The effects of capping agents on the synthesis of magnetic-luminescent Fe₃O₄ -InP/ZnSe nanocomposite material
(University of the Western Cape, 2015)Magnetic luminescent nanoparticles of an iron oxide (Fe₃O₄) superparamagnetic core and an indium phosphide/zinc selenide (InP/ZnSe) quantum dot shell are reported. The magnetic nanoparticles (MNP’s) and quantum dots (QD’s) ... -
The effects of carbon-based nanoparticle surface functionalization on immune responses
(University of the Western Cape, 2022)Nano-based technologies are highly desired for the unique properties achieved through size restrictions. Nanoparticles (NPs) achieve a higher surface-to-volume ratio during synthesis. As a result there is a greater rate ... -
Effects of catchment management on physical river condition, chemistry, hydrogeomorphology and ecosystem service provision in small coastal rivers of the Western Cape
(University of the Western Cape, 2019)River systems are by nature complex and dynamic systems, which vary in structure and therefore function, and are closely connected to their landscapes. The primary aim of this thesis was to develop a systems operational ... -
Effects of clay minerals on the petrophysical properties of sandstone reservoirs from the Offshore Pletmos Basin, South Africa
(University of the Western Cape, 2019)With the latest advancements in the Pletmos Basin it is imperative to understand and study how sandstone reservoirs are affected by clay minerals. Clay minerals are an influential component in sandstone reservoirs worldwide ... -
