Asymmetric Positron Annihilation in Chiral Tartrate and Tartaric Acid Crystals
(University of Missouri–Kansas City, 2015)
Positron annihilation lifetime spectroscopy (PALS) has been used to study the interactions of positrons with chiral tartaric acids and tartrates. Differences in lifetimes of and its intensity I2 were compared between large ...
Mathematical Analysis of Compressive/Tensile Molecular and Nuclear Structures
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 ...
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 ...
