In this work, Cerium Nickel nanocomposite was synthesized and investigated as photocatalyst. Co-precipitation method was used successfully to synthesize Ce-Ni oxides. Couple of characterization techniques such as XRD (powder X-ray Diffraction), FESEM (Field Emission Scanning Electron Microscope), UV-Vis spectroscopy, FTIR (Fourier Transform Infrared spectroscopy) were used to explore the structure, size and morphology of the synthesized photocatalyst. The nanocomposite particle size was average out to be approximately 25–30 nm. To evaluate the photocatalytic efficiency of Ce–Ni nanocomposite, Methylene blue (MB) dye, a model organic compound, was degraded under visible light. To estimate the dye degradation efficiency of nanocomposite, UV/Vis spectroscopy was used, and the results showed 87% Photodegradation of organic pollutant in 3 h. The results illustrate usefulness of Ce nanocomposite with nickel for photocatalytical degradation of organic pollutant under exposure of visible light.

Some of the most active academic and scientific research faces of the past decade are on ionic liquids and their behavior for industrial purposes. In the present work, the densities and sound velocities of an amino acid (glycine) in pharmaceutically active ionic liquid 1-Butyl-3-methylimidazolium hexafluorophosphate [BMIm][PF6] solutions were measured at different temperatures ranging from 293.15 K to 318.15 K under atmospheric pressure. The experimental data has been further used to calculate volumetric and acoustic parameters such as apparent molar volumes, VΦ and apparent molar isentropic compression, KΦ partial molar expansion, EΦ0 partial molar volume, VΦ0 and partial molar isentropic compression KΦ0 and corresponding empirical constants, Sv and Sk. The negative values are obtained for partial molar volume of transfer, ΔtVΦo at all temperatures and become more negative by increasing the concentration of the ionic liquid. The positive values of partial molar expansibilities, EΦo are decreasing with an increase in temperature predict increasing electrostriction. The obtained values of expansibilities show the structure-making/breaking ability of glycine in investigated solutions.

This work intended to enhance the unique and outstanding properties of lanthanum by synthesizing its nanocomposite. A lanthanum-based nanocomposite was prepared by a simple and cost-effective “co-precipitation” method. Lanthanum nitrate (La (NO3)3) and zinc nitrate (Zn (NO3)2) were used as precursors. The lanthanum/zinc oxide nano composite formed was then calcined at 450 °C for 4 h in order to obtain a fine powder with size in the nano range of 1–100 nm. Characterization of the prepared catalyst was done by ultraviolet/visible spectroscopy, Fourier transform infrared spectroscopy, and photoluminescence. Crystallinity and morphology were found by X-ray diffraction and scanning electron microscopy. The synthesized nanocomposite material was also tested for heterogeneous catalytic applications of 4-nitrophenol (4-NP) reduction into 4-aminophenol (4-AP). It was found to be successful in complete reduction of 4-NP with enhanced catalytic performance.

Removal of hazardous organic dyes from polluted water bodies requires the introduction of strong adsorbents and photocatalysts to industrial wastewaters. Herein, photocatalytic CeO2 nanoparticles and CeO2/CuO nanocomposite were synthesized following a co-precipitation method for low cost elution of methylene blue (MB) from water. The crystallinity and surface structure of the as-prepared materials have been analyzed using characterization techniques including X-ray powder diffraction (XRPD), field emission scanning electron microscopy (FE-SEM), energy-dispersive spectroscopy (EDS), ultra-violet visible spectroscopy (UV–Vis), and Fourier-transform infrared spectroscopy (FTIR). The average particle size of both the nano scaled samples were approximately 20–30 nm. The photocatalytic properties of CeO2/CuO were investigated under visible light against methylene blue (MB). The results showed 91% photodegradation of MB organic pollutant in 3 h as monitored by UV–Vis spectroscopy. Absorbance peaks appeared at around 670 nm corresponding to degradation of MB. Such output displayed the effectiveness of Ce nanocomposites for environmental benefits. Hence, CeO2/CuO nanocomposite could be useful for treatment of industrial wastewaters by removing hazardous MB dye.

