Genetic fuzzy rule extraction for optimised sizing and control of hybrid renewable energy hydrogen systems
(Elsevier, 2020)A major challenge related to the design of a hybrid renewable energy hydrogen system is which energy sources to include and at what capacity, for regionally different potentials of renewable energy and hydrogen demand. In ... -
Prevalence of dyslipidaemia among type 2 diabetes mellitus patients in the Western Cape, South Africa
(MDPI, 2020)Dyslipidaemia, an irregular aggregate of lipids in the blood is common in diabetes and cardiovascular disease sufferers. A cross-sectional study on the prevalence of dyslipidaemia was performed among type 2 diabetes mellitus ... -
Performance evaluation and kinetic modeling of down-flow high-rate anaerobic bioreactors for poultry slaughterhouse wastewater treatment
(Springer, 2020)In this study, the treatment of poultry slaughterhouse wastewater (PSW) was evaluated using two new down-flow high-rate anaerobic bioreactor systems (HRABS), including the down-flow expanded granular bed reactor (DEGBR) ... -
Equilibrium, kinetic, and thermodynamic studies of lead ion adsorption from mine wastewater onto MoS2-clinoptilolite composite
(Elsevier, 2020)This work explored the potential of clinoptilolite, molybdenum sulphide (MoS2), and MoS2-clinoptilolite composite in lead (Pb) removal from aqueous medium and industrial mining wastewater. MoS2-clinoptilolite composite was ... -
On the influence of methanol addition on the performances of PEM fuel cells operated at subzero temperatures
(Elsevier, 2020)The storage and the operation of proton exchange membrane fuel cells (PEM FCs) at subzero temperatures result in the ageing and degradation of membrane-electrode assemblies (MEAs). In this study, we investigated the effect ... -
Investigation of structural and optical properties of biosynthesized Zincite (ZnO) nanoparticles (NPs) via an aqueous extract of Rosmarinus officinalis (rosemary) leaves
(Cambridge Univ Press, 2020)Biosynthesized Zincite nanoparticles have been successfully demonstrated by a completely green process mediated aqueous extract of rosemary leaves acting as both reducing and stabilizing agents and zinc nitrate hexahydrate ... -
Development of a low purity aluminum alloy (Al6082) anodization process and its application as a platinum-based catalyst in catalytic hydrogen combustion
(Elsevier, 2020)In this study, we present a process to prepare a Pt/anodized aluminum oxide (AAO) catalyst for catalytic hydrogen combustion applications using low cost and low aluminum (Al) purity Al6082 alloy (97.5% Al) as the substrate. ... -
Temperature profile mapping over a catalytic unit of a hydrogen passive autocatalytic recombiner: an experimental and computational fluid dynamics study
(ACS, 2020)Passive autocatalytic recombiners (PARs) are used for the removal of accidentally released hydrogen inside confined spaces. The high catalyst surface temperature is an important safety issue to be considered in the use of ... -
Recovery of iron nanoparticles from mine wastewater using plant extracts of Eucalyptus Globulus, Callistemon Viminalis and Persea Americana
(MDPI, 2020)Mine wastewater (MW) is often rich in heavy metals that can have measurable effects on humans. The storage and treatment of MW remains a challenge for most mining companies. Iron (Fe) in MW was removed by using extracts ... -
Feasibility of electro-reduction of U(VI) in oxalic acid using an electrolytic CEM-separated cell
(Springer, 2020)The feasibility of electrolytic stripping of U(VI) using an electrolytic separation cell with anode and cathode compartments, separated by a cation exchange membrane (CEM), was investigated as a possible final step in a ... -
Condition monitoring of lubricant shortage for gearboxes based on compressed thermal images
(Springer, 2020)Condition monitoring of gearboxes is a crucial task because gearboxes are essential power transmission components whose failure can lead to a catastrophic breakdown of machines. The common faults of a gearbox system, such ... -
Comparison of the performance and durability of PEM fuel cells with different Pt-activated microporous layers
(Elsevier, 2020)We report on a comparative study of the performance level of H2/O2 PEM fuel cells in which the catalytic layers containing Pt nanoparticles were deposited on the microporous layer side of gas diffusion electrodes, using ... -
Development of an integrated model for absorption of sulphur dioxide in limestone slurry
(Elsevier, 2021)The aim of this study is to develop an integrated model for SO2 absorption into limestone slurry consisting of four sub-models, namely, absorption of SO2; desorption of CO2; dissolution of limestone and crystallization of ... -
Stress tolerance assessment of dibenzyltoluene-based liquid organic hydrogen carriers
(RSC, 2020)Hydrogen production from charged liquid organic hydrogen carrier (LOHC) systems is always a trade-off between the molecule's storage capacity and the stability over the numerous charging/discharging cycles. This is because ... -
Improving dynamic microgrid modelling through the use of synchronised field data
(IEEE, 2020)Simulation during the design and operation of microgrids should include dynamic phenomena that would be a result of the unpredictable variation in renewable generation and loading. Detailed modelling of different components ... -
Two-dimensional graphene-HfS(2) van der Waals heterostructure as electrode material for alkali-ion batteries
(RSC, 2020)Poor electrical conductivity and large volume expansion during repeated charge and discharge is what has characterized many battery electrode materials in current use. This has led to 2D materials, specifically multi-layered ... -
Revising the dark fermentative H-2 research and development scenario: an overview of the recent advances and emerging technological approaches
(Elsevier, 2020)The indiscriminate use of fossil fuels has led to several challenges such as greenhouse gas emissions, environmental degradation, and energy security. Establishment of clean fuels is at the forefront of science and innovation ... -
Ultrasonic assisted amaranth stem pretreatment for bio-ethanol production
(ETA-Florence Renewable Energies, 2015)An investigation was undertaken to determine the effect of ultrasound on enzymatic hydrolysis rate and enhanced bioethanol yields. Compositional analysis of the feedstock reveals that amaranth lignocellulose contains 36.35% ... -
In-situ biodiesel production from sunflower seeds using liquefaction
(ETA-Florence Renewable Energies, 2015)One of the most expensive steps in the bio-diesel value chain is the extraction of oil from the seeds. Simultaneous extraction and transesterification will lower the overall capital costs of the process while enhancing ...
