The production, applications and economic study of activated carbon for large scale production including an educational study on undergraduate laboratory modules
(University of Missouri--Columbia, 2010)
The production of activated carbon was evaluated using a biomass feed stock, corn cobs, as a precursor. The importance of the carbonization process and activation process are discussed and how nanopores and its unique surface chemistry allow...
Bismuth impurity effects on copper: examining embrittlement in immiscible binary metallic systems
(University of Missouri--Columbia, 2013)
that the interfaces between each of the metallic components to be sharp and well-defined. This resembles a picture painted in undergraduate chemistry courses examining aqueous/organic phase separations. In binary metallic melts involving immiscible components much...
Failure analysis of green ceramic bodies during thermal debinding
(University of Missouri--Columbia, 2009)
formation, which arises from excessive stresses, plays a major role in determining the duration of the heating cycle. This thesis presents failure behavior of green MLCs as a function of changing body size and heating rate. This is then used to design rapid...
Technology for restarting molten salt nuclear fuel chemistry at MU
(University of Missouri--Columbia, 2011)
Nuclear fuel reprocessing is a responsible choice for the continued expansion of a secure, safe and clean source of energy. While the classical method for recycling nuclear fuel is an aqueous liquid-liquid extraction, the ...
Use of enzymes to produce soy-based polyol for polyurethane
(University of Missouri--Columbia, 2006)
required to preserve enzyme activity. The enzyme technology encourages the development of "green chemistry" and "sustainability" for urethane consumers. The results conclusively demonstrated that selective enzymes can synthesize improved soy-based polyols...
Development of a combined dilatometer and mass spectrometer system for studying gas phase chemistry and kinetics during sintering
(University of Missouri--Columbia, 2010)
so than numeric integration when noise is present in the data. Additionally, if an equation for the mechanism is known, the approximation can be substituted for the integral so that the full equation can be mathematically manipulated to facilitate...
Enhancing methanol electro-oxidation by double oxide incorporation with platinum on carbon nanotubes
(University of Missouri--Columbia, 2016)
Electro-oxidation of methanol was investigated on platinum catalyst supported on a double oxide nanocomposite support of tin oxide and carbon-doped titanium dioxide. The Pt-SnO2-C-/CNTs electro catalyst demonstrated about ...
Developing a novel method for making metal oxide nanocoatings for electrocatalysis applications
(University of Missouri--Columbia, 2020)

Novel biomaterials for controlled immunomodulatory drug delivery
(University of Missouri--Columbia, 2022)
With the success of solid organ transplantation, a next generation approach has been developed known as vascularized composite allografts which requires the transplantation of a whole functional unit comprised of many ...
Nanoporous carbon from corn cobs and its application
(University of Missouri--Columbia, 2007)
Chemical activation of corn cobs using phosphoric acid or potassium hydroxide can lead to nanoporous carbon having surface area in excess of 3800 m²/g and pore volume of 2.5cc/g. Dried, crushed, corn cobs were carbonized ...
