Methane (CH4) is the second most important greenhouse gas after carbon dioxide (CO2). Human activity related radiative forcing by methane accounts for about half of that caused by CO2. In the U.S., the largest industrial source of CH4 is oil and gas systems. Fugitive sources are often identified as potentially large sources of CH4 emissions; however, multiple measurement challenges inhibit more co ...

In order to promote human and environmental health, infrastructure must become safer, longer lasting, and more sustainable. Telecommunication structures with resiliency to extreme conditions are particularly beneficial because they allow communications to continue even in emergency situations. IsoTruss Inc. will develop a composite-reinforced concrete foundation that will increase resiliency witho ...

Approximately 25% of all anthropogenic generated methane comes from the oil and gas industry, and it is estimated that ~6% of those emissions are from storage tanks used in the production phase. Methane has a shorter lifetime in the atmosphere but has a significantly greater warming potential than carbon dioxide on short time scales. The emissions from these storage tanks are not well known, and n ...

The proposed device is a compact, portable, and robust battery-powered analytical instrument for monitoring of ultra-low concentrations of various VOCs in complex backgrounds. Our technology is based on principles of analytical gas chromatography (GC), utilizes scrubbed ambient air as carrier gas and a novel highly integrated multisensory platform as a detector. Due to the implementation of a mult ...

The EPA has identified a need for new methods and instrumentation to characterize size, shape, and composition of microplastics, especially in the size range of 1 µm – 1 mm. To meet the needs identified by EPA, we propose development of a portable sensor for improved microplastic sampling and characterization useable at remote measurement sites or fixed installations. The sensor would be connec ...

Espira Inc. has developed ElectroPur, a modular point-of-use (POU) drinking water disinfection and pathogen sensing system. The ElectroPur system includes an electrocatalytic titanium-based disinfection reactor that inactivates biological pathogens (bacteria, viruses, and protozoa) through the creation of powerful oxidative radicals and a highly sensitive biological sensor that can detect a range ...

Sulfur dioxide (SO2) is one of the six "criteria" pollutants listed in the Clean Air Act that are regulated under the EPA National Ambient Air Quality Standards (NAAQS). SO2 is the most abundant anthropogenic sulfur compound in the troposphere, and is mainly emitted through coal and petroleum combustion, petroleum refining, and metal smelting operations. Although national ambient air quality trend ...

To monitor the freshness of fresh produce in storage and during transportation, we propose using a gas sensor based on swept]wavelength broadly tunable external cavity quantum cascade lasers (EQCCLs).These sensors detect, identify, and quantify multiple chemical species in the airspace near the sensor continuously and in real]time, with part]per]billion level sensitivity. The sensors will ...
