Chlorine oxidation of VOCs at a semi-rural site in Beijing: significant chlorine liberation from ClNO2 and subsequent gas- and particle-phase Cl–VOC production
(European Geosciences Union (EGU), 2018)
Nitryl chloride (ClNO2) accumulation at night acts
as a significant reservoir for active chlorine and impacts the
following day’s photochemistry when the chlorine atom is
liberated at sunrise. Here, we report simultaneous ...
An electrochemically active green synthesized polycrystalline NiO/MgO catalyst: Use in photo-catalytic applications
(Elsevier, 2018)
For many years, research scientists have aided communities in their tremendous efforts towards environmental remediation. Due to their high physical and chemical stability, metal oxide nanoparticles (NPs) have been used as ...
Spectroscopic and voltammetric analysis of platinum group metals in road dust and roadside soil
(MDPI, 2018)
The emission of toxic compounds by increasing anthropogenic activities affects human
health and the environment. Heavy road traffic and mining activities are the major anthropogenic
activities contributing to the presence ...
A two-decade anthropogenic and biogenic isoprene emissions study in a London urban background and a London urban traffic site
(MDPI, 2018)
A relationship between isoprene and 1,3-butadiene mixing ratios was established to
separate the anthropogenic and biogenic fractions of the measured isoprene in London air in both
urban background (Eltham) and urban ...
Compaction of a zirconium metal–organic framework (UiO-66) for high density hydrogen storage applications
(Royal Society of Chemistry, 2018)
We report a rare case whereby a metal–organic framework (MOF), namely UiO-66, is compacted at high
pressure ( 700 MPa or 100 000 psi) resulting in densification and improved total volumetric hydrogen
storage capacity, ...
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 ...
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 ...
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 ...
