  • The absolute measurement of electrical capacities 

    Shackelford, Benjamin Estill, b. 1891 (University of Missouri, 1913)
    Of the various methods in use at the present time for the absolute measurement of electrical capacities in electromagnetic units, none give the satisfaction desired. Only two of these methods are in common use and they ...
  • The acceleration of gravity : an absolute determination with a Kater's pendulum for Columbia, Missouri 

    Walters, Francis Marion, Jr. (University of Missouri, 1913)
    Galileo Galilei (1564-1642) was the first to question the assertion of Aristotle that bodies fall with velocities proportional to their weights. He dramatically refuted this Aristotelian doctrine by dropping from the Tower ...
  • Airy beam for three-dimensional optical imaging 

    Wang, Fengfei (University of Missouri--Columbia, 2017)
    [ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Airy beam is a self-sustained light beam that propagates in free space along a parabolic trajectory with a constant lateral acceleration. It is a ...
  • The [alpha]-rays and the [alpha]-particle : a study of ionization and allied phenomena produced by [alpha]-rays 

    Briggs, C. A. (Clark Arthur), b. 1883 (University of Missouri, 1910)
    As a result of experiments by M. Henri Beoquerel in 1896 we now know a certain class of chemical elements as Radio-active. A radio-active body gives off radiations that have the following effects: 1) they will affect a ...
  • Annealing-dependent phenomena in Ga₁[-x]Mn[x]As 

    Kirby, Brian J., 1977- (University of Missouri--Columbia, 2004)
    There has been a great deal of recent research interest in the development of "spintronics" technology. Many potential spintronic devices will require a "spin injector" capable of producing a spin-polarized current. In ...
  • Carbon stars and silicon carbide 

    Corman, Adrian, 1979- (University of Missouri--Columbia, 2010)
    Stars between about 0.8 and 8 times the mass of the Sun will eventually evolve become asymptotic giant branch (AGB) stars, where they pulsate and throw off mass from their atmospheres, forming dust shells in the space ...
  • Cathode disintegration 

    Jones, Ira (University of Missouri, 1911)
    It has been pointed out that the cathode disintegration depends upon the gas present as well as upon the metal of which the cathode is composed. Hence it was thought interesting to investigate whether the gas in which the ...
  • Cell mechanics studied using atomic force microscopy 

    Sun, Mingzhai, 1979- (University of Missouri--Columbia, 2008)
    Cholesterol plays an indispensable role in regulating the properties of the cell membrane. In particular, lipid rafts, specific membrane domains, which are thought to be required for a number of cell functions, such as ...
  • Charge-transfer and other excitonic state in conjugated polymer : fullerene blends-implication in photovoltaics 

    Moghe, Dhanashree ([University of Missouri--Columbia], 2014)
    Over the last few decades there has been tremendous progress in organic photovoltaics (OPVs), with efficiencies reaching over 10%. Still, many factors including the origin and the dynamics of charge carrier involved are ...
  • Collective charge- and spin-density excitations in semiconductor quantum wells 

    Karimi, Shahrzad (University of Missouri--Columbia, 2017)
    Quasi-two-dimensional (2D) systems, such as an electron gas confined in a quantum well, are important model systems for many-body theories, and we are interested in studying collective excitations in such systems using a ...
  • A comprehensive report on preparing and analyzing adsorptive materials suitable for hydrogen and methane storage 

    Rash, Tyler Austin (University of Missouri--Columbia, 2014)
    Development of low-pressure, high-capacity adsorbent based storage technology for methane, natural gas, and hydrogen as fuel for advanced transportation is necessary in order to address the temperature, pressure, weight, ...
  • Computational and theoretical study of water and lipid dynamics in biomolecular systems 

    Jhuma, Das, 1980- (University of Missouri--Columbia, 2010)
    This Ph.D. thesis describes three research projects in theoretical and computational biophysics aimed at studying the dynamics of water and lipid molecules in two distinct biomolecular systems. In the first project the ...
  • Development and analysis of ZnO-based semiconductor photodetectors for UV detection 

    Li, Linghui, 1976- (University of Missouri--Columbia, 2010)
    The objective of this thesis is to develop ZnO-based semiconductor photodetectors for UV detection with low dark current, high responsivity, and fast response time. To achieve this objective, an understanding of carrier ...
  • Dust formation and evolution around carbon stars 

    Groom, Hannah (University of Missouri--Columbia, 2018)
    Evolved intermediate-mass stars with carbon-to-oxygen ratios (C/O) above unity are known as carbon stars. Carbon stars are surrounded by dust shells dominated by carbon (C) and silicon carbide (SiC) grains. These SiC grains ...
  • Effect of temperature, density, and strength of electric current on the spectra of gases 

    Greene, Charles Arthur (University of Missouri, 1901)
    Light may be defined as that vibration of the ether which, acting on the organ of sight, produces in us the sensation of vision. But when, on reflection, we realize that the sense of sight is the most useful of all man's ...
  • Effects of spin current in ferromagnets 

    He, Jiexuan, 1980- (University of Missouri--Columbia, 2008)

  • Electrolytic rectifiers 

    Brous, Bertrand Caley (University of Missouri, 1912)
