Electrochemical Micro-sensors for Probing Bacterial Metabolic Behavior with Scanning Electrochemical Microscopy

Creator:: Jayathilake, Nadeeshani M.
Abstract:: Dental plaque is one of the well-characterized biofilms in the human body. Oral bacterial species play vital roles in maintaining healthy bacterial homeostasis as well as causing oral infections. Many of the oral diseases are caused by opportunistic pathogens, and therefore, the bacterial metabolic activities become important in dictating their...

Immobilization of Methylosinus trichosporium OB3b in a Biolamina Plate Reactor for the Oxidation of Methane to Methanol

Creator:: Fuchs, Brian K.
Abstract:: Methane is a flammable gas that is the main component of natural gas. It is a highly potent greenhouse gas, and accounts for about 20% of greenhouse gas emissions. Methane is routinely flared in many industrial processes without harnessing any of its energy. The environmental impact and wasted energy potential...

Model Predictive Control for Optimum Algal Growth

Creator:: Juneja, Ankita
Abstract:: Microalgae has been under careful consideration as a sustainable feedstock for renewable fuel recently due to its year round production with high energy yields per unit area, reduced need for arable land, water treatment benefits with nutrient cycling, and minimal competition with the food industry. Despite of all these advantages,...

Probing the Biophysical interactions of Anti-Microbial Peptide WLBU2 Using Model Membrane Systems

Creator:: Golbek, Thaddeus W.
Abstract:: WLBU2 is an engineered cationic amphiphilic peptide that targets Gram-positive and Gram-negative bacteria, and envelopes endotoxin while avoiding other cell types. The exact mechanism of how WLBU2 targets, binds, and disrupts bacterial cell membranes is still not completely known. Thus, the overall goal of this investigation is to determine the...

Biochemical conversion of lignocellulosic biomass to ethanol : experimental, enzymatic hydrolysis modeling, techno-economic and life cycle assessment studies

Creator:: Kumar, Deepak
Abstract:: Ethanol production from lignocellulosic feedstock has been under intense scrutiny as a transportation fuel due to its potential to address concerns of increasing energy consumption, limited fossil energy resources, climate changes due to greenhouse gas emissions from fossil fuels, and especially use of non-food biomaterials, which address the biggest limitation...

Effects of ultraviolet illumination and a parylene-A activation layer on the gas phase sensing characteristics of ZnO nanobridges

Creator:: Mason, Ashley D.
Abstract:: ZnO nanowires (NWs) are good candidates for chemical sensing because of their high surface-to-volume ratio. In this work, ZnO nanobridge sensors were fabricated utilizing a novel method which uses carbonized photoresist (C-PR) as a nucleation layer. The use of C-PR allows simultaneous growth and integration of NWs to lithographically-defined features....

Investigating the Quality Dynamics of American Aroma Hops Intended for Dry-Hopping Beer

Creator:: Lafontaine, Scott R.
Abstract:: Historically, brewers have used dry-hopping (a cold extraction of nonvolatile and volatile chemicals from hops into fermenting or finished beer) to increase the microbial stability and shelf life of their beer. As hoppy beer styles have gained in popularity over the last decade (2007-2017), the objective of dry-hopping has turned...

Per- and Polyfluoroalkyl Substances (PFASs) and Aqueous Film-Forming Foam Impacted Sites : New PFAS Discovery and Sorption of Anionic, Zwitterionic, and Cationic PFASs

Creator:: Barzen-Hanson, Krista A.
Abstract:: Public attention and concern about per- and polyfluoroalkyl substances (PFASs) are increasing due to detection of PFASs in drinking water supplies, the environment, including remote locations, and wildlife and to the lowering of the federal health advisory levels of perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) in drinking water. Aqueous film-forming...

Displacement-based fluorescent microRNA biosensors : design principles and analytical metrics

Creator:: Larkey, Nicholas E.
Abstract:: One post-transcriptional mechanism that regulates the progression of cancer and other diseases involves small 22-23 nucleotide sequences called microRNA (miR). Early detection of small changes in concentration of these biomarkers holds potential to diagnose diseases at their earliest stages. Use of current nucleic-acid based biosensors, like molecular beacons, for in...

Synthesis of Intercalation Compounds and Nanocomposites of Inorganic Layered Hosts

Creator:: Liyanage, Medagama Liyanage Amila Udayanga
Abstract:: Novel synthetic strategies are developed to prepare new intercalation compounds and nanocomposites with several layered hosts (NiPS₃, Na-montmorillonite, MoS₂ and MoO₃). In these products, alkali metals are ionic intercalates and linear polymers, dendrimers or amines act as co-intercalates. In addition to new synthetic approaches, new structures are identified and characterized....
