Hydrogen selective properties of cesium-hydrogensulphate membranes
(University of the Western Cape, 2006)
The production procedure of a CsHS04-Si02 composite membrane was optimized in order to obtain the highest possible H2:C02 and H2:C~ Idea selectivity permeance. The optimized membrane preparation procedure led to the ...
Evaluation of the leachate chemistry and contaminants attenuation in acid mine drainage by fly ash and its derivatives
(University of the Western Cape, 2006)
The mining industry in South Africa has a huge potential to impact negatively on the environment. Negative impacts include generation of reactive tailings and acid mine drainage (AMD). AMD is highly acidic (pH 2-4), ...
Homogeneity of nanophase electrocatalysts supported on mesoporous materials
(University of the Western Cape, 2006)
Synthesis and characterization of nanofluids for cooling applications
(University of the Western Cape, 2006)
Low thermal conductivity is a primary limitation in the development of energy-efficient heat transfer fluids that are required in numerous industrial sectors. Recently submicron and high aspect ratio particles (nanoparticles ...
Phytochemical studies of Helichrysum patulum
(University of the Western Cape, 2006)
Since Helichrysum is known by the indigenous people of Africa for therapeutic properties, such as against colds, flu and wounds, the aim of this study was to focus on the patulum species found predominantly in the Western ...
The electrogeneration of hydroxyl radicals for water disinfection
(University of the Western Cape, 2006)
This study has shown that OHË radicals can be generated in an Fe/O2 cell from the electrode products via Fenton’s reaction and used for water disinfection. The cell system in which the experiments were carried out ...
Hydrogen selective properties of cesium-hydrogensulphate membranes
(University of the Western Cape, 2006)
Over the past 40 years, research pertaining to membrane technology has lead to the development of a wide range of applications including beverage production, water purification and the separation of dairy products. For the ...
Composite low temperate hydrogen storage material on the basis of iron-titanium alloy ; synthesis and structure
(University of the Western Cape, 2006)
It is widely believed that hydrogen will within a few tens of years become the means of storing and transporting energy. The reason is the depletion of hydrocarbons and the
relatively facile production of hydrogen from ...
Preparation and characterization of highly active nano pt/c electrocatalyst for proton exchange membrane fuel cell
(University of the Western Cape, 2006)
Catalysts play an essential role in nearly every chemical production process. Platinum supported on high surface area carbon substrates (Pt/C) is one of the promising candidates as an electrocatalyst in low temperature ...
