Synthesis and characterisation of Acylhydrazinatometallomesogens
Previous work at this institute involved the synthesis and characterisation of Ni2 complexes based on the N-alkylideneacylhydrazine ligand. The primary aims of this project were to synthesise and characterise a series of metallomesogens based on the N-allcylideneacylhydrazine ligand by studying the …

The Synthesis and Characterisation of Long-Chain Fatty Acids
The commercial hydrogenation of oils and fats results in the formation of, among other components, geometrical and positional isomers of monounsaturated fatty acids. The view that there may be hazards associated with such oils have occasionally been expressed. Prior to an investigation of the …
