  • Atomic Layer Deposition of Two Dimensional MoS2 on 150 mm Substrates

    O Criador:
    Valdivia, Arturo Herrera
    Abstract:
    Two-dimensional transition metal dichalcogenides (TMDs) have recently come under intense investigation as building blocks for van der Waals heterostructure electronics. One of the most promising TMDs is MoS₂, which transitions from an indirect bandgap (1.3 eV) in its bulk state to a direct band gap (1.8 eV) in its single...

  • Oxygenate Reactions over PdCu and PdAg Catalysts: Influence of Electronic and Geometric Effects

    O Criador:
    Bathena, Tanmayi
    Abstract:
    Bimetallic catalysis is a promising way to tune the catalytic properties of heterogeneous catalysts. In particular, bimetallic catalysts are extensively used to enhance the selectivity of monometallic catalysts in a variety of contexts, from oxidation catalysis to oxygenate coupling. In this work, we investigate PdxCuy/SiO2 and PdxAgy/SiO2 catalysts in the...

  • Applications of Magnetic Materials in Soft Robotics

    O Criador:
    Davis, William M.
    Abstract:
    Magnetic materials can be used in modern soft robotics as a method for external stimulus actuation and motion control. By combining aspects of biology and mechanics, devices are fabricated to create a structure capable of complex movement. Applications that these devices are subject to can be broken down into four...

  • Synthesis, surface treatment, and characterization of copper indium sulfide quantum dots

    O Criador:
    Alemu, Yagenetfere A.
    Abstract:
    The need for less toxic quantum dots (QDs) has led to a significant number of investigations related to copper indium sulfide (CIS) QDs. Lower toxicity and broad band absorbance width makes CIS QDs appealing for light emitting diodes (LEDs), lasers, sensors, bio-imaging, solar cells, and computing. The optical and electronic...

    O Criador:
    Li, Shiwen
    Abstract:
    Due to the advantages of the high surface area and high porosity, Metal-Organic Framework (MOF) materials are widely used in gas storage. As a typical MOF material, Zeolitic Imidazolate Framework-8 (Zif-8) has high selectivity and adsorption capability of carbon dioxide (CO2). In this thesis, we investigated the infrared absorption of...
