Description:: Understanding organization of soft materials on mesoscopic and nanoscopic scales is importantfor materials design. In this regard, non-van der Waals interactions such as hydrogen bonding and electrostatic interactions offer great opportunities due to the richness and diversity in morphological structures they produce. The primary reason for this is that these...

Description:: The vibrational and rotational degrees of freedom in a molecule add complexity that complicate optical cycling and state preparation procedures. However, the same additional degrees of freedom also make molecules suitable candidates for tests of physics beyond the standard model. A precision measurement of the transition energy between two vibrational...

Description:: To relate the mechanical responses of hard-soft copolymer systems with their microstructures, a coarse-grained molecular dynamics (CGMD) approach is employed. With the generic bead-spring polymer model mapped from atomistic simulations, this dissertation first studies the morphology of structures with various hard-soft compositions and interactions between hard beads. Following that, this...
