Novel heterojunction superstrate Cu2ZnInS4−x (CZIS) thin film kesterite solar cell with vertical arrays of hexagonal ZnO nanorods window layer
(Elsevier, 2022-11-24)Quaternary Cu2ZnInS4−x (CZIS) thin films have been prepared by a facile and cheap sol-gel spin coating technique. Low-temperature solution-based methods were used to fabricate a heterojunction solar cell in the superstrate ... -
Supplementation of recombinant cellulases with LPMOs and CDHs improves consolidated bioprocessing of cellulose
(Elsevier, 2023)The increased demand for energy has sparked a global search for renewable energy sources that could partly replace fossil fuel resources and help mitigate climate change. Cellulosic biomass is an ideal feedstock for renewable ... -
Discovery of a filamentary synchrotron structure connected to the coherent magnetic field in the outer galaxy
(The Astrophysical Journal, 2023)Using data from the Galactic Arecibo L-band Feed Array Continuum Transit Survey, we report the discovery of two previously unidentified, very compressed, thin, and straight polarized filaments approximately centered at ... -
The physical nature of circumgalactic medium absorbers in SIMBA
(Oxford University Press, 2023)We study the nature of the low-redshift circumgalactic medium (CGM) in the SIMBA cosmological simulations as traced by ultraviolet absorption lines around galaxies in bins of stellar mass (M > 1010M) for star-forming, ... -
In a rough spot: Declines in Arthroleptella rugosa calling densities are explained by invasive pine trees
(Wiley, 2023)Basing conservation interventions on evidence is important for justifying their associated cost and gauging their effectiveness. For amphibians, the number of studies available to support conservation ... -
Characterization of blocks within a near seafloor Neogene MTC, Orange Basin: Constraints from a high-resolution 3D seismic data
(Elsevier, 2023)Submarine mass wasting processes in deepwater settings can incorporate large blocks, which may play a key role in deepwater geological processes and geohazard assessment. However, there is a limited understanding of ... -
Comparative proteomics analysis between maize and sorghum uncovers important proteins and metabolic pathways mediating drought tolerance
(MDPI, 2023)Drought severely affects crop yield and yield stability. Maize and sorghum are major crops in Africa and globally, and both are negatively impacted by drought. However, sorghum has a better ability to withstand drought ... -
Petroleum source rock potential evaluation: A case study of block 11a, Pletmos sub‑basin, offshore South Africa
(Springer, 2023)Among the several existing geochemical methods in hydrocarbon exploration, the technique linking total organic carbon content (TOC) and Rock–Eval pyrolysis is most widely used, largely as a result of its capacity to rapidly ... -
Antimycobacterial activity and molecular docking of methanolic extracts and compounds of marine fungi from Saldanha and False Bays, South Africa
(Elsevier, 2022)The number and diversity of drugs in the tuberculosis (TB) drug development process has increased over the years, yet the attrition rate remains very high, signaling the need for continued research in drug discovery. In ... -
Development of Unsupported Ru and Ni Based Oxides with Enhanced Performance for the Oxygen Evolution Reaction in Acidic Media
(Springer, 2023)The high cost of catalyst materials suitable for the oxygen evolution reaction (OER) in polymer electrolyte membrane water electrolyzers (PEMWE) is still a major hurdle that needs overcoming before commercial PEMWE can ... -
Strategies for malaria vaccination during the Covid-19 pandemic in African countries
(World Health Organization, 2022)Since October 2021, the World Health Organization (WHO) recommends the use of RTS,S/AS01 (RTS,S) malaria vaccine for children in areas of moderate to high transmission of Plasmodium falciparum in Africa.1 The vaccine ... -
Face-to-face versus online-based lectures: A COVID-19 induced study on assessments
(Frontiers in Education, 2022)The students were found to be resilient in adapting to things and learning, online presentations, and computer-based assessments. No gender-based difference or advantage to adjusting to newly introduced blended learning ... -
ALMA lensing cluster survey: Hubble space telescope and spitzer photometry of 33 lensed fields built with CHArGE
(IOP Publishing, 2022)We present a set of multiwavelength mosaics and photometric catalogs in the Atacama Large Millimeter/submillimeter Array (ALMA) lensing cluster survey fields. The catalogs were built by the reprocessing of archival data ... -
Proteomics analysis of the p.G849D variant in neurexin 2 alpha may reveal insight into Parkinson’s disease pathobiology
(Frontiers, 2022)Parkinson’s disease (PD), the fastest-growing neurological disorder globally, has a complex etiology. A previous study by our group identified the p.G849D variant in neurexin 2 (NRXN2), encoding the synaptic protein, ... -
Attenuation of hyperglycemia-associated dyslipidemic, oxidative, cognitive, and inflammatory crises via modulation of neuronal ChEs/NF-κB/COX-2/NOx, and hepatorenal functional deficits by the Tridax procumbens extract
(Elsevier, 2023)Tridax procumbens (cotton buttons) is a flowering plant with a medicinal reputation for treating infections, wounds, diabetes, and liver and kidney diseases. The present research was conducted to evaluate the possible ... -
