Surface-modified polyacrylonitrile nanofibers as supports
(Springer Verlag, 2017)
Polyacrylonitrile nanofibers (PAN-nfs) are one of the most studied nanofibres because of their excellent characteristics, such as good mechanical strength, chemical resistance, and good thermal stability. Due to the easy ...
Synthesis and characterization of carbon doped TiO2 photocatalysts supported on stainless steel mesh by sol-gel method
(Korean Carbon Society, 2017)
This study synthesized pure anatase carbon doped TiO2 photocatalysts supported on a stainless
steel mesh using a sol-gel solution of 8% polyacrylonitrile (PAN)/dimethylformamide
(DMF)/TiCl4. The influence of the pyrolysis ...
Desalination and seawater quality at Green Point, Cape Town: A study on the effects of marine sewage outfalls
(Academy of Science of South Africa (ASSAf), 2017)
This paper presents our collection methods, laboratory protocols and findings in respect of sewage pollution
affecting seawater and marine organisms in Table Bay, Cape Town, South Africa, then moves to consider ...
Treatment of persistent organic pollutants in wastewater using hydrodynamic cavitation in synergy with advanced oxidation process
(Springer, 2017)
Persistent organic pollutants (POPs) are very tenacious wastewater contaminants. The consequences of their existence have been acknowledged for negatively affecting the ecosystem with specific impact upon endocrine disruption ...
Plasmonic metal decorated titanium dioxide thin films for enhanced photodegradation of organic contaminants
(Elsevier, 2017)
Photocatalysis using titanium dioxide as photocatalyst is an efficient way for the removal of organic
contaminants in water using solar energy. In this study, thin
films of copper and silver were deposited on
fused ...
Silver/carbon codoped titanium dioxide photocatalyst for improved dye degradation under visible light
(Hindawi Publishing Corporation, 2017)
Herein, we report the synthesis of quartz supported TiO2 photocatalysts codoped with carbon and silver through the hydrolysis of titanium tetrachloride followed by calcination at 500°C. The prepared samples were characterized ...
Effect of nanoparticle (Pd, Pd/Pt, Ni) deposition on high temperature hydrogenation of Ti-V alloys in gaseous flow containing CO
(Elsevier B.V., 2017)
The hydrogenation properties of Ti-V hydrides coated with nanoparticles have been studied in gaseous mixtures of argon and hydrogen with and without additions of 1% CO. Nanoparticles of Pd, Ni, and co-deposited Pd/Pt with ...
Antibacterial activities of bacteria isolated from the marine sponges Isodictya compressa and Higginsia bidentifera collected from Algoa Bay, South Africa
(MDPI AG, 2017)
Due to the rise inmulti-drug resistant pathogens and other diseases, there is renewed interest
in marine sponge endosymbionts as a rich source of natural products (NPs). The South African marine
environment is rich in ...
Complexation-based detection of nickel(ii) at a graphene-chelate probe in the presence of cobalt and zinc by adsorptive stripping voltammetry
(MDPI, 2017)
The adsorptive stripping voltammetric detection of nickel and cobalt in water samples
at metal film electrodes has been extensively studied. In this work, a novel, environmentally
friendly, metal-free electrochemical ...
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 ...
