Evaporating drops of alkane mixtures
Alkane mixtures are model systems where the influence of surface tension gradients during the spreading and the evaporation of wetting drops can be easily studied. The surface tension gradients are mainly induced by concentration gradients, mass diffusion being a stabilising process. Depending on the relative concentration of the mixture, a rich pattern of behaviours is obtained. keywords Movin...
متن کاملSurfactant-induced Marangoni eddies alter the coffee-rings of evaporating colloidal drops.
The influence of the small ionic surfactant sodium dodecyl sulfate (SDS) on the evaporation of drying colloidal droplets is quantitatively investigated. The addition of SDS leads to a significantly more uniform deposition of colloidal particles after evaporation (i.e., the so-called "coffee-ring effect" is dramatically altered). We understand this phenomenon in the context of circulating radial...
متن کاملRush Hour is PSPACE-complete
In this report we give a formal definition of the sliding block puzzle Rush Hour and we report on the proof showing that Rush Hour is PSPACE-complete from “The nondeterministic constraint logic model of computation: Reductions and applications” by Hearn and Demaine (Proceedings ICALP 2002).
متن کاملICTs in the Rush Hour of Life
In the Netherlands, many women have entered the labor market in the last two decades. This development—among other social changes—has resulted in substantial shifts in the time that Dutch people spend on paid labor and “caring tasks” on the one hand and leisure activities on the other hand. This task combination has caused serious time pressure and coordination problems among dual-income famili...
متن کاملRescaling the dynamics of evaporating drops.
The dynamics of evaporation of wetting droplets is investigated experimentally in an extended range of drop sizes to provide trends relevant for a theoretical analysis. A model is proposed, which generalizes Tanner's law in the presence of evaporation. A qualitative agreement is obtained, which represents a first step toward the solution of a very old, complex problem.
