Compounding precipitated silica in elastomers
This valuable guide to compounding elastomers with precipitated silica covers principles, properties, mixing, testing and formulations from a practical perspective. This handbook and reference manual will serve those who work on part design, elastomer formulation, manufacturing …
Despite the advantages that composites have over monolithic materials, their use has been restricted by some deficiencies in their properties. The goal of this study was to overcome deficiencies of unidirectional glass fibre epoxy resin composites by coating the fibres with a "t…
Silica nanoparticles are effective fluorophore carriers with high potential in imaging, diagnostics, and therapy. The particles are resistant to drastic change of environmental conditions (pH, temperature etc.) and insulate the dyes so as to protect them from photobleaching. Sil…
A range of mesoporous materials based on SBA-15, KIT-6 and FDU-12 have been prepared using neutral block copolymers Pluronic P123 and F127 and characterised using methods including electron microscopy and nitrogen adsorption. Typically the materials have a hexagonal (p6mm) or cu…
A range of mesoporous materials based on SBA-15 have been prepared and characterised. The materials were templated by neutral block copolymer P123, and typically have a hexagonal (p6mm) pore structure, with high surface areas and narrow pore size distributions. The removal of th…
Azobenzene based photochromics have been studied widely since the development of the first azo dye, Mauvine, by Perkin in 1856. Azo based dyes have been widely used in industry for over a century. The desire to study them arose from their ease of synthesis and the wide availabil…
In this work we have explored the possibility of using surfactant/polyelectrolyte complexes as templates to synthesize inorganic mesostructured materials mainly with a film morphology. Inorganic species deposit in those regions of the films which are filled with a polymer hydrog…

The Bermuda Atlantic Time Series (BATS) is an ongoing 25-year biogeochemical record in the North Atlantic subtropical gyre. Contemporaneous data on the particulate phases of four major bioreactive elements: C, N, P, Si only exist during two years and also for a companion project…
The continual downscaling of the thickness of the SiO 2 layer in the complementary metal oxide semiconductor (CMOS) transistors has been one of the main driving forces behind the growth of the semiconductor industry for past 20-30 years. The gate dielectric works as a capacitor …
The ability to synthesize nanostructured inorganic materials with controlled microstructural and morphological features will provide materials with unique characteristics in unprecedented ways. This thesis investigates the synthesis of porous silica and alumina materials with co…
High-silica zeolites of MFI type were synthesized by rapid crystallization method. The major factors affecting the hydrothermal synthesis were screened using Plackett-Burman experimental design. The pH of the crystallizing mixture was found to be the most important factor. A pH …
In nanomaterials there is a strong correlation between structure and properties. Thus, the design and synthesis of nanomaterials with well-defined structures and morphology is essential in order to produce materials with not only unique but also tailorable properties. The unique…
