Background: The synthesis of Fe2O3/ZnO nanocomposites has gained wide acceptance in recent years due to its magnetic, photoluminescence and catalytic properties, and as an active element in gas sensors. This type of composite particle has potential biological and biomedical applications such as the detection of cancer cells, bacteria and viruses, and for magnetic separation. Objective: In the present study, first we synthes Read More

Objective: Mechanistic investigation of the reaction between the complex ion [FeIII2(μ-O)(phen)4(H2O)2]4+ (1) (phen = 1,10-phenanthroline) and its hydrolytic derivatives [FeIII2(μ-O)(phen)4(H2O)(OH)]3+ (1a) and [FeIII2(μ-O)(phen)4(OH)2]2+ (1b) which coexist in rapid equilibria in the range pH = 3.00 to pH = 5.00 (pKa1 = 3.71 ± 0.03, pKa2 = 5.28 ± 0.07) with N2H5+ ion to produce [Fe(phen)3]2+ has been covered in this st Read More

Introduction: Based on the dimensional analysis, ρ -u- thermodynamic and ρ -uoptical properties correlations have been applied to sixteen ionic liquids at different temperatures. The objective of the present work is to employ these relations to ionic liquids. The experimental values of ρ and u have been reported in the literature at different temperatures. We have computed thermal expansivity (α), isothermal compressibility (β Read More

A statistical study between ‘Mesophase Lower Transition Temperatures’ (MLTTs) and their structural properties is carried out to understand the effect of structural behaviour on mesomorphic property. Introduction: To establish a “Quantitative Structure and Property Relationship (QSPR) model” a set of randomly selected thirty-nine mesomorphic compounds is constructed. The backward stepwise regression analysis met Read More

Introduction: In this reported work, we have used 80 % aqueous dimethyl sulphoxide (DMSO) for density and viscosity measurement of pyrimidine-5-carbonitrile at 298.15 K. The obtained experimental results show that as concentration increases density and viscosity increases. From the results of density and viscosity, we have found apparent molar volume, limiting apparent molar volume, semi-empirical parameters, Falkenhag Read More

Background: The binary mixtures of isopropanol/isobutanol/isoamyl alcohol with an equimolar mixture of ethanol and formamide consist of different ultrasonic properties, which have been studied at room temperature at a fixed frequency of 2 MHz. The ultrasonic-related physical parameters like velocity (U), density (ρ), adiabatic compressibility (βad), intermolecular free length (Lf), acoustic impedance (Z), etc., ha Read More

Background: Visual pH sensors have received significant attention in the fields of environmental monitoring, analytical chemistry, food safety, and biomedicine. Therefore, a single organic moiety showing both naked-eye and fluorescence sensing of pH change is rare and in higher demand. Objective: A novel phenothiazine-based Schiff base PTz-SB was synthesized via facile organic transformations. This molecule showed pro Read More
