Modeling and control studies of a magnetically-staged fluidized bed

Creator:: Al-Zahrani, Abdulrahim
Abstract:: A column which contains a series of three fluidized beds for counter-current contacting of solid particles with a gas stream has been studied. Successful, independent control of solids holdup on each stage has been achieved by manipulating the field of a magnetic distributor-downcomer on each stage. Two methods to manipulate...

Continuous and rapid synthesis of nanoclusters and nanocrystals using scalable microstructured reactors

Creator:: Jin, Hyung Dae
Abstract:: Recent advances in nanocrystalline materials production are expected to impact the development of next generation low-cost and/or high efficiency solar cells. For example, semiconductor nanocrystal inks are used to lower the fabrication cost of the absorber layers of the solar cells. In addition, some quantum confined nanocrystals display electron-hole pair...

Aging and performance evaluation of marine antifouling coatings

Creator:: Bunn, Malachi D.
Abstract:: Marine biofouling is a major problem in many industries. Shipping has been afflicted with reduced vessel speed and hindered maneuverability due to organisms attaching since the dawn of sailing. To date, the primary method developed to prevent fouling is the application of biocide laden coatings with various release mechanisms. Mass...

Nonthermal Plasma Microreaction Engineering for Gas and Liquid Processing

Creator:: Pommerenck, Justin
Abstract:: Atmospheric pressure plasma is non-thermal at millimeter to micrometer separations. It represents an alternative low exergy initiator of many chemical reactions. In many instances heat, light or sound are not efficient providers of the necessary energy to overcome chemical activation barriers. The focus of this research is applying dc nonthermal...

Enhancement and modeling of cryogenic solid-state hydrogen storage systems with a novel microchannel thermal management device

Creator:: Loeb, Christopher S.
Abstract:: Compact storage systems demonstrating increased hydrogen storage capacity are the key to advancing the growth of the hydrogen economy throughout the world and reducing the global dependence on fossil fuels for transportation. The use of highly porous adsorbent materials for reversible hydrogen storage is a promising pathway towards achieving storage...

Roles of gas and solid components in the direct nitridation of silicon

Creator:: Pavarajarn, Varong
Abstract:: The factors influencing the direct nitridation of silicon, including the effects of the native oxide layer covering the surface of silicon, the effects of hydrogen contained in the nitridation gas and the catalytic effects of metals added to the raw material silicon, were investigated, using a tubular flow reactor and...

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....
