Effect of inclusion of MOF-polymer composite onto a carbon foam material for hydrogen storage application

Author: Molefe, Lerato Y ; Musyoka, Nicholas M ; Ren, Jianwei ; Langmi, Henrietta W ; Mathe, Mahlanyane K ; Ndungu, PG Date: Aug 2020 Despite the extensive studies done on the remarkable characteristics of metal–organic frameworks (MOFs) for gas storage applications, several issues still preclude their widespread commercial lightweight applications. In most cases, MOF ... Read more
The generation of charge carriers in semi conductors – A theoretical study

Author: Kiarii, EM ; Govender, Krishna ; Ndungu, PG ; Govender, PG Date: Apr 2017 A systematic study of electronic and optical properties of titanium dioxide under visible light was simulated using the first principles calculations. Both electronic and optical properties were studied. The findings support the application ... Read more
Ionic self-assembly of porphyrin nanostructures on the surface of charge-altered track-etched membranes

Author: Mongwaketsi, N ; Ndungu, PG ; Nechaev, A ; Maaza, M ; Sparrow, R Date: Jan 2010 Track-etched polymer membranes are typically used as templates in the synthesis of various nanowires or nanotubes arrays. The unique advantages of track-etched membranes, such as uniform pore structure, excellent porosity, easily tailored ... Read more
Poly (2, 6-dimethyl-1, 4-phenylene)/polysulfone anion exchange membrane blended with TiO2 with improved water uptake for alkaline fuel cell application

Author: Msomi, PF ; Nonjola, Patrick N ; Ndungu, PG ; Ramontja, J Date: Oct 2020 A series of anion exchange membranes (AEM) based on poly (2, 6-dimethyl-1, 4-phenylene) (PPO) and polysulfone (PSF) blended with TiO2 were prepared and investigated. The water uptake, swelling ratio, ion exchange capacity, ion conductivity ... Read more
Recent advances in titanium dioxide/graphene photocatalyst materials as potentials of energy generation

Author: Kiarii, EM ; Govender, Krishna ; Ndungu, PG ; Govender, PP Date: Jun 2018 The properties of TiO(sub2)/graphene/graphene oxides are examined in this article. The review summarises the recent theoretical and experimental novel approaches in the catalytic activity of TiO2/graphene interface. Imperative results at a ... Read more
Simulation from the first principal theory on the effect of supporting silica on graphene and the new composite material

Author: Kiarii, EM ; Govender, Krishna ; Ndungu, PG ; Govender, PP Date: Jul 2017 Silica has been used as support material with many photocatalytic materials. In this study, silica polymorphs on graphene and epoxy graphene were studied using Density Functional Theory (DFT) to determine the interfacial and optical properties ... Read more
Synthesis of porous polymer-based metal–organic frameworks monolithic hybrid composite for hydrogen storage application

Author: Molefe, Lerato Y ; Musyoka, Nicholas M ; Ren, Jianwei ; Langmi, Henrietta W ; Ndungu, PG ; Dawson, R ; Mathe, Mahlanyane K Date: Jan 2019 Herein, we report a simple method for the preparation of cross-linked polymer of intrinsic microporosity (PIM-1)/Materials Institute Lavoisier chromium (III) terephthalate [MIL-101(Cr)] monoliths which involves direct impregnation of PIM-1 ...
