The absolute measurement of electrical capacities
(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
(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 /
(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
(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
(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 ... -
Applications of model systems to explore exchange-correlation effects in density-functional theory
(University of Missouri--Columbia, 2020)Density-functional theory (DFT), in its various forms, has become a near ubiquitous form of theoretical research used to benchmark and prototype solutions to many finite and extended state system. This is largely because ... -
Bridging biochemical activities with conformational dynamics observed in atomic force microscopy
(University of Missouri--Columbia, 2020)This dissertation was written with the intention to provide future investigators with general information sufficient to start their own investigations in biological atomic force microscopy. It is noted that background ... -
Carbon stars and silicon carbide
(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
(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
(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
([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
(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
(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
(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 ... -
Design, fabrication, and testing of a bioprinted nerve graft
(University of Missouri--Columbia, 2016)Injuries to nerves vary in their consequences, from weakened sensation and motor function to partial or complete paralysis. In the latter case, affecting about twenty thousand Americans yearly, the injury is debilitating ... -
Determination of saturated film densities and volumes for adsorbed hydrogen, and application to the calculation of the enthalpy of adsorption at room temperature
(University of Missouri--Columbia, 2018)The development of high-performance materials for hydrogen storage by physical adsorption requires understanding of detailed microscopic properties of the adsorbed film. In this work, we show that adsorbed hydrogen films ... -
Development and analysis of ZnO-based semiconductor photodetectors for UV detection
(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 ... -
Donor-acceptor copolymers and sol-gel processable zinc oxide for thin film transistors and hybrid photodetectors
(University of Missouri--Columbia, 2019)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Organic semiconductors have been gaining attention both in research and commercial development for electronic devices due to their low manufacturing ... -
Dust formation and evolution around carbon stars
(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
(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 ...
