Monte Carlo random walk simulation as a complement to experimental and theoretical approaches : application to mass transfer in fish muscle tissue

Creator:: Almonacid-Merino, Sergio Felipe
Abstract:: Mass transfer processes in food systems, such as solute infusion, are poorly understood because of their complex nature. Food systems contain porous matrices and a variety of continuous phases within cellular tissues. Mass transfer processes are generally not pure diffusion: often convection, binding and obstructing diffusion will occur. Monte Carlo...

Photobiological hydrogen production from the cyanobacterium Synechocystis sp. PCC 6803 encapsulated in sol-gel processed silica

Creator:: Dickson, David J.
Abstract:: Photobiological hydrogen production from live cells of the cyanobacterium Synechocystis sp. PCC 6803 encapsulated in silica gel was investigated. Hydrogen is a dense energy carrier with potential to reduce dependence on fossil fuels, provided a renewable and sustainable means of production can be achieved. Under certain conditions, Synechocystis sp. PCC...

Metabolic engineering of cyanobacteria to optimize photobiological hydrogen production

Creator:: Luterra, Markael
Abstract:: Photobiological hydrogen production -- the use of photosynthesis to split water into hydrogen and oxygen -- presents an opportunity for efficient and large-scale solar biofuel development. One of the major challenges in this area is competition for reductant between the hydrogen-evolving hydrogenase enzyme and other metabolic pathways. In this work...

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...

Enhancing hydrogen production in microbial electrolysis cells through development of platinum-free cathode and improvement of reactor design

Creator:: Hu, Hongqiang
Abstract:: Microbial electrolysis provides a new approach for hydrogen generation from renewable biomass. At current stage, the most likely limiting factors for successful scale up of this technology are the large internal resistance and high fabrication cost. This dissertation presents an attempt to overcome these limitations by investigating novel microbial electrolysis...

Optimization studies in preparative chromatography of biomolecules

Creator:: Ramanan, Sundar
Abstract:: Optimization of preparative nonlinear chromatography was carried out for the first time for a biomolecule mixture. Conventional wisdom on optimization, which roots from analytical chromatography, dictates optimizing resolution in an analytical column and obtaining similar separation in a large column for isolation. Such a method of optimization significantly under uses...

Physiological, proteomic, and whole-genome transcriptional responses of Nitrosomonas europaea to heavy metals (Zn²⁺,Cd²⁺, Cu²⁺, and Hg²⁺) and cyanide : identification of heavy metals and cyanide stress response genes

Creator:: Park, Sunhwa
Abstract:: Nitrosomonas europaea (ATCC19718) participates in the biological removal of nitrogen from wastewater by oxidizing ammonia to nitrite, the first step in nitrification. This bacterium is sensitive to heavy metals (Zn²⁺, Cd²⁺, Cu²⁺, and Hg²⁺) and cyanide, compounds commonly encountered in wastewater treatment plants. Therefore, we characterized physiological and transcriptional responses...

Synthesis of colloidal metal oxide nanocrystals and nanostructured surfaces using a continuous flow microreactor system and their applications in two-phase boiling heat transfer

Creator:: Choi, Chang-Ho
Abstract:: Metal oxide nanocrystals have attracted significant interests due to their unique chemical, physical, and electrical properties which depend on their size and structure. In this study, a continuous flow microreactor system was employed to synthesize metal oxide nanocrystals in aqueous solution. Assembly of nanocrystals is considered one of the most...

Leveraging the Food-Energy-Water Nexus for Planet Resilience

Creator:: Steadman, Casey L.
Abstract:: We have sufficient evidence that our historical management of natural resources is not sustainable. Food production is stagnating or declining. Nonrenewable energy sources on which the energy sector has historically depended are being rapidly depleted. Water resources, for which the energy and food sectors compete, are being depleted and impaired....

Mathematical and Experimental Approaches for Designing Less Toxic Cryopreservation Methods

Creator:: Warner, Ross M.
Abstract:: Successful cryopreservation of all biological specimens would have an untold positive impact on medicine and scientific research. However, cryopreservation of the most complex biological specimens, such as tissues and organs, remains elusive. Vitrification, or ice-free cryopreservation, is promising for cryopreservation of complex specimens. The biggest challenge, though, is the toxicity...
