Conductive Metalorganic Framework Chemical Sensors

Technology Description This technology is a gas sensing device made of a highly oriented metal-organic framework (MOF) material on an oxide substrate. The MOF is also made conductive by the addition of a redox active molecule. The conductive MOF is made without using a gold substrate, and the method of assembling the MOF layers incorporating the redox...

Fiber Optic Infrared Absorption Gas Sensors with Metal-Organic Framework Materials

Technology Description The fiber-optic chemical sensing platform couples light guides with a metal-organic framework (MOF) and plasmonic nanomaterial sensing components to provide increased near-infared (NIR) detection sensitivity. The MOF thin films rapidly absorb and sense gases by leveraging a network of plasmonic nanocrystals that act at the NIR...

Method and Apparatus for Sample Analysis

PSU researchers have developed a novel way to collect, concentrate and analyze gas samples for analysis, primarily in environmental applications. By increasing pressure and performing analyses on a focused gas sample, this technology easily and cheaply enables continuous and real-time monitoring of air quality. Emission sources are more easily identified....

Nitrogen Dioxide Gas Sensor

PSU researchers have developed a new chemical gas sensor capable of detecting nitrogen dioxide (NO2) at levels less than 100ppb (two orders of magnitude more sensitive than current chemiluminescent based NOx sensors), having a dynamic linear range of parts per million to parts per billion, and a speed of detection of 60-120 seconds. Unlike existing...

Ambient Pressure NO2 Sensor

The measurement of nitrogen dioxide (NO2) is important to both environmental monitoring and to research of flame, combustion, and surface chemistry. Current methods and devices operate at very low, sub-ambient pressures, requiring a substantial pumping system and limiting their usefulness in applications in higher pressure environments where direct...