Knowledge of drug interactions and the factors controlling these interactions could be useful to overcome their adverse effects on human health. In this study, the effect of caffeine on the antidepressant action of escitalopram oxalate was investigated to explore the behavior of escitalopram oxalate in the presence of caffeine in terms of molecular interactions in an aqueous system at temperature range 293.15 to 313.15 K and atmospheric pressure. Density (ρ) and ultrasonic velocity (u) of escitalopram oxalate in different concentrations of caffeine solutions were measured at the selected range of temperatures. Experimental data has been used to calculate apparent molar volume (Φv) and apparent molar isentropic compressibility (Φv) and fitted to the Redlich–Mayer equation to obtain limiting parameters. Negative deviations from Debye–Huckel limiting law of apparent molar volume for the drug in the presence of caffeine were observed which can be used as a direct measure of the ion-ion and ion–solvent interactions. Partial molar volumes of transfer (ΔtΦvο) were found to be negative for the studied mixture. The partial molar expansibilities and Hepler's constant (∂2∅V0/∂T2) were found to be positive for the mixture (escitalopram oxalate+ caffeine) in water. Intermolecular free length (Lf) and compressibility hydration number (nH) were also analyzed. Obtained results were explored in terms of molecular interactions prevailing among escitalopram oxalate and caffeine molecules in aqueous solutions.

Sweetness behavior of a carbohydrate namely maltose was studied in the presence of amino acids (L-alanine and L-arginine) in terms of volumetric and acoustic properties of their solutions. Density (ρ) and ultrasonic velocity (μ) of maltose in different concentrations of amino acids solutions were measured at temperatures 293.15 K, 303.15 K and 313.15 K. Calculated volumetric and acoustic parameters such as apparent molar compressibility, specific molar volume and expansibility factor etc. were explored in terms of molecular interactions present in carbohydrate-amino acid solutions. Obtained results of transfer volume of maltose from aqueous to amino acid systems indicated the presence of ion-ion, ion-polar and hydrophobic–hydrophobic interactions in solutions, which was also confirmed from obtained positive values of apparent molar volume and negative values of apparent molar isentropic compressibility. Calculated value of apparent specific volumes i.e. 0.618 cm3g−1 lies in the range of 0.51 cm3g−1 to 0.71cm3g−1 for sweetness response indicated the sweetness behavior of maltose in aqueous amino acids solutions.

Volumetric and acoustic studies of amino acids (l‑aspartic acid and l‑serine) in water and in aqueous cetyl trimethyl ammonium bromide (CTAB) solutions were carried out to understand intermolecular interactions in aqueous solutions of amino acids and in colloidal solutions containing cationic micelles. Density and sound velocity of amino acids solutions of different concentrations in water and in colloidal solutions of CTAB were measured at different temperatures (303.15 K–313.15 K). Volumetric and acoustic parameters like apparent and partial molar volume (Vφ and Vφo), expansibility factor (Eφo), transfer volume, compressibility factors (Kφ and Kφo) and intermolecular free length (Lf) were calculated using measured density and sound velocity data of amino acids solutions. Positive values of Vφ and negative values of Kφ are indicative of strong intermolecular electrostatic interactions among ions of amino acids and water molecules. Presence of CTAB molecules in micellar form in amino acids solutions causes an overall increase in degree of intermolecular interactions among components of solutions. Moreover, positive values of expansibility factor showed the structure making behavior of amino acids both in water and in aqueous CTAB solutions.

Volumetric and acoustic studies of l‑arginine in water and in aqueous sodium dodecyl sulphate (SDS) solutions were carried out to understand intermolecular interactions in solutions of arginine with water and colloidal solutions containing anionic micelles. Density and ultrasonic velocity data for arginine in water and in aqueous colloidal solutions were measured over a temperature range (288.15 K–308.15 K). The experimental data have been used to calculate apparent and partial molar volume (Φv, Φvο), apparent and partial molar compressibility (Φk, Φko), transfer volume (Φνto), partial molar expansibility (ΦE°), acoustic impedance (Z) and relative association (τ) etc. to comprehend inter and intra molecular interactions. The above mentioned parameters have been used to explore the arginine-surfactant interactions among ions of arginine and water molecules. The trends of transfer volumes have been interpreted by the cosphere overlap model. Moreover, expansibility factor showed the structure making behavior of arginine both in water and in aqueous SDS solutions.

Densities and sound velocities for aqueous monoethanolamine (MEA) system are reported over the entire composition range at different temperatures (298.15, 303.15, 313.15 and 318.15 K). These experimental data have been further used in calculating the excess molar volume, partial molar volumes, isobaric thermal expansion coefficients and the deviation in isentropic compressibility. The excess molar volumes data were fitted to the Redlich–Kister polynomial equation to obtain their coefficients and standard deviations. The partial molar volume at infinite dilution of both water in MEA and MEA in water and have been determined using two different methods. Knowledge of the above properties of these mixtures is a basis for understanding some of the molecular interactions in these systems. From the analysis of the results, the type of interactions between the MEA and water is discussed in terms of the number and size of the alkyl groups attached to the nitrogen atom of MEA.

