Abstract:

Quantitative utilization of L-cysteate (2-amino-3-sulphopropionate) as the sole source of carbon and energy for growth of the aerobic, marine bacterium Silicibacter pomeroyi DSS-3T was observed. The sulphonate moiety was recovered in the medium largely as sulphite, and the appropriate amount of the ammonium ion was also observed. Genes [suyAB (3-sulpholactate sulpho-lyase)] encoding the known desulphonation reaction in cysteate degradation were absent from the genome, but a homologue of a putative sulphate exporter gene (suyZ) was found, and its neighbour, annotated as a D-cysteine desulphhydr

Metal ion transfer between sulphide minerals was determined.<br>Metal ion production with minerals in pairs was different from that for single minerals.

Abstract:

Lithium-ion batteries (LIBs) are an integral part of consumer electronic devices and electric vehicles. There is a growing need for LIBs with higher capacity, rate performance and cycling stability. At the anode electrode these challenges are being addressed for instance by utilising materials with higher theoretical capacity compared to graphite (372 mAh/g) or by optimising the morphology of materials through nanostructuring of the electrode. In this thesis the former is investigated by synthesising a reduced graphene oxide (rGO) tin sulphide (SnS2) hybrid, and the latter by self-assembly of

Abstract:

Luminescence measurements have been applied to three different structures namely, sulphate, fluorides and YAG. In all cases the RE doping suppresses the intrinsic emission and results in intense luminescence characteristic of the RE dopant. Additionally, in double doped samples, or contaminated ones, the TL data show that each dopant defines a glow peak, which is displaced in temperature relative to the others. Examples of this were discussed for CaS04:Ce,Mn; YAG:Nd,Tb,Cr,Mn; BaF2:Ho,Ce and BaF2:Tm,Ce. The data are discussed in terms of an energy transfer model between different parts of exten

Abstract Waterflooding is an important method for improving oil recovery, it consists of injecting water into selected injector wells to displace the oil to the surrounding producer wells while maintaining reservoir pressure.

A particular issue is mineral scale formation resulting from the mixing of incompatible brines. An example is barite precipitation following the mixing of barium rich formation water with an injection water high in sulphate. Accurately predicting the fr

The rates of precipitation showed parabolic dependence on the relative supersaturation, in agreement with literature reports for lower supersaturations and seeded growth. It was therefore suggested that the test phosphonates affected mainly the high apparent order nucleation process, allowing the crystal growth proces

Abstract:

Abstract Results from laboratory trials of a probe that contains a number of sensors that detect the formation of a biofilm, by its effect on electrical conductivity, and the subsequent build-up of corrosive concentrations of sulphide and/or hydrogen ions at the base of the biofilm will be presented. The sensors are produced using a screen printing process, which should ensure a low cost so that they can, if necessary, be considered expendable and replaceable.

Abstract:

The geology of the Montney Formation and the geochemistry of its produced fluids, including nonhydrocarbon gases such as hydrogen sulfide were investigated for both Alberta and BC play areas. Key parameters for understanding a complex petroleum system like the Montney play include changes in thickness, depth of burial, mass balance calculations, timing and magnitudes of paleotemperature exposure, as well as kerogen concentration and types to determine the distribution of hydrocarbon composition, H2S concentrations and CO2 concentrations. Results show that there is first-, second- and third- or

Abstract:

In the last decade, the Lower Triassic Montney Formation of the Western Canada Sedimentary Basin (WCSB) has undergone significant development, providing a rich dataset to study structural, stratigraphic, and facies control on the variations in hydrogen sulphide (H2S) gas content. Splitting the siltstone dominated Montney into the three regional members (i.e., Lower Montney, Middle Montney, and Upper Montney) allows for detailed analysis on the enrichment of H2S within a local-scale study area in northeastern British Columbia (BC). Within this study area, Upper Montney H2S content increases wit

Abstract:

This project aims to model the kinetic controls on sulphide composition due to the extraction of chalcophile elements from silicate magmas, and use the numerical models to deepen our knowledge of the physical constraints that govern sulphide dynamic processes (e.g., breakup, coalescence, transport and deposition) in magmatic system. Based on the new understanding obtained from these forward models, we then take the textural and compositional features of sulphide globules from the field investigation at Raglan komatiite-associated deposits for instance, to better understand the control on entra

Abstract:

Review question / Objective: The main objective of this research is to find answers to whether an adjusted low dose or an abbreviated regimen or even a single loading dose of magnesium sulphate prophylaxis is capable of preventing eclampsia in severe preeclamptics instead of applying full traditional dosing and if so, which regimen among them can be suggested safely and finally, even if chosen, can any of this modified regimen be applicable for all severely preeclamptic women indiscriminately? With the above context, we have done a systematic review of available studies that compared the effec
