Synthesis, structure and solvatochromic properties of some novel 5-arylazo-6-hydroxy-4-(4-methoxyphenyl)-3-cyano-2-pyridone dyes: Hydrazone-azo tautomeric analysis
(Elsevier Science Bv, Amsterdam, 2015)
A series of eleven new 5-arylazo-6-hydroxy-4-(4-methoxyphenyl)-3-cyano-2-pyridone dyes was synthesized and their absorption spectra were recorded in twenty solvents in the range 300-600 nm. Different solvent parameters, ...
Amides as a model system of low molar mass algal organic matter. Influence on the adsorption of p-nitrophenol on activated carbon
(Elsevier, Amsterdam, 2020)
In this study, the adsorption equilibrium and diffusivity parameters of p-nitrophenol were estimated for water containing different concentrations of secondary amides. Commercial powdered activated carbon was used as an ...
Solvatochromism and azo-hydrazo tautomerism of novel arylazo pyridone dyes: Experimental and quantum chemical study
(Elsevier, Amsterdam, 2019)
The state of the tautomeric equilibria of eleven arylazo pyridone dyes was evaluated from UV-Vis absorption spectra with the aid of the quantum mechanical modeling. NMR analysis and theoretical calculations, by using ...
Solutions of ionic liquids with diverse aliphatic and aromatic solutes - Phase behavior and potentials for applications: A review article
(Elsevier, Amsterdam, 2019)
This article principally reviews our research related to liquid-liquid and solid-liquid phase behavior of imidazolium- and phosphonium-based ionic liquids, mainly having bistriflamide ([NTf2](-)) or triflate ([OTf](-)) ...
Recovery of molybdenum oxyanions using macroporous copolymer grafted with diethylenetriamine
(Elsevier, Amsterdam, 2019)
The presented study describes macroporous crosslinked poly(glycidyl methacrylateco-ethylene glycol dimethacrylate) [PGME] functionalized with diethylenetriamine [PGME-deta] as a potential recovery agent for Mo(VI) oxyanions ...
A detailed experimental and computational study of monocarbohydrazones
(Elsevier, Amsterdam, 2020)
The substituent and solvent effect on intramolecular charge transfer (ICT) of twelve monocarbohydrazones (mCHs) were studied using experimental and theoretical methodology. The effects of specific and non-specific ...
Conformational stability of 5-substituted orotic acid derivatives analyzed by measuring C-13 NMR chemical shifts and applying linear free energy relationships
(Elsevier, Amsterdam, 2019)
Conformational stability of various 5-substituted orotic acid derivatives was studied by applying linear free energy relationships (LFER) to the C-13 NMR chemical shifts. The correlation analysis for the substituent-induced ...
Effects of different mechanical treatments on structural changes of lignocellulosic waste biomass and subsequent Cu(II) removal kinetics
(Elsevier, Amsterdam, 2019)
In this paper, the character of structural changes induced by different mechanical treatments to Prunus persica stones (PSs), and its subsequent effect on biosorption kinetics of Cu(II) were investigated. PSs were processed ...
N-(substituted phenyl)-2-chloroacetamides: LSER and LFER study
(Elsevier, Amsterdam, 2019)
The UV absorption spectra of twelve N-(substituted phenyl)-2-chloroacetamides were recorded in eighteen solvents. The effect of specific and non-specific solvent-solute interactions on the absorption maxima shifts was ...
Catena-[bis(o-aminobenzoato-kappa(3) N,O:O)Mn(II)]
(Elsevier Science Bv, Amsterdam, 2019)
In the title complex, [C14H12MnN2O4], the Mn(II) cation octahedrally coordinated by two N and two 0 atoms from two o-aminobenzoate ligands and two O atoms from another two o-aminobenzoate ligands. The carboxylate groups ...
