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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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, ...

2, 2, 6, 6-Tetramethylpiperidine-N-oxyl radical (TEMPO) is a stable nitroxyl radical, as well as a highly efficient selective oxidation catalyst. It can efficiently catalyze the selective oxidation of C6 primary hydroxyl ...

Glycerol is considered as the major waste from biodiesel production since every 1L of biodiesel produced is accompanied by 0.1 L of glycerol by-product. Utilizing this waste as a biorefinery feedstock will not only ...

Reduced graphene oxide (RGO) supported cobalt based catalysts with or without rhodium promotion, Rh-Co/RGO (RCG) and Co/RGO (CG), were successfully synthesized and evaluated in both Fischer Tropsch synthesis (FTS) and ...
