Glass-forming liquids are broadly classified as being fragile or strong, depending on the deviation from Arrhenius behavior of their relaxation times. A to strong crossover is observed inferred in like water and silica, more recently also metallic glasses phase change alloys, leading expectation that such a widely realised among glass formers. We investigate computationally well-studied Kob-And...

We consider the liquid-gas phase boundary in a binary fluid mixture near its critical end point. Using general scaling arguments we show that the diameter of the liquid-gas coexistence curve exhibits singular behaviour as the critical end point is approached. This prediction is tested by means of extensive Monte-Carlo simulations of a symmetrical Lennard-Jones binary mixture within the grand ca...

The Marangoni contraction of sessile drops of a binary mixture of a volatile and a nonvolatile liquid has been investigated experimentally and theoretically. The origin of the contraction is the locally inhomogeneous evaporation rate of sessile drops. This leads to surface tension gradients and thus to a Marangoni flow. Simulations show that the interplay of Marangoni flow, capillary flow, diff...

The ultrasonic velocities in binary liquid mixtures of carbon tetrachloride with benzene, toluene, m-xylene, ethyl benzene and chloro benzene have been measured at entire mole fraction range at 303.15K, using ultrasonic interferometer of frequency 2 MHz. Isentropic compressibilities KS, deviations of KS from ideal mole fraction mixture law ΔKS, available volumes Va, Lennard Jones potential repu...

a simple and reliable method for quick estimation of the dielectric constant of a binary solvent mixture is proposed. the validity of the proposed method has been tested for a broad range of binary solvent mixtures
