  • Investigation of MoS2 with Ambient Pressure X-ray Photoelectron Spectroscopy

    Creator:
    Dardzinski, Derek P.
    Abstract:
    Molybdenum disulfide (MoS2) has potential applications as a low-cost catalyst for the hydrogen evolution reaction (HER). Defects on MoS2, such as edge sites and sulfur vacancies, are known to be the major active sites for HER. Controlling the formation of these defects allows for the enhancement in reactivity of MoS2...

  • Restoring and Updating the Micralyne μTK

    Creator:
    Wong, Derek H.
    Abstract:
    The Micralyne microfluidic toolkit (μTK) was an instrument built by Micralyne in the early 2000’s. It was built for electrophoresis and has a sensitive laser-induced fluorescence detection system. The updates to the system were upgrading the control GUI from running in LabVIEW 5 (Windows XP, 2000) to LabVIEW 2012 (Windows...

  • Frequency-Dependent Rheological Characterization of Viscoelastic Materials Using Magnetic Nanoparticle Probes

    Creator:
    Myers, Renee C.
    Abstract:
    Extending rheological characterization methods to very small length scales is of interest. AC susceptometry using magnetic nanoparticle probes has been proposed for measurement of frequency-dependent rheological properties at the nanoscale. As this technique has been primarily used for ideally Newtonian fluids, this research aimed to extend this technique to viscoelastic...

  • Design of a Green Microbial Fuel Cell for Soft Robotics

    Creator:
    Van Volkenburg, Tessa
    Abstract:
    This work introduces the design and fabrication of a green-sourced and mostly biodegradable microbial fuel cell for use in soft robotic applications from environmental sensing to wastewater remediation. Theorized from other biodegradable fuel cells, this prototype achieved maximum power densities of 4.0 x 10−4 W/m2 in the single-chambered design and...
