Influence of pastes containing casein phosphopeptide-amorphous calcium phosphate on surface of demineralized enamel
(Sage Publications Ltd, London, 2014)
Purpose: The purpose of the study was to evaluate the surface characteristics of demineralized enamel after treatment with pastes containing casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) or casein ...
Crystallization tests bench
(Maik Nauka/Interperiodica/Springer, New York, 2013)
A model of an air-cooled tube ("air-heat saw") installed in a laboratory tube furnace is presented. The setup ("crystallization tests bench") allows easy regulation and simultaneous crystallization tests of a series of ...
Removal of Mg from spring water using natural clinoptilolite
(Mineralogical Soc, Twickenham, 2012)
Natural zeolitic tuff from Brus (Serbia) consisting mostly of clinoptilolite (about 90%) has been investigated for the reduction of the Mg concentration in spring water. The sorption capacity of the zeolite is relatively ...
In Silico Study of Chromatographic Lipophilicity Parameters of 3-(4-Substituted Benzyl)-5-Phenylhydantoins
(Combinatorial Chemistry and High Throughput Screening, 2016)
New synthesized compounds, particularly those with biological activity, are potential drug candidates. This article describes experimental studies performed to estimate lipophilicity parameters of new 3-(4-substituted ...
Enhanced Arsenic Sorption by Hydrated Iron (III) Oxide-Coated Materials-Mechanism and Performances
(Water Environment Federation, 2011)
Mechanism and performances of arsenic(III) [As(III)] and arsenic(V) [As(V)] sorption onto hydrated iron(III) oxide (HFO)-coated materials were investigated at neutral pH where arsenic occurs in both molecular and ionic ...
Solvent, structural, quantum chemical study and antioxidative activity of symmetrical 1-methyl-2,6-bis[2-(substituted phenyl)ethenyl]pyridinium iodides
(Springer, New York, 2018)
15 symmetric 1-methyl-2,6-bis[2-(substituted phenyl)ethenyl]pyridinium iodides were synthesized in this work. Their structures were characterized using IR, H-1 and C-13 NMR, and UV-Vis spectroscopy. DFT calculations indicated ...
Theoretical modeling of sorption of metal ions on amino-functionalized macroporous copolymer in aqueous solution
(Springer, New York, 2019)
With regard to the harmful effects of heavy metals on human health and the environment, the demand for synthesis and investigation of macromolecules with large capacity of harmful substances sorption is ever greater. ...
Lead(ii) removal from aqueous solutions by Serbian zeolitic tuff
(Gheorghe Asachi Technical University of Iasi, Romania, 2017)
The present study was aimed at examining the ability of the natural zeolitic tuff from the Zlatokop deposit in Serbia to remove Pb(II) ions from aqueous solutions under various conditions. It has been found that the ...
The electrochemical deposition of Zn-Mn coating from choline chloride-urea deep eutectic solvent
(Taylor & Francis Ltd, Abingdon, 2017)
Electrochemical and microscopic techniques were used for the characterisation of Zn-Mn coatings electrodeposited from choline chloride-urea deep eutectic solvent. Cyclic voltammograms show that there was no discernible Mn ...
Chromatographic and Computational Assessment of Potential Biological Activity of N-(Substituted Phenyl)-2-Chloroacetamides Applying Multivariate Methods
(Taylor & Francis Inc, Philadelphia, 2015)
The lipophilicity of the newly synthesized N-(substituted phenyl)-2-chloroacetamides, as the most commonly used molecular descriptor of a potential biological activity was the subject of research. The lipophilicity of the ...
