Bifunctional (Zn,Fe)3O4 nanoparticles: Tuning their efficiency for potential application in reagentless glucose biosensors and magnetic hyperthermia
(Elsevier, 2019)
In a new approach based on a two-step procedure, co-precipitation method followed by hydrothermal treatment in a microwave field, Zn-substituted Fe3O4 nanoparticles (ZnxFe3-xO4) were synthesized. Results of XRD, FT–IR and ...
Study of Simultaneous Radionuclide Sorption by Mixture Design Methodology
(American Chemical Society (ACS), 2015)
The problem of simultaneous removal of Co2+, Sr2+, and Cs+ ions from aqueous solutions was addressed using oxide, phosphate, and aluminosilicate materials from economical and abundant sources. Competition between cations ...
Investigation of Mechanism and Critical Parameters for Removal of Arsenic from Water using Zr-TiO2 Composite
(Taylor & Francis, 2017)
Using microwave-hydrothermal method for synthesis of composite, high surface density of hydroxyl groups, as an active adsorption sites for arsenic, was obtained. Adsorption mechanisms of As(III) and As(V) onto zirconium ...
Synthesis, X-ray structure and DFT calculation of magnetic properties of binuclear Ni(II) complex with tridentate hydrazone-based ligand / Синтеза, кристална структура и прорачуни функционала густине магнетних својстава бинуклеарног комплекса Ni(II) са тридентатним хидразонским лигандом

What is the nature of bonding in [Fe(CO)3(NO)]− and [Fe(CO)4]2−?
(Springer Nature, 2020)
To shed new light on the electronic structure of [Fe(CO)3(NO)]¯ complex ion, DFT-based analysis of the nature of chemical bonding has been performed. For this purpose, the extended transition state energy decomposition ...
Preparation, characterization and photocatalytic activity of lanthanum and vanadium co-doped mesoporous TiO2 for azo-dye degradation
(Elsevier, 2013)
Titanium dioxide photocatalysts co-doped with lanthanum and vanadium were prepared by a facile microwave-assisted hydrothermal method and characterized by XRD, SEM, N-2 physisorption at 77 K and DRS. The characterization ...
Estimation of Lipophilicity of Some Polyoxygenated Steroids by the Means of Normal-Phase Thin-Layer Chromatography
(Taylor & Francis Inc, Philadelphia, 2015)
Unmodified silica gel in combination with two mobile phases, acetone-n-hexane and acetonitrile-dichloromethane, was used in order to evaluate the capability of normal-phase (NP) chromatography on bare silica gel in estimation ...
Towards understanding intermolecular interactions in hydantoin derivatives: the case of cycloalkane-5-spirohydantoins tethered with a halogenated benzyl moiety
(Royal Soc Chemistry, Cambridge, 2017)
A series of cycloalkane-5-spirohydantoins bearing a halogeno substituted benzyl group (X = Cl and Br) in position 3 has been synthesized and their structures (1-6) have been determined by a single crystal X-ray diffraction ...
Visible light absorption of surface-modified Al2O3 powders: A comparative DFT and experimental study
(Elsevier, 2019)
Surface modification of Al2O3 powders, prepared using reproducible sol-gel synthetic route with small colorless organic molecules, induces charge transfer complex formation and the appearance of absorption in the visible ...
Substituent Effects on the Patterns of Intermolecular Interactions of 3-Alkyl and 3-Cycloalkyl Derivatives of Phenytoin: A Crystallographic and Quantum-Chemical Study
(American Chemical Society (ACS), 2019)
