The incorporation of the MWCNTs on the surface of the TiO2 film (MOCPc–MWCNT systems) gave higher photocurrent density than the bare MOCPc complexes. Also, from the EIS results, the MOCPc–MWCNT hybrids gave faster charge transport kinetics (approximately three times faster) compared to the bare MOCPc complexes. The electron lifetime was slightly longer (ca. 6 ms) at the ZnOCPc systems than at the (OH)2SiOCPc system (ca. 4 ms) meaning that the presence of the MWCNTs on the surface of the TiO2 film did not show any significant improvement on preventing charge recombination process.]]> Tue 18 Jul 2023 21:24:00 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:68212 Tue 10 Oct 2023 09:30:18 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:38436 Tue 09 Aug 2022 05:28:24 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:35644 Tue 09 Aug 2022 05:24:53 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:45396 Tue 07 Dec 2021 11:39:14 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:64342 Tue 06 Jun 2023 09:16:06 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:41455 Tue 05 Mar 2024 12:00:24 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:70204 Thu 30 Nov 2023 14:00:46 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:65318 Thu 29 Jun 2023 11:26:31 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:44951 Thu 28 Oct 2021 22:28:15 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:44950 Thu 28 Oct 2021 22:21:03 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:44945 Thu 28 Oct 2021 12:28:03 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:38345 Thu 26 Aug 2021 15:12:40 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:63662 Thu 20 Apr 2023 11:55:50 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:69142 Thu 19 Oct 2023 11:06:37 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:35748 Thu 15 Jul 2021 21:16:34 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:26580 99 % in selectively extracting the metalloporphyrins. The impact of the template on the affinity of recognition for NTPP was evaluated. The results showed that the NTPP adsorption capacity increased as the molar ratio of NTPP to styrene was increased from 1:1 to 3:1. The optimal ratio of template to functional monomer which yielded the best specific affinity and highest recovery (99.9 %) was 3:1. The effects of trifluoroacetic acid (TFA), dichloromethane (DCM), dimethyl sulphoxide (DMSO), pentane (PEN) on electro-spinnability of the polymer solutions and the morphological appearance of the nanofibers were investigated. The imprinted nanofibers exhibited the same selectivity specialism for both NTPP and VTPP. A remarkable stability in relation to reusability was observed when imprinted nanofibers were used, as they could be reused nine times without incurring any significant loss in removal efficiency. The results were validated by analysing a certified reference material. The imprinted sorbents were therefore found to be selective sorbents that are well suited for handling trace metals in organic media.]]> Thu 13 May 2021 09:54:20 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:28540 Thu 13 May 2021 07:35:41 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:29380 20% habitat loss due to invasion). Upstream invasion by centrarchids isolated and fragmented P. afer populations into headwater refugia, while top down invasion by salmonids excluded B. trevelyani from invaded, more pristine stream reaches, by forcing the species into degraded unsuitable lower stream reaches. Predation also disrupted population processes such as adult dispersal for P. afer, and centrarchid-invaded zones acted as demographic sinks, where adults dispersing through invaded reaches were rapidly depleted. While the Mandela lineage of P. afer exhibited little within or between drainage genetic structuring, B. trevelyani was >4% divergent between drainages, and up to 2% divergent between streams within the Keiskamma River system (Chapter 7). The distribution of genetic diversity for B. trevelyani also indicated that the loss of diversity was imminent without immediate conservation interventions. This thesis has provided conclusive evidence that native fishes are vulnerable to invasion and that non-native predatory fishes have significant impacts on native fishes in Eastern Cape headwater streams. If management and conservation measures are implemented, the unwanted introduction and spread of non-native fishes may be restricted, allowing native fishes opportunities for recovery.]]> Thu 13 May 2021 07:28:56 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:4700 Thu 13 May 2021 07:28:05 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:38357 Thu 13 May 2021 06:42:08 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:29149 Thu 13 May 2021 06:36:11 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:7883 Thu 13 May 2021 06:15:41 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:36228 Thu 13 May 2021 06:11:06 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:38246 Thu 13 May 2021 05:41:00 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:38001 Thu 13 May 2021 04:38:33 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:26567 Thu 13 May 2021 04:09:15 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:35728 Thu 13 May 2021 04:06:12 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:27824 Thu 13 May 2021 03:48:30 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:38306 Thu 13 May 2021 02:59:32 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:35850 Thu 13 May 2021 02:33:37 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:37698 Thu 13 May 2021 02:12:22 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:35619 Thu 13 May 2021 01:51:44 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:26597 Thu 13 May 2021 01:03:47 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:38017 Thu 13 May 2021 00:46:23 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:26590 Thu 13 May 2021 00:39:44 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:43884 Thu 13 Apr 2023 18:40:54 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:44580 Thu 11 Aug 2022 12:23:18 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:38245 Thu 11 Aug 2022 06:57:45 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:35499 Thu 11 Aug 2022 06:39:57 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:43116 Thu 07 Mar 2024 14:50:40 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:57216 Thu 06 Jul 2023 06:41:57 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:68625 Thu 05 Oct 2023 09:37:09 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:68624 Thu 05 Oct 2023 09:32:46 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:57720 Sun 23 Oct 2022 22:19:28 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:30641 Sat 09 Sep 2023 09:46:29 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:28017 Sat 04 Dec 2021 12:35:03 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:43670 Mon 30 Aug 2021 15:06:02 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:29194 Mon 30 Aug 2021 14:17:09 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:29197 Mon 30 Aug 2021 14:17:03 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:45401 Mon 29 Nov 2021 11:55:00 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:43181 Mon 14 Jun 2021 14:44:43 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:38346 Mon 08 Aug 2022 09:25:11 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:43678 Mon 05 Jul 2021 14:01:35 SAST ]]>
