A comparative study of chromatographic lipophilicity and bioactivity parameters of selected spirohydantoins
(Taylor & Francis Inc, Philadelphia, 2020)
In this study, lipophilicity of 21 cycloalkylspiro-5-hidantoins was assessed. The overall goal of lipophilicity evaluation is preliminary investigation which should result in a decrease of the traditionally high attrition ...
TEMPO-oxidized cotton as a substrate for trypsin immobilization: impact of functional groups on proteolytic activity and stability
(Springer, Dordrecht, 2017)
Cotton fibers containing different amounts of aldehyde and carboxyl groups were prepared by varying TEMPO oxidation conditions and then employed as carriers for trypsin immobilization. Depending on the functional group ...
Isopiestic determination of the osmotic and activity coefficients of the {yKCl + (1-y)K2HPO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2011)
The osmotic coefficients of aqueous mixtures of KCl and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic vapor pressure method over the range of ionic strengths from (2.3700 to 11.250) mol . kg(-1) ...
Spatial and temporal distribution of pollution indices in marine surface sediments-a chemometric approach
(Environmental Science and Pollution Research, 2021)
Concentrations of As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, Zn, and Fe measured at forty locations in the Boka Kotorska Bay were used to monitor the spatial and temporal quality of sediment and to assess surface sediment contamination ...
Preliminary studies on controlled release of acetylsalycilic acid from membrane module
(Association of Chemical Engineers of Serbia, 2004)
Zeolite/Chitosan/Gelatin Films: Preparation, SupercriticalCO2Processing, Characterization, and Bioactivity
(Wiley, 2022)
Chitosan/gelatin and chitosan/gelatin/zeolite films prepared by solvent casting method were impregnated with a mixture of thymol and carvacrol using a green solvent, supercritical carbon dioxide at 35 °C and 30 MPa, during ...
Crystallographic, spectroscopic, thermal and computational studies of polymeric cobalt(II)-mellitate complex with 2,2 '-bipyridine
(Elsevier B.V., 2022)
Orange single crystals of new polymeric cobalt(II) complex {[Co(bipy)(H2O)(4)](2)[Co(mu-mell)(H2O)(2)].10H(2)O}(n), 1, were synthesized by slow evaporation method at room temperature (bipy = 2,2 '-bipyridine, mell = hexaanion ...
Solubility in the ternary system CaSO4 + Na2SO4 + H2O at 298.15 K
(Maik Nauka/Interperiodica/Springer, New York, 2011)
The solubility in the ternary system, aqueous mixture of CaSO4 and Na2SO4, at T = 298.15 K comprises five different salts: calcium sulfate dihydrate, mirabilite, thenardite, glauberite and labile salt. Using the Extended ...
Selective removal of heavy metals from metal-bearing wastewater in a cascade line reactor
(Ecomed Publishers, Landsberg, 2007)
Goal, Scope and Background. This paper is a part of the research work on 'Integrated treatment of industrial wastes towards prevention of regional water resources contamination INTREAT' the project. It addresses the ...
Hydrometallurgical process for extraction of metals from electronic waste, Part I: Material characterization and process option selection
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Used electronic equipment became one of the fastest growing waste streams in the world. In the past two decades recycling of printed circuit boards (PCBs) has been based on pyrometallurgy, highly polluting recycling ...
