Catalytic dehydrogenation of the liquid organic hydrogen carrier octahydroindole on Pt (111) surface: ab initio insights from density functional theory calculations
(Elsevier, 2019)Ab initio calculations based on dispersion-corrected density functional theory were used to gain insight into the adsorption properties of reactants and products involved in the catalytic dehydrogenation of octahydroindole ... -
Catalytic dehydrogenation onset of liquid organic hydrogen carrier, perhydro-dibenzyltoluene: the effect of Pd and Pt subsurface configurations
(Elsevier, 2019)Perhydro-dibenzyltoluene (H18-DBT) is the hydrogen-rich form of the liquid organic hydrogen carrier (LOHC), dibenzyltoluene. The reversible catalytic hydrogenation and dehydrogenation of LOHCs has made them highly favored ... -
The catalytic effect of Benfield waste salt on CO2 gasification of a typical South African Highveld coal
(Springer, 2019)The possible catalytic effect of a 5% loading by mass of crystallized salt from spent Benfield solution (SBFS) was investigated and compared with the catalytic influence of a 5 mass% loading of K2CO3 on the char–CO2 ... -

Catalytic oxidation of alcohols with novel non-heme N4-tetradentate manganese(II) complexes
(RSC, 2018)We report the preparation and characterisation of a series of novel non-heme N4-tetradentate Mn(OTf)2 complexes of the type, [(L)MnOTf2], where L = R,R and S,S enantiomers of BPMCN, its 6-methyl and 6-bromo derivatives as ... -
Catalytic reduction of 4-nitrophenol using synthesized and characterized CoS@MorphcdtH/CoS@4-MPipzcdtH nanoparticles
(JCCS, 2023)CoS@MorphcdtH NPs and CoS@4-MPipzcdtH NPs were synthesized by precip itation method involving three mechanisms: inclusion, occlusion, and adsorp tion. The synthesized NPs were characterized with the help of UV-Vis spectroscopy, ... -
Category-based phoneme-to-grapheme transliteration
(International Speech Communication Association ( ISCA ), 2013)Grapheme-based speech recognition systems are faster to develop but typically do not reach the same level of performance as phoneme-based systems. In this paper we introduce a technique for improving the performance of ... -
Cathodic protection system design framework
(IEEE, 2019)The aim of this article is to establish a cathodic protection (CP) system design framework for the petrochemical industry in South Africa. The CP system design framework is destined to be used as a guideline when designing ... -
The causes of conflict in public and private sector organizations in South Africa
(University of Primorska Faculty of Management, 2008)The uncertainty that accompanies organizational change heightens prospects for intra organizational conflict. Notwithstanding this, the knowledge base on the sources (or causes) of organizational conflict is underdeveloped ... -
Causes of stress in public schools and its Impact on work performance of educators
(Kamla-Raj Enterprises, 2013)This article reports on educator stress in public schools. In doing so, the article sets the objectives of identifying the causes of stress in public schools of educators in KwaZulu-Natal. The data were collected by means ... -
Caveat magister! Die uitsetting van kosgangers uit koshuise van openbare skole weens onbetaalde koshuisgeld
(LitNet, 2017)Verskeie openbare skole dui in briewe, op webtuistes en in aansoekvorms aan dat 'n kosganger uit die skool se koshuis gesit kan word indien koshuisgelde nie betaal word nie. In hierdie artikel word besin oor die regsgeldigheid ... -
Cavinula lilandae (Bacillariophyta), a new diatom species from the Congo Basin, Central Africa
(Taylor & Francis, 2013)Cavinula lilandae, a small new diatom from the Congo Basin in Central Africa, was observed in acid riverine habitats in an almost pristine tropical rain forest. It occurred in a periphytic diatom community dominated by ... -
