Antibacterial activity of rationally designed antimicrobial peptides
(Hindawi, 2020)Many infectious diseases are still prevalent in the world’s populations since no effective treatments are available to eradicate them. e reasons may either be the antibiotic resistance towards the available therapeutic ... -
Electrocatalytic sensor devices: (I) cyclopentadienylnickel(II) thiolato Schiff base monolayer self-assembled on gold
(Elsevier, 2004)The fabrication of a self-assembled monolayer (SAM) of a cyclopentadienylnickel(II) thiolato Schiff base compound, [Ni(SC6H4NC(H)C6H4 OCH2CH2SMe)( 5-C5H5)]2 on a gold electrode is described. Effective electronic communication ... -
Ex-situ electrochemical characterization of iro2 synthesized by a modified Adams fusion method for the oxygen evolution reaction
(MDPI, 2019)The development of highly stable and active electrocatalysts for the oxygen evolution reaction (OER) has attracted significant research interest. IrO2 is known to show good stability during the OER however it is not known ... -
Extremophiles in biofuel synthesis
(Taylor and Francis Group, 2010)The current global energy situation has demonstrated an urgent need for the development of alternative fuel sourcesto the continually diminishing fossil fuel reserves. Much research to address this issue focuses on the ... -
Investigation of a dual-band dual radio indoor mesh testbed
(2018)Scalability of community wireless mesh networks in terms of mesh nodes and mobile end-users along with their anticipated usage profile remains unexplored territory. However, conducting such experiments on a live community ... -
A low-cost flow cytometric assay for the detection and quantification of apoptosis using an anionic halogenated fluorescein dye
(Future Science Group, 2008)We describe here a technical improvement of an established colorimetric method used to detect and measure the occurrence of apoptosis in mammalian cells during in vitro cell culture. This assay uses an anionic halogenated ... -
A novel immersive anatomy education system (anat_hub): Redefining blended learning for the musculoskeletal system
(MDPI, 2022)Immersive technologies are redefining ways of interacting with 3D objects and their environments. Moreover, efforts in blended learning have presented several advantages of incorporating educational technology into the ... -
Progress in the use of geospatial and remote sensing technologies in the assessment and monitoring of tomato crop diseases
(Taylor and Francis Group, 2022)With a growing global population and accelerating climatechange, systematic assessment and monitoring of crop diseases isurgently required to ensure food security and production.However, current dietary transitions ... -
Promoting physics and development in Africa
(American Institute of Physics, 2004)To excel in physics research in Africa is to conquer Mount Everest without the aid of additional oxygen. In a continent that lacks the infrastructure of research laboratories, technical support, and so forth, relatively ... -
Remote sensing of land use-land cover change and climate variability on hydrological processes in Sub-Saharan Africa: Key scientific strides and challenges
(Taylor and Francis Group, 2022)The impact of land use land cover (LULC) change and climatevariability on water resources poses as a major threat in semi-aridenvironments, especially in the sub-Saharan Africa. Countries insub-Saharan Africa are vulnerable ... -
Remotely sensed applications in monitoring the spatio-temporal dynamics of pools and flows along non-perennial rivers: A review
(Taylor and Francis Group, 2022)Non-perennial rivers (NPRs) account for more than 50% of the world’s river network and their occurrence is expanding. Some rivers that were previously classified as perennial have evolved to be NPRs in response to climate ... -
Spectral classification, mapping and physical habitat implications of a riparian invasion by Tamarix ramosissima Ledeb. in the Touws River, Klein Karoo, South Africa
(Taylor and Francis Group, 2022)This paper investigates the invasion of a reach of the Touws River by the deciduous alien tree Tamarix ramosissima Ledeb. (Pink Tamarisk, Saltcedar). The objectives of the paper were to investigate ... -
Strategies for information management in education: some international experience
(AOSIS Open Journals, 2013)Background: Recent analysis of the management of information and communications technologies in South African education suggests strongly that there is only limited strategic thinking that might guide policy-makers, school ... -
Students' ontological security and agency in science education - an example from reasoning about the use of gene technology
(Taylor & Francis, 2013)This paper reports on a study of how students' reasoning about socioscientific issues is framed by three dynamics: societal structures, agency and how trust and security issues are handled. Examples from gene technology ... -
Underpotential deposition of SnBi thin films for sodium ion batteries: The effect of deposition potential and Sn concentration
(Elsevier, 2019)Bimetallic SnBi film was deposited on a Cu foil substrate via the electrochemical atomic layer deposition (E-ALD) technique. The deposition attainment of Sn and Bi were investigated using cyclic voltammetry (CV) and ... -
Use of multi-source remotely sensed data in monitoring the spatial distribution of pools and pool dynamics along non-perennial rivers in semi-arid environments, South Africa
(Taylor and Francis Group, 2022)This study explored the use of multi-source remotely sensed data in monitoring the spatial distribution of pools and pool dynamics in two distinct semi-arid sites in South Africa. The factors that control the pool ...
