Effects of a combined supercritical extraction/thermal cycle on binder removal cycle time, yield, residual carbon, and defect formation in multilayer ceramic capacitors
(University of Missouri--Columbia, 2010)
In this work, a combined cycle consisting of a supercritical extraction cycle (SCE) followed by a thermal cycle (TC), was used to remove binder from green multilayer ceramic capacitors. The dielectric was barium titanate ...
Large-scale fabrication of SiC nanofibers and plasma interface engineering of polymer nanocomposites and dental composite restoration
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] SiC nanofibers in gram-scale per batch were synthesized by chemical vapor deposition. A systematic comparison of different sized graphite and multi-walled ...
Nanomaterial surface modification for heat-transfer nanofluid and electrochemical DNA biosensor development
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Low-temperature plasma polymerization was performed to coat the individual nanomaterial not only for better suspension but also for thermal conductivity ...
Gas phase conversion of sugars to C3 chemicals
(University of Missouri--Columbia, 2008)
The limited fossil oil reserve, fast-rising crude oil price and increasing environmental concerns make scientists and researchers give a serious look at biomass as feed stocks to produce chemicals and fuels. Five chapters ...
Validation and insight into a novel packed-bed electrode flow battery architecture
(University of Missouri--Columbia, 2010)
In order to improve upon current flow battery technology and to obtain higher specific energies, a novel packed-bed electrode flow battery (PBEFB) is proposed. The validation of the use of packed-bed electrodes in a flow ...
The continuous supercritical water gasification of spirulina and the use of a positive displacement feeding system
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] A factorial experiment was designed and conducted to explore the effect of three variables, concentration, temperature, and residence time, on two ...
Investigation of supercritical fluids for use in biomass processing & carbon recycling
(University of Missouri--Columbia, 2012)
An apparatus was built in the Mizzou Carbon Recycling Center to explore the continuous thermochemical conversion of biomass and model compounds in supercritical water. The apparatus was used to investigate gasification or ...
Chemical modifications to produce soy-based polyols
(University of Missouri--Columbia, 2009)
This project comprises several chemical routes to produce soy-based polyols for future use in polyurethane foam applications. Soybean oil was polymerized by heat and catalyst to increase molecular weight, and viscosity for ...
Electrospinning polyampholyte nanofiber membranes
(University of Missouri--Columbia, 2014)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The elimination of nonspecific protein adsorption is an important challenge in many biomaterial applications. To address this issue, numerous nonfouling ...
Modification of thin film composite (TFC) membrane by incorporation with copper nanoparticles (Cu-NPs) for antibacterial properties
