Investigation of Crystal Structures and Ultra-Low Thermal Conductivities in Novel Group 14 and 15 Chalcogenides
(University of Waterloo, 2023-12-04)The crystal structures and physical properties of several new group 14 and 15 chalcogenides are discussed in this thesis. The thesis discusses the chalcoantimonates TlLa2Sb3Se9 and La12+zSb9-ySe38-z (simplified as La12Sb9Se38). ... -
Investigation of Current Sensing Using Inherent Resistance
(University of Waterloo, 2010-05-20)A novel method of current sensing using resistance of power delivery path is introduced as a mean to measure static or dynamic load current in high-power system-on-chips, where conventional methods deemed inadequate. It ... -
Investigation of Different Factors Affecting Asphalt Cement Ageing and Durability
(University of Waterloo, 2019-08-21)Asphalt cement is an organic material and, like any other organic material tends to react with atmospheric oxygen, thus changing its physical properties (more accurately rheological properties) gradually over time. Although ... -
Investigation of Differential Diffusion Effects in Turbulent Hydrogen Jet Flame using Conditional Moment Closure Method
(University of Waterloo, 2014-08-26)The effects of differential diffusion in the numerical modelling of a turbulent non-premixed hydrogen-air jet flame using a Conditional Moment Closure (CMC) method are investigated. The CMC calculations, which are coupled ... -
Investigation of Direct Injection Fuel Sprays in High Velocity Air Flows
(University of Waterloo, 2013-10-24)The study of single-plume sprays into cross-flowing air is found extensively in literature, however, with the continued development of the Spark Ignition Direct Injection (SIDI) engine, the behaviour of multi-plume sprays ... -
Investigation of divalent metal ion detection using 17E DNAzyme Biosensor
(University of Waterloo, 2021-04-30)DNAzymes are in vitro selected oligonucleotides that can catalyze reactions, such as RNA cleavage. Most DNAzymes require metal ions as cofactors. Unlike ribozymes, which have been found in nature, all known DNAzymes are ... -
Investigation of effect of temperature and forming speed on the formability of AA3003 Brazing Sheets
(University of Waterloo, 2016-07-08)The present work investigates the effect of forming temperature and forming speed on the formability of AA3003 aluminum alloy brazing sheet in three temper conditions (O, H22 and H24) and two different thicknesses (0.2 and ... -
Investigation of Effects of Wind Turbine Noise on General Health and Sleep Disturbance
(University of Waterloo, 2016-12-23)ABSTRACT Background: Although wind energy is now one of the fastest growing sources of power in Canada and many other countries, the growth in both number and size of wind turbines (WTs) has raised questions regarding ... -
Investigation of Efficient Synthetic Routes to Conjugated Thiophene-S,S-Dioxide-Based Materials
(University of Waterloo, 2020-10-08)Due to their low cost and desirable properties, many recent efforts in the field of semiconductor research have been devoted to the discovery and investigation of organic materials. Within this field, thiophene-based ... -
Investigation of Electroluminescence Degradation in Anthracene-based Organic Light-Emitting Devices
(University of Waterloo, 2010-09-29)Organic light-emitting devices (OLEDs) have attracted significant attention because of their unique advantages for flat panel display applications. However, the relatively limited electroluminescence (EL) stability of blue ... -
Investigation of Environmental Impacts on Piezoelectric Weigh-In-Motion Sensing System
(University of Waterloo, 2011-09-30)Transportation by trucks plays a major role in North America’s economy. The growth of this industry will increase the loads on existing roads and highways and raises the possibility of overloaded vehicles, which causes ... -
Investigation of enzymes catalyzing the production of acetaldehyde from pyruvate in hyperthermophiles
(University of Waterloo, 2012-09-26)Extreme thermophiles and hyperthermophiles are microorganisms capable of growing optimally at 65-79°C and 80°C plus, respectively. Many of the enzymes isolated from them are thermostable, which makes them a potential ... -
Investigation of excipients for the stabilization of HSV-2 vaccine candidate ACAM529
(University of Waterloo, 2018-05-01)Herpes simplex virus type 2 (HSV-2) is a highly infectious pathogen that causes genital ulcerative disease and it affects millions of people worldwide. ACAM529 is a promising new live replication-deficient vaccine candidate ... -
Investigation of Flavoproteins Involved in the Metabolism of Anaerobic Hyperthermophilic Microorganisms
(University of Waterloo, 2007-09-12)It was estimated that more than one hundred open reading frames in Pyrococcus furiosus and Thermotoga maritima could encode flavoproteins based on the results of motif search and comparison of genomic annotation to the ... -