Densities and ultrasonic velocity values for aqueous solutions of sodium saccharin (SS) has been measured as a function of concentration at 20.0-45.0 °C and atmospheric pressure using DSA-5000 M. The density and ultrasonic velocity values have been further used to calculate apparent molar volume, apparent specific volume, isentropic apparent molar compressibility and compressibility hydration numbers and reported. The values for apparent molar volume obtained at given temperatures showed negative deviations from Debye-Hückel limiting law and used as a direct measure of the ion-ion and ion-solvent interactions. The apparent specific volumes of the solute were calculated and it was found that these values of the investigated solutions lie on the borderline between the values reported for sweet substances. The sweetness response of the sweeteners is then explained in terms of their solution behaviours. Furthermore, the partial molar expansibility, its second derivative, (∂(2)V°/∂T(2)) as Hepler's constant and thermal expansion coefficient have been estimated.

The solution properties of d-Mannitol (DM) were studied to explore sweetness response and molecular interactions in aqueous solutions at different temperatures. The density (ρ) and ultrasonic velocity (μ) were measured at 20-45°C using density sound velocity metre (DSA 5000M). The results obtained were used to compute apparent and partial molar volume, apparent specific volumes, partial molar expansibility, apparent molar isentropic compressibility and compressibility hydration number. The partial molar volume (ΦV°) indicates hydrophilic interactions dominating in aqueous solution of DM. The quality of taste has been determined from apparent specific volumes (ASV) data at 20-45°C and 0.04-0.89 mol kg(-1).The apparent molar isentropic compressibility (ΦK(s)) and hydration number (nH) conferred pre-dominance of solute-solvent interactions, whereas partial molar expansibility (ΦE°) and related standards predicted structure making behaviour of DM. This study may provide new insights in elucidation of mechanistic differences between sweeteners and their mode of interactions.

Densities and ultrasonic velocity values for aqueous solutions of two sweeteners viz., maltose monohydrate and acesulfame-K have been measured as a function of concentration at 20.0-45.0°C and atmospheric pressure. Solutions of acesulfame-K were treated as electrolyte, while maltose was considered as non-electrolyte. The apparent molar and specific volumes, their isentropic apparent molar and specific compressibilities, as well as their compressibility hydration numbers have been calculated and reported. Negative deviations from Debye-Huckel limiting law of apparent molar volume for acesulfame-K was obtained at given temperatures and can be used as a direct measure of the ion-ion and ion-solvent interactions. Furthermore, apparent specific volumes of the solutes were calculated and it was found that these values of the investigated solutes lie on the borderline between the values reported for sweet substances. The partial molar expansibility, its second derivative values, (∂(2)V(0)/∂T(2)) and thermal expansion coefficient have been estimated.

Polyurethanes (PUs) prepolymers blended with bentonite nanoclay and without bentonite nanoclay were prepared by the reaction of toluene-2,4-diisocyanate (TDI) and hydroxyl terminated polybutadiene (HTPB), and the chain was further extended with 1,4-butane diol (1,4-BDO) to get final polyurethane nanocomposites (PUNC). A mixture of polymer and bentonite clay enriched in montmorillonite (MMT) was formed in solution polymerization, in which MMT dispersed depending on interaction of MMT with polymer chains. The molecular structure of the monomers and the prepared PU nanocomposites was confirmed by FTIR. A series of PUNCs were prepared by varying the percent compositions of bentonite nanoclay into the PU matrix. The existence of the clay in to the PU was confirmed by scanning electron microscope (SEM). SEM images verified the good dispersion of the bentonite nanoclay in PU matrix.

A series of amino silicone based softeners with different emulsifiers were prepared and adsorbed onto the surfaces of cotton and blends of cotton/polyester fabrics. Factors affecting the performance properties of the finished substrate such as post-treatment with amino functional silicone based softener varying different emulsifiers in their formulations and its concentration on different processed fabrics were studied. Fixation of the amino-functional silicone softener onto/or within the cellulose structure is accompanied by the formation of semi-inter-penetrated network structure thereby enhancing both the extent of crosslinking and networking as well as providing very high softness. The results of the experiments indicate that the amino silicone can form a hydrophobic film on both cotton and blends of cotton/polyester fabrics and its coating reduces the surface roughness significantly. Furthermore, the roughness becomes lesser with an increase in the applied strength of amino silicone based softener.
