The stereoselective Pictet-Spengler reaction and studies towards the total synthesis of ajmaline
Thesis
(2013). The stereoselective Pictet-Spengler reaction and studies towards the total synthesis of ajmaline

Due to their extensive and important medicinal properties, the indole alkaloids are an important class of natural products. A key step towards the total synthesis of indole alkaloids is the diastereoselective Pictet-Spengler reaction, which has enabl...

Steam reforming of methane over alumina supported nickel catalysts: Influence of calcination temperature, gold doping and sulfur addition
Thesis
catalysts: Influence of calcination temperature, gold doping and sulfur addition

Alumina supported nickel and gold-doped nickel catalysts have been investigated for their use as hydrocarbon steam reforming catalysts. The influence of calcination temperature during preparation has been investigated using a variety of techniques in...

High-resolution studies of massive young stellar objects in the Magellanic Clouds
Thesis
(2017). High-resolution studies of massive young stellar objects in the Magellanic Clouds

This thesis presents sub-arcsecond resolution observations of massive Young Stellar Objects (YSOs) in two satellite galaxies of the Milky Way, the Magellanic Clouds. With metallicities of »0.5 and »0.2 Z¯ for the Large Magellanic Cloud (LMC) and Smal... Read More about High-resolution studies of massive young stellar objects in the Magellanic Clouds.

Discovery and characterisation of transiting extra-solar planets with the Wide Angle Search for Planets (WASP) survey
Thesis
(2017). Discovery and characterisation of transiting extra-solar planets with the Wide Angle Search for Planets (WASP) survey

In July of 2012 the WASP-South instrument was modified to allow it to collect data on brighter stars. This change was motivated by the dearth of planets known to orbit bright hosts in the southern hemisphere and the depth of study possible for HD2094...

Catalytic reforming of biogas using nickel based perovskite materials
Thesis
Evans, S. E. (2017). Catalytic reforming of biogas using nickel based perovskite materials

The utilisation of biogas as an energy source or as a feed stock for the chemical industry would help to lower the present wasteful and environmentally unfriendly venting of greenhouse gases to the atmosphere. One obstacle to this becoming a reality... Read More about Catalytic reforming of biogas using nickel based perovskite materials.

Secondary electron emission properties and characteristic energy losses from some metals
Thesis
Thomas, S. (1967). Secondary electron emission properties and characteristic energy losses from some metals

Secondary electron emission yield and characteristic energy losses from a number of metals have been measured in the present investigation. Owing to the known adverse effects of poor vacuum conditions and any consequent contamination of the surface o...
