Kinetics of Chalcopyrite Leaching by Hydrogen Peroxide in Sulfuric Acid
(MDPI, Basel, 2019)
In ores, chalcopyrite is usually associated with other sulfide minerals, such as sphalerite, galena, and pyrite, in a dispersed form, with complex mineralogical structures. Concentrates obtained by flotation of such ores ...
Hybrid material based on subgleba of mosaic puffball mushroom (Handkea utriformis) as an adsorbent for heavy metal removal from aqueous solutions
(Journal of Environmental Management, 2021)
The alkali treated subglebal tissue of the mosaic puffball (Handkea utriformis) (Sa) and Sa modified with hydroxyapatite (Sa-HAp), obtained by successive ionic layer adsorption and reaction (SILAR) method, were used for ...
Volumetric properties of binary mixtures of tetrahydrofuran, dimethyl adipate, 1-butanol and 2-butanol from (288.15 to 323.15) K and modeling by Prigogine-Flory-Patterson (PFP) and Extended Real Association Solution (ERAS) models
(Journal of Molecular Liquids, 2021)
In this work, experimental densities data of the binary system tetrahydrofuran + 2-butanol have been determined at eight temperatures, T=(288.15-323.15) K and atmospheric pressure and used for excess molar volume calculations. ...
High pressure densities and derived thermodynamic properties of deep eutectic solvents with menthol and saturated fatty acids
(Journal of Chemical Thermodynamics, 2021)
Densities of four Deep Eutectic Solvents (DESs) based on menthol and organic acids (menthol:octanoic acid (1:1), menthol:decanoic acid (1:1), menthol:dodecanoic acid (2:1) and decanoic acid:octanoic acid (1:3)) were measured ...
Synthesis of nano-crystalline NiFe2O4 powders in subcritical and supercritical ethanol
(Elsevier Science Bv, Amsterdam, 2016)
Nano-crystalline nickel ferrite has a broad range of applications due to its favourable magnetic properties. Those characteristics can be significantly influenced by the synthesis pathway including methods conducted in the ...
Volumetric and Viscometric Study of 1-Hexanol-Based Binary Systems: Experimental Determination and Modeling
(Amer Chemical Soc, Washington, 2020)
Density, viscosity, and refractive index of four binary mixtures with 1-hexanol are experimentally determined at seven temperatures, in the temperature range from 288.15 to 318.15 K and at atmospheric pressure. The choice ...
Intermolecular interactions of cis-3-hexes-1-ol or 1-hexanol with n-hexane: Thermodynamic study, FT-IR analysis and quantum chemical calculations
(Elsevier, Amsterdam, 2020)
Thermodynamic properties (density, viscosity, refractive index and speed of sound) of pure substances cis-3-hexen-1-ol, 1-hexanol and n-hexane and their binary systems cis-3-hexen-1-ol + n-hexane and 1-hexanol + n-hexane ...
Selenate adsorption from water using the hydrous iron oxide-impregnated hybrid polymer
(MDPI, Basel, 2020)
Hybrid adsorbent, based on the cross-linked copolymer impregnated with hydrous iron oxide, was applied for the first time for Se(VI) adsorption from water. The influence of the initial solution pH, selenate concentration ...
Multilevel split of high-dimensional water quality data using artificial neural networks for the prediction of dissolved oxygen in the Danube River
(Springer London Ltd, London, 2020)
In this study, a self-organizing network-based monitoring location similarity index (LSI) was coupled with Ward neural networks (WNNs) with the aim to create a more accurate, but less complex, multiple sites model for the ...
3D Printed Buccal Films for Prolonged-Release of Propranolol Hydrochloride: Development, Characterization and Bioavailability Prediction
(Pharmaceutics, 2021)
Gelatin-polyvinylpyrrolidone (PVP) and gelatin-poly(vinyl alcohol) (PVA) mucoadhesive buccal films loaded with propranolol hydrochloride (PRH) were prepared by semi-solid extrusion 3D printing. The aim of this study was ...
