The synthesis and photochemical behaviour of benztropones and related compounds
Thesis
(1984). The synthesis and photochemical behaviour of benztropones and related compounds

Our aim was to identify the possible factors which controlled the photochemical reactions of benztropones or more widely , annulated tropones,by synthesising benztropones with electron-donating and electron-withdrawing substituents on the benzene rin...

Laser Writing of the Electronic Activity of Nitrogen and Hydrogen Atoms in Gallium Arsenide
Thesis
(2011). Laser Writing of the Electronic Activity of Nitrogen and Hydrogen Atoms in Gallium Arsenide

In this study, we use a focussed laser beam to control the electronic activity of N- and H-atoms in a dilute nitride Ga(AsN)/GaAs quantum well (QW). We find that the laser can be used to dissociate N-H complexes in hydrogenated Ga(AsN) thus enabling...

Studies on the analysis of ecdysteroids and on the seasonal variation of the moulting hormones of the barnacle, Balanus balanoides
Thesis
(1984). Studies on the analysis of ecdysteroids and on the seasonal variation of the moulting hormones of the barnacle, Balanus balanoides

The separation properties of a number of ecdysteroids were examined. The ecdysteroids themselves were separated by thin layer and reverse phase thin layer chromatography. Trimethylsilyl ethers of the ecdysteroids were prepared by reaction with trimet...

Synchrotron x-radiation crystallographic studies of 6-phosphogluconate dehydrogenase from Bacillus stearothermophilus
Thesis
(1984). Synchrotron x-radiation crystallographic studies of 6-phosphogluconate dehydrogenase from Bacillus stearothermophilus

The synchrotron X-radiation crystallographic study of the enzyme 6-phosphogluconate dehydrogenase (6-phospho-D gluconate NADP+ oxidoreductase (decarboxylating), EC 1.1.1.44) extracted from Bacillus stearothermophilus is reported. This crystallographi... Read More about Synchrotron x-radiation crystallographic studies of 6-phosphogluconate dehydrogenase from Bacillus stearothermophilus.

X-ray fibre diffraction studies on the polymorphism of DNA and its synthetic analogues
Thesis
(1983). X-ray fibre diffraction studies on the polymorphism of DNA and its synthetic analogues

The known conformations of DNA are b r ie fly reviewed. Methods which are developed and used to prepare DNA fibres are described.
A left-handed model having 8 7 symmetry has been proposed in an attempt to explain the D-DNA diffraction pattern.
Co... Read More about X-ray fibre diffraction studies on the polymorphism of DNA and its synthetic analogues.
