Conventional and spark-plasma sintering of cordierite powders synthesized by sol-gel methods
(Elsevier Sci Ltd, Oxford, 2013)
Cordierite powders synthesized by colloidal and alkoxide sol-gel methods were conventionally and spark-plasma sintered. The powders for the sintering investigations were obtained by calcination of the gels at a temperature ...
Impregnation of cotton fabric with pyrethrum extract in supercritical carbon dioxide
(Elsevier Science Bv, Amsterdam, 2017)
This study discusses a possibility of cotton fabric impregnation with pyrethrum extract as a tick repellent in supercritical carbon dioxide. A solubility of pyrethrum extract in supercritical carbon dioxide has been ...
Ex-situ sensitization of ordered TiO2 nanotubes with CdS quantum dots
(Elsevier Sci Ltd, Oxford, 2015)
Ordered titania nanotubes (pore diameter approximate to 90 nm and wall thickness approximate to 10 nm) were obtained by the anodization technique and used for the ex-situ deposition of cadmium sulfide quantum dots (CdS ...
Isopiestic determination of the osmotic and activity coefficients of the {yMg(NO3)(2) + (1-y)MgSO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2017)
Isopiestic (vapor pressure) measurements were made for aqueous mixtures of Mg(NO3)(2) and MgSO4 at T = (298.15 +/- 0.01) K with Mg(NO3)(2) ionic strength fractions y = (0.19691, 0.42542, 0.60113, 0.79583, and 1), along ...
Improved beta-amylase production on molasses and sugar beet pulp by a novel strain Paenibacillus chitinolyticus CKS1
(Elsevier, Amsterdam, 2016)
Molasses and sugar beet pulp, by-products in sugar industry, are produced in large amounts annually which create disposal problems. High sugar content in sugar beet molasses enables its use for fermentations while sugar ...
Photocatalytic Ability of Visible-Light-Responsive TiO2 Nanoparticles
(Amer Chemical Soc, Washington, 2016)
The synthetic procedures for preparation of free-standing and attached to polymer support surface modified TiO2 nanoparticles (NPs) with absorption extended into the visible spectral region due to charge transfer complex ...
Antioxidant Protective Effects of Mushroom Metabolites
(Bentham Science Publ Ltd, Sharjah, 2013)
Global industrialization and agricultural development are related to the release of various pollutants into the environment including huge amounts of free radicals, which are associated with the occurrence of various ...
In situ generation of Ag nanoparticles on polyester fabrics by photoreduction using TiO2 nanoparticles
(Springer, New York, 2013)
This study discusses the possibility of in situ generation of Ag nanoparticles on polyester fabric by photoreduction of Ag+ ions with deposited TiO2 nanoparticles in the presence of amino acid alanine and methyl alcohol. ...
Modelling current efficiency in an electrochemical hypochlorite reactor
(Elsevier, Amsterdam, 2015)
A mathematical model was set up for anodic, cathodic and overall current efficiencies of an electrochemical cell for hypochlorite production acting as an ideal stirred reactor. A 0.06-0.20 mol dm(-3) NaClO hypochlorite ...
The removal of Zn2+, Pb2+, and As(V) ions by lime activated fly ash and valorization of the exhausted adsorbent
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
This study focuses on the use of raw fly ash (FA) and modified fly ash - activated by lime (MFA), as effective and low-cost adsorbents for the removal of heavy metals (Zn2+, Pb2+ and As(V)), followed by the revalorization ...
