The iron(III)-modified natural zeolitic tuff as an adsorbent and carrier for selenium oxyanions
(Elsevier, Amsterdam, 2014)
Se(IV) and Se(VI) anions are the dominant species of Se existing in aqueous systems. In this study, the iron(III)-modified natural zeolitic tuff (Fe-CLI) from the Serbian deposit Zlatokop has been investigated as an adsorbent ...
Preparation, characterization and mechanical properties of Bi12SiO20-PMMA composite films
(Elsevier Science Sa, Lausanne, 2014)
This paper investigates processing and characterization of polymer composite material PMMA-Bi12SiO20 (BSO). Thin films of pure PMMA and composites with 0.5 and 1.0 wt% of Bi12SiO20 powder were made using solution casting ...
Electrochemical study of corrosion behavior of graphene coatings on copper and aluminum in a chloride solution
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
Electrochemical characteristics and corrosion behavior of graphene coatings on Cu and Al in a 0.1 M NaCl solution were investigated. The graphene coatings were deposited on a Cu surface by chemical vapor deposition. Multiple ...
Carbon materials from waste short hemp fibers as a sorbent for heavy metal ions - Mathematical modeling of sorbent structure and ions transport
(Elsevier Science Sa, Lausanne, 2014)
Carbonized hemp fibers obtained by carbonization of origin and chemically modified waste hemp fibers was used as a low-cost sorbent for heavy metals removal. The efficiency of carbonized hemp fiber samples as a sorbent was ...
Pharmacokinetics and toxicity predictors of new s-triazines, herbicide candidates, in correlation with chromatogrpahic retention constants
(American Chemical Society, 2014)
Herbicides, which are ubiquitously present in soil and food, have been proven to cause human health hazard effects, hence development of new herbicide-active compounds is recommended. In this paper, nine 2,4-bis(cycloalk ...
Preparation of cellulosic fibers with biological activity by immobilization of trypsin on periodate oxidized viscose fibers
(Springer, Dordrecht, 2014)
In this study, a biologically active fibrous material was designed by immobilizing trypsin on viscose fibers. The viscose yarn was first oxidized with sodium periodate to produce aldehyde groups and then employed as a ...
In situ chitosan gelation initiated by atmospheric plasma treatment
(Elsevier Ltd., 2014)
This work reports on the feasibility of atmospheric dielectric barrier discharge (DBD) plasma as a novel synthetic pathway for the liquid phase gelation of chitosan. The DBD plasma chitosan gelation process did not ...
Cytotoxicity studies of novel Ag/alginate nanocomposites aimed for wound treatment
(Wiley-Blackwell, Hoboken, 2014)
Modelling of dissolved oxygen in the Danube River using artificial neural networks and Monte Carlo Simulation uncertainty analysis
(Elsevier Science Bv, Amsterdam, 2014)
This paper describes the training, validation, testing and uncertainty analysis of general regression neural network (GRNN) models for the forecasting of dissolved oxygen (DO) in the Danube River. The main objectives of ...
Chitosan microbeads for encapsulation of thyme (Thymus serpyllum L.) polyphenols
(Elsevier Sci Ltd, Oxford, 2014)
In this work chitosan microbeads were prepared by emulsion technique and loaded with thyme polyphenols by diffusion from an external aqueous solution of Thymus serpyllum L. The effects of concentrations of chitosan (1.5-3% ...
