Deep desulfurization of diesel fuel using a single phase photochemical microreactor

Creator:: Jones, Jacob Aaron
Abstract:: There is an urgent need to lower the concentration of sulfur in diesel fuels. Growing concern over environmental effects caused by burning sulfur-containing diesel has led the world to higher standards in fuel refinement. Because of these lower standards, many techniques have been researched to remove sulfur containing compounds or...

Data-driven imputation of miscibility of aqueous solutions via graph-regularized logistic matrix factorization

Creator:: Behnoudfar, Diba, Simon, Cory M., and Schrier, Joshua
Abstract:: Aqueous, two-phase systems (ATPSs) may form upon mixing two solutions of independently water-soluble compounds. Many separation, purification, and extraction processes rely on ATPSs. Predicting the miscibility of solutions can accelerate and reduce the cost of the discovery of new ATPSs for these applications. Whereas previous machine learning approaches to ATPS...

Co-treatment of Municipal Wastewater and Landfill Leachate in an Activated Sludge Sequencing Batch Reactor

Creator:: Bushee, Gavin A.
Abstract:: A year-long bench-scale treatability study was performed to assess the feasibility of using an activated sludge sequencing batch reactor (SBR) to treat a mixture of domestic wastewater and landfill leachate. A 50/50 (v/v) of domestic wastewater and landfill leachate was treated in a 1 L SBR operated on a 12...

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...

Controlling the Co-Precipitation of Colloidal PbSe Quantum Dots and Their Device Performance in a Diode Architecture

Creator:: McCrea, Tyler D.
Abstract:: In this work, colloidal PbSe quantum dots (QDs) are shown to be synthesized in a controlled manner by changing the growth time and reaction temperature in a microwave synthesis method. It is explained why quantum dots make such a unique material to create electronic devices and the specific benefits that...

Continuous Flow Microwave-Assisted Synthesis as a Potentially Scalable Nanomanufacturing Approach

Creator:: Albuquerque, Gustavo Henrique T. C. de
Abstract:: The development of nanomaterials and the potential enhancement of their chemical, mechanical, electrical, and optical properties have led to the investigation of methods for their synthesis at lower cost with enhanced performance for next generation devices. Along with the pursuit of new materials that exhibit properties of interest, industry requires...

Studies of Chitin Nanofiber Production and Photoluminescent Biosilica from Diatoms with and without Germanium

Creator:: LeDuff, Paul A.
Abstract:: There is significant interest in harnessing the biosynthetic capacities of photosynthetic diatom microalgae for the production of unique bioinspired nanomaterials. Specifically, this research focuses on understanding the photoluminescent properties of diatom biosilica and β-chitin nanofiber production in diatoms. Diatoms are single-celled microalgae that possess intricately patterned biosilica shells called, frustules....

Bioaugmentation of Pure and Enriched Cultures Fed Multiple Primary Substrates to Aerobically Cometabolize a Mixture of Chlorinated Solvents and 1,4-dioxane in Microcosms Containing Groundwater from a Department of Defense Site

Creator:: Laurance, Jon C.
Abstract:: Chlorinated solvents are common groundwater pollutants that often exist as mixtures resulting from the use of multiple solvents and their transformation into chlorinated daughter products. These sites are often co-contaminated with the solvent stabilizer 1,4-dioxane (1,4-D), which is not treated by traditional chlorinated solvent remediation techniques. Both 1,4-D and chlorinated...

Aerobic Cometabolism of 1,4-Dioxane and cis-Dichloroethylene by Gellan Gum and Polyvinyl Alcohol/Sodium Alginate Hydrogel Beads Co-Encapsulated with Rhodococcus rhodochrous Strain ATCC 21198 and Slow-Release Growth Substrates: Batch, Column, and Toxicity Studies

Creator:: Conway, Sean P.
Abstract:: 1,4-Dioxane (dioxane) and cis-dichloroethylene (cDCE) are compounds commonly found in industrial cleaning and degreasing agents that are frequently present as groundwater contaminants. In an effort to develop a more effective treatment method for these compounds, hydrogel beads were fabricated with either gellan gum or a combination of polyvinyl alcohol (PVA)...

Extensional characterization of weakly-viscoelastic fluids : methods & applications

Creator:: Marshall, Kristin A.
Abstract:: The addition of macromolecules to solvent, even in dilute quantities, can significantly alter a fluid's response in an extensional, or stretching, flow. When high-molecular-weight polymers are extended in solution, extensional thickening can result, yielding viscosities that are orders of magnitude larger than values found in shear. Examples of applications where...
