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 ...
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 ...
Antibacterial and anti-inflammatory effects of Syzygium jambos L. (Alston) and isolated compounds on acne vulgaris
(BioMed Central, 2013)
Acne vulgaris is a chronic skin disorder leading to inflammation as a result of the production of
reactive oxygen species due to the active involvement of Propionibacterium acnes (P. acnes) in the infection site of
the ...
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 ...
