Improved bi-functional oxygen electrocatalytic performance of PteIr alloy nanoparticles embedded on MWCNT with Pt-enriched surfaces
(Energy, 2020)
Multi-walled carbon nanotube supported PteIr nanoparticles (PteIr/MWCNT) with different elemental ratios were synthesized by one-pot co-reduction approach under ambient conditions. The PteIr catalysts exhibit improved ...
A review on crucibles for induction melting of titanium alloys
(Elsevier, 2020)
This review highlights the state of art progress in crucible designs which have been identified as showing potential for induction melting three groups of titanium alloys based on the systems; Ti–Al, Ti–Ni, as well as ...
Potential of resampled multispectral of data for detecting desmodium-brachiaria intercropped with maize in a push-pull system
(ISPRS, 2020)
Poor crop yields remain one of the main causes of chronic food insecurity in Africa. This is largely caused by insect pests, weeds, unfavourable climatic conditions and degraded soils. Weed and pest control, based on the ...
Antibacterial activity of biogenic silver and gold nanoparticles synthesized from Salvia africana-lutea and Sutherlandia frutescens
(Nanotechnology, 2020)
Nanoparticles (NPs) synthesized using various chemical and physical methods are often cytotoxic which restricts their use in biomedical applications. In contrast, metallic biogenic NPs synthesized using biological systems ...
Treatment of acid mine drainage with coal fly ash in a jet loop reactor pilot plant
(Minerals Engineering, 2020)
A 1500 L batch jet loop reactor pilot plant was designed, constructed, and evaluated for performance in the treatment of acid mine drainage (AMD) using coal fly ash with a view to optimize its operation and generate ...
Spin coating immobilisation of C-N-TiO2 Co-Doped nano catalyst on glass and application for photocatalysis or as electron transporting layer for perovskite solar cells
(MDPI, 2020)
Producingactivethinfilmscoatedonsupportsresolvesmanyissuesofpowder-basedphoto catalysis and energy harvesting. In this study, thin films of C-N-TiO2 were prepared by dynamic spin coating of C-N-TiO2 sol-gel on glass support. ...
Effects of inorganic salt solutions on vigour, viability, oxidative metabolism and germination enzymes in aged cabbage and lettuce seeds
(MDPI, 2020)
This study assessed the potential of pre-hydration treatment with aqueous solutions
(electrolysed [cathodic water; CW] and non-electrolysed) prepared from four different inorganic
ion combinations: 1 mM CaCl2, 1 m CaCl2 ...
Metal oxide (Co3O4 and Mn3O4) impregnation into S, N-doped graphene for oxygen reduction reaction (ORR)
(MDPI, 2020)
To address aggravating environmental and energy problems, active, efficient, low-cost, and robust electrocatalysts (ECs) are actively pursued as substitutes for the current noble metal ECs. Therefore, in this study, we ...
Antibacterial activity of rationally designed antimicrobial peptides.
(Hindawi, 2020)
Many infectious diseases are still prevalent in the world’s populations since no effective treatments are available to eradicate them.
e reasons may either be the antibiotic resistance towards the available therapeutic ...
HIV-1 diversity and the implementation of integrase strand-transfer inhibitors as part of combination antiretroviral therapy
(SAMA, 2020)
: The integrase (IN) strand-transfer inhibitor (InSTI)
dolutegravir (DTG) is now recommended by the World Health
Organization as part of salvage and/or first-line combination
antiretroviral therapy (cART).[1] DTG has a ...
