Using the benzene-based bis-triazole ligand 1,4-di-(1,2,4-triazole-4-yl)benzene(L) and corresponding zinc(II) salt, under hydrothermal conditions, a novel luminescent 1D Zn(II) coordination polymer, {[Zn(μ2-L)(H2O)4]SiF6·2H2O}n (1) has been isolated and characterized by single-crystal X-ray diffraction, FT-IR, and lum…
In this contribution, a micro-mechanically motivated constitutive model for phase transformation, martensite reorientation and twin formation in shape memory alloys is proposed. The formulation builds on an effective parametrization of the austenite-twinned martensite microstructure through first- and second-order lam…
Shape Memory Alloys (SMA) have shown their potential as linear actuators. The study conducted here investigates the use of SMA wires as linear actuators for the control of a rotational actuator. The SMA wires are attached to the sides of the actuator to generate opposing forces which are used to control the position o…
Shape memory alloys are capable of delivering advantageous solutions to a wide range of engineering-based problems. Implementation of these solutions, however, is often complicated by the hysteretic, non-linear, thermo-mechanical behavior of the material. Although existing shape memory alloy constitutive models are la…
Epoxide resins are widely employed as adhesives and are being increasingly used in engineering industries. However, adhesively bonded components may suffer significant loss in strength when exposed to environmental attack. The most severe threat is water, and adhesive joint strength decay can be accelerated if externa…
This study investigates the evolution of filler particle networks using electrical and rheological property measurements. Polyvinylediene Flouride (PVDF) was used as the matrix thermoplastic polymer which was reinforced with multiwall carbon nanotubes (MWNT) as the filler phase using high shear twin screw extrusion mi…

Graphene-based materials have generated tremendous interest in the past decade. Manipulating their characteristics using wet-chemistry methods holds distinctive value, as it provides a means towards scaling up, while not being limited by yield. The majority of this thesis focuses on the surface functionalization of gr…

The structural and electronic properties of linear and branched perfluorobutanesulfonate (PFBS) in its anionic, acidic, and potassium or sodium salt forms were studied in a polarizable continuum model (PCM) of methanol solvent with the B3LYP functional and the 6-31G(d,p) basis set. The 19F chemical shifts and 19F−19F…
Plasmonic properties and the related novel applications are studied on various types of metallic nano-structures in one, two, or three dimensions. For 1D nanostructure, the motion of free electrons in a metal-film with nanoscale thickness is confined in its normal dimension and free in the other two. Describing the fr…
