Modern devices require fundamental length scales to be analysed in a maximum detail to enable research of new types of phenomena and design new materials. In this thesis, an advancement in Lorentz microscopy will be presented where the focus was placed not only onto resolution in spatial space but also onto resolution…

A temperature-stable, ultra-high permittivity dielectric ceramic, based on CTLNT, has been successfully fabricated at significantly reduced sintering temperatures with no deterioration of microwave properties, through the addition of a Bi_4B_2O_9 (BBO) sintering aid. This work has been an extension of previous finding…

Heat, light and electricity are three foundation pillars not only of physics, but also of our daily lives. Therefore, these have been studied by scientists for centuries and an always better understanding of the underlying exchange particles, phonons, photons and electrons, was gained. In physics, core disciplines ope…
Field grading material based microvaristors are widely used to minimise the localised field enhancement which could trigger corona and partial discharges in high voltage equipment. In this research, two different microvaristor powders, A and B are composed of silicone rubber matrix at certain filler concentration. The…
Cellulose is a versatile, abundant and biocompatible polymer. New biobased polymers with tailor-made properties can be obtained by chemical modification with small organic molecules. Furthermore, well defined cellulose based graft copolymers can be generated with controlled radical polymerisation techniques of organo…
Yield strength and elongation are both important properties of engineering alloys, but they typically exhibit an inverse correlation and engineers are forced to design around this constraint in applications of the alloys. It was recently reported that precipitation hardenable Al alloys subjected to a new type of heat…
Paper materials have a long history of use as a packaging material, although traditional paper-based packaging is limited in its shape, complexity, and design. In order to better understand the deformation and failure mechanisms during 3-D forming, two experimental studies of paper materials have been conducted. Furth…
The evolution of a two-phase Hele-Shaw problem, a Muskat problem, under assumption of a negligible surface tension is considered. We use the Schwarz function approach and allow the sinks and sources to be line distributions with disjoint supports located in the exterior and the interior domains, a two-phase mother bod…
Abstract Mild steel continues to be the most extensively used construction material in several industries. However, steels suffer from corrosion in aqueous solutions. Coating is one of the common measures to circumvent corrosion. Silane coating is among the recent and promising measures to improve the corrosion resist…

Formaldehyde is known as the building block in many industries including resins, polymers, paints and adhesives. It is widely used in furniture and wood processing. The annual production rate of formaldehyde is in the range of 30 million tons globally and the demand of formaldehyde has grown by 2-3 % per year over the…
A semiconductor is a type of material which has electrical properties in between an \ninsulator and a conductor. A conductor can be thought of as a group of atoms surrounded \nby a sea of free electrons, which are free to move throughout the material; in contrast, \nthe electrons in an insulator are tightly localized…
An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space grou…
The purpose of this paper is to survey the progress on the Jordan decomposition problem in integral group rings of finite groups, updating an earlier 1999 survey \cite{HP:1999}, and to highlight the various contributions of Don Passman to this work. Various open questions in this area are presented and several differe…
