(University of the Western Cape, 2014)Spinel lithium manganese oxide (LiMn2O4), for its low cost, easy preparation and nontoxicity, is regarded as a promising cathode material for lithium-ion batteries. However, a key problem prohibiting it from large scale ... -
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 ... -
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

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 ... -
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 ... -
Microfluidic paper based electrochemical sensing devices
(University of the Western Cape, 2019)Microfluidic paper based electrochemical sensing devices (μPEDs) provides a new way for point of care testing (POCT). μPEDs offer an inexpensive, portable, easy to use technology too monitor the environment and diagnose ... -
Microwave synthesis of the Schiff base metal-ligand complexes with Cu and Ni centres
(University of Western Cape, 2021)Nitric oxide (NO) plays a vital role as a biological messenger in biological systems. However, NO detection and quantification have always posed significant complications. There is, therefore, a need to develop new materials ... -
A modified Adams fusion method for the synthesis of binary metal oxide catalysts for the oxygen evolution reaction
(University of Western Cape, 2020)The majority of the global energy is sourced from conventional fossil fuels. The high demand for energy is accelerating along with the depletion of these fossil fuels. Hence, the shift to renewable energy sources and ... -
Molecularly imprinted polymers for detection of volatile organics associated with fuel combustion
(University of the Western Cape, 2018)Pollutants such as polycyclic aromatic hydrocarbons (PAHs) are known for their toxic effects which may lead to the cause of degenerative diseases in both humans and animals. PAHs are widespread in the environment, and may ... -
