High stability asymmetric supercapacitor cell developed with novel microwave-synthesized graphene-stabilized ruthenium antimonide nanomaterial
(Elsevier, 2023-02-06)Ruthenium antimony oxide (RuSbO), and ruthenium antimony oxide graphene (RuSbO-G) nanomaterial was synthesized via the microwave-assisted method for the first time and tested as a possible electrode material for an asymmetric ... -
Integrating RADAR and optical imagery improve the modelling of carbon stocks in a mopane-dominated African savannah dry forest
(Wiley, 2022-12-25)This study examined the integration of two satellite data sets, that is Landsat 7 ETM+ and ALOS PALSAR (Advanced Land Observing Satellite Phased Array type L-band Synthetic Aperture RADAR) in estimating carbon stocks in ... -
Disturbed, diffuse, or just missing? A global study of the H I content of Hickson compact groups
(EDP Sciences, 2023)Context. Hickson compact groups (HCGs) are dense configurations of four to ten galaxies, whose H I morphology appears to follow an evolutionary sequence of three phases, with gas initially confined to galaxies, then ... -
Mesoscale structure of neuston assemblages across the southern Indian Ocean subtropical gyre
(Elsevier, 2022-12-28)Despite concern around plastic pollution in subtropical gyres, our understanding of the biological component of the neustonic layer (upper 20 cm of the ocean) in these areas is poor. Here we investigate the neuston ... -
Establishing provenance from highly impoverished heavy mineral suites: Detrital apatite and zircon geochronology of central North Sea Triassic sandstones
(MDPI, 2022-12-30)A study of Triassic sandstones in the central North Sea, UK, has shown that combined detrital zircon and apatite geochronology and apatite trace element analysis is a powerful tool for reconstructing provenance for ... -
Using multiplex amplicon pcr technology to efficiently and timely generate rift valley fever virus sequence data for genomic surveillance
(MDPI, 2023)Rift Valley fever (RVF) is a febrile vector-borne disease endemic in Africa and continues to spread in new territories. It is a climate-sensitive disease mostly triggered by abnormal rainfall patterns. The disease is ... -
Enzymatic and proteomic exploration into the inhibitory activities of lemongrass and lemon essential oils against botrytis cinerea (causative pathogen of gray mold)
(Front. Microbiol, 2023)Introduction: Essential oils (EOs) have been demonstrated as efficacious against B. cinerea. However, the underpinning enzymatic and proteomic mechanism for these inhibitory effects is not entirely clear. Methods: Thus, ... -
Muscle fiber type and metabolic profiles of four muscles from the African black ostrich
(Meat Science, 2023)Muscle fiber type, fiber cross-sectional area (CSA), enzyme activities (citrate synthase (CS), 3-hydroxyacetyl Co A dehydrogenase (3HAD), lactate dehydrogenase (LDH) and phosphofructokinase (PFK)) and glycogen content were ... -
Evaluation of Terminalia macroptera (Combretaceae) Guill. & Perr stem bark extract incorporated into an emulgel for the potential management of rheumatoid arthritis
(Scientific African, 2023)Background: Rheumatoid Arthritis (RA) is a chronic disease which causes inflammation and damage to the joint. The goals of treatment are to stop inflammation, relieve symptoms, improve physical function and overall well-being. ... -
Proprotein convertase subtilisin/kexin type 9 genetic screening using the vervet (Chlorocebus aethiops) model
(Journal of Medical Primatology, 2022)Background: The proprotein convertase subtilisin/kexin type 9 (PCSK9) gene has come to prominence due to its reported function in the clearance of low-density li-poprotein cholesterol. The vervet monkey (Chlorocebus ... -
Defining regional and local sediment sources in the ancestral Colorado River system: A heavy mineral study of a mixed provenance unit in the Fish creek-vallecito basin, Southern California
(MDPI, 2023)The Colorado River has flowed across the dextral strike-slip plate boundary between the North American and Pacific plates since the latest Miocene or earliest Pliocene. The Fish Creek- Vallecito Basin (FCVB) lies on the ... -
Temporal partitioning of Bullacris unicolor (Orthoptera: Pneumoridae) calling activity to avoid predation
(Taylor and Francis Group, 2023)Ecological interactions, including competition, predation, and environmental conditions, may significantly impact acoustic signal-ling behaviour. Here we characterise nocturnal signalling patterns in the bladder grasshopper ... -
Global simulations of multi-frequency hf signal absorption for direct observation of middle atmosphere temperature and composition
(Wiley, 2023)This paper presents the first numerical study on a new concept for the direct measurement of D-region absorption in the high-frequency (HF) band. Numerical simulations based on the Appleton-Hartree and Garrett equations ... -
Nanostructured europium-doped layered lithium manganese oxide as a prospective cathode material for aqueous lithium-ion battery
(Elsevier, 2023)As the world moves to greener and renewable energy generation technologies, scientific researchers are facing a great challenge of concurrently developing energy storage materials with a low production cost, environmentally ... -
An∼600 pc view of the strongly lensed, massive main-sequence galaxy j0901: A baryon-dominated, thick turbulent rotating disk with a clumpy cold gas ring at z=2.259
(American Astronomical Society, 2023)We present a high-resolution kinematic study of the massive main-sequence star-forming galaxy (SFG) SDSS J090122.37+181432.3 (J0901) at z = 2.259, using ∼0 36 Atacama Large Millimeter/submillimeter Array CO(3–2) and ∼0 ... -
