In Pursuit of Extraordinarily Twisted Acenes
(2015-05-26)
Longitudinally twisted acenes are a topologically interesting class of polycyclic aromatic hydrocarbons (PAHs), and it could be argued that they have quite beautiful chemical structures, too. X-ray crystal analysis of many ...
Positron interactions with oriented polymers and with chiral quartz crystals
(University of Missouri--Kansas City, 2017)
Positron annihilation in various materials has been applied to characterize
microstructure for decades. In this work, PALS was used to study material nanostructure,
with a focus on the size and density of free volume ...
Photoemission Spectroscopy Studies of New Topological Insulator Materials
(2015-08-04)
As the size of a solid shrinks, the ratio of surface area to bulk volume grows and
surface effects become more important. In a world where technologies advance with the
shrinking size of electronic devices, one phase of ...
Effects of pressure and temperature on the yield strength of tantalum and rhenium
(2013)
The effects of pressure and temperature on the yield strength of tantalum and
the effects of pressure on the yield strength of rhenium were investigated using ruby
fluorescence. A new Raman system with a motorized stage ...
Mathematical Analysis of Compressive/Tensile Molecular and Nuclear Structures
(2015-06-19)
Mathematical analysis in chemistry is a fascinating and critical tool to explain
experimental observations. In this dissertation, mathematical methods to present
chemical bonding and other structures for many-particle ...
