Biosynthesis and photocatalytic properties of SnO2 nanoparticles prepared using aqueous extract of cauliflower
(Springer, 2017)This work reports the biosynthesis of Sn(OH)2 using aqueous extract of fresh cauliflower (Brassica oleracea L. var. botrytis), and the subsequent preparation of SnO2 nanoparticles at two different annealing temperatures ... -
Biosynthesis, characterization, and antimicrobial effect of silver nanoparticles obtained using Lavandula × intermedia
(SpringerSpringer, 2017)The use..... of aqueous leaf extract of Lavandula × intermedia for biosynthesis of silver nanoparticles (AgNPs) is presented. The plant extract was obtained by boiling dried leaves and using the obtained filtrate for the ... -
Biosynthesis, electrochemical, antimicrobial and antioxidant studies of silver nanoparticles mediated by talinum triangulare aqueous leaf extract
(Springer, 2017)Silver nanoparticles (AgNPs) were synthesized using leaf extract of Talinum triangulare (TT). The nanoparticles were characterised using Infra-red spectroscopy, UV-vis spectroscopy, X-ray diffraction, scanning electron ... -
Biotechnology in Agriculture: risks and opportunities for the rural poor in Semi-Arid-Tropics
(Kamla-Raj, 2016)In spite of the fact that neediness and nourishment frailty give off an impression of being developed in urban areas as urbanization continues a pace in a large portion of the developing nations, almost seventy percent of ... -
Biotransformation profiles from a cohort of chronic fatigue women in response to a hepatic detoxification challenge
(Public Library of Science, 2019)Chronic fatigue, in its various manifestations, frequently co-occur with pain, sleep disturbances and depression and is a non-communicable condition which is rapidly becoming endemic worldwide. However, it is handicapped ... -
Biotransport of metallic trace elements from marine to terrestrial ecosystems by seabirds
(Wiley, 2019)Physical systems, such as currents and winds, have traditionally been considered responsible for transporting contaminants. Although evidence is mounting that animals play a role in this process through their movements, ... -
The bipyridine adducts of N-phenyldithiocarbamato complexes of Zn(II) and Cd(II); synthesis, spectral, thermal decomposition studies and use as precursors for ZnS and CdS nanoparticles
(Elsevier, 2015)Bipyridine adducts of N-phenyldithiocarbamato complexes, [ML12L2] (M = Cd(II), Zn(II); L1 = N-phenyldithiocarbamate, L2 = 2,2′ bipyridine), have been synthesized and characterised. The decomposition of these complexes to ... -
Bird species richness and densities in relation to sulphur dioxide gradients and environmental variables
(Taylor & Francis, 2017)The expansion of coal-fired power stations in South Africa has resulted in growing environmental concerns as they are the largest emitters of sulphur dioxide (SO2). Sulphur dioxide emissions from power plants pose a potential ... -
Birds associated with a tailings storage facility and surrounding areas from a South African

Birds mediate a fungus-mite mutualism
(Springer, 2018)Mutualisms between ophiostomatoid fungi and arthropods have been well documented. These fungi commonly aid arthropod nutrition and, in turn, are transported to new niches by these arthropods. The inflorescences of Protea ... -
Bis diallyl dithiocarbamate Pt(II) complex: synthesis, characterization, thermal decomposition studies, and experimental and theoretical studies on its crystal structure
(Taylor & Francis, 2015)Platinum dithiocarbamate (DTC) complex has been synthesized from the ligand diallyl DTC, and its structure was established from elemental analysis, IR, NMR, and single-crystal X-ray analyses to be Pt[S2CN(C3H5)2]2. The ... -
A bis(pyridyl)-N-alkylamine/Cu(I) catalyst system for aerobic alcohol oxidation
(RSC, 2017)Herein a bis(pyridyl)-N-alkylamine/CuI/TEMPO/NMI catalyst system is reported for aerobic oxidation of a variety of primary alcohols to the corresponding aldehydes using readily available reagents, at room temperature and ... -
