“…They were partially degassed by passing nitrogen gas just prior to use. The purity of all the solvents was checked by comparing the experimental density, speed of sound, and refractive index data for pure liquids with the literature 19,20,[23][24][25][26][27][28][29][30][31] as listed in Table 1.…”

The experimental data of densities (F), speeds of sound (u), and refractive indices (n D ) of aqueous solutions of different glycol ethers, namely, ethylene glycol iso-propyl ether (EGIPE), ethylene glycol monobutyl ether (EGMBE), diethylene glycol dimethyl ether (DEGDME), diethylene glycol monobutyl ether (DEGMBE), propylene glycol monomethyl ether (PGMME), and dipropylene glycol monomethyl ether (DPGMME), over the entire composition range, at temperature T ) 298.15 K, and at one atmospheric pressure have been obtained. The derived parameters such as the apparent molar volume (φ V ) of solute, isentropic compressibility of solution (β S ), apparent molar isentropic compressibility (φ KS ) of solute, excess molar volume (V E ) of solution, molar refraction ([R] 1,2 ), deviation in refractive index (∆n D ) of solutions, deviation in molar refraction (∆[R] 1,2 ), and the deviation in isentropic compressibility (∆β S ) have been computed. The limiting apparent molar volumes of solutes (φ V 0 ), limiting apparent molar isentropic compressibilities of solutes (φ KS 0 ), and the limiting excess partial molar volumes of solutes (V j 2 0E) have also been obtained. The results are interpreted in terms of hydrogen bonding, solute-solute, and solute-solvent interactions.

“…In order to enhance the colloidal stability of SrTiO 3 dispersion also, 2-methoxyethanol and isopropanol were added, they have low dielectric constant, 17.41 for 2-methoxyethanol [26] and 18.62 for isopropanol, in contrast to 80.37 for water (all at 20°C) [27]. Therefore, these organic solvents increase the charge density of the electric double layer of particles, increasing the zeta potential [26]. Since SrTiO 3 is a ntype semiconductor, negative surface charge arises from its nature and also by the hydroxylation process, hence the Stern layer has composed by counter ions in relation to the surface charge, resulting in a greater amount of positive charges (+) around these particles.…”

Researches on solids heterojunctions has proven to be an important field for technological applications due to synergism achieved by interface phenomena. In this work, we present an understanding of SrTiO 3 /TiO 2 interface and its effects on structural and microstructural characteristics, and relate them to photoluminescence properties of heterojunctions obtained by a simple method. It was observed that SrTiO 3 proportion directly influences the structural order-disorder, as observed by X-Ray diffraction, Raman spectroscopy and Transmission electron microscopy. Photoluminescence behavior of heterojunction with 1% of SrTiO 3 showed a shift to blue emission region compared to TiO 2 , and enhanced of emission intensity compared to SrTiO 3 , resulted from defects generated by interface effects, attracting possible applications on selective color emitter. Therefore, we conclude that in same materials phases, nature and concentration of structural defects has strong dependence of SrTiO 3 concentration, which leads to different photoluminescence properties.

“…We have studied previously the nature and type of intermolecular interactions in binary liquid mixtures containing alkoxyalcohols or polyethylene glycols in terms of the mixing parameters such as excess molar volume, excess molar refractivity, deviations in relative permittivity, deviations in viscosity, and deviations in isentropic compressibility [1][2][3][4][5][6]. The 2-propoxyethanol (PE), diethylene glycol (DEG), triethylene glycol (TEG), and tetraethylene glycol (TET-RAEG) have been used in the present studies.…”
