This study focuses mainly on the normal stresses that are caused by applied forces. As a case study, the present work aims at investigating the bi-dimensional contact mechanics of wavy cosinusoidal anisotropic finite planes. To achieve this objective, results on the displacement and stress component are first calculated with the help of the Lekhnitskii formalism.

In the present work, palladium nanoparticles were synthesized in glycerol following the bottom-up methodology, using Pd(II) and Pd(0) precursors. The as-prepared materials were characterized by transmission electron microscopy (TEM) and powder X-ray diffraction (XRD), evidencing the formation of zerovalent palladium spheres in the nanosize ranges.

In this work, Ag(Cu)InS2 semiconductor nanoparticles were synthesized via microwave and solvothermal methods. The effects of synthetical parameters on the structure and morphology of the nanoparticles were characterized by XRD, SEM, TEM, UV–Vis, and EDX. The experimental results reveal that the AgInS2 compound can be crystallized in two different phases, which are tetragonal and orthorhombic.

This work aims at investigating the effect of aleatoric uncertainty of creep rock properties on the stability of an underground structure. This uncertainty relates to the spatial variability of the mechanical parameters representing the time-dependent behavior of geological rock formation due to the change in its mineralogy.

Red phosphorus is an important ingredient in the manufacture of pyrotechnic smoke and is likely to be in service for many years. One of the most effective ways to use smoke screens is to protect special vehicles from laser and infrared guidance systems. In this work, the formulation, obscurant and emission characteristics of the smoke composition in smoke devices used in special vehicles were determined and evaluated.

In this work, nano-SiO2 have been used as nanocarriers for loading Ce(III) ions (SiO2@Ce3+). After loading, silane coupling agent has been used to modify these nanocarriers (m-SiO2@Ce3+). Then, these modified nanocarriers were added as green inhibitors into the inner epoxy coating matrix, which was based on the epoxy resin (DER 671X75) and hardener (polyamide Epicure 3125). Morphological study by FE-SEM showed that the spherical nanoparticles (mSiO2@Ce3+) were in size < 100 nm and dispersed rather homogeneously into the polyme matrix.

In this work, gold nanorods (AuNRs) with well-controlled aspect ratios were prepared using a modified seedgrowth method and covered by TiO2 layers through the hydrothermal reaction to improve stability. Integrating TiO2 with plasmonic rod-like gold nanoparticles could enhance their photo activity by the local surface plasmon resonance (LSPR) effect. AuNRs aspect ratios were controlled by varying the amount of seed solution, reducing agents, surfactant (CTAB), and titanium (IV) but oxide.

This work demonstrated the potential of US for mitigating membrane fouling. However, the integration of the US transducers within the membrane system will be a major challenge for the application of US in membrane cleaning. It is more appropriate that US is used as pre-treatment to the membrane system, the transducers can be placed prior to the coagulant feed line. Further work on the determination of the detailed mechanisms associated with enhancing coagulation would enable optimisation of the system with regard to process, cost and energy efficiency.

Once entirely the domain of space-borne applications, the effects of high energy charged particles on electronics systems is now also a concern for terrestrial devices. Reconfigurable components such as FPGAs are particularly vulnerable to radiation single event effects (SEU) as they carry a large amount of memory within a relatively small amount of circuit area. This thesis presents a Silicon on Insulator (SOI) based configuration memory system in a radiation hard reconfiguration system.
