The extent of microplastics in African freshwater systems remains less investigated. In Sudan, there is no single study reporting microplastics in water bodies. This scoping study aimed to investigate the presence and ...
Mining wastewater can have adverse effects on the ecosystem; thus, treatment before discharging into the environment is of utmost importance. This manuscript reports on the effect of mining wastewater on the environment. ...
The in-vitro synthesis of bio-compounds via fermentation is a promising route for bioactive molecules intended for disease control and management. Therefore, this study evaluated the effect of fermentation on the antioxidants, ...
Before the introduction of Bactrocera dorsalis (Hendel) to sub-Saharan Africa, Ceratitis cosyra (Walker) was economically the most important pest in mango farming. Its native natural enemy, the solitary parasitoid Psyttalia ...
The aim of this study was to examine the physical characteristics and chemical composition of microplastics in sediments of the Vaal River, South Africa. Microplastics were detected in all samples, with abundance ranging ...
The mining and processing of some minerals and coal result in the production of acid mine drainage (AMD) which contains elevated levels of sulfate and metals, which tend to pose serious environmental issues. There are ...

This manuscript reports the investigation of the polymorphic behaviour of fipronil using a systematic comparison of the thermochemical and structural properties of different crystal forms obtained in this study as well as ...
In the absence of work, the exchange of heat of a sample of matter corresponds to the
change of its internal energy, given by the kinetic energy of random translational motion of all its
constituent atoms or molecules ...
Microplastics research in South Africa has focused on marine and coastal areas, with limited studies reporting microplastics in freshwaters. To address this gap, we conducted this study to investigate the presence, abundance, ...

A new family of single-pocket metal complexes bearing O,N,O-tridentate and O,N-bidentate chelating members {Cu, 1b (P21/n); Ni, 1c (C2/c); Mn, 1d (I2/a); Cu, 2b; and Ni, 2c (both P21/c)}, starting from synthesized and fully ...
Coumarin synthase (COSY) is the key enzyme involved in the coumarin biosynthesis. Although it has been identified firstly in Arabidopisis thaliana, there is little known about the COSY gene function in Clematis terniflora ...

The negative health and socio-economic impacts of emissions associated with domestic fuel burning are widely recognized. Although
there has been much progress in the provision of electricity to households in South Africa, ...
Proximate analyses and decomposition profiles of solid fuels commonly used in Kenya were studied to determine their
relative suitability for use as a clean and efficient source of energy in households. The moisture, ...
Electrospun multicomposite nanofibers synthesized from extracts of Moringa oleifera (M. oleifera) seed biomass blended
with metal oxide nanoparticles (MONPs) and polyacrylonitrile (PAN) were investigated as potential ...
The kinetics of methanol synthesis remains debatable for various reasons, such as the lack
of scientifically conclusive agreement about reaction mechanisms. The focus of this paper is on the
evaluation of the intrinsic ...
