With the growing demand for energy storage and conversion technologies, porous
carbon-based materials (PCMs) have garnered widespread attention due to their
excellent electrical conductivity, high surface area (SSA), and ...
This thesis aims at understanding and formalising human capabilities in enterprise architecture (EA). It begins by justifying why it is important for EA research and practice to consider human capabilities, and then proceeds ...
The purpose of this study was to analyse the amount of municipal solid waste disposed at various landfill sites in the east of Johannesburg. As a resident residing in the east of Johannesburg, it was of interest to me to ...
Normally, non-biodegradable solid waste material produced in South Africa is disposed off through landfilling, intriguingly, the country has limited landfill space and a high demand for affordable solid waste material for ...
Natural organic matter (NOM) removal is one of the challenges encountered by water treatment utilities in water treatment. NOM is found naturally in all surface waters and consists of compounds with complex structures ...
The water quality of South African rivers is greatly impacted by insufficiently treated
wastewater effluents (de facto reuse). Although de facto reuse serves as an alternative
water supply it poses potential threats to ...
The Vaalkop water treatment works (WTW) abstracts water from the Vaalkop Dam, which is situated in the Crocodile West/Marico Water Management Area of South Africa. The bulk of the inflow into the dam is through a canal fed ...
Acid mine drainage (AMD) is a serious water pollutant that contaminates freshwater sources such as rivers, lakes, ground water and even sediments with heavy metals which include Cr(VI), Cd(II) and Pb(II). In this study a ...
The transport industry is one of the biggest contributors to air pollution, with the major air pollutants being COx, NOx, and SOx. SOx is produced by the combustion of the organic sulphur compound found in fuels, e.g. ...
This dissertation examines the structure and properties of chitosan membranes regarding their applicability in fuel cells. The objective of this work is to synthesize a polymer membrane with improved properties such as ...
The thermochemical conversion of waste tires for chemicals and power production is investigated using process synthesis techniques and experimental analysis. Pyrolysis and gasification technologies were evaluated in terms ...
Industrialization has resulted in the introduction of xenobiotics into the environment.
These chemicals have polluted soil, water, and air, causing significant health concerns.
White rot fungi possess the capability to ...
Municipal wastewater pollution in developing countries is a great concern due to partially treated or untreated wastewater. Inflow and Infiltration (I/I) is a challenge in municipalities that receive stormwater as it impacts ...

Abstract
Tannery industries’ effluent contains a high concentration of Cr (VI) which has the potential to affect the environment and public health. Therefore, this study aimed to investigate the optimization ...
Crude oil is an unrefined petroleum which forms because of dead organisms buried under mud over a long period of time (million years). The mud is then converted to sedimentary rocks, which create intense heat and pressure, ...
The aim of this study was to determine the effects of the feedstock composition, such as biomass, polyethylene and their respective blend ratios, -gasifying agents and operating conditions on the product gas composition, ...
Abstract
Due to their outstanding power density, long cycle life and low cost, supercapacitors have gained much interest. As for supercapacitor electrodes, molybdenum nitrides show promising potential. ...
