| 1 |  | Lithium1.3Aluminum0.3Titanium1.7Phosphate as a solid state Li-ion conductor: Issues with microcracking and stability in aqueous solutions | Jackman, Spencer D. | Inorganic chemistry; Materials science | Lithium aluminum titanium phosphate (LATP) with formula Li1.3Al0.3Ti1.7(PO4)3 was analyzed and tested to better understand its applicability as a solid state ion conducting ceramic material for electrochemical applications. Sintered samples were obtained from Ceramatec, Inc. in Salt Lake City and ch... | 2012 |
| 2 |  | Increasing the stability and efficiency of bio-solar cell electrodes using reactivbe oxygen species scavengers and redox polymer immobilization | Stephanz, Megan E. | Engineering; Materials science | Global energy requirements are increasing with time. While fossil fuels can be relied upon for several more centuries, they would produce vast amounts of carbon dioxide. This undesirable fact makes renewable options like bio-solar cells, which are clean, inexpensive, and take advantage of abundant ... | 2017 |
| 3 |  | Dielectric breakdown of polycrystalline alumina: a weakest-link failure analysis | Block, Benjamin | Alumina; Dielectric; Extreme value; Laplace; Weakest-Link; Weibull; Materials science | The effects of varying electrode geometry (ball and ring) and size (radius), dielectric media (castor oil and Diala® oil), specimen thickness, and concentration of defects on the dielectric breakdown strength of commercial-grade alumina and high-purity fine-grained (HPFG) alumina were investigated.... | 2013-08 |
| 4 |  | Effects of antimony surfactanton indium gallium nitride grown by organometallic vapor phase epitaxy | Merrell, Jason Lawrence | Antimony; Indium Gallium Nitride; Organometallic vapor phase epitaxy; Surfactant; Materials science | This work reviews the fundamentals of InGaN materials and of surfactant effects in surfactant-mediated heteroepitaxial growth. The basic surface processes and possible surfactant mechanisms are presented. These principles are then applied to a study of the effects of Sb surfactant on InGaN grown by ... | 2012-12 |
| 5 |  | Evaluation of ternary blended cements for use in transportation concrete structures | Gilliland, Amanda Louise | Blended cement; Cement; Concrete; Fly ash; Slag; Ternary; Transportation structures; Concrete structures; Civil engineering; Materials science | This thesis investigates the use of ternary blended cement concrete mixtures for transportation structures. The study documents technical properties of three concrete mixtures used in federally funded transportation projects in Utah, Kansas, and Michigan that used ternary blended cement concrete mi... | 2011-05 |
| 6 |  | The effect of electrode surface topography on the structure and differential capacitance of the electric double layer capacitor | Cao, Liulei | Capacitor; Differential capacitance; Electric double layer; Surface topography; Physical chemistry; Energy; Materials science | Molecular dynamics simulations were conducted to study the structure and differential capacitance of the electric double layer capacitor by varying electrode topography. Studying the dependence of structure and differential capacitance (DC) on electrode potential is a central point of electric doubl... | 2011-08 |
| 7 |  | Energy balance in solid-oxide fuel assisted electrolyzer cell modules | Butler, Bruce Jacob | Electrolyzer; Fuel assisted; Hydrogen; Hydrogen generation; Hydrogen production; Solid oxide; Chemical engineering; Mechanical engineering; Materials science | High temperature electrolysis of water is a well-known method of extracting hydrogen, and has reduced electrical potential requirements when compared to low temperature electrolysis. The reduction in electrical energy cost is useful when a source of high temperature steam (or sufficient waste heat) ... | 2010-08 |
| 8 |  | Effects of angled stitch reinforcement on foam core sandwich structures | Sok, Thien | Aerospace engineering; Mechanical engineering; Materials science | TThe mechanical effects of varying stitch angles in stitched sandwich structures were investigated. A repeatable fabrication method was developed for stitching Kevlar yarn through sandwich panels of polyurethane foam and dry woven carbon fiber facesheets. Unstitched, 30°, 45°, 60°, and 90° stitc... | 2010-12 |
