A joule heating mechanism for high-speed fused filament fabrication
… Each one of these processes can become a rate-limiting factor for prints. This work explores resistive joule heating as a method to increase heat transfer into an electrically conductive composite feedstock. This requires usage of an electrically insulating liquefier in order to co-locate …

Modelling the atmospheric chemistry of volcanic plumes
… volcanic HCl sustains the cycling. The rate-limiting factor of this cycling, and therefore the rate of O3 destruction, is sunlight. I find qualitative differences between the chemistry of low and high intensity plumes, with the bromine chemistry in the latter case being limited by O3 …

Studies In the Optimization of the Suzuki-Miyaura Reaction
… Pd(0) complexes and it is possible that the rate limiting factor may be catalyst formation. If so, then the development of an optimized method for forming these catalytic species would be a significant contribution to this field. The following work describes research efforts to determine the …

Improving Anaerobic Digestion of Sewage Sludge Using Free Ammonia Pretreatment
… generally limited. Hydrolysis is considered a rate-limiting factor and the low degradation extent of sludge is also the limiting factor. Free ammonia (FA) pretreatment has been recently revealed as a promising approach to improve the biochemical methane potential and hydrolysis rate of sewage …

Fabrication of Macadamia Nutshell Powder-AI/Fe Metal Oxide Modified Diatomaceous Earth Composite Beads for Fluoride and Pathogen Removal Groundwater
… The regeneration studies of MNS demonstrated that the adsorbent can be regenerated for up to 7 cycles using 0.01 M HCl and this clearly indicates the reuse potential of the adsorbent. MNS show no zone of inhibition (bacterial activity) towards the Escherichia Coli and Staphylococcus …

Mechanics of living cells: nonlinear viscoelasticity of single fibroblasts and shape instabilities in axons
… adopt a regular, symmetrical shape and generate forces. When a constant cell length is imposed, an increase with time of the pulling force can be observed. This active behaviour can be probed in more detail by superimposing small-amplitude oscillations at frequencies in the range 0.1--1 Hz. …

The thermodynamics, kinetics and modelling of fast-charging lithium-ion batteries featuring crystallographic shear niobium metal oxide anodes
… with a nominal potential around 1.6 V, charging rates >5C and a cycle-life projected over 10,000 cycles. Chapter 1 shows that the exact potential can be tuned further by changing the average oxidation state through substitution of Nb<sup>5+</sup> with for example W<sup>6+</sup> or …
