• New model to capture the conversion of flow from confined to unconfined 

  Morakaladi, Makosha Ishmaeline Charlotte (University of the Free State, 2020-01)

  The conversion of flow from confined to unconfined aquifers, while it has attracted the attention of many researchers within and outside of the field of geo-hydrology, although many results and mathematical models have ...

• Modelling groundwater flow in a confined aquifer with dual layers 

  Chaka, Disebo Venoliah (University of the Free State, 2020-01)

  Groundwater flow occurring in a confined aquifer has been modelled in the past using deterministic mathematical models such as the Theis (1935) equation providing fundamental solutions. However, for this model to be ...

• Metal exchange of ZIF-8 and ZIF-67 nanoparticles with Fe(II) for enhanced photocatalytic performance 

  Mphuthi, Lehlonoholo E.; Erasmus, Elizabeth; Langner, Ernst H. G. (American Chemical Society, 2021)

  Zeolitic imidazolate frameworks (ZIFs), such as ZIF-8 and ZIF-67, were found to be efficient catalysts. However, ZIFs are not used much in photocatalysis due to their low photocatalytic activity for most reactions. The ...

• Plans and interventions of South African Grade 1 educators during the 2020 lockdown period 

  Grobler, Annemie (OpenED Network, 2021)

  The extended lockdown in 2020 found South African educators employing innovative strategies to teach and assess Foundation Phase learners. Educators had to make do with reduced hours in the classroom and experienced new ...

• Isotherm, kinetic, thermodynamics and reusability data on the adsorption of antidepressant onto silver nanoparticle-loaded biowaste 

  Akpomie, Kovo G.; Conradie, Jeanet (Elsevier Inc., 2021)

  There has been an increase in the use of antidepressant drugs owing to significant economic challenges across the globe. Consequently, the increase in production of such drugs has impacted pharmaceutical pollution of ...
