Molecular Interaction Studies In Binary Mixtures Containing Aniline, Toluene And N-Butanol, Palaniappan Lakshmanan, Mahendran Govindasamy
Turkish Journal of Physics
Ultrasonic velocity and density values have been measured at 303 K in binary mixtures containing aniline, toluene and n-butanol; and the thermodynamical approach is applied to evaluate the mixtures' molar volume, adiabatic compressibility, intermolecular free length and excess values. The observed results are interpreted in terms of molecular interaction between the components of the mixtures. Observed excess values and their fittings of R-K type equations lend further support to the observation made in the binary system.

This work demonstrates the potential of three-dimensional biometric quantification using microtomography on larger benthic foraminifera. We compare traditional linear and area measures used for calculating three-dimensional characters with actual 3D measurements made from volume images obtained using X-ray microtomography (microCT). Two specimens of recent larger benthic foraminifera, i.e., Palaeonummulites venosus and Operculina ammonoides, were imaged with a high-resolution microCT scanner. This method enables three-dimensional imaging and calculation of measurements like 3D distances, surfaces and volumes. The quantitative high-resolution images enabled the extraction of the lumina from the proloculus to the last complete scanned chamber and of the canal system spreading …
