Simulation And Software Development To Understand Interactions Of Guest Molecules Inporous Materials, Douglas M. Franz Jul 2019

Simulation And Software Development To Understand Interactions Of Guest Molecules Inporous Materials, Douglas M. Franz

USF Tampa Graduate Theses and Dissertations

The effect of inclusion of explicit polarization is investigated through several theoret- ical studies of crystalline porous materials herein. In addition to the use of Monte Carlo simulation for such studies, a robust molecular dynamics software is presented which is suitable for analyzing time dependent properties of gases or other molecules in porous materials and other condensed phase systems. Metal-organic frameworks (MOFs) are the main focus of the work included here, a relatively young class of materials originally in- troduced in the early 1990s. These are usually three dimensional crystalline nanoporous materials that exhibit unique properties such as gas separation, …


Functional Porous Materials: Applications For Environmental Sustainability, Briana Amaris Aguila May 2019

Functional Porous Materials: Applications For Environmental Sustainability, Briana Amaris Aguila

USF Tampa Graduate Theses and Dissertations

Resource depletion, clean water shortages, and global climate change have led to environmental sustainability being of primary concern for both governmental and industrial practices. Current methods to address these challenges typically come as a double-edged sword, fixing one problem while contributing to another. As introduced in chapter one of this dissertation, adsorbent materials are seen as a promising alternative remediation system due to their low energy consumption and minimal chemical waste production. However, many traditional adsorbents, such as activated carbon, metal oxides, and resins, are hindered in practice. This is because they lack the structural tunability to have long-term effectiveness …
