Systematical experimental data on density, molar volume and the surface tension, measured in electromagnetic levitation, has been summarized for liquid Ti-V system. The optical dilatometry method as well oscillating drop technique have employed to investigate temperature- compositional dependence. A linear decrease density tension with increasing temperature observed all investigated compositio...

Dielectric spectroscopy was carried out on the van der Waals liquid, 1,1(')-di(4-methoxy-5-methylphenyl)cyclohexane (BMMPC) in the supercooled state at pressures up to 218 MPa. The excess wing in this type-A glass former exhibits a response to pressure and temperature changes that is identical to that of the primary structural relaxation peak, indicating that the two processes reflect correlate...

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...

precise localization of the third molars in relation to the inferior alveolar nerve canal is critical from a clinical point of view and strongly affects the surgical treatment outcome. recently, by using three-dimensional modeling software, the relationship of third molar root apices and inferior alveolar nerve canal can be better understood. in this study, the spatial relationship of two surgi...

Densities of binary mixtures of 4,4’-dipentylazoxybenzene (DPAB) and 4-ethyl-4’-pentylazoxybenzene (EPAB) with 4-pentyl-4’-cyanobiphenyl (PCB) were measured over the temperature range of 25 to 80 °C and in the middle area of concentrations. Isothermal volumes of mixing Vs (equal to the excess volume VE when both pure components and solution are in the same phase) were also calculated from inter...

We have studied the composition dependence of density liquid water-DMSO mixtures at different temperatures by using isobaric-isothermal (NPT) molecular dynamics computer simulations. The non-polarizable semi-flexible, P1 and P2 models for DMSO molecule combined with TIP4P-2005 water model are considered. excess mixing volume apparent molar volumes species reported. established that P1-TIP4P-200...

Molar excess Volumes, Vijk and speeds of sound , uijk of 2-pyrrolidinone (i) + benzene or toluene (j) + ethanol (k) ternary mixture have been measured as a function of composition at 308.15 K. The observed speeds of sound data have been utilized to determine excess isentropic compressiblities, ( E S κ )ijk of ternary (i + j + k) mixtures. Molar excess volumes, Vijk and excess isentropic compres...

Hydrazine has been determined by its oxidation to nitrogen with a known excess of bromine. Bromine in acidic medium bleaches the dye methyl red. A known excess of bromine when treated with hydrazine is reduced to bromide and the unreacted bromine is determined using methyl red. The molar absorptivity is calculated to be 9.95 x10 L molcm. The method obeys Beer’s law in the range 0-6 μg of hydraz...

Hydroxylamine has been determined by its oxidation to nitrite with a known excess of bromine. Bromine in acidic medium bleaches the dye methyl red. A known excess of bromine when treated with hydroxylamine is reduced to bromide and the unreacted bromine is determined using methyl red. The method obeys Beer’s law in the range 0-5 μg of hydroxylamine in an overall aqueous volume of 25 mL. The rel...
