The p53 gene is a well-known tumour suppressor gene, shown to be dysfunctional in more than 50% of human malignancies. The cellular significance of this oncogene is evident in a series of diverse cellular antiproliferation ...
South Africa is classified as a water-stressed country and is faced with widespread water scarcity. Water scarcity is worse in rural areas of the country where a third of the population still reside. This is due to low ...
Abstract
Background
Cellulose polymers with multidentate chelating functionalities that have high efficiency for toxic metal ions present in water were designed, synthesized, ...
Metal-organic frameworks (MOFs) are gaining popularity as a new electrode material for
supercapacitor applications, due to their large specific surface area, excellent tunability and unique
pore characteristics. Yet, ...
This thesis reports on the synthesis and characterisation of various types of oxidised multiwalled carbon nanotubes (O-MWCNTs) modified polymeric membranes. These OMWCNT modified polymeric membranes were then assessed in ...
Laser application in the field of biological and medical sciences has significantly grown, thereby
strengthening the field of Biophotonics. Research conducted in Biophotonics focuses on the concept
of using light especially ...

Abstract
This study aims to compare iso-rank vitrinite-rich and inertinite-rich coal samples to understand the impact of coal-forming processes on pyrolysis chemistry. A medium rank C bituminous coal was ...
Specially prepared 2-amino-5-bromo-3-iodoacetophenone and 5-bromo-2-hydroxy-3
iodoacetophenone were subjected to Claisen-Schmidt aldol condensation with benzaldehyde derivatives followed by sequential and/or one-pot ...
Restriction endonucleases are a group of enzymes that cleave DNA at or around specific sequences, which are typically palindromic. A fosmid library was constructed from a metagenome isolated from soil from the Kogelberg ...
The use of veterinary drugs continues to be a challenge since some farmers use drugs for medicinal purposes, while others use them as growth promoters without observing the set withdrawal times. In emerging economies, ...
Focus of this study was on the development of one of the faster, simpler, cost effective and environmentally friendly sample pre-treatment techniques which employs a supported liquid membrane, in this case a Hollow-fiber ...
Emerging contaminants (EC) are unregulated substances that have entered the environment for as long as they have been produced through human activities. Within the ECs family, pharmaceuticals and personal-care products ...
A dispersive liquid-liquid microextraction (DLLME) method has been developed, optimized and validated for the extraction of seven beta-agonists (Cimaterol, Cimbuterol, Clenproperol, Clenbuterol, Ractopamine, Isoxsuprine ...
Natural organic matter (NOM) is a diverse blend of decomposed animal and plant material
found in different natural water sources. Due to its large and complex structure, NOM is
difficult to both remove and characterize ...
Seventeen novel osmium cymene complexes with O,O′- and P,P′-chelating ligands as well as N- and P-monodentate ligands are reported. The osmium cymene complexes were synthesised and characterised by spectroscopic techniques ...
The FT-Raman techniques were developed to quantify reactions that
follow on mixing aqueous solutions of bis-(1,3-diaminopropane)diaquacobalt(
III) ion ([Co(tn)2(0H)(H20)]2+) and p-nitrophenylphosphate
(PNPP).
For the ...
An environmentally friendly, rapid and cost effective analytical procedure based on dispersive liquid-liquid microextraction was developed for the determination of six tetracyclines (TCs) in meat destined for human ...
Routes to mononuclear Os(II) and Os(0) cluster complexes containing P-donor ligands (PR3, PP) were studied using the osmium salts Y2[OsX6] (Y = NH4, K; X = Cl, Br, I) as precursors. Carbonylation of the precursors and ...
Natural products or traditional medicine has been used for centuries to treat various ailments by mankind. The World Health Organization estimates that in recent times 80% of people in emerging economies rely on traditional ...
The known 2-aryl-6,8-dibromo-2,3-dihydroquinolin-4(1H)-ones 122 were dehydrogenated
using thallium(III) p-tolylsulfonate in dimethoxyethane under reflux to afford the 2-aryl-6,8-dibromoquinolin-4(1H)-ones 136. Palladium-catalyzed ...
