Base-Free Suzuki acylation reactions of sodium (aryl trihydroxyborate) salts: a novel synthesis of substituted aryl ketones.
(2018)Asymmetric biaryl ketones are important building block in organic chemistry since they occur in large number of biological active compounds, natural product, cosmetics as well as in organic synthesis. The aim of this project ... -
Baseline demand responsiveness framework for the conventional grid through appliance scheduling by evolutionary metaheuristics.
(2020)A major problem of many energy environments nowadays, is an obsolete and highly inefficient electricity supply system, the Conventional Grid (CG), characterized by a high peak to average ratio, out of an uncontrollable ... -
Beam generated instabilities in space plasma.
(1999)Electrostatic instabilities associated with a model applicable to the auroral acceleration region consisting of an ion beam, precipitating electrons and stationary background electrons are theoretically investigated. The ... -
Binary and ternary molecules blend bulk heterojunction organic solar cell.
(2015)Bulk heterojunction organic solar cells were prepared and characterized in terms of electrical and optical properties of the photosensitive medium. Two cases of organic solar cells were developed in this investigation ... -
Bioactive sesquiterpenoids from dicoma anomala subsp. gerrardii
(2008)Through South Africa’s first collaborative project between a large scientific organisation, the Council for Scientific and Indust rial Research (CSIR), and the Traditional Healer’s Committee, Dicoma anomala was identified ... -
Biochemical-physical mechanisms of light-tissue interactions.
(2021)Optical tissue phantom samples simulating the optical properties of the human prostates and brain tissues were fabricated. The experimental set-up was designed to be cost-effective but reliable, allowing for convenience ... -
Bis (pyrazolyl) pyridine Cu (II) and Zn (II)complexes : syntheses, molecular structures and polymerization reactions of ε-Caprolactone and lactides.
(2015)Reactions of 2,6-bis((3,5-dimethyl-1H-pyrazol-1-ylmethyl)pyridine (L1) and 2,6-bis(3,5-dimethyl-N-pyrazolyl)pyridine (L2) ligands with Zn(II) and Cu(II), acetates and carboxylates (benzoates, 2-chlorobenzoate, & 2-bromobenzoate) ... -
Boron- and nitrogen-doped carbon nanotubes : synthesis, characterization and application in solar cells.
(2015)Abstract available in PDF file. -
The Brix-Free water capacity and sorption behaviour of fibre components of sugar cane (Saccharum officinarum).
(2008)Milling data from sugar factories in Mauritius were examined from 1960 to 2004 to assess the trend in the quality of cane received at mills and the change in factory performance. A deterioration in overall quality was ... -
Bulk heterojunction organic solar cell.
(2014)The low material costs and the ease fabrication procedures of organic solar cells has earned them too much interest from scientists all over the world. Much of the e orts were given to the improvement of the power ... -

(2016)Abstract available in PDF file. -
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 ... -
Capillary electrophoresis and related techniques for the analysis of fresh water algal toxins.
(1997)As cyanobacteria (also known as blue green algae) produce a range of cyclic peptides which are highly toxic, capillary electrophoresis and associated techniques have been investigated to assess their applicability ... -

The catalysed activation of n-octane over iron modified hydroxyapatites.
(2014)This research effort investigated the activation of n-octane by oxidative dehydrogenation and dehydrogenation over iron substituted and iron supported on hydroxyapatite catalysts. Pure hydroxyapatite and iron substituted ... -
Characterisation and quantification of wood extractives and their impact on pitch.
(2011)The aims of this study were to characterise and quantify wood extractives in E. grandis and E. nitens and determine the impact of wood extractives on pitch formation. Initially a comparison was made with individual solvent ... -
Characterisation and quantum application of plasmonic waveguides.
(2016)Plasmonics o ers sub-di raction confinement of light, which a ords enhanced coupling to emitter systems (e.g. quantum dots). This feature makes possible a range of on-chip quantum photonic components - most notably ... -
