Two-Dimensional Chalcogenides : Material Synthesis And Nano-Device Applications, Robin Bay Jacobs-Gedrim

Legacy Theses & Dissertations (2009 - 2024)

Low-dimensional nanostructures exhibit distinct properties from their bulk counterparts. Here the synthesis of novel low-dimensional nanostructures is demonstrated using both top down and bottom up processes and their properties are investigated. Two-dimensional (2D) binary sesquichalcogenides are introduced as a viable material platform for phase change random access memory, photodetection, and the investigation of topological insulator surface states. An exponential relationship is observed between layer thickness and energy consumption during switching of 2D phase change devices, ultra-high responsivity in 2D photoresistors, and surface-rich conduction in 2D topological insulator nanoplates. Additionally, methods for the assessment of chemical purity, stoichiometry, and dimensions of …

Computational Investigations Of Potential Energy Function Development For Metal-Organic Framework Simulations, Metal Carbenes, And Chemical Warfare Agents, Christian R. Cioce

USF Tampa Graduate Theses and Dissertations

Metal-Organic Frameworks (MOFs) are three-dimensional porous nanomaterials with a variety of applications, including catalysis, gas storage and separation, and sustainable energy. Their potential as air filtration systems is of interest for designer carbon capture materials. The chemical constituents (i.e. organic ligands) can be functionalized to create rationally designed CO2 sequestration platforms, for example. Hardware and software alike at the bleeding edge of supercomputing are utilized for designing first principles-based molecular models for the simulation of gas sorption in these frameworks. The classical potentials developed herein are named PHAST -- Potentials with High Accuracy, Speed, and Transferability, and thus are designed …

Wavelength Dependent Specific Plasmon Resonance Coupling Of Single Silver Nanoparticles With Egfp, Kerry J. Lee, Tao Huang, Prakash D. Nallathamby

Chemistry & Biochemistry Faculty Publications

Noble metal nanoparticles (NPs) possess unique plasmonic properties, enabling them to serve as sub-diffraction light sources and nano-antennae for a wide range of applications. Here we report the specific interaction of single Ag NPs with single EGFP molecules and a high dependence of their interaction upon localized-surface-plasmon-resonance (LSPR) spectra of single Ag NPs and EGFP. The LSPR spectra of single red Ag NPs show a stunning 60 nm blue-shift during their incubation with EGFP, whereas they remain unchanged during their incubation with bovine serum albumin (BSA). Interestingly, the peak wavelengths of the LSPR spectra of green and blue Ag NPs …
