The effectiveness of the treatment appeared to be attenuated by the aggregation of Pcs under aqueous conditions. Interestingly, even those cells that were not immediately killed by the photoactivated photosensitizer seemed to be affected by the Pc photodynamic activity, as a single PDT induced long-lasting effects on cell survival. Even 4 days after PDT, the number of surviving cells did not re-increase or still dropped, as compared to control cells. The underlying mechanism of this observation has to be deciphered in future investigations.]]> Tue 07 May 2024 15:55:24 SAST ]]> Steam activation, characterisation and adsorption studies of activated carbon from maize tassels. https://vital.seals.ac.za/vital/access/manager/Repository/vital:35507 Tue 07 May 2024 15:54:59 SAST ]]> Interactive efficacies of Elephantorrhiza elephantina and Pentanisia prunelloides extracts and isolated compounds against gastrointestinal bacteria https://vital.seals.ac.za/vital/access/manager/Repository/vital:35552 Tue 07 May 2024 15:54:35 SAST ]]> Cytotoxicity, phytochemical analysis and antioxidant activity of crude extracts from Rhizomes of Elephantorrhiza Elephantina and Pentanisia Prunelloides https://vital.seals.ac.za/vital/access/manager/Repository/vital:35728 Tue 07 May 2024 15:54:08 SAST ]]> Comparison between base metals and platinum group metals in nitrogen, M codoped TiO 2 (M= Fe, Cu, Pd, Os) for photocatalytic removal of an organic dye in water https://vital.seals.ac.za/vital/access/manager/Repository/vital:35734 Tue 07 May 2024 15:53:45 SAST ]]> Activated carbon from lignocellulosic waste residues: effect of activating agent on porosity characteristics and use as adsorbents for organic species https://vital.seals.ac.za/vital/access/manager/Repository/vital:35748 Tue 07 May 2024 15:53:28 SAST ]]>
