  • Design And Testing Of A Flow Electrolyzer For Selective Seawater Electrolysis

    Creator:
    Chou, Kuan-Hsun
    Abstract:
    Hydrogen is of great interest as a fuel, as its oxidation produces benign water (without CO₂ emissions), its gaseous form can be transported in existing pipe infrastructure, and it can be obtained via renewable electricity from water. However, current hydrogen production is mainly produced from fossil fuels (e.g. methane), exacerbating...

  • Detection techniques for biomolecules using semi-conductor nanocrystals and magnetic beads as labels

    Creator:
    Chatterjee, Esha
    Abstract:
    Continued interest in the development of miniaturized and portable analytical platforms necessitates the exploration of sensitive methods for the detection of trace analytes. Nanomaterials, on account of their unique physical and chemical properties, are not only able to overcome many limitations of traditional detection reagents but also enable the exploration...

  • Transition Metal Oxides for Aqueous Electrochemical Energy Storage

    Creator:
    Jiang, Heng
    Abstract:
    In the 21st century, environmental deterioration is now an indisputable fact. Reliable and economically viable electricity systems based on renewable sources are urgently needed to replace the environmentally detrimental fossil fuels. The feasibility of incorporating renewable-but-intermittent solar and wind energy heavily depends on the development of cost-effective and safe technologies,...

  • Photoluminescence properties investigation of germanium inserted biosilica generated by bioreactor culture of marine diatom Nitzschia frustulum

    Creator:
    Qin, Tian
    Abstract:
    The purpose of this research was to investigate the optoelectronic properties of the Ge doped biosilica, mainly focused on the photoluminescence (PL) properties of diatom frustules of N. frustulum that contain metabolically inserted germanium oxide produced by a two-stage photobioreactor cultivation process. In order to explain the observed PL intensity...

  • Method development for characterizing the hydrophobicity of engineered nanoparticles

    Creator:
    Lee, Fang Yu
    Abstract:
    Characterizing the hydrophobicity of nanoparticles can help us understand their fate and transport in the environment, as well as how nanoparticles may interact with biological systems. However, contact angle and partition coefficient have limitations in measuring the hydrophobicity of nanoparticles, thus promising methods to measuring the hydrophobicity of nanoparticles are...

  • Organic-solvent resistant ultrafiltration and nanofiltration membrane modules for separation and purification of nanoparticles

    Creator:
    Kim, Taehyeong
    Abstract:
    The intriguing size- and shape dependent properties of nanoparticles have garnered recent attention in many science and engineering areas. When the particle size is in the nanometer size range, the material exhibits very different properties such as surface plasmon resonance (of gold nanoparticles) and superparamagnetism (of iron oxide nanoparticles). The...

  • Design Principles of Transition Metal X-ide Catalysts for Electrochemical Oxygen Reduction and Evolution Reactions: In-Situ X-ray Spectroscopy Studies

    Creator:
    Wang, Maoyu
    Abstract:
    Hydrogen is the green fuel that can be produced from water through electrolysis and used via hydrogen fuel cells to generate electricity with zero carbon dioxide emission. The commercialization of electrolyzers and fuel cells is the critical step to achieving global carbon neutrality. However, it is severely hampered by the...

  • Fabrication and application of polymer based microfluidic devices

    Creator:
    Koesdjojo, Myra T.
    Abstract:
    The concept of reducing laboratory operations in scale such that they fit on a microfluidic chip has been met with great enthusiasm. Lab-on-a-chip devices promise to be cost effective to operate due to reduced reagent consumption, have the potential to offer shorter analysis times due to their short path lengths,...

    Abstract:
    Cobalt germanides have been widely studied as semiconductor contact materials, but recent theoretical studies suggest that they may also be excellent catalysts for methane steam reforming with stabilities and activities comparable to noble metal catalysts. In order to study the catalytic activity of cobalt germanides, it is critical to first...
