Nanostructured europium-doped layered lithium manganese oxide as a prospective cathode material for aqueous lithium-ion battery
(Elsevier, 2023)
As the world moves to greener and renewable energy generation technologies, scientific researchers are facing a great challenge of concurrently developing energy storage materials with a low production cost, environmentally ...
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 ...
Synthesis of hydroxy sodalite from coal fly ash for biodiesel production from waste-derived maggot oil
(MDPI, 2019)
Zeolites are aluminosilicate crystalline materials known for their unique characteristics, and have been prominent for nearly half a century due to their wide and important industrial applications. The production of zeolites, ...
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 ...
Electrocatalytic sensor devices: (I) cyclopentadienylnickel(II) thiolato Schiff base monolayer self-assembled on gold
(Elsevier, 2004)
The fabrication of a self-assembled monolayer (SAM) of a cyclopentadienylnickel(II) thiolato Schiff base compound, [Ni(SC6H4NC(H)C6H4
OCH2CH2SMe)( 5-C5H5)]2 on a gold electrode is described. Effective electronic communication ...
Quantum dot nanotoxicity investigations using human lung cells and toxor electrochemical enzyme assay methodology
(American Chemical Society, 2017)
Recent studies have suggested that certain
nanomaterials can interfere with optically based cytotoxicity
assays resulting in underestimations of nanomaterial toxicity. As
a result there has been growing interest in the ...
The potential of leucosidea sericea against propionibacterium acnes
(Elsevier, 2014)
The present study reports on the potential of Leucosidea sericea addressing acne vulgaris. Four known compounds namely phytol acetate, triacontanol, phytol and alpha kosin and one new compound namely, (E)-3,7,11,15-tetra ...
