Long-range transport clusters, fine particulate matter (PM2.5) and soot concentrations of air masses in Cape Town, South Africa
(University of the Western Cape, 2018)Ambient air pollution is the biggest environmental threat to human health. According to the World Health Organisation (WHO), ambient air pollution kills millions of people worldwide every year. Airborne particulate matter ... -
Membrane module development for water recovery from humid gas
(University of the Western Cape, 2020)Over the past 5 years, South Africa has been experiencing a severe drought. This has caused industrial and agricultural processes, to compete for a limited supply of water. Since the economy relies mostly on agricultural ... -
Mercaptobenzothiazole-on-Gold Biosensor Systems for Organophosphate and Carbamate Pesticide Compounds
(University of the Western Cape, 2007)This study firstly reports the development, characterisation, and application of thick-film acetylcholinesterase (AChE) biosensors based on a gold electrode modified with a mercaptobenzothiazole (MBT) self-assembled monolayer ... -
Metal complexes based on monomeric and dendrimeric pyrrole-imine ligands as catalytic precursors
(University of the Western Cape, 2007)Over the recent past, organometallic chemistry has grown and the impact of catalytic applications in various chemical technologies has rapidly evolved from the realm of academic laboratories into full-scale industrial ... -
Metal modified mesoporous ZSM-5 as catalysts for the oligomerization of 1- hexene
(University of Western Cape, 2021)The use of diesel engines in vehicles and heavy machinery throughout the world has been slowly increasing in the past few decades. This has led to high demand for diesel and gasoline with high octane number. Diesel and ... -
Metal nanoparticle modified polysulfone membrane for water treatment
(University of the Western Cape, 2013)Membrane separation processes have been widely applied in the treatment of wastewater with polysulfone (PSF) polymer membrane being the most frequently used in ultrafiltration of wastewater due to its chemical and structural ... -
Metallic nanoparticles with polymeric shell: A multifunctional platform for application to biosensor
(University of the Western Cape, 2018)Tuberculosis (TB) is an airborne disease caused by Mycobacterium tuberculosis (MTB) that usually affects the lungs leading to severe coughing, fever and chest pains. It was estimated that over 9.6 million people worldwide ... -
Metallodendrimers as catalysts for C-C coupling reactions
(2011)In this work, we describe the synthesis of ferrocenylimine and G1 dendrimeric N,N′ ligands, and their palladium(II) complexes. The ligands L1 – L4 were synthesized following Schiff base condensation reactions. The ... -
Method development for selective recovery of rare earths elements from phosphogypsum waste
(University of Western Cape, 2021)The need for rare earth elements (REEs) in current technologies has motivated countries with high imports dependency to search for alternatives sources. Several studies have been carried out to investigate the feasibility ... -
Microfluidic graphenised-paper electroanalytical devices (μGPED) for adsorptive cathodic stripping voltammetric detection of metal contaminants
(University of the Western Cape, 2017)The need for clean, non-toxic drinking water supplies, free of pollutants and metal contamination is vital in impoverished areas and the developing world alike. With this in mind, the development of accurate, inexpensive, ... -
