Hall measurements on carbon nanotube paper modified with electroless deposited platinum
(Springer, 2010)
Carbon nanotube paper, sometimes referred to
as bucky paper, is a random arrangement of carbon nanotubes meshed into a single robust structure, which can be
manipulated with relative ease. Multi-walled carbon
nanotubes ...
Synthesis and characterisation of a polysulfone-polyvinyl alcohol hydrogelic material
(ESG, 2016)
Hydrogels are flexible materials that have found a niche in membrane science owing to their ability to
absorb water without dissolving. The synthesis of polyvinyl alcohol-polysulfone hydrogel in the
presence of N-hydroxy ...
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, ...
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 ...
Waste minimization protocols for the process of synthesizing zeolites from South African coal fly ash
(MDPI, 2013)
Production of a high value zeolite from fly ash has been shown to be an avenue
for the utilization of South African fly ash which presently constitutes a huge disposal
problem. The synthesis of zeolites Na-P1 and analcime ...
Underpotential deposition of SnBi thin films for sodium ion batteries: The effect of deposition potential and Sn concentration
(Elsevier, 2019)
Bimetallic SnBi film was deposited on a Cu foil substrate via the electrochemical atomic layer deposition
(E-ALD) technique. The deposition attainment of Sn and Bi were investigated using cyclic voltammetry
(CV) and ...
Silver–zinc oxide nanocomposite antiseptic from the extract of Bidens pilosa
(Springer, 2019)
Silver nanoparticles (Ag-NPs), zinc oxide (ZnO-NPs) and zinc oxide–silver (ZnO–Ag-NPs) were biosynthesized based on
the rich matrix of alkaloids, flavones, tannins capping/stabilizing agents present in Bidens pilosa ...
Eliminating micro-porous layer from gas diffusion electrode for use in high temperature polymer electrolyte membrane fuel cell
(Elsevier, 2017)
In this work, we report a simple strategy to improve the performance of high temperature polymer
electrolyte membrane fuel cell (HT-PEMFC) by eliminating the micro-porous layer (MPL) from its gas
diffusion electrodes ...
