Investigating peptide-lipid interactions at single molecule level
(University of Missouri--Columbia, 2017)
, for example, aid the design of more compatible and effective medicine to target specific cells. We developed a physical technique to study such interactions and investigated the interactions between small portions of a model protein with different types...
An informal history of astronomy at the University of Missouri-Columbia
(Dept. of Physics and Astronomy, University of Missouri - Columbia,, 1981)
Computational studies of methane adsorption in nanoporous carbon
(University of Missouri--Columbia, 2012)
In this thesis we have completed computational studies using Grand Canonical Monte Carlo on the adsorption of methane into a graphitic nanoporous adsorbent with slit-shaped pores. Simulations were done at a temperature of ...
Hydrogen adsorption studies of engineered and chemically modified activated carbons
(University of Missouri--Columbia, 2012)
My research focuses on the production of boron-doped activated carbons and the evaluation of their adsorption and structural characteristics. Boron-doped activated carbons have been produced using a process involving 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 ...
Optical-faint compact radio sources
(University of Missouri--Columbia, 2017)
This work investigates a population of bright, compact radio sources that are very faint in optical, which has never been studied before in a comprehensive manner. The sample consists of 135 radio sources selected from the ...
Developing molecular docking methods to model protein interactions
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In many cellular processes, proteins carry out their functions through interacting with other molecules, such as small compounds (i.e. ligands), peptides ...
3-D Dynamics of Interactions between Stellar Winds and the Interstellar Medium as Seen by AKARI and Spitzer
(2009)
Recent far-infrared mapping of mass-losing stars by the AKARI Infrared Astronomy Satellite and Spitzer Space Telescope have suggested that far-infrared bow shock structures are probably ubiquitous around these masslosing stars, especially when...
Watching biological nanomotors at work : insights from single-molecule studies
(University of Missouri--Columbia, 2017)
Recent decades have seen several complimentary biophysics tools emerge to study single protein macromolecules. Most of these techniques use glass as a specimen support. The atomic force microscope, a vital tool in biophysics ...
Reference frames and equations of motion in the first PPN approximation of scaler-tensor and vector-tensor theories of gravity
(University of Missouri--Columbia, 2006)
Post-Newtonian relativistic theory of astronomical reference frames based on Einstein's general theory of relativity was adopted by the General Assembly of the International Astronomical Union in 2000. This theory is ...
Neutron interferometry in a rotating frame of reference
(American Physical Society, 1988)
The physical basis for the description of phenomena by a rotating observer is investigated. A simple, yet tentative, extension of the hypothesis of locality is used to determine the interference phase shift induced by the rotation of a neutron...
Physics-based predictions of RNA loop stability and structures
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] RNA (ribonucleic acid) molecules play a variety of crucial roles in cellular functions at the level of transcription, translation and gene regulation. ...
Effects of spin current in ferromagnets
(University of Missouri--Columbia, 2008)
are performed to verify our analytical results. Simulation results also reveal the physical origin of many phenomena observed in experiments. The direct interaction between conducting electrons and local moments polarizes the electron spins, and at the same time...
Quantized massive spin 1/2 fields on static spherically symmetric wormhole spacetimes
(University of Missouri--Columbia, 2012)
of approximations are used in the computation in order to make the problem mathematically tractable; but it is not clear under what physical circumstances these approximations could hold. Besides, the cases that I investigated turned out to involve unphysically...
Stability of pulsar rotational and orbital periods
(arXiv, 2009)
Millisecond and binary pulsars are the most stable astronomical standards of frequency. They can be applied to solving a number of problems in astronomy and time-keeping metrology including the search for a stochastic gravitational wave background...
Theoretical and in silico modeling of biological systems : from protein structure prediction to cellular dynamics
(University of Missouri--Columbia, 2009)
This thesis describes four distinct studies (involving a variety of concepts and methods from the physical sciences) of complex biological systems and processes that cover a wide range of time and length scales (extending from the molecular...
Investigations of novel hydrogen adsorption phenomena
(University of Missouri--Columbia, 2011)
proposed method is via physical adsorption to some high surface area material. However, current materials are still far from meeting Department of Energy goals. This work discusses improvements to some traditionally less reliable techniques used...
Low dielectric constant-based organic field-effect transistors and metal-insulator-semiconductor capacitors
(University of Missouri--Columbia, 2012)
-linked PVP (c-PVP) gate dielectrics. A physical method - matrix assisted pulsed laser evaporation (MAPLE) - of fabricating all-polymer field-effect transistors and MIS capacitors that circumvents inherent polymer dissolution and solvent-selectivity problems...
Massive-Star Supernovae as Major Dust Factories
(arXiv, 2006)
We present late-time optical and mid-infrared observations of the Type-II supernova 2003gd in NGC 628. Mid-infrared excesses consistent with cooling dust in the ejecta are observed 499-678 days after outburst, and are ...
Small-scale structures in planetary nebulae
(University of Missouri--Columbia, 2017)
of stars is born. Molecular hydrogen (H[subscript 2]) was used a tracer for molecular emission and its excitation properties used as a probe of shock physics. Previous studies of several planetary nebulae have indicated a relationship between molecular...
