The microspherical catalysts also proved to be recyclable with no drop in activity being observed after three successive reactions. The vanadium functionalized fibers were applied in a pseudo continuous flow set-up. Factors influencing the overall conversion and product selectivity, including flow rate and catalyst quantity, were investigated. At flow rates of 1–4 mL h−1 near quantitative conversion was maintained over an extended period. Keeping the mass of catalyst constant (0.025 g) and varying the flow rate from 1–6 mL h−1 resulted in a shift in the formation of the oxidation product methyl phenyl sulfone from 60.1 to 18.6%.]]> Wed 10 Apr 2024 14:17:42 SAST ]]> A highly selective and sensitive pyridylazo-2-naphthol-poly (acrylic acid) functionalized electrospun nanofiber fluorescence “turn-off” chemosensory system for Ni 2+ https://vital.seals.ac.za/vital/access/manager/Repository/vital:51428 Wed 05 Apr 2023 08:50:33 SAST ]]> Single walled carbon nanotubes functionalized with nickel phthalocyanines https://vital.seals.ac.za/vital/access/manager/Repository/vital:51410 Tue 24 May 2022 23:20:15 SAST ]]> Electrocatalytic behavior of cobalt phthalocyanine complexes immobilized on glassy carbon electrode towards the reduction of dicrotophos pesticide https://vital.seals.ac.za/vital/access/manager/Repository/vital:51409 Tue 24 May 2022 23:11:37 SAST ]]> Schottky barrier diode parameters of Ag/MgPc/p-Si structure https://vital.seals.ac.za/vital/access/manager/Repository/vital:51408 Tue 24 May 2022 22:59:57 SAST ]]> In vitro photodynamic effect of aluminum tetrasulfophthalocyanines on melanoma skin cancer and healthy normal skin cells https://vital.seals.ac.za/vital/access/manager/Repository/vital:51403 Tue 24 May 2022 22:06:43 SAST ]]> Synthesis and physicochemical behaviour of aluminium trikis and tetrakis (diaquaplatinum) octacarboxyphthalocynine https://vital.seals.ac.za/vital/access/manager/Repository/vital:51068 Tue 24 May 2022 15:40:41 SAST ]]> Linking poverty, HIV/AIDS and climate change to human and ecosystem vulnerability in southern Africa: Consequences for livelihoods and sustainable ecosystem management https://vital.seals.ac.za/vital/access/manager/Repository/vital:43697 Tue 24 Aug 2021 16:29:46 SAST ]]> A comparative study on the sensitive detection of hydroxyl radical using thiol-capped CdTe and CdTe/ZnS quantum dots https://vital.seals.ac.za/vital/access/manager/Repository/vital:51077 MPA-CdTe@ZnS > TGA-CdTe > MPA-CdTe QDs. Under the optimum conditions, a limit of detection as low as 8.5 × 10-8 M was obtained using GSH-CdTe@ZnS. The effects of foreign reactive oxygen species and the Fenton reactants and products as possible interferences on the proposed probe were negligible for CdTe@ZnS QDs.
