The density (d), speed of sound (u) and electrolytic conductivity (Λ) for systems containing acetaminophen, ionic liquid {1-octyl-3-methyl imidazolium bromide, [OMIm] Br} and water have been measured at T = 293.15-308.15 K. The measured data have been applied to calculate, standard partial molar volume ( ), Hepler’s constant , apparent molar isentropic compressibility...
The present work reported density, viscosity, speed of sound, electrical conductivity and refractive index data of L-alanine in the aqueous solutions of 1-hexyl-3-methylimidazolium ibuprofenate at T= 298.15 K. Using the measured data, partial molar volume of transfer ( ), partial molar isentropic compressibility of transfer ( ), viscosity B-coefficient of transfer (∆traB), ion association const...
The present paper reports the study of binary mixtures and their properties over the entire range of composition at temperatures 288, 298, 308 and 318 K. Excess dielectric constant, excess molar volume, excess refractive index, molar refraction and excess molar refraction at different temperatures have been computed from the experimentally measured values of the aforesaid parameters and fitted ...
Abstract Bi–Cu alloys may potentially be used for thermal energy storage or as a catalyst methane pyrolysis. For application research and simulations, it is necessary to know the reliable thermophysical properties of liquid alloys. Density (25, 50, 75 at. pct Cu) was measured with dilatometric method over 971 K 1500 range. decreases linearly temperature all compositions. The molar volume calcul...
The thickness of dental enamel is often discussed in paleoanthropological literature, particularly with regard to differences in growth, health, and diet between Neandertals and modern humans. Paleoanthropologists employ enamel thickness in paleodietary and taxonomic studies regarding earlier hominins, but variation in enamel thickness within the genus Homo has not been thoroughly explored desp...
