاملCharacterization of Volatile Organic Compound Profiles of Bacterial Threat Agents
Volatile organic compound (VOC) profiles are potentially an underutilized class of threat agent signatures that may be exploited in the identification of threat agents. In the present study we first focused on determining if VOC profiles collected from liquid culture headspace could be utilized to differentiate between bacterium of different genus, in this case Bacillus and Yersinia. The second...
متن کاملA global model of natural volatile organic compound emissions
Numerical assessments of global air quality and potential changes in atmospheric chemical constituents require estimates of the surface fluxes of a variety of trace gas species. We have developed a global model to estimate emissions of volatile organic compounds from natural sources (NVOC). Methane is not considered here and has been reviewed in detail elsewhere. The model has a highly resolved...
