Quantification of radicals generated in a sonicator
(Iranian Chemical Society, 2016)
The hydroxyl radical (OH•) is a powerful oxidant produced as a consequence of cavitation in water. It can react nonspecifically in
breaking down persistent organic pollutants in water into their mineral form. It can also ...
Treatment of persistent organic pollutants in wastewater using hydrodynamic cavitation in synergy with advanced oxidation process
(Springer, 2017)
Persistent organic pollutants (POPs) are very tenacious wastewater contaminants. The consequences of their existence have been acknowledged for negatively affecting the ecosystem with specific impact upon endocrine disruption ...
Polysaccharides from the South African medicinal plant Artemisia afra: Structure and activity studies
(Elsevier, 2018)
Artemisia afra (Jacq. Ex. Willd), is an indigenous plant in South Africa and other parts of the African continent, where it is used as traditional medicine mostly for respiratory conditions. The objective of this study was ...
The effect of a warm electron beam on slow electron-acoustic solitons
(AIP Publishing, 2018)
The effects of the inclusion of finite drift speed of a warm electron component on the existence of arbitrary amplitude slow electron-acoustic solitons are investigated in a model with ions and cool, warm, and hot electrons. ...
Effect of growth temperature on the structural, optical and luminescence properties of cadmium telluride nanoparticles
(Springer, 2018)
Cadmium telluride (CdTe) has been successfully prepared by a simple wet chemical process at different reaction temperatures. Temperature is one parameter that thermodynamically plays an important role in controlling the ...
The effect of PtRuIr nanoparticle crystallinity in electrocatalytic methanol oxidation
(MDPI, 2013)
Two structural forms of a ternary alloy PtRuIr/C catalyst, one amorphous and one highly crystalline, were synthesized and compared to determine the effect of their respective structures on their activity and stability as ...
Actuation behaviour of a derivatized pyrrole accordion type polymer
(ESG, 2014)
A monomer (Phenazine-2,3-diimino(pyrrole-2-yl)–PDP) derived from the condensation reaction between 2,3-diaminophenazine and a pyrrole derivative has been synthesized as a hinge molecule in the design of a zig-zag polymer. ...
Voltammetric and spectroscopic determination of rare earth elements in fresh and surface water samples
(MDPI, 2018)
The increasing demand for rare earth elements in green technology, electronic components,
petroleum refining, and agricultural activities has resulted in their scattering and accumulation in the
environment. This study ...
Sensitive electrochemical determination of ethambutol in pharmaceutical formulation and human urine at nickel nanoparticles/electrochemically reduced graphene oxide modified electrode
(Chemical Society of Ethiopia, 2019)
This paper describes the application of nickel nanoparticles decorated electrochemically reduced
graphene oxide modified glassy carbon electrode (NiNPs/ERGO/GCE) for the determination of ethambutol
(ETB), an anti-Mycobacterium ...
Electrochemical determination of phenothrin in fruit juices at graphene oxide-polypyrrole modified glassy carbon electrode
(Elsevier, 2018)
An electrochemical sensor was developed based on graphen oxide-polypyrrole modified glassy carbon electrode
(GO/PPy/GCE) for sensitive determination of phenothrin in fruit samples. GO/PPy/GCE was characterized by
scanning ...
