Densities , viscosities and ultrasonic velocities has been measured for the ternary mixture involving morpholine(1) + cyclohexanone(2) + 1hexanol(3) at 308.15K and 318.15K over the entire range of mole fraction. Parameters like excess volume, adiabatic compressibility, free volume, linear free energy, acoustic impedance, relative association and isentropic compressibility were calculated. From ...

We analyze the stability of small bubbles in a closed system with fixed volume, temperature, and number of molecules. We show that there exists a minimum stable size of a bubble. Thus there exists a range of densities where no stable bubbles are allowed and the system has a homogeneous density which is lower than the coexistence density of the liquid. This becomes possible due to the finite liq...

this article describes an accurate subpico flowmeter bifurcatedin to liquid and gas flowrates less than 1mol/s for both mems/nems and cryogenic technology applications. the mems/nems are described as either two gauges (instrument), or quartz fluctuating forks, even if the liquid or gas flows through an element, as well as cryogenic technology consisting of arrays of either parallel photonic cry...

First-principles molecular dynamics simulations at constant pressure have been used to investigate the mechanisms of compression of liquid SiO2. Liquid SiO2 is found to become denser than quartz at a pressure of about 6 GPa, in agreement with extrapolations of lower pressure experimental data. The high compressibility of the liquid is traced to medium-range changes in the topology of the atomic...

We report extensive simulation studies of phase behavior in single component systems of particles interacting via a core-softened interparticle potential. Two recently proposed examples of such potentials are considered; one in which the hard core exhibits a shoulder [Sadr-Lahijany et al., Phys. Rev. Lett. 81, 4895 (1998)], and the other in which the softening takes the form of a linear ramp [J...

We study the liquid anomalies arising from the Stell-Hemmer interaction, using molecular dynamics simulations and approximate 2D solutions. We observe in the liquid phase three types of anomalies: (i) An increase in specific volume upon cooling, (ii) an increase in isothermal compressibility upon cooling, and (iii) an increase in the diffusion coefficient with pressure. We relate the anomalies ...
