Many recent theoretical and experimental techniques have been developed to probe the structurefunction relationships of complex biomolecules. The roles of RNAs are dependent upon various intricate structural motifs and interactions, including hairpins, pseudoknots, long range territory contacts, bulges and internal loops, that are not easily captured by these methods. We had previously developed an enhanced replica exchange molecular dynamics method that incorporated secondary structure information in the form of distance restraints in order to effectively overcome kinetic barriers and sample conformational space. In several structures, restrained RNA base pairs near large bulges displayed a preference for stacking over hydrogen bonding …

Legacy Theses & Dissertations (2009 - 2024)
TiO2 is a semiconducting material that has been used extensively in many industrial applications, and recently has become a candidate for photocatalytic water splitting, fuel cell anode support materials, sensors, and other novel nanodevices. The interface of TiO2 with water, historically well-studied but still poorly understood, presents a ubiquitous environmental challenge towards the ultimate practical usefulness of these technologies. Ground-state density functional theory (DFT) calculations studying the characteristics of molecular adsorption on model surfaces have been studied for decades, showing constant improvement in the description of the energetics and electronic structure at interfaces. These simulations are invaluable in the …
