(Academic Journals, 2012-09)The Olifants river has been described as one of the most environmentally polluted rivers in Southern Africa, particularly in the upper catchment. Untreated water from the catchment may be used for many purposes including ...
-
(2012-10)A quantitative microbial risk assessment of water in the upper Olifants River catchment showed that sections of the catchment are highly contaminated with faecal indicator bacteria and pathogenic micro-organisms and that ...
-
(Taylor & Francis, 2014-12)The effects of a decomposing cyanobacteria bloom on water quality and the accumulation of microcystin-LR equivalent toxin in fish at Loskop Dam were studied in May 2012. Enzyme-linked immunosorbent assay [ELISA] was used ...
-
(SAGE Publications Ltd, 2016-11)Disposable, low-cost microfluidic cartridges for automated blood cell counting applications are presented in this article. The need for point-of-care medical diagnostic tools is evident, particularly in low-resource and ...
-
(American Institute of Physics (AIP), 2014-09)We present a novel use for channel structures in microfluidic devices, whereby two two-phase emulsions, one created on-chip, the other off-chip, are rapidly mixed with each other in order to allow for the coalescence of ...
-
(Wiley, 2017-08)We present a simple microfluidic system for rapid screening of Escherichia coli (E. coli) O157:H7 employing the specificity of immunomagnetic separation (IMS) via immiscible filtration assisted by surface tension (IFAST), ...
-
(European Cells & Materials Ltd, 2010)Microfluidics is a multi-disciplinary field that deals with the behaviour, control and manipulation of fluids constrained to sub-millilitre volumes. It is proving to be a useful tool for biological studies, affording ...

-
(Journal of Optoelectronics and Advanced Materials, 2012-12)Surface modification of titanium alloy (Ti-6Al-4V) was made using a Rofin Sinar 4 kW Nd: YAG laser. A laser multi-track 50% overlapping process was employed to produce Zr and Zr-TiC metal matrix composite (MMC) coatings ...
-
(Elsevier, 2016-02)The purpose of this investigation was to determine whether shellac, a naturally occurring material with enteric properties, could be processed in supercritical CO2 (sc-CO2) using the particles from gas saturated solution ...
-
(CSIR, 2008-11)Microreactors are miniature reactors for carrying out chemical reactions. CSIR Biosciences has been investigating the production of biodiesel using various sources of vegetable oils, for example, soya, sunflower, canada, ...
-
(John Wiley & Sons, Inc, 2015-03)Hydroxyapatite (HAP) is the most researched calcium phosphate material in the field of biomaterials to be used for bone re-engineering applications; given its attractive properties. Plasma spraying is the best available ...
-
(Springer Verlag (Germany), 2014-02)Bio-composite coatings of 20 wt.%, HAP and 80 wt.%, HAP were synthesized on Ti-6Al-4V substrates using LACS technique. The coatings were produced with a laser power of 2.5 kW, powder-laser spot trailing by 5 s. The coatings ...
-
(Deutsche Gesellschaft fur Materialkunde eV, 2009-10)One of the most effective ways of improving the fuel consumption and hence reducing the environmental impact of transport vehicles is via reduction in mass. This has resulted in the increased use of magnesium (Mg) to reduce ...
-
(Elsevier, 2014-04)Un-doped and Tb(Sup3+) doped ZnO nanocrystals with different concentrations of Tb(Sup3+) were synthesized by a sol–gel method and their photoluminescence (PL) properties were investigated. The successful incorporation of ...
-
(Springer, 2017-11)The enhancement of the tribological properties of titanium (Ti-6Al-4V) has been the subject of wide range research over the years. The constraints associated with Ti-6Al-4V in severe tribological conditions due of its low ...
-
(2007-07)Heat input plays an important role in the microstructural development of 12%Cr martensitic stainless steel. The microstructure of low-C 12%Cr martensitic stainless steel resulting from laser cladding was investigated. For ...
-
(Elsevier, 2014-09)Multiple track laser alloying is characterised by additional heat treatment and differences in the amount of powder deposited at the overlap regions. These result in different microstructural and phase evolution at these ...
