Complementary computational chemistry and surface science experiments of reaction pathways in aluminum chemical vapor deposition
… require the introduction of new materials and processes concurrent with shrinking device dimensions. These simultaneous demands drastically reduce margins for error and necessitate an increasingly quantitative understanding of semiconductor processes. Leaders of the semiconductor industry have …

Phase equilibria and thermodynamic modelling of the Pb-S-O system and applications to direct lead smelting
… into slag, using a unique controlled-oxidation process. This finding led to the proposition of a novel degangue-matte oxidation process for the production of metallic lead from a clean Missouri concentrate. The process is based on new process chemistry and has the potential of producing very low …

Continuous production of two archetypal metal-organic frameworks using conventional and microwave heating
… in order to gain a deeper understanding of the process chemistry, how process intensification affects the final product and create a continuous MOF-5 synthetic procedure. We have demonstrated that MOF-5 can be formed continuously with high Langmuir Surface Areas (>2000 m² g⁻¹) while also …

A framework for integrating chemistry and process synthesis in the analysis of pathways for chemical manufacture
… for their products and of the manufacturing processes used to make those products. Both development activities are difficult and time-intensive; closer integration of the two may lead to synergies in research, development, and operations. Four issues in integrating process chemistry and …

Chemical kinetic investigation of a commercial batch reactor process
… the efficiency and economics of the batch processes. The batch process models are largely empirical in nature as the reaction mechanism is unknown. The process chemistry and the commercial manufacturing method are described. A small scale system was established in glass and the ability to …

Palladium-catalyzed C-N and C-O cross-coupling reactions
… the 1) synthesis of heterocycles, 2) medicinal chemistry, 3) process chemistry, 4) synthesis of natural products, 5) organic materials and chemical biology, and 6) synthesis of ligands. The large number of applications highlights the versatility and utility of this transformation both in …

Investigation into the kinetics, mechanisms and particle characteristics of selenium precipitation from copper sulphate solution.
… selenium removal is effected by a precipitation process that takes place under high supersaturation conditions which favour nucleation over any other particle formation processes. There is currently no fundamental information on the nucleation kinetics of this important process. Furthermore, the …

Hydrodynamics and Mass Transfer in Bubble Columns
… to have a method that can be used as an online process control tool to identify flow regime, this method has been tested at cold flow conditions and needs to be implemented at hot flow conditions. The parameters (radial distributions of gas hold-up, bubble velocities, and volumetric mass …

Scale-up and optimisation of the β-chloroacrylamide process by batch and continuous flow methods
… to optimise and scale-up a complex API-like process through advanced process control to yield the final product with optimum quality and phase purity. The first chapter of this thesis presents an overview of the mechanistic pathway leading to the formation of these compounds along with the …

Understanding the molecular-level chemistry of H2O plasmas and the effects of surface modification and deposition on a selection of oxide substrates
… detection and abatement. The abatement process of contaminants in liquid discharges is relatively unstable; thus, to help elucidate the sources of instability, the gas phase constituents of plasmas formed from artificially-contaminated water samples were examined using optical emission …
