Towards the development of a novel bipolar-based battery in aqueous electrolyte: Evaluation of the electrochemical properties of NiCu based hydroxide electrodes fabricated on Ni–mesh and graphite composite current collectors
(Journal of Energy Storage, 2022)The use of bipolar electrodes in rechargeable batteries can improve specific power, simplify cell design, and reduce manufacturing costs. However, bipolar-based batteries still suffer from many drawbacks. Therefore, ... -
Trace elements risk assessment for consumption of wild mussels along South Africa coastline
(Elsevier, 2021)The study aimed to contribute to the scarce data on concentrations in the soft tissue of wild mussels growing in coastal cities of South Africa. The intake of 26 micro and macroelements was estimated. The mass fractions ... -
Tracking research trends and hotspots in sperm DNA fragmentation testing for the evaluation of male infertility: a scientometric analysis
(Reproductive Biology and Endocrinology, 2019)Background: This article describes the research trends in sperm DNA fragmentation (SDF) over the past 20 years (1999–2018) using a scientometric approach. Methods: A stepwise approach was adopted to retrieve scientometric ... -
Transcriptomic analysis reveal novel genes with sexually dimorphic expression in the zebrafish gonad and brain
(Plosone, 2008)Our knowledge on zebrafish reproduction is very limited. We generated a gonad-derived cDNA microarray from zebrafish and used it to analyze large-scale gene expression profiles in adult gonads and other organs. We have ... -
Transcriptomic profile of mycobacterium smegmatis in response to an imidazo[1,2-b][1,2,4,5]tetrazine reveals its possible impact on iron metabolism
(Frontiers Media, 2021)Tuberculosis (TB), caused by the Mycobacterium tuberculosis complex bacteria, is one of the most pressing health problems. The development of new drugs and new therapeutic regimens effective against the pathogen is one ... -
Transcriptomics of the Rooibos (Aspalathus linearis) Species Complex
(MDPI, 2020)Rooibos (Aspalathus linearis), widely known as a herbal tea, is endemic to the Cape Floristic Region of South Africa (SA). It produces a wide range of phenolic compounds that have been associated with diverse health-promoting ... -
Transfer of Madagascan species of Gnidia L. to Lasiosiphon Fresen. (Thymelaeaceae: Thymelaeoideae)
(South African Journal of Botany, 2017)Thirteen of the fourteen Malagasy species of Gnidia are transferred to Lasiosiphon following its re-instatement based on systematic studies of the Thymelaeoideae. New combinations are made for five of the species and the ... -
Transformation between phreatic water and soil water during freeze–thaw periods
(MDPI, 2018)During freeze–thaw periods, the exchange between shallow groundwater and soil water is unusually strong and bidirectional, which causes soil salinization and affects the accuracy of water resources assessment. The ... -
Transformation of fly ash based nanosilica extract to BEA zeolite and its durability in hot liquid
(Elsevier, 2020)Power generation in South Africa relies heavily on the combustion of coal and during this process, coal fly ash (CFA) is generated as by-product, which raises several environmental issues. The transformation of CFA into a ... -
Transforming RNA-Seq gene expression to track cancer progression in the multi-stage early to advanced-stage cancer development
(Public Library of Science, 2023)Cancer progression can be tracked by gene expression changes that occur throughout early-stage to advanced-stage cancer development. The accumulated genetic changes can be detected when gene expression levels in advanced-stage ... -
Transhumance pastoralism in West Africa – its importance, policies and challenges
(African Journal of Range & Forage Science, 2023)The Economic Community of West African States (ECOWAS) recognises transhumance pastoralism as a beneficial livestock production system that can contribute to food security together with economic and political stability. ... -
Transitioning towards a circular bioeconomy in South Africa: Who are the key players?
(Academy of Science of South Africa, 2022)The transition towards a circular economy is becoming a priority in many countries globally. However, the circular bioeconomy has received relatively less attention. In South Africa, the valorisation of organic waste is a ... -
Transport inequalities and the adoption of intelligent transportation systems in Africa: A research landscape
(MDPI, 2021)Intelligent Transportation Systems (ITS), also known as Smart Transportation, is an infusion of information and communication technologies into transportation. ITS are a key component of smart cities, which have seen ... -
Trapum discovery of 13 new pulsars in ngc 1851 using meerkat
(Hans Publishers, 2022)We report the discovery of 13 new pulsars in the globular cluster NGC 1851 by the TRAPUM Large Survey Project using the MeerKAT radio telescope. The discoveries consist of six isolated millisecond pulsars (MSPs) and seven ... -
The trapum l-band survey for pulsars in fermi-lat gamma-ray sources
(Oxford University Press, 2023)More than 100 millisecond pulsars (MSPs) have been discovered in radio observations of gamma-ray sources detected by the Fermi Large Area Telescope (LAT), but hundreds of pulsar-like sources remain unidentified. Here, we ... -
Trauma and PTSD in prisons and corrections
(Elsevier, 2023)Post-traumatic stress disorder (PTSD), and particularly complex PTSD, is over-represented in prisons and corrections. In this interview with Jean-Pierre Bouchard, Thomas Fovet, Cle ́ ment Villa, Bettina Belet, Fanny ... -
Treating urinary tract infections in public sector primary healthcare facilities in Cape Town, South Africa: A pharmaceutical perspective
