Characterisation of a polyaromatic PBI blend membrane for SO2 electrolysis
(Elsevier, 2015)The application of a polyaromatic acid–base blend membrane from partially fluorinated and sulfonated aromatic polyether and the polybenzimidazole F6PBI has been investigated for hydrogen production using SO2 electrolysis. ... -
Characterisation of a proton exchange membrane electrolyser using electrochemical impedance spectroscopy
(North-West University, 2012)Hydrogen is a promising energy carrier and a possible replacement for fossil fuel energy sources in the future. Hydrogen has the highest energy content per unit weight of any known fuel. The proton exchange membrane (PEM) ... -
Characterisation of a topotype and other populations of Hemicriconemoides strictathecatus Esser, 1960 (Nematoda: Criconematidae) from Florida with description of H. phoenicis sp. n. from the USA
(Brill Academic Publishers, 2015)The results of morphological and molecular analyses of a Florida topotype and other populations of Hemicriconemoides strictathecatus showed that this sheathoid nematode consists of two morphotypes, both with an average ... -
Characterisation of a UHF fading channel for an RFID-based EVI system
(North-West University, 2008)On the request of government's transport authority, SANRAL, the North-west University was requested to investigate the applicability of using passive ultra-high frequency (UHF) radio-frequency identification (RFID) for ... -
Characterisation of air masses passing over the Vredefort Dome world heritage site
(North-West University (South Africa), 2015)In 2007, it was announced that the Vredefort Dome will be proclaimed South Africa’s seventh UNESCO (United Nations Educational, Scientific and Cultural Organisation) world heritage site. It is the largest and second oldest ... -
Characterisation of airborne dust in a South African opencast iron ore mine : a pilot study
(2013)The iron ore mining industry makes use of various processes that result in the release of airborne dust into the surrounding atmosphere where workers are exposed, to produce a final product. The deposition in the lung and ... -
Characterisation of airborne dust in South African underground and opencast coal mines : a pilot study
(2015)Dust is a well-known occupational hygiene challenge and has been throughout the years, especially in the coal mining industry. The hazards arising from coal dust will differ between geographical areas due to the unique ... -
Characterisation of ambient Total Gaseous Mercury concentrations over the South African Highveld
(Elsevier, 2019)Mercury is considered a ubiquitous, toxic, and global pollutant. In this study, ambient Total Gaseous Mercury (TGM) concentrations over the South African Highveld are characterised. Studies on ambient mercury in this region ... -
Characterisation of an industrial Søderberg electrode
(North-West University (South Africa), 2023)Søderberg electrode management (together with the initial design of the electrode system) is commonly considered as one of the most important aspects of profitable and safe submerged arc furnace operation, with some even ... -
Characterisation of and exposure of workers to tailings dust at South African platinum mines
(Mine Ventiliation Society of South Africa, 2009)The National Institute for Occupational Safety and Health (NIOSH) has conducted research to improve the ventilation of large-opening mines whose entries are at least 93m2 (1,000 ft2). The ventilation of large-opening mines ... -
Characterisation of cyclists' willingness to pay for green initiatives at Africa's largest cycle tour
(AOSIS, 2016)The Cape Argus Pick n Pay Cycle Tour is a major event on the road cycling calendar. The majority of cyclists travel significant distances and participation produces a substantial carbon footprint. This paper examines ... -
Characterisation of dark chilling effects on the functional longevity of soybean root nodules
(North-West University, 2012)A large proportion of the world’s nitrogen needs is derived from symbiotic nitrogen fixation (SNF), which contributes substantially to agricultural sustainability. The partnership between legumes and rhizobia result in the ... -
