Synthesis, characterisation and antibacterial activity of substituted 2-quinoline thiosemicarbazones.
(2017)Fifteen quinoline-2-thiosemicarbazone hybrid derivatives were synthesised in a three step reaction involving formation of the quinoline, oxidation of the 2-methyl group and condensation to the thiosemicarbazones. The ... -
A kinetic and mechanistic study of cyclic amine functionalized platinum(II) complexes with bio-relevant nitrogen nucleophiles.
(2018)In this study, four square-planar platinum(II) complexes were synthesized namely C1S1, C2S1, C3S1 and C4S1. The novel platinum(II) complex (C4S1) was synthesized using methods detailed in Chapter 4 and characterized using ... -
Calibration techniques for 21-cm experiments with application to HERA: quasi-redundant calibration analysis.
(2018)Upcoming 21 cm observations promise to open a new window in our understanding of the universe from the epoch of recombination down to redshift of z 1. However, measurements of 21 cm signals come at a high cost since ... -
Metallic nanoparticle-graphene quantum dot nanocomposites for the electrochemical detection of methyl parathion.
