Viscosity of glass-forming liquids.
The low-temperature dynamics of ultraviscous liquids hold the key to understanding the nature of glass transition and relaxation phenomena, including the potential existence of an ideal thermodynamic glass transition. Unfortunately, existing viscosity models, such as the Vogel-Fulcher-Tammann (VFT) and Avramov-Milchev (AM) equations, exhibit systematic error when extrapolating to low temperatur...
متن کاملComputing the viscosity of supercooled liquids.
We describe an atomistic method for computing the viscosity of highly viscous liquids based on activated state kinetics. A basin-filling algorithm allowing the system to climb out of deep energy minima through a series of activation and relaxation is proposed and first benchmarked on the problem of adatom diffusion on a metal surface. It is then used to generate transition state pathway traject...
متن کاملCoalescence in low-viscosity liquids.
The expected universal dynamics associated with the initial stage of droplet coalescence are difficult to study visually due to the rapid motion of the liquid and the awkward viewing geometry. Here we employ an electrical method to study the coalescence of two low-viscosity droplets at early times. We measure the growth dynamics of the bridge connecting the two droplets and observe a new asympt...

متن کاملThe Accuracy of Measurements of Viscosity of Liquids
Most abso lut e meas urements of viscos ity have utili zed ca pi ll a ry fl ow, and required ~" 'TIl e mpir i ca l corrections amou nting to several times th eir precis ion and esti ma ted acc uracy . The range of va lu es found from these measure ments and the poss ibility of unrecognized syste ma tic e rrors make it impos' s ib le to base a realist ic estimate of accuracy on the results of on...
