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. ...
Recent developments in microfiltration and ultrafiltration of fruit juices
(Elsevier, Amsterdam, 2017)
This article provides an overview of recent developments and the published literature in microfiltration (MF) and ultrafiltration (UF) of fruit juices. In this review, we summarize studies by relating basic concepts of ...
Natural sorbents modified by divalent Cu2+- and Zn2+- ions and their corresponding antimicrobial activity
(Elsevier Science Bv, Amsterdam, 2017)
The objective of this study was to investigate the modification of materials used in wastewater treatment for possible antimicrobial application(s). Granulated activated carbon (GAC) and natural clinoptilolite (CLI) were ...
Formulation and characterization of nanofibers and films with carvedilol prepared by electrospinning and solution casting method
(Elsevier Science Bv, Amsterdam, 2017)
The preparation and characterization of films and nanofibers with carvedilol as a poorly water-soluble drug in poly (ethylene oxide) (PEO) polymer were investigated. Films are prepared by solution casting method, and ...
Evaluation of the Quality of Clothing Fabrics in Terms of Their Compression Behaviour before and after Abrasion
(Korean Fiber Soc, Seoul, 2017)
In this work, the compression behaviour of clothing woven fabrics, before and after abrasion on the Martindale's device, has been examined. Plain and 3/1 twill weave fabrics from cotton and cotton/polyester fiber blends ...
In vitro investigation of electrophoretically deposited bioactive hydroxyapatite/chitosan coatings reinforced by graphene
(Elsevier Science Inc, New York, 2017)
Graphene (Gr) and natural polymer chitosan (CS) were introduced to hydroxyapatite (HAP) to produce a three-component composite coating, which was fabricated by cathodic electrophoretic deposition on Ti substrates in an ...
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 ...
Mechanism of adsorption of Cu2+ and Zn2+ on the corn silk (Zea mays L.)
(Elsevier, Amsterdam, 2017)
In this study the novel biosorbent - raw corn silk (CS) was investigated for Cu2+ and Zn2+ removal from aqueous solutions. The physical and chemical properties of CS were determined by SEM - EDX and ATR - FTIR techniques. ...
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 ...
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 ...
