Growth, Characterization and Assembly of Lead Chalcogenide Nanosemiconductors for Ionizing Radiation Sensors
(2022)
The demand for precise and efficient nuclear radiation detection has increased dramatically, particularly in numerous scientific disciplines, as well as homeland security and medical imaging applications. Modern methods ...
Ultrafast Hydration Dynamics Near Extended Macromolecular Interfaces
(2019)
Liquid water is arguably the most complex, but interesting chemical, enabling development and sustenance of life. The tetrahedral geometry of the water molecule allows the formation of a dense network of hydrogen bonds ...
A Tale of Two RNAs: Single Molecule Investigation of the Conformation, Dynamics and Ligand Binding to the PreQ1 and T-box Riboswitches.
(2014)
Riboswitches are structured mRNA domains that can bind cellular metabolites and control gene expression of downstream genes mainly via transcription attenuation or inhibition of translation initiation. Although structures ...
Fundamental and Applied Electrochemistry for Photonic Applications
(2020)
Photonic devices that selectively transmit or reflect light are highly desirable in a wide variety of applications, including energy harvesting, aesthetic decorations and optical displays. However, most of these high ...
Modeling Morphology Evolution for Nanostructured Electrochemical Systems.
(2015)
In this dissertation, we examine the morphological evolution of two nanostructured electrochemical systems, the growth of anodic alumina and the electrodeposition/electrodissolution of magnesium. These systems are investigated ...
Biophysical Approaches to Target Protein-Protein Interactions of Epigenetic Complexes by Small-Molecule Inhibitors
(2019)
Innumerable biological systems rely on Protein-Protein Interactions (PPIs) to govern basal physiological processes. Deregulation of PPIs is implicated in various human diseases, and PPIs have thus been frequently promoted ...
All-Electron Ground-State and Time-Dependent Density Functional Theory: Fast Algorithms and Better Approximations
(2019)
Density functional theory (DFT), in its ground-state as well as time-dependent variant, have enjoyed incredible success in predicting a range of physical, chemical and materials properties. Although a formally exact theory, ...
Nanopores with Fluid Walls for Characterizing Proteins and Peptides.
(2012)
Nanopore-based, resistive-pulse sensing is a simple single-molecule technique, is label free, and employs basic electronic recording equipment. This technique shows promise for rapid, multi-parameter characterization of ...
Investigations of Excited States and Radical Ions in ?-Conjugated Polymers of Interest for Photovoltaic Applications
(2017)
Photovoltaics using polymer semiconductors as active materials require donor/acceptor (D/A) interfaces to convert excitons into freed charges. In the absence of chain defects, excited states and charges migrate most ...
Development & Application of Constant pH Molecular Dynamics (CPHMD ) for Investigating pH-mediated Transient Conformational States and Their Effects on Nucleic Acid & Protein Activity.
(2015)
pH is a ubiquitous regulator of biological activity, with widespread impact ranging from its role in catalysis to carcinogenesis. Traditionally, a combination of biophysical and computational methods are used to measure ...
