Bismuth Binding In Human Metallothionein, Emily M. Toswell
Bismuth Binding In Human Metallothionein, Emily M. Toswell
Undergraduate Student Research Internships Conference
Bismuth metal is one of the least toxic heavy metals for humans. It is used in a wide variety of applications including organic synthesis, cosmetics and pharmaceutical applications. In biomedicine, bismuth is a therapeutic metal used in metallodrugs such as Pepto Bismol for its antimicrobial and antibacterial properties. Metallothionein (MT) is a cysteine rich protein found in the liver, kidneys, brain and central nervous system. MT can bind a variety of metals including essential metals such as zinc and copper. This research investigates the binding pathway of Bi[EDTA]- with fully metallated Zn7MT by using mass-spectrometry and UV-vis absorption.
Design And Surface Modification Of Noble Metal-Based Nanocatalysts, Xuchun Wang
Design And Surface Modification Of Noble Metal-Based Nanocatalysts, Xuchun Wang
Electronic Thesis and Dissertation Repository
This thesis investigates approaches to modifying the surface structure of noble metal-based nanocatalysts. Noble metal-based nanocatalysts, such as Pt and Pd, play a significant role in heterogeneous catalysis due to their capabilities in activating the cleavage or formation of chemical bonds, but still suffer from the high-cost issue and unsatisfied catalytic performance due to too strong or too weak adsorption of intermediates. Considering the surface specificity of heterogeneous catalysis, Bi, a cheap metal, was used to modify the surface of Pt- and Pd-based nanocatalysts. This thesis aims to unveil the role of Bi in improving their catalytic performance from both …
