F+ center exchange mechanism and magnetocrystalline anisotropy in Ni-doped 3C-SiC
(Elsivier, 2022)Towards the development of a magnetic semiconductor suitable for spintronic device applications in extreme environments, we explored the possibility of inducing magnetic interaction in SiC by doping Nickel. The X-ray ... -
Fabrication and characterization of electrospun waste polyethylene terephthalate blended with chitosan: A potential single-use material
(MDPI, 2023)Textile single-use products are dominantly used for hygiene and personal care, many of which are non-biodegradable and are frequently discarded into sewerage systems, thus causing blockages. Thus, there is a need to move ... -
Fabrication of AgCu/TiO2 nanoparticle-based sensors for selective detection of xylene vapor
(Royal Society of Chemistry, 2022)The design and fabrication of innovative nanostructured materials that could display improved sensitivity, selectivity, and rapid response/recovery characteristics still present significant scientific challenges. Herein ... -
Fabrication of polyoxometalate-modified palladium–nickel/reduced graphene oxide alloy catalysts for enhanced oxygen reduction reaction activity
(Royal Society of Chemistry, 2021)Designing advanced nanocatalysts for effectively catalyzing the oxygen reduction reaction (ORR) is of great importance for practical applications of direct methanol fuel cells (DMFCs). In this work, the reduced graphene ... -
Fabrication of silver‑coated PET track‑etched membrane as SERS platform for detection of acetaminophen
(Springer, 2021-09)In this study, silver nanoparticles (AgNPs) were immobilized on the surface of polyethylene terephthalate (PET) membrane using diethylenetriamine (DETA) as a chemical linker. The molecule of DETA was attached to the surface ... -
Fabrication, characterization, and photovoltaic performance of titanium dioxide/metal-organic framework composite
(Elsevier, 2022)The titanium dioxide-metal-organic framework (TiO2−MOF) composite was prepared using the sol-gel method for photovoltaic applications. Raman analyses showed the presence of MOF clusters in the TiO2 sol-gel network. Using ... -
Face-to-face versus online-based lectures: A covid-19 induced study on assessments
(Frontiers Media, 2022)There is much debate regarding the impact of COVID-induced lockdown on the standard of assessments, mainly since students were assessed at home via an online assessment platform. Regular orthodox lectures and assessments ... -
Face-to-face versus online-based lectures: A COVID-19 induced study on assessments
(Frontiers in Education, 2022)The students were found to be resilient in adapting to things and learning, online presentations, and computer-based assessments. No gender-based difference or advantage to adjusting to newly introduced blended learning ... -
Facile synthesis of NiSe2:α-Fe2O3 thin film: physical, optical and photoelectronic properties
(Thin Solid Films, 2023)In this study, a highly scalable approach to fabricating NiSe2:α-Fe2O3 heterojunction thin film in the absence of a dehydration step or lattice parameter matching was established. The attachment of NiSe2 to α-Fe2O3 leads ... -
Factors affecting the enrolment rate of students in Higher Education Institutions in the Gauteng province, South Africa
(SAGE, 2018)The purpose of this research is to investigate and analyse higher education institutions' enrolment and drop-out rates within the Gauteng province, South Africa. Large-scale secondary data from the General Household ... -
Factors and impacts of informal settlements residents' sanitation practices on access and sustainability of sanitation services in the policy context of Free Basic Sanitation
(IWA Publishing, 2020)Through the Free Basic Sanitation (FBSan) service policy, many informal settlements in South Africa have been provided with basic sanitation facilities. However, access to these facilities remains challenging for many ... -
Factors associated with antiretroviral treatment failure among people living with HIV on antiretroviral therapy in resource- poor settings: a systematic review and metaanalysis
(BMC, 2020)Background: Despite the increase in the number of people accessing antiretroviral therapy (ART), there is limited data regarding treatment failure and its related factors among HIV-positive individuals enrolled in HIV care ... -
