The reversibility of the adsorption of methane-methyl mercaptan mixtures in nanoporous carbon
(University of Missouri--Columbia, 2011)
Methane is the main constituent of natural gas (NG). As fuel for vehicular applications NG requires sorbents that allow efficient, reversible and safe storage at room temperature and moderate pressure. To enable easy human ...
Percolative effects in quantum critical systems : how magnetic clusters shape the response at low temperatures
(University of Missouri--Columbia, 2011)
We have investigated the link between cluster morphology and non-Fermi liquid behavior in the bulk properties of Ce(Ru1-xFex)2Ge2, a prototypical quantum critical system that has been driven to criticality through chemical ...
Ion dependent stability of RNA three-way junction and DNA triple helices
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Nucleic acids are critical for regulation of gene expression. Because nucleic acid molecules are highly charged, the folding of nucleic acids involves ...
Investigations of novel hydrogen adsorption phenomena
(University of Missouri--Columbia, 2011)
For convenient use of energy, it is common to use chemical potential energy stored in a fuel. To reduce pollution, a desirable fuel is molecular hydrogen, whose only byproduct is water vapor. However, there are still many ...
Extremely extended dust shells around evolved intermediate mass stars: probing mass loss histories, thermal pulses and stellar evolution
(University of Missouri--Columbia, 2011)
Intermediate mass stars ($0.8 - 8 solar masses), at the asymptotic giant branch phase (AGB) suffer intensive mass loss, which leads to the formation of a circumstellar shell (s) of gas and dust in their circumstellar ...
Using infrared observations of circumstellar dust around evolved stars to test dust formation hypothesis
(University of Missouri--Columbia, 2011)
Asymptotic Giant Branch (AGB) stars are evolved, low to intermediate mass (0.8-8M[circle dot operator}) stars. These stars lose a significant fraction of their mass through stellar pulsation. As a result, they are surrounded ...
X-ray diffraction studies on the Pb/Si(111) system
(University of Missouri--Columbia, 2011)
This dissertation investigates the structure of the Pb wetting layer on the Si(111)7x7 using X-ray diffraction techniques. It was found that the wetting layer shows a surprising kinetic behavior within the structure over ...
