  1. Title: “Metal-Organic Frameworks: A Highly Tunable Class of Materials for Chemical Sensing with High Selectivity.”
  2. Abstract: A classic challenge in gas sensing is tunability of sensing material to suit the specific application. A new class of materials, metal- organic frameworks (MOFs), can take on thousands of forms, each with unique chemical adsorption properties. Metal-organic frameworks are made up of metal-cluster nodes connected by organic linkers. Changing the metal cluster or the organic linker can modulate the adsorptive properties. Growing a MOF-thin-film around a sensor effectively creates a gas-selective membrane that enhances the selectivity of the sensing material, which we demonstrate using a metal nanoparticle sensing layer on the CS-FET device (developed earlier by Prof. Javey’s group). The MOF-coated metal nanoparticle sensing layers show enhanced sensitivity to H2 and improved selectivity over H2S and NO2.Future work will include preparing a library of these materials and characterization of the material to better understand the mechanism.

    2. Title: “High pressure studies of calcium-aluminum-silicate hydrate (C-A-S-H)”
