Abstract: <p>Innovative strategies to manage copious waste streams by upcycling feedstocks to valorized products which are then used in environmental remediation applications is an attractive circular economy model. This thesis explores this approach using waste wood generated from the milling of Chlorocardium rodiei (greenheart), a tropical hardwood species abundant in Guyana. We evaluate the… more Year: 2025, 2025

However, their structural versatility is limited by the scarcity of commercial precursors and challenging modification procedures. Furthermore, we have investigated its coordination… more Year: 2023, 2023

Abstract: <p>The generation of polymer brushes by surface-initiated polymerization techniques has become a powerful tool for the creation of hybrid materials. Governed by the type and amount of polymer used in the modification, the chemical and physical properties of a surface can be tailored by polymer grafting. In this study, a commonly used polymer flocculant, polyacrylamide (PAM), was grafted… more Full Text: Grafting Polyacrylamide from the Surface of Activated Carbon for Flocculation Applications A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and …

This is a two-component sol-gel system with 3-methacryloxypropyltrimethoxysilane (MaPTMS) and tetraethoxysilane (TEOS). Herein we show that if we change the co-solvent required for solubilizing MaPTMS from the more common methanol and… more Full Text: UV-Curable hybrid sol-gel materials: The development and application of a 3methacryloxypropytrimethoxysilanederived coating A Thesis submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Doctorate of …

Abstract: <p>Giardia intestinalis is a protozoan parasite that causes waterborne diarrheal disease in animals and humans. It is an unusual eukaryote as it lacks the capacity for heme biosynthesis; nonetheless it encodes heme proteins, including three cytochrome b5 isotypes (gCYTB5s) of similar size. Homology modelling of their structures predicts increased heme pocket polarity compared to mammalian… more Full Text: ELECTROCHEMICAL CHARACTERIZATION OF GIARDIA INTESTINALIS CYTOCHROMES b5 A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Masters of Science in the Faculty of Arts and Science TRENT …
