This thesis describes the development of high-capacity, next generation Li-ion battery electrodes based on germanium and silicon nanostructures grown directly from stainless steel current collectors. The core chapters ...

This thesis describes the formation of Si and Ge nanostructures using two growth systems. Chapter 3 details the controlled growth of Ge nanowires and nanorods using a surfactant-free hotplate based growth method. Control ...

The integrative conjugative elements, ICE s SXT and R391 are the prototypes of a group of gram negative integrative elements known as the SXT/R391 group. R391 was identified in a clinical isolate of Providencia in the ...

Time-resolved step-scan FTIR spectroscopy has been employed to probe the dynamics of the ba3 oxidoreductase from Thermus thermophilus in the ns-µs time range and in the pH/pD 6-9 range. The data revealed a pH/pD sensitivity ...

This study aims to provide a geometrical description of biomass particles that can be used in combustion models. The particle size of wood and herbaceous biomass was compared using light microscope, 2D dynamic imaging, ...

Metal-organic materials (MOMs) that contain molecular building blocks (MBBs) or supermolecular building blocks (SBBs) have attracted considerable attention in the field of materials science due to their modular nature ...

Nanoporous gold (NPG) obtained via dealloying of Au alloys has potential applications in a range of fields, and in particular in bioelectrochemistry. NPG possesses a three dimensional bicontinuous network of interconnected ...

Microbial contamination management is a crucial task in the food industry. Undesirable microbial spoilage in a modern food processing plant poses a risk to consumers’ health, causing severe economic losses to the manufacturers ...

This thesis investigated a number of solution mediated and solid state polymorphic transformations between the 5 known polymorphs Sulphathiazole. The polymorphs were isolated in their pure states and characterized. This ...

This study aims to investigate the interaction between potassium and carbonaceous matrix of soot produced from wood and herbaceous biomass pyrolysis at high heating rates at 1250 C in a drop tube reactor. The in uence of ...
