Hydrogen atoms interactions with single crystal surfaces are the simplest processes in surface science, which are of both practical and fundamental interest. Chemical reactions of hydrogen atoms with single crystal surfaces lead to adsorption. Despite the fact that it has been studied for decades, the dynamics of hydr…
ABSTRACT\nThe transition of sports bras’ uses, from an active lifestyle to resting activities, requires dynamic and adaptable comfort properties of the design, as well as adequate breast support, fit, and comfort. Thus, the two-fold purpose of this study was to: (a) analyze the use of current materials and processes i…
This thesis explores the synthesis of MXene-epoxy nanocomposites. MXenes are a family of two-dimensional materials which display versatile chemistries that allow the material to be tuned for applications that include electrochemical storage devices, electromagnetic interference shielding devices, and catalysts, to nam…
This is a set of silver nanoparticle FINAL CONFIGURATIONS, for use in data driven studies. These structures have been optimized (fully relaxed) using Density Functional Tight Binding. Sizes range from 13 atoms to 2947 atoms, with a variety of shapes as described in the accompanying metadata file. All files are in XYZ…

Nanocrystalline (nc) materials, a single or multi-phase polycrystalline solids with a grain size of a few nanometers, typically less than 100 nm have attracted considerable attention of research community. However, investigation of corrosion/oxidation resistance of these materials has attracted limited research attent…
The Mug Share program at the University of British Columbia (UBC) is currently in the early stages of a pilot project, and this paper aims to help guide the growth of the initiative through researching scientific literature to assess the life cycle analysis of several mug options, providing examples of similar project…
The conversion efficiency of conventional silicon (Si) photovoltaic cells has not been improved significantly during last two decades but their cost decreased dramatically during this time. However, the higher price-per-watt of solar cells is still the main bottleneck in their widespread use for power generation. Ther…
A dissertation submitted to the Faculty of Science and Agriculture in fulfillment of the requirements for the Degree of Master Of Science (MSc) in the Department of Biochemistry and Microbiology at the University Of Zululand, 2018
Thermoplaste bieten als Matrixmaterial in carbonfaserverstärkten Kunststoffen einige Vorteile gegenüber den duroplastischen Matrixsystemen. Insbesondere im Bereich der Verarbeitung ermöglicht die Schmelzbarkeit der thermoplastischen Matrix Herstellungs- und Verarbeitungsprozesse, die mit Duroplasten nicht möglich sind…
A Luneburg lens is a beam former that has two focal points where one isat the surface and the other lies at innity. It is a cheap passive steerableantenna at high frequencies. In this thesis, a 2D at-prole Luneburglens with all-metal structure is designed for Ka band. Commercial softwareCST Microwave Studio Suite and…
This report summarizes the outcome of an expert panel review of a key degradation phenomenon identified for atmospherically exposed austenitic stainless steel containers used for the interim dry storage of used nuclear fuel - specifically, chloride induced stress corrosion cracking due to the presence of atmospherical…
Ce travail de doctorat est consacré à la production, au recyclage mécanique long-terme et à la caractérisation de matériaux polymères et composites à base de polyéthylène haute densité (HDPE) et de fibre de lin. L’objectif est de déterminer l’aptitude au recyclage long-terme de ces composites et de leur matrice, tout…
Halloysite nanotubes (HNTs) offer excellent improvements in wide range of physical and engineering properties at low filler content. Due to their outstanding properties such as large aspect ratio, high surface area, flame retardant and good optical clarity, HNTs polymer nanocomposites are widely used in automotive, co…
Fouling affects a wide range of industries around the globe. The two main categories of fouling are the unwanted adhesion of solids, and the unwanted adsorption of liquids. The purpose of this thesis is to understand and design new mechanisms to mitigate fouling. As fouling always occurs at the interface between a sur…
Butt fusion welding process is an extensively used method of joining for high density polyethylene (HDPE) pipe.With the increasing number of HDPE resin and pipe manufacturers and the diversity of industries utilising HDPE pipes, a wide range of different standards have evolved to specify the butt fusion welding parame…
a web database is provided which can be used to calculate photon cross sections for scattering photoelectric absorption and pair production as well as total attenuation coefficients for any element compound or mixture z 100 at energies from 1 kev to 100 gev xcom provides two forms of output a tables which correspond c…
Silicon carbide (SiC) is an attractive material for high-voltage and high-temperature electronic applications owing to the wide bandgap, high critical electric field, and high thermal conductivity. High- and ultra-high-voltage silicon carbide bipolar devices, such as bipolar junction transistors (BJTs) and PiN diodes,…
Syntactic foams are light weight particulate composites that use hollow particles (microballoons) as reinforcement in a polymer resin matrix. High strength microballoons provide closed cell porosity, which helps in reducing the weight of the material. Due to their wide range of possible applications, such as in marine…
Progress within the field of biofabrication, and specifically additive manufacturing, is dependent on the development of hydrogel formulations and printing strategies. Biofabrication is an important tool for the creation of engineered tissue constructs, resembling native tissue in the positioning of biologically relev…
