Understanding MOF Gas Entrapment Through Modeling

Metal organic frameworks (MOF) were created for the capture of noble gases (NG). They were tested to see which would be the most efficient and selective. MOFs are synthetic materials that are used in a variety of purposes: gas separations, catalysis reactions, drug delivery, and gas storage. In a previous study, there was an extremely long retention time of NG within the Ca-MOF material. Between 30-65 % of the NG was never recovered even under vacuum and at 150 °C. An understanding of this retention at a fundamental level is needed for utilizing the MOF material in industry or other applications

System and method for remote detection and location of gas leaks

A system for monitoring for a gas leak from a gas containing structure is disclosed. The system includes a lens that directs an image of a scene of interest through an optical filter onto a detector. The filter is associated with the lens and the filter has one or more passbands that passes wavelengths which match one or more emission or reflectively wavelengths of the gas being monitored. A detector receives the image after the image passes through the lens and the filter. The detector generates image data representing the scene including the gas containing structure. A processor is configured to process the image data by executing machine executable code stored on a memory. The machine executable code processes the image data to identify turbulence flows in the image data such that turbulence flow indicates a gas leak, and generate and send an alert in response to the identification of a turbulence flow.
