  • Application of transport-reaction modeling to constrain biogeochemical processes in marine sediments

    Creator:
    Hong, Wei-Li
    Abstract:
    Quantifying the mass transport through marine sediments, and the geochemical response to such flow with numerical models has become a common and powerful approach for geochemical data interpretation. In this dissertation, I developed and applied transport-reaction models to unravel complex and interdependent reactions involving carbon, sulfur and silica transformations in...

  • Electrical Conductivity in Mixed-Species Biofilms for Enhancing Energy Generation in Anaerobic Microbial Systems

    Creator:
    Li, Cheng
    Abstract:
    Further enhancement of energy generation is desired for practical application of anaerobic microbial systems such as microbial fuel cells (MFC) and anaerobic digesters (AD). A possible approach is to enhance the ability of microbial communities to transfer electron extracellularly in the form of electrical current. Critical to perform direct extracellular...

  • Consider the community : developing predictive linkages between community structure and performance in microbial fuel cells

    Creator:
    Lesnik, Keaton Larson
    Abstract:
    The complex, dynamic nature of microbial communities in both natural and engineered environments complicates the work of scientists and engineers who wish to channel microbial interactions for societal good. The successful management of these communities towards engineering goals is dependent on developing predictive linkages between community structure and functional outputs....

  • Low-power successive approximation analog to digital converter with digital calibration

    Creator:
    Li, Wei
    Abstract:
    IC designers are continuously facing the challenges from reduced CMOS feature sizes and supply voltages. ADCs that deliver satisfactory resolutions/speeds while utilizing the state-of-the-art technologies to save power are in high demand. The analog circuits are more and more assisted by various digital calibration techniques to get boosted performances. This...

  • Microbial fuel cell for wastewater treatment : heavy metal removal, sewage sludge treatment, and its potential application in wastewater reuse in irrigation

    Creator:
    Abourached, Carole
    Abstract:
    While water scarcity and energy demand are continuously increasing in the world, alternative sources are needed to meet the requirement of a growing population. Microbial Fuel Cell (MFC) is a sustainable technology that converts organic matter in wastewater into electricity, thus it can be a potential alternative source for water...

  • Cathode development and reactor design for scaling-up microbial fuel cells

    Creator:
    Janicek, Anthony M.
    Abstract:
    Developing new wastewater treatment technologies which will off-set the high-energy cost associated with treatment is necessary to maintain both water and energy security. Microbial fuel cell technology represents one such option. However, there are still many obstacles to overcome before practical application of this technology can be realized. Improving cathode...

  • Enhancing Hydrogen Production using Single Chamber Microbial Electrolysis Cells by Tackling Hydrogen Scavengers

    Creator:
    Wang, Luguang
    Abstract:
    Biological hydrogen production from renewable feedstocks was reckoned as a promising method for sustainable energy production. Bioelectrochemical hydrogen production using microbial electrolysis cells (MECs) demonstrated superiorities over the conventional methods for hydrogen production. The introduction of the membrane-less single chamber design further improved the feasibility of MECs for practical application,...

  • Storage Battery Chemistries with Earth Abundant Charge Carriers

    Creator:
    Hong, Jessica Junghwa
    Abstract:
    The demand for the development of sustainable energy is an all time high as we burn through limited fossil fuel reserves and as environmental concerns rise every year. Renewable energy sources such as wind and solar power have limitations due to inconsistent power supply that cannot meet the regular needs...

  • Development of fragmentation techniques in mass spectrometry for biological applications

    Creator:
    Ji, Hong
    Abstract:
    In this dissertation, I present the work of developing more efficient and economical techniques for fragmenting large bio-molecules, and ultimately making mass spectrometry a more powerful tool in proteomics, DNA sequencing, and other areas of biomolecular analysis. Aiming at lowering the installation and operating cost, and delivering electron capture dissociation...

  • Electronic Stability of Metal Halide Perovskites

    Creator:
    Hong, Min Ji
    Abstract:
    Despite near unanimous opinion on the consequences of climate change by scientific community, the rate at which carbon is emitted into the atmosphere continues to increase. The need for a clean and sustainable source of energy is therefore one of humankind's most urgent challenges. Solar energy is the most abundant...
