Electrokinetic and sorption properties of hydrogen peroxide treated flax fibers (Linum usitatissimum L.)
(Cellulose, 2021)
Hydrogen peroxide represents an ecologically and economically acceptable agent for bleaching of flax fibers. The influence of hydrogen peroxide treatment under different conditions, i.e. hydrogen peroxide concentrations ...
Adsorption of arsenate on iron(III) oxide coated ethylenediamine functionalized multiwall carbon nanotubes
(Elsevier Science Sa, Lausanne, 2012)
New criteria in assessing the quality of drinking water reduced the maximum permissible concentration of arsenic from 50 mu g L-1 to 10 mu g L-1 and set a requirement for the development of new technologies for arsenic ...
Unsupervised classification and multi-criteria decision analysis as chemometric tools for the assessment of sediment quality: A case study of the Danube and Sava River
(Elsevier, Amsterdam, 2016)
The aim of this study was to evaluate the quality of freshwater sediments by means of three chemometric techniques for multi-criteria analysis and decision: self-organizing network (SON), self-organizing map (SOM) and ...
Tautomerism in 8-(phenyldiazenyl)quinolin-5-ol: An attempt for pH activated rotary switch
(Elsevier Sci Ltd, Oxford, 2020)
The tautomerism of 8-(phenyldiazenyl)quinolin-5-ol has been studied by a combination of theoretical (DFT calculations) and experimental (UV-Vis and NMR) methods. The detailed study of neutral molecules has shown that the ...
Biodiesel density and derived thermodynamic properties at high pressures and moderate temperatures
(Elsevier Sci Ltd, Oxford, 2016)
Knowledge of the basic thermodynamic properties of biodiesel under different conditions is necessary because of its wide use as a substitute for fossil fuels. The viscosities and refractive indices of the methyl and ethyl ...
Synthesis and antimicrobial properties of Zn-mineralized alginate nanocomposites
(Elsevier Sci Ltd, Oxford, 2017)
New bioactive and antimicrobial biomaterials were produced by alginate-mediated biomineralization with Zn-mineral phase. The synthesis procedure is simple, cost-effective and resulted in. two different Zn-mineralized ...
Mineralized agar-based nanocomposite films: Potential food packaging materials with antimicrobial properties
(Elsevier Sci Ltd, Oxford, 2017)
New mineralized, agar-based nanocomposite films (Zn-carbonate and Zn-phosphate/agar) were produced by a combination of in situ precipitation and a casting method. The presence of minerals significantly influenced the ...
Mathematical modeling of heavy metal ions (Cd2+, Zn2+ and Pb2+) biosorption by chemically modified short hemp fibers
(Elsevier Science Sa, Lausanne, 2011)
Biosorption, an innovative and low-cost effective method for removal of heavy metal ions from wastewaters, primarily depends on the diffusion of metal ions through the porous structure of sorbent and the resistance effects ...
Urban population exposure to tropospheric ozone: A multi-country forecasting of SOMO35 using artificial neural networks
(Elsevier Sci Ltd, Oxford, 2019)
Urban population exposure to tropospheric ozone is a serious health concern in Europe countries. Although there are insufficient evidence to derive a level below which ozone has no effect on mortality WHO (World Health ...
Bioactive glass-ceramics prepared by powder sintering and crystallization of polyphosphate glass containing strontium
(Elsevier Sci Ltd, Oxford, 2017)
Melt-quenching method was employed for obtaining a glass-ceramic with the following composition 42P(2)O(5). 40CaO.5SrO.10Na(2)O.3TiO(2) (mol%) glass. The crystallization and sintering behavior of glass have been studied ...
