According to the trend observed, the H2TPrOPhOPc was an excellent nonlinear optical limiter when compared to the CoTPrOPhOPc and MnTPrOPhOPc. All the investigated complexes exhibited optical limiting properties comparable to the phthalocyanine complexes reported in the literature. The MTPrOPhOPc complexes were further studied for their electrocatalytic and electroanalytical properties towards the detection of hydrogen peroxide. For the electrocatalytic studies, the synthesized complexes were immobilized onto gold electrode surfaces pre-functionalized with phenylazide (Au-PAz) monolayer. Copper (I) catalyzed alkynyl-azide cycloaddition reaction was used to covalently immobilize the MTPrOPhOPcs onto the gold electrode surfaces to form Au-PAz-MTPrOPhOPc. The MTPrOPhOPcs modified gold surfaces (Au-PAz-MTPrOPhOPc) exhibited good reproducibility and stability in various electrolyte conditions. Electrochemical and surface characterisation of the functionalised gold electrode surfaces confirmed the presence of the MTPrOPhOPcs and their electroanalysis was excellent towards electrocatalytic reduction of H2O2, with the limit of detection (LoD) and limit of quantification (LoQ) in the ^M range. The electrocatalytic reduction peaks for H2O2 were observed at -0.37 V for Au-PAz-MnTPrOPhOPc and -0.31 V for Au-PAz-CoTPrOPhOPc when Ag|AgCl pseudo-reference electrode was used. The Au-PAz-MnTPrOPhOPc and Au- PAz-CoTPrOPhOPc gold electrode surfaces showed good sensitivity and reproducibility towards the electrocatalytic reduction of hydrogen peroxide in pH 7.4 phosphate buffer solution.]]> Thu 20 Apr 2023 09:37:14 SAST ]]> A critique of language policy and implementation strategies used in selected institutions of higher learning in South Africa Thu 18 May 2023 15:27:00 SAST ]]> A micro-ethnography: exploring relations between Somali and South African traders in Clarehill, Cape Town Thu 18 May 2023 14:24:18 SAST ]]> Woody plant encroachment in arid and mesic South African savanna-grasslands: same picture, different story?

This research was carried out in a randomized field trial. Finally, to gain a broader understanding of the effects of contrasting soil management systems on soil microbiology under a greater variety of environmental conditions, arbuscular mycorrhizal (AM) fungal dynamics were explored in a survey of commercial apple orchards. These orchards were selected to span the range of environmental conditions that occur in the apple production areas of the Western Cape. Orchard soils under ORG management promoted richer microbial ecosystems, and appeared to be better able to sustain community metabolic diversity and, by inference, the functions mediated by soil microbial communities, than those under CON management. This implies that ORG approaches possibly afford a better option to sustain critical ecosystem functions than CON management. This possibly explains why use of straw mulches and compost in accordance with ORG practices, compared with CON practices, promoted β-glucosidase, acid phosphatase and urease activities rather than affecting the abundance of the micro-organisms that produce these enzymes. Enzyme activities in the 0–30 cm soil intervals were also more effectively promoted by ORG than CON practices, although no differences were observed at lower depth intervals. ORG practices promoted functional AM associations more effectively than CON practices, but the abundance of glomalin, a beneficial by-product of AM fungi, was unaffected. The greater enzyme activities and higher root colonisation levels in the ORG treatments probably contributed to improved nutritional effects that caused greater vegetative growth, but lower yields, in the ORG treatments. Yield suppression was conceivably due to excessive vegetative growth induced by oversupply of compost and the mineral nutrients contained therein. The survey of Western Cape apple orchards suggested that neither glomalin nor root colonisation bore any specific relationship to production area, cultivation practice, scion x rootstock combination, or, in the case of root colonisation, with any chemical parameters. However, the effect of season on glomalin was conclusively shown, being higher in summer than in spring, as was the lack of any effect of year on glomalin and root colonisation. Collectively, these results showed that ORG soil management promote soil microbiology, soil nutrient status, and apple tree performance compared to CON management.]]> Mon 24 Apr 2023 10:18:55 SAST ]]> Comparative fish ecology in three periodically connected rivers in the upper Zambezi and Okavango ecoregions Mon 24 Apr 2023 08:33:54 SAST ]]> A comparison of the legal environmental sustainability requirements of those engaging in the mining cycle, with actual practice in the Carolina X11B quaternary catchment, Mpumalanga, South Africa Mon 22 May 2023 15:47:55 SAST ]]> Performance evaluation and cost analysis of subsurface flow constructed wetlands designed for ammonium-nitrogen removal Mon 22 May 2023 14:58:54 SAST ]]> Researching the development of a programme that merges mathematics and music in Grade R Mon 22 May 2023 08:40:56 SAST ]]> Informal learning in local farming practices by rural women in the Lake Chilwa Basin, Malawi: towards coping and adaptation to climate variability and climate change Mon 17 Apr 2023 11:28:01 SAST ]]> An investigation into the bacterial biosynthetic origins of bioactive natural products isolated from South African latrunculid sponges Mon 05 Jun 2023 15:41:21 SAST ]]> A review of the implementation of the CAPS Life Skills curriculum training, as a recontextualising process, in engaging teachers in environmental education in two districts of the Eastern Cape Province Mon 05 Jun 2023 15:06:28 SAST ]]> The impact of leadership on job satisfaction at a specific bank in the Eastern Cape Mon 05 Jun 2023 13:28:12 SAST ]]> An investigation of the response of entities in the South African JSE ICT sector in 2005 to environmental sustainability reporting Mon 05 Jun 2023 12:39:19 SAST ]]> The experiences of recently diagnosed HIV-positive individuals, as shared on an online forum Mon 05 Jun 2023 09:23:18 SAST ]]> HIV-related stigma amongst service staff in Grahamstown: a comparison of Hi-Tec security guards and Rhodes catering in the Eastern Cape Mon 05 Jun 2023 08:49:17 SAST ]]> Barriers and drivers to the implementation of renewable energy technologies in South Africa’s aquaculture industry Fri 26 May 2023 11:09:43 SAST ]]> Indigenous and traditional musics in the school classroom : a re-evaluation of the South African Indigenous African Music (IAM) curriculum Fri 19 May 2023 15:42:21 SAST ]]> The changing face of Rhodes University: exploring aspects of visuality, sexuality and protest between the apartheid and postapartheid periods Fri 19 May 2023 12:39:03 SAST ]]> “Don’t forget to be awesome”: the role of social learning as a component of belonging in virtual communities: a case study of the Youtube fan community “Nerdfighteria” Fri 19 May 2023 11:29:02 SAST ]]> Quantification of pre-competitive sleep/wake behaviour in a sample of South African cyclists Fri 19 May 2023 10:05:04 SAST ]]> Bayesian hierarchical modelling with application in spatial epidemiology Fri 19 May 2023 09:37:03 SAST ]]> Periglacial landforms of the Ahlmannryggen and Jutulsessen areas of western Dronning Maud land, Antarctica Fri 02 Jun 2023 11:43:09 SAST ]]> An exploratory study of students’ expectations and perceptions of service quality in a South African higher education institution Fri 02 Jun 2023 10:12:34 SAST ]]> Practical application of distributed ledger technology in support of digital evidence integrity verification processes Fri 02 Jun 2023 09:09:15 SAST ]]>
