Neutron diffraction and quasielastic neutron scattering studies of films of N-alkanes and a branched alkane adsorbed on graphite
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Neutron diffraction and quasielastic neutron scattering have been used to study the structure and dynamics of films of n-alkanes and of a branched ...
Properties of low-dimensional systems
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In this work we study the equilibrium properties of systems in two-dimensions, and the effects that discrete symmetry, space dimensionality, character ...
Theory of lattice effects on magnetic interactions in solids
(University of Missouri--Columbia, 2005)
This dissertation focuses on studying the effect of lattice distortions on the magnetic properties of nickelates and manganites. These two families of materials have great potential in industrial applications in the fields ...
Nonlinear intersubband dynamics in semiconductor nanostructures
(University of Missouri--Columbia, 2007)
The intersubband (ISB) dynamics of conduction electrons in semiconductor quantum wells exhibits a variety of interesting and potentially useful nonlinear phenomena. In this work we present three different formalisms which ...
On the astromineralogy of the 13 [mu]m feature in the spectra of oxygen-rich AGB stars
(University of Missouri--Columbia, 2006)
Approximately half the oxygen-rich AGB stars to be investigated spectroscopically exhibit a feature at 13 [mu]. The carrier of this feature has not yet been unequivocally identified, but has been attributed to various dust ...
The interplay of physical and molecular determinants in limb and cardiac cushion morphogenesis
(University of Missouri--Columbia, 2007)
In an effort to investigate the interplay between molecular determinants and biomechanical properties during early embryonic development we have investigated two separate but similar morphogenetic processes: limb morphogenesis ...
Multiscale modeling of biomolecular systems
(University of Missouri--Columbia, 2007)
Studies of structure-function relationships in biomolecular systems require to follow nanometersize systems on time scales spanning from pico- to micro-seconds, while maintaining atomic scale spatial resolution in all-atom ...
General relativistic theory of light propagation in the field of gravitational multipoles
(University of Missouri--Columbia, 2007)
We consider propagation of electromagnetic signals through the time-dependent gravitational field of an isolated astronomical system emitting gravitational waves. The system is assumed to possess multipole moments of ...
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 ...
Raman scattering studies and charge transport in polyfluorenes
(University of Missouri--Columbia, 2007)
Blue-emitting polyfluorenes (PFs) have emerged as especially attractive [pi] conjugated polymers (CP) due to their strong blue emission and excellent electronic properties and thus great prospects for device applications. ...
Theory of the two-dimensional airy electron gas: Hartee-Fock and density-functional studies
(University of Missouri--Columbia, 2005)
Transition-metal oxides are one of the most interesting and heavily researched materials in condensed matter physics for the range of unique properties they exhibit, like colossal magneto resistance and high temperature ...
Spin angular momentum transfer in magnetic nanostructure
(University of Missouri--Columbia, 2007)
Spin angular momentum transfer, or spin transfer, is a short notion of the transfer of spin angular momentum between the spin polarized current and the magnetization of ferromagnetic condensates. Spin transfer effect in ...
Theory of photo-induced ferro-magnetism in dilute magnetic semiconductors
(University of Missouri--Columbia, 2006)
This thesis is a theoretical study of photo-induced ferro-magnetism in dilute magnetic semiconductors. When light is incident on these systems, electrons and holes are created across the band gap. These particles interact ...
Pressure dependence of the luminescence and Raman modes in polyfluorene
(University of Missouri--Columbia, 2005)
I present a study of the optical properties of poly-para-phenylene and three different side-chain substituted polyfluorene polymers. I present an analysis of the Raman spectra under hydrostatic pressures for three ...
Physical mechanisms of cell rearrangements: from tissue liquidity to artificial organ structures
(University of Missouri--Columbia, 2006)
This research presents a study of biological self-assembly in which we create 3D living functional tissue structures by exploiting the self organizing capacity of cells and tissues. Tissues composed of adhesive and motile ...
Mechanical properties of complex biological systems using AFM-based force spectroscopy
(University of Missouri--Columbia, 2005)
An atomic force microscope (AFM) was designed and built to study the mechanical properties of small collagen fibrils and the plasma membrane of living cells. Collagen is a major component of bone, skin and connective ...
