Resumen
The detection and monitoring of toxic and explosive gases is often performed using semiconductor gas sensors. The substrate forms an important part of these sensors and current designs were investigated and tested. Various new designs were developed and thick and thin-film technologies employed to fabricate substrates and complete sensors. Substrateless sensors were also analysed and alterations performed to fashion new devices. A number of ceramic materials were tested for their suitability as semiconductor gas sensor substrates. The adhesion of thin-films and thermal conductivity were found

Resumen
Viruses have exploited strategies of proteolysis for the purposes of processing viral proteins and manipulating cellular processes to direct synthesis of new virions and subvert host antiviral responses. Many viruses encode proteases within their genome, of which many have been well studied among the family of positive-sense single-stranded RNA picornaviruses. A subset of host proteins have already been identified as targets of picornaviral proteinases; however, the full repertoire of targets is not known.

Serine proteases are a family of enzymes with a wide array of functions across both eukaryotes and prokaryotes. Here we have attempted to produce the serine proteases rat mast cell protease 2 and mouse mast cell protease 5 in a culture of HEK 293 cells; and mouse mast cell protease 4, platypus granzyme B-like protease and platypus hypothetical protease in a baculovirus expression system. Following production we wanted to analyse these serine proteases using a phage display assay and a battery of chromogenic substrates.

SERS is a useful spectroscopic technique that was discovered 30 years ago, and has recently seen a renaissance in research. Sphere segment void (SSV) substrates have been developed as reproducible, stable SERS substrates by electrodeposition of a metal through a colloidal template. The effect of adsorbing an organic monolayer on the surface of an SSV substrate was studied, which results in a slight shift in the plasmonic absorption. This was compared with the reduction of a diazonium salt on the surface, which results in a significant increase in plasmonic absorption, attributed to a physical

The surface of the samples was polished with different techniques: one is chemical mechanical polish (CMP) and another is mechanical polish (MP). PL data from MP and CMP surfaces show that PL intensity from the CMP-treated surface is much higher than that from the MP-treated surface. This can be explained by defects formed dur

The electrochemical hydroxylation of aromatic substrates was investigated in some detail, with the view to develop a method, which could produce dihydroxybenzenes in acceptable yields.

Two distinctly different methods were investigated in order to achieve this goal, acyloxylation and direct electrochemical hydroxylation. Acyloxylation is the process where radical cations generated at the anode undergoes nucleophilic attack by acetate anions. The resulting aromatic acetates so produced can then be hydrolysed to t

Binocular rivalry is the perceptual consequence of dichoptic input which is not congruent between both visual inputs. There is some evidence, both theoretical and empirical, that the perception of binocular rivalry is mediated by interactions between binocular neurones, rather than by interactions between monocular neurones. This evidence suggests also a model of perception which predicts binocular rivalry as a consequence of normal interactions between binocular neurones in a retinotopic array. This model accounts for rivalry without postulating any additional interconnections beyond t
