Nanostructured silicon derived from an agricultural residue bagasse ash via magnesiothermic reduction method
(MDPI, 2023)
This study presents the magnesiothermic reduction of silica into silicon. This reduction
process occurs at a lower reaction temperature than its carbothermal counterpart. Furthermore, silica
was extracted from sugarcane ...
Spray‐pyrolyzed Cd‐substituted kesterite thin‐films for photovoltaic applications: Post annealing conditions and property studies
(Elsevier, 2023)
Kesterite materials were investigated for their suitability as absorber layers for thin-film photovoltaic cells. Thin-
films of copper cadmium zinc tin sulfide (Cu2CdxZn1-xSnS4) were prepared by spray pyrolysis on soda-lime ...
Antimicrobial activity of the secondary metabolites isolated from a South African red seaweed, laurencia corymbosa
(MDPI, 2023)
South Africa’s highly diverse marine biota includes several endemic marine red algae of the Laurencia genus. Cryptic species and morphological variability make the taxonomy of Laurencia plant challenging, and a record of ...
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 ...
Progress on perovskite materials for energy application
(Elsevier, 2021)
Energy underlies the human development and welfare. Today energy depends on combustion of fossil fuels (coal,
natural gas, oil) sources. These sources have not only led to severe environmental issues because it emits
greenhouse ...
Effects of film thickness of ald-deposited al2o3, zro2 and hfo2 nano-layers on the corrosion resistance of ti(n,o)-coated stainless steel
(MDPI, 2023)
The goal of this stydy was to explore the potential of the enhanced corrosion resistance of
Ti(N,O) cathodic arc evaporation-coated 304L stainless steel using oxide nano-layers deposited by
atomic layer deposition (ALD). ...
Enhanced photovoltaic effects of microwave-assisted polyolsynthesized Cu2(Pd/Zn)SnS4 kesterite nanoparticles
(Elsevier, 2023)
Kesterite materials show excellent optical and semiconductive properties for use as petype absorber
layer in photovoltaic (PV) applications, but they have a high open circuit voltage deficit (Voc,def) due to
high antisite ...
Sustainable fuels: Lower alcohols perspective
(Wiley, 2023)
In the coming years, energy sources will play a vital role in global development. Biofuels
made from sustainable sources are essential for the global economy's long-term
viability and the reduction of greenhouse gas ...
