Enhanced low-humidity performance of proton exchange membrane fuel cell by incorporating phosphoric acid-loaded covalent organic framework in anode catalyst layer
(Elsevier, 2021)
Developing self-humidifying membrane electrode assembly (MEA) is of great significance for the practical use of proton exchange membrane fuel cell (PEMFC). In this work, a phosphoric acid (PA)-loaded Schiff base networks ...
Removal of pharmaceutical residues from water and wastewater using dielectric barrier discharge methods—A review
(MPDI, 2021)
Persistent pharmaceutical pollutants (PPPs) have been identified as potential endocrine disruptors that mimic growth hormones when consumed at nanogram per litre to microgram per litre concentrations. Their occurrence in ...
PM2.5 chemical composition and geographical origin of air masses in Cape Town, South Africa
(Springer Science and Business Media Deutschland GmbH, 2021)
PM2.5 in the indoor and outdoor environment has been linked in epidemiology studies to the symptoms, hospital admissions and development of numerous health outcomes including death. The study was conducted during April ...
Co-pelletization of a zirconium-based metal-organic framework (UiO-66) with polymer nanofibers for improved useable capacity in hydrogen storage
(Elsevier, 2021)
We report on a concept of co-pelletization using mechanically robust hydroxylated UiO-66 to develop a metal-organic framework (MOF) monolith that contains 5 wt% electrospun polymer nanofibers, and consists of an architecture ...
Synthesis, characterization and anticancer activity of new 2-acetyl-5-methyl thiophene and cinnamaldehyde thiosemicarbazones and their palladium(II) complexes
(Elsevier S.A., 2021)
New thiosemicarbazone (TSC) ligands, AMT-C[dbnd]N-TSCH (L1), AMT-C[dbnd]N-TSC(CH3) (L2), CIN-C[dbnd]N-TSCH (L3) and CIN-C[dbnd]N-TSC(CH3) (L4) (AMT = 2-acetyl-5-methylthiophene, TSCH = thiosemicarbazide, TSC(CH3) = ...
The behaviour of rare earth elements from South African coal fly ash during enrichment processes: wet, magnetic separation and zeolitisation
(MDPI, 2021)
are earth elements (REEs) are essential raw materials in a variety of industries including clean energy technologies such as electric vehicles and wind turbines. This places an ever-increasing demand on global rare earth ...
Solid-phase synthesis of arylidene and alkylidene malonates, as versatile intermediates, catalyzed using mesoporous poly-melamine–formaldehyde as a nitrogen-rich porous organic polymer (POP)
(Springer, 2021-09)
An efficient solid/slurry-state synthesis of arylidene and alkylidene malonates as versatile intermediates is developed in the presence of mesoporous poly-melamine–formaldehyde. The condensation reaction was conducted ...
Fabrication of silver‑coated PET track‑etched membrane as SERS platform for detection of acetaminophen
(Springer, 2021-09)
In this study, silver nanoparticles (AgNPs) were immobilized on the surface of polyethylene terephthalate (PET) membrane
using diethylenetriamine (DETA) as a chemical linker. The molecule of DETA was attached to the surface ...
The low-redshift circumgalactic medium in SIMBA
(Oxford University Press, 2021-08)
We examine the properties of the low-redshift circumgalactic medium (CGM) around star-forming and quenched galaxies in
the SIMBA cosmological hydrodynamic simulations, focusing on comparing H I and metal line absorption ...
1D NiHPO4 nanotubes prepared using dissolution equilibrium as bifunctional electrocatalyst for high-efficiency water splitting
(Journal of Power Sources, 2021)
In this work, one-dimensional NiHPO4 nanotubes are successfully fabricated on nickel foam by hydrothermal reaction, in which a dissolution equilibrium between phosphates is controlled by tuning the proportion of the mixed ...
