Investigating the background and local contribution of the oxidants in London and Bangkok
(Royal Society of Chemistry, 2021)
Birth registration marks a child’s right to identity and is the first step to establishing citizenship and access to services. At the population level, birth registration data can inform effective programming and planning. ...
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) = ...
Rare earths’ recovery from phosphogypsum: An overview on direct and indirect leaching techniques
(MDPI, 2021)
The need for rare earth elements (REEs) in high-tech electrical and electronic-based materials is vital. In the global economy, deposits of natural REEs are limited except for countries such as China, which has prompted ...
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 ...
