Item A relation between electroconductivity and liquid-liquid equilibrium in ternary systems(Texas Tech University, 1964-08) Fox, Jerry VanNot availableItem Examining correlations of electrostatic discharge sensitivity and electrical conductivity of composite energetic materials(2012-05) Weir, Chelsea; Pantoya, Michelle; Chaudhuri, Jharna; Dallas, Timothy E. J.; Ekwaro-Osire, StephenComposite energetic material response to electrical stimuli was investigated and a correlation between the composite’s electrical conductivity and ignition sensitivity was examined. The composites consisted of micrometer particle aluminum combined with another metal, metal oxide, or fluoropolymer. Of the nine tested mixtures, aluminum and copper oxide was the only mixture to ignite by electrostatic discharge (ESD) with minimum ignition energy of 25 mJ and an electrical conductivity of 3.45 nS. In an ESD event, energy is delivered through the spark and through joule heating of the particles. For this reason, thermal ignition was also examined using a hot wire. This study showed a similar trend in minimum ignition energy for ignition triggered by a discharged spark compared with ignition triggered by a thermal hot wire source. However, a discharged spark concentrates energy locally supplying greater power for ignition. This study begins to explore critical parameters influencing electrostatic discharge ignition, specifically electrical resistivity and conductivity of particulate mixtures.Item Study of energy band diagrams of Group III-Nitride heterostructures(Texas Tech University, 2003-12) Gnanaeswaran, SendillNot availableItem Superstructure conductivity in the digital micromirror device (DMDtm)(Texas Tech University, 2004-12) Whitby, Amisha MishayThis paper investigates the distribution of conductivity in the DMD and how process anomalies can lead to a nonlinear response In addition, statistical methods will be used to prove that these process anomalies are present all wafers and all die. Finally, simulations based test data will be used to show how the impact of such nonlinearities affect the operating margin of the DMD.Item Transverse-ultrasonic-attenuation determination of the energy gap between the normal and superconducting states of zinc.(Texas Tech University, 1975-05) Breashears, Eddie HearlNot availableItem Use of Electrical Conductivity in Evaluating Cottonseed Quality(Texas Tech University, 1980-05) Hinton, Harold RayNot Available.
