Human Steroid Sulfatase: Inhibitor Studies and Photoaffinity Labeling
(University of Waterloo, 2010-09-22)Steroid sulfatase (STS) is considered to be one of the key enzymes contributing to the development of breast cancer. It catalyzes the hydrolysis of inactive sulfated steroids such as estrone sulfate (ES) to inorganic ... -
Hybrid Cathode for All-Solid-State Li-S Batteries
(University of Waterloo, 2021-09-03)Lithium-sulfur (Li-S) battery is one of the most promising energy storage candidates to satisfy the rising demands in multi-functional personal electronics, and the development of electric vehicles due to its high energy ... -
Hybrid Metallic Nanostructures for Bio and Analytical Applications
(University of Waterloo, 2015-01-22)Different hybrid nanoparticles (NPs), including FeM (M=Ni, Au, Pt, Pd) and Fe-biomolecules (biomolecule=glucose oxidase, p53p protein), have been synthesized by a surfactant-free, single-step electrochemical method. FeNi ... -
Hybrid Path Integral Monte Carlo/Molecular Dynamics Approach for the Simulation of Rigid Rotating and Translating Molecules
(University of Waterloo, 2020-01-23)The path integral formulation of quantum statistical mechanics [1] is widely used for formulating the partition function and diverse thermodynamic properties. The basic objective of this thesis is to present the benchmark ... -
Hybrid Transparent Conductive Oxide Nanostructured Materials for Photovoltaic Applications
(University of Waterloo, 2015-10-09)In Ontario, there are great incentives to invest in solar cell research through the Feed-In Tariff program, which has successfully increased the total connected capacity of solar power in Ontario to well over 215 MW. ... -
Hydride Generation as a Sample Introduction Technique for Detection of Arsenic by Microplasma
(University of Waterloo, 2023-12-08)Microplasma can be used as a portable analytical instrument for elemental analysis of samples due to their small size, low power consumption, low carrier gas consumption, and low cost. This is specifically important for ... -
Hydrogel porosity controlling DNA-directed immobilization of gold nanoparticles revealed by DNA melting and scanning helium ion microscopy
(Royal Society of Chemistry, 2012-04-07)Immobilization of nanomaterials is important for many applications, including sensor development, biomaterials design and catalysis. DNA-directed immobilization has been widely used because of its high specificity and ... -
