Local quantities and topological invariants of hermitian matrices
(University of Missouri--Columbia, 2018)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This thesis contains developments of two related topics, both born out of a desire to understand the electronic eigenstates of crystal lattices with ... -
Emergent properties in the artificial magnetic honeycomb lattice of ultra-small elements
(University of Missouri--Columbia, 2018)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The artificial magnetic honeycomb lattice is expected to manifest a broad and tunable range of novel magnetic phenomena associated with the geometric ... -
Structural and chemical characterization of modified graphenes for hydrogen storage
(University of Missouri--Columbia, 2018)The automotive industry is already showing signs of moving beyond a century long dependence on petroleum. The tens of billions of dollars in the electric vehicle (EV) consumer market are a powerful demonstration of this ... -
X-Ray scattering at the periphery : forbidden bragg reflections and silicon nanowire arrays
(University of Missouri--Columbia, 2018)In this work, we developed two separate unconventional X-ray scattering techniques that enable us to extract novel information from distinct systems at disparate length scales. We examine the formation of Si nanowire (SiNW) ... -
Spectropolarimetric constraints on interstellar grain models
(University of Missouri--Columbia, 2018)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] It is now well recognized that the interstellar medium acts as an efficient polarizer of electromagnetic radiation, resulting in the partial plane ... -
Single-molecule observation of nucleotide induced conformational changes in basal SecA-ATP hydrolysis
(2018)SecA is the critical adenosine triphosphatase that drives preprotein transport through the translocon, SecYEG, in Escherichia coli. This process is thought to be regulated by conformational changes of specific domains of ... -
Synergy of wide-field infrared survey explorer (WISE) and the Sloan Digital Sky Survey in Stripe 82
(University of Missouri--Columbia, 2018)In this dissertation, I aim to study the evolution of galaxies over the last 6 Gyr by measuring the growth of the global stellar mass density (GSMD) since z = 0.8. My work combines the datasets from two very large surveys, ... -
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 ... -
Neutron scattering studies of water diffusion near the interface of model cell membranes
(University of Missouri--Columbia, 2018)Membrane proteins represent a significant frontier in structural biology they are ubiquitous in nature and perform a variety of tasks that help govern cellular activity. Their structure, insertion mechanisms, and function ... -
Exploring star formation in high-mass galaxies in the low-z universe
(University of Missouri--Columbia, 2018)We present a quantitative analysis of high-mass, low-z galaxies in order to investigate the 'downsizing' scenario of galaxy evolution. High-mass, low-z galaxies with ongoing star formation, antithetical to the 'downsizing' ... -
Galaxy evolution as seen by Herschel
(University of Missouri--Columbia, 2018)The unprecedented Herschel data have revolutionized our view of the IR universe, providing new insights to galaxy formation and evolution. However, the Herschel data are still far away from being fully explored, mainly due ... -
Self-assembled peptide nanostructures for electrical, optical, and magnetic applications
(University of Missouri--Columbia, 2018)Bio-nanotechnology has become a widespread exciting field of research as the basic biological structure of bio-inspired materials and nanotechnology share the common length scale. Bio-nanotechnology, which is mainly based ... -
Activated carbon monoliths for methane storage : abstract submitted for the MAR12 Meeting of The American Physical Society
(2011)Abstract submitted for the MAR12 Meeting of The American Physical Society: The use of adsorbent storage media for natural gas (methane) vehicles allows for the use of non-cylindrical tanks due to the decreased pressure at ... -
Glass slides and coverslips for microscopy : protocol
(2015)"It is important that the glass slides and coverslips used in microscopy experiments be extremely clean. Although commercially available coverslips and slides look clean, especially when out of a new box, they may have a ... -
Optimizing the tissue engineering of tubular organ structures by bio-printing
(University of Missouri--Columbia, 2014)Tissue engineering and regenerative medicine may help to save people’s lives by fabricating new organs. Towards this goal our objective is to optimize the conditions for cells to self assemble into functional structures, ... -
Subsurface structure & morphology : Epitaxial metal film growth studied by in situ X-ray scattering
(University of Missouri--Columbia, 2014)The existence of missing material (vacancies) below the exposed surface was deduced from deposition-angle-dependent experimental evidence. Due to a lack of experimental evidence, theoretical film growth models have largely ... -
Glass is a viable substrate for precision force microscopy of membrane proteins
(2015)Though ubiquitous in optical microscopy, glass has long been overlooked as a specimen supporting surface for high resolution atomic force microscopy (AFM) investigations due to its roughness. Using bacteriorhodopsin from ... -
Glass is a viable substrate for atomic force microscopy of membrane proteins : abstract submitted for the PSF13 Meeting of the American Physical Society
(2013)Abstract submitted for the PSF13 Meeting of The American Physical Society: Since its invention in the mid-1980s, the atomic force microscope (AFM) has become an invaluable complementary tool for studying membrane proteins ... -
Glass : a multi-platform specimen supporting substrate for precision single molecule studies of membrane proteins : [abstract]
(2015)Abstract in program book: High resolution (~ 1 nm lateral resolution) biological AFM imaging has been carried out almost exclusively using freshly cleaved mica as a specimen supporting surface, but mica suffers from a ... -
Glass is a viable substrate for atomic force microscopy of membrane proteins : [abstract]
(2014)Abstract in program book: Since its invention in the mid-1980s, the atomic force microscope (AFM) has become an invaluable complementary tool for studying membrane proteins in near-native environments. Historically, mica ...
