Biosensing at an individually addressable electrochemical array
(University of Waterloo, 2006)In this thesis, a novel electrochemical array is reported. The array consists of two planar halves, each having four carbon screen-printed band electrodes (SPEs), orthogonally facing each other and separated by a spacer ... -
Bismuth Sulfide Nanoflowers for Detection of X-rays in the Mammographic Energy Range
(Nature, 2015-03-24)The increased use of diagnostic x-rays, especially in the field of medical radiology, has necessitated a significant demand for high resolution, real-time radiation detectors. In this regard, the photoresponse of bismuth ... -
Black hole dynamics in Effective Field Theory extensions to General Relativity
(University of Waterloo, 2023-09-22)This thesis aims to develop and implement mathematical and numerical techniques to enable the study of deviations from General Relativity (GR) in the nonlinear regime. The focus is on studying the nonlinear dynamics of ... -
The black hole information paradox in a brane world
(University of Waterloo, 2023-06-28)Recent progress in our understanding of the black hole information paradox has led to a new prescription for calculating entanglement entropy, which involves special subsystems in regions where gravity is dynamical, called ... -
Black Hole Thermodynamics and the Tunnelling Method for Particle Emission
(University of Waterloo, 2008-08-29)The semi-classical black hole tunnelling method is a useful technique to calculate black hole temperature and understand black hole thermodynamics. I will investigate the black hole tunnelling method in detail. I will ... -
Black holes in cosmological spacetimes and alternative theories of gravity
(University of Waterloo, 2023-08-09)This thesis is dedicated to the study of spacetimes surrounding black holes within the context of cosmology, high energy physics and modified theories of gravity. We do this by applying and adapting modern numerical ... -
Black Holes in Pseudo-Topological Gravity
(University of Waterloo, 2009-08-05)In the following, we build on previous work done on higher derivative gravity, in particular Lovelock gravity. The latter is a family of theories in higher space-time dimensions in which interactions involving higher ... -
Block Copolymer-Directed Assembly of Nanoparticles: Forming Mesoscopically Ordered Hybrid Materials
(American Chemical Society, 2002)Mixtures of diblock copolymers and nanoscopic spherical particles can yield well-ordered hybrid materials, which can be used for separation processes, catalysis, and optoelectronic applications. Predicting the morphologies ... -
The blood compatibility challenge. Part 3: Material associated activation of blood cascades and cells
(Elsevier, 2019-08)Following protein adsorption/activation which is the first step after the contact of material surfaces and whole blood (part 2), fibrinogen is converted to fibrin and platelets become activated and assembled in the form ... -
Blue emitting gold nanoclusters templated by poly-cytosine DNA at low pH and poly-adenine DNA at neutral pH
(Royal Society of Chemistry, 2012-07-11)Blue fluorescent gold nanoclusters were prepared in the presence of poly-cytosine DNAs at low pH and poly-adenine at neutral pH using citrate as the reducing agent; various buffer conditions affecting the synthesis have ... -
Bohmian Mechanics: Towards Illuminating The Quantum Potential
(University of Waterloo, 2018-02-20)This thesis deals with the theoretical and experimental details of trying to understand and infer the quantum potential from Bohmian mechanics using Bohmian trajectories. In this work, some of the key components of the ... -
Bone health in adults with epilepsy
(University of Waterloo, 2017-08-30)Epilepsy has been associated with an increased fracture risk by various studies in the literature. This is attributed to the decreased bone mineral density (BMD) linked to the anti–epileptic drugs (AEDs) that are used to ... -
Boosting the oxidase mimicking activity of nanoceria by fluoride capping: rivaling protein enzymes and ultrasensitive F- detection
(Royal Society of Chemistry, 2016-07-28)Nanomaterial-based enzyme mimics (nanozymes) are currently a new forefront of chemical research. However, the application of nanozymes is limited by their low catalytic activity and low turnover numbers. Cerium dioxide ... -
Bootstrapping Quantum Field Theories
(University of Waterloo, 2024-01-23)This thesis compiles a few developments on the S-matrix bootstrap, conformal field theory, and integrability in N = 4 SYM. After an introduction contextualizing the various works that compose this thesis, we present a ... -
Born Geometry
(University of Waterloo, 2020-04-21)In this thesis, we summarize the work which we authored or co-authored during our PhD studies and also present additional details and ideas that are not found elsewhere. The main topic is the study of T-duality in theoretical ... -
Born Reciprocal Representations of the Quantum Algebra
