Influence of the synthesis parameters on the properties of the sepiolite-based magnetic adsorbents
(Elsevier Science Bv, Amsterdam, 2017)
The magnetic nanocomposites (MNCs), used as adsorbents for Cd2+ ions, were prepared by a co-precipitation method using both the untreated natural (SEP) and the partially acid-activated (ASEP) sepiolites as supports for ...
Shaped Co2+ doped TiO2 nanocrystals synthesized from nanotubular precursor: Structure and ferromagnetic behavior
(Springeropen, London, 2017)
Co2+ doped TiO2 nanocrystals were synthetized by a hydrothermal treatment procedure applied to precursor dispersion of titania nanotubes and Co2+ ions. Mixture of polygonal and prolate spheroid-like nanocrystals was obtained. ...
Volumetric and viscometric study and modelling of binary systems of diethyl tartrate and alcohols
(Elsevier Science Bv, Amsterdam, 2017)
Density, viscosity, refractive index and speed of sound have been measured for the pure ester diethyl tartrate at atmospheric pressure and over the temperature range from 288.15 K to 323.15 K. Detailed investigation regarding ...
Towards understanding intermolecular interactions in hydantoin derivatives: the case of cycloalkane-5-spirohydantoins tethered with a halogenated benzyl moiety
(Royal Society of Chemistry, 2017)
A series of cycloalkane-5-spirohydantoins bearing a halogeno substituted benzyl group (X = Cl and Br) in position 3 has been synthesized and their structures (1-6) have been determined by a single crystal X-ray diffraction ...
The influence of alkaline cations on the mechanism and kinetics of dehydration of polymeric phthalatocuprate(II) dihydrates
(Elsevier Science Bv, Amsterdam, 2017)
Thermal dehydration of two heterometallic complexes containing dianion of phthalic acid, pht, Na-2[Cu(pht)(2)] center dot 2H(2)O, 1, and K-2[Cu(pht)(2)] center dot 2H(2)O, 2, was investigated under non-isothermal conditions. ...
High pressure densities and derived thermodynamic properties for the (n-heptane plus n-octane plus ethanol) ternary system
(Academic Press Ltd- Elsevier Science Ltd, London, 2017)
The density of the ternary system (n-heptane + n-octane + ethanol) at temperatures from (293.15 to 373.15) K and at pressures from (0.1 to 40) MPa was experimentally determined at twelve compositions and the results are ...
Experimental Investigation and Modeling of Thermophysical Properties of Pure Methyl and Ethyl Esters at High Pressures
(Amer Chemical Soc, Washington, 2017)
Densities, speeds of sound, and refractive indices of methyl laurate, ethyl laurate, ethyl myristate, and ethyl oleate in the temperature range 288.15-343.15 K and viscosities from 288.15 to 373.15 K were measured at ...
Voltammetric behavior and determination of the macrolide antibiotics azithromycin, clarithromycin and roxithromycin at a renewable silver - amalgam film electrode
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
The renewable silver-amalgam film electrode (Hg(Ag)FE) was applied for voltammetric characterization and determination of semi-synthetic macrolide antibiotics azithromycin (AZI), clarithromycin (CLA) and roxithromycin (ROX) ...
Immobilization of Candida antarctica lipase B on kaolin and its application in synthesis of lipophilic antioxidants
(Elsevier Science Bv, Amsterdam, 2017)
Lipase B from Candida antarctica was immobilized by adsorption onto laboratory prepared metakaolin. This support has great potential for enzyme immobilization since it has good mechanical characteristics and thermal stability ...
Volumetric and viscometric properties of binary liquid mixtures as potential solvents for flue gas desulfurization processes
(Academic Press Ltd- Elsevier Science Ltd, London, 2017)
Desulphurization processes (FGD) of flue gases from the thermal power and industrial plants, based on organic liquid solvents with mechanism of physical absorption (tetraethylene glycol dimethyl ether) or combination of ...
