  • We calculate the effects of random density fluctuations on two-neutrino flavor transformations ({nu}{sub {tau}({mu}){parallel}}{nu}{sub {ital e}}) in the post-core-bounce supernova environment. In particular, we follow numerically the flavor evolution of neutrino states propagating through a stochastic field of density fluctuations. We examine the approach to neutrino flavor depolarization and study the effects of this phenomenon in both the early shock reheating epoch and the later {ital r}-process nucleosynthesis epoch. Our results suggest that significant fluctuation-induced neutrino flavor depolarization effects occur in these environments only when the zero-order (without density fluctuations) evolution of the neutrino states includes adiabatic propagation through resonancesmore » (mass level crossings). In the shock reheating epoch, depolarization effects from fluctuations with amplitudes larger than 0.05% of the local matter density can cause an increase in the heating rate of the material behind the shock compared to the case with no neutrino flavor transformation, but this corresponds to a significant decrease in this quantity relative to the case with adiabatic neutrino transformation. If {ital r}-process nucleosynthesis is to occur during the late stages of supernova evolution, then the requirement of neutron-rich conditions excludes a region of neutrino mass-squared difference and vacuum mixing angle ({delta}{ital m}{sup 2}, sin{sup 2}2{theta}) parameter space for neutrino flavor transformation. We find that in the presence of stochastic fluctuations, this excluded region is not significantly altered even for random fluctuations with an amplitude of 1% of the local matter density. {copyright} 1995 The American Physical Society.« less
  • On superhydrophobic surfaces, drops in theWenzel state can be switched to the suspended Cassie state in some cases, but in other cases are irreversibly impaled in the surface roughness. To date, the question of when dewetting transitions are possible for Wenzel drops has not been resolved. Here, we show that pinned Wenzel drops being stretched out-of-plane cannot reduce their contact angle below a critical value where unstable pinch-off occurs, preventing dewetting for Wenzel drops which exhibit receding contact angles beneath this critical pinchoff angle. Dewetting transitions are therefore only possible for Wenzel drops with moderately large receding contact angles, whichmore » requires low surface roughness for one-tier surfaces or a Partial Wenzel wetting state for two-tier surfaces.« less
  • The spreading of liquid Ag and Ag-Mo alloys on molybdenum substrates has been studied using a drop-transfer setup. Even though initial spreading velocities as fast as {approx}1 m/s have been recorded in some experiments, a large variation in the spreading dynamics has been observed, and there is no unique relationship between the contact angle and the spreading velocity. This can be attributed to the formation of ridges at the triple junction, the movement of which controls spreading. The fastest spreading rates are consistent with results reported for low temperature liquids; these can be described using a molecular-kinetic model. Spreading kineticsmore » and final contact angles were similar for pure silver and silver-molybdenum liquids.« less
  • The dynamics of dimethyldidodecylammonim bromide (DDAB) aqueous surfactant solutions spreading over a deep layer of liquid hydrocarbons is studied by video-enhanced microscopy at 23 C and at different relative humidities ranging from 35 to 100%. Aqueous DDAB droplets do not spread over simple liquid hydrocarbons until the DDAB concentration exceeds 0.005 wt % where the initial spreading coefficient is positive and the aqueous DDAB solutions consist of dispersed small vesicles and large liposome-like aggregates. The rates of spreading strongly depend on surfactant concentration, even though the initial spreading coefficient is essentially constant with concentration. Neither relative humidity nor drop volumemore » significantly influences spreading rates, although larger drop volumes do spread to larger areas. Classical tension-gradient-driven spreading theory, developed for pure, nonvolatile, and immiscible liquid spreading on a second liquid predicts lens expansion rates that are an order of magnitude higher than those experimentally observed for DDAB solutions. With the aqueous DDAB surfactant solutions, spreading eventually ceases in the form of equilibrium lenses whose areas increase linearly with both surfactant concentration and drop volume. A surprising and important observation is that substrate viscosity has only a minor effect on the rate of surfactant solution spreading. Fascinatingly, DDAB solution droplets actually spread faster on mineral oil than on dodecane, which is 18 times less visous, even though the initial spreading coefficients of these two substrates are essentially identical. The authors argue that the rate of surfactant arrival at the stretching air-water and oil/water interfaces determines the droplet spreading kinetics.« less
  • Spreading of aqueous drops on hydrocarbon liquids occurs only when particular surfactants are added to the droplets above a critical concentration. For surfactant solutions of didodecyl ammonium bromide (DDAB) in water spreading over mineral oil, rates of droplet expansion are much slower than those corresponding to pure liquids spreading over immiscible liquid substrates with the same initial spreading coefficients. The authors present a sorption-kinetic model to explain quantitatively the spreading histories for aqueous DDAB droplets on mineral oil. Due to surfactant transport limitations, spreading occurs only when enough surfactant arrives at the dilating lens surfaces to establish a slightly positive,more » but near-zero spreading coefficient. The authors solve the convective diffusion equation for a cylindrical disk-like lens under the integral constraint of a constant surfactant adsorption density corresponding to a near-zero spreading coefficient. All observed spreading behavior is correctly portrayed by the proposed sorption-kinetic model including final equilibrium lens formation and spreading rates that are sensibly independent of drop volume, but are strongly dependent on drop surfactant concentration. Quantitative agreement is found with the experimental spreading data for a surfactant diffusion coefficient of 6 x 10{sup {minus}12}m{sup 2}/s and an effective adsorption rate constant of 6.5 x 10{sup {minus}7} m/s. Both values prove physically reasonable. The sorption-kinetic model provides a new mechanism for understanding slow surfactant-driven spreading.« less
