Polyamidoamine as a clay modifier and curing agent in preparation of epoxy nanocomposites
(Elsevier Science Sa, Lausanne, 2019)
In the present study the commercial multifunctional fatty acid polyamidoamine (PAA) was for the first time simultaneously applied as a curing agent and clay modifier for epoxy/clay nanocomposites (NC) based on diglycidyl ...
Molecular and Supra-Molecular Structural Ordering of Wheat Starch-OSA Modified Waxy Maize Starch Mixtures During Storage
(Wiley-VCH Verlag Gmbh, Weinheim, 2019)
The influence of waxy maize OSA starches on the retrogradation kinetics of wheat starch pastes is investigated using dynamic oscillatory rheological and differential scanning calorimetry (DSC) measurements. Total starch ...
Selection of the suitable polymer for supercritical fluid assisted preparation of carvedilol solid dispersions
(Elsevier Science Bv, Amsterdam, 2019)
Solid dispersions production is one of the substantial approaches for improvement of poor drug solubility. Additionally, supercritical fluid assisted method for preparation of solid dispersions can offer many advantages ...
The initial characteristics of the polypyrrole based aqueous rechargeable batteries with supercapattery characteristics
(Elsevier Science Bv, Amsterdam, 2019)
The electrochemically synthesized polypyrrole (PPy) is investigated as a possible active material of the low-cost aqueous based secondary power sources in combination with zinc, lead oxide, and lead sulfate. The discharge ...
Advantages of Microreactor Technology over Conventional Methods in Enzymatic Wastewater Treatment – Environmental Application of Enzymes
(Belgrade : Association of Chemists and Chemical Engineers of Serbia UHTS, 2019)
Wastewater treatment is one of the most analysed issue in theory and practice because
of its current and vast significance nowadays. Wide range of chemical, physical and
biochemical processes are developed for wastewater ...
Theorems of the Alternative for Systems of Convex Inequalities
(Springer, Dordrecht, 2019)
Systems of convex inequalities in function spaces are considered. Solvability conditions are obtained in the form of a theorem of the alternative. We revisit some results from the literature where such theorems are incorrect. ...
Antibacterial ability of immobilized silver nanoparticles in agar-agar films co-doped with magnesium ions
(Elsevier Sci Ltd, Oxford, 2019)
The antibacterial ability of in situ prepared nanometer-sized silver particles, immobilized in agar-agar films, was studied as a function of the concentration of co-dopant, magnesium ions. Content of inorganic components ...
Hydrothermal synthesis of hematite (α-Fe2O3) nanoparticle forms: Synthesis conditions, structure, particle shape analysis, cytotoxicity and magnetic properties
(Journal of Alloys and Compounds, 2019)
In this work, we present the magnetic and structural properties of α-Fe 2 O 3 nanoparticles synthesized by the hydrothermal synthesis method. XRD, FTIR and Raman spectroscopy indicate that the samples consist of single-phase ...
Synthesis and thermal properties of arylazo pyridone dyes
(Elsevier Sci Ltd, Oxford, 2019)
Thermal degradation properties of 5-(4-substitutedphenylazo)-3-amido-6-hydroxy-4-methy1-2-pyridones and 5-(4-substitutedphenylazo)-3-cyano-6-hydroxy-4-methy1-2-pyridones dyes, differing in electron withdrawing and electron ...
Biodiesel synthesis over green catalyst: The effect of thermal treatment of CaO/Zeolite precursor on catalytic activity
(Belgrade : Serbian Chemical Society, 2019)
The green CaO/Zeolite catalyst for methanolysis of fatty oils was synthesized entirely from the waste materials. CaO derived from chicken eggshell was loaded onto fly ashbased zeolite catalyst carrier by the wet impregnation ...
