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 ...
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 ...
Treatment of acid mine drainage with coal fly ash in a jet loop reactor pilot plant
(Minerals Engineering, 2020)
A 1500 L batch jet loop reactor pilot plant was designed, constructed, and evaluated for performance in the treatment of acid mine drainage (AMD) using coal fly ash with a view to optimize its operation and generate ...
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. ...
Metal oxide (Co3O4 and Mn3O4) impregnation into S, N-doped graphene for oxygen reduction reaction (ORR)
(MDPI, 2020)
To address aggravating environmental and energy problems, active, efficient, low-cost, and robust electrocatalysts (ECs) are actively pursued as substitutes for the current noble metal ECs. Therefore, in this study, we ...
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 ...
New palladium(II) and platinum(II) complexes based on pyrrole Schiff bases: synthesis, characterization, X-ray structure, and anticancer activity
(American Chemical Society, 2020)
New palladium (Pd)II and platinum (Pt)II complexes (C1−C5) from the Schiff
base ligands, R-(phenyl)methanamine (L1), R-(pyridin-2-yl)methanamine (L2), and R-(furan2-yl)methanamine (L3) (R-(E)-N-((1H-pyrrol-2-yl) methylene)) ...
