WebbThe primary application for this work is to model the spin coating of the interior of two-piece metal beverage cans, and we consider this problem in some depth. Specifically, we show how adjusting several parameters can eliminate one possible defect in the spin coating process: the tendency for droplets to detach from the substrate when the can is …

WebbWe study the problem ofsurfacedirected spinodal decomposition, viz., the dynamical interplay of wetting and phase separation at surfaces. In particular, we focus on the kinetics of wetting-layer growth in a semi-infinite geometry for arbitrary surface potentials and mixture compositions. We also present representative results for phase separation in …

WebbDrop Casting. This method is used for the formation of small coatings on small surfaces. It requires a very small amount of solvent. Multiple droplets formed using this method provide a distinctive environment to control the shrinkage direction and the evaporation rate of the droplets (Liu et al., 2014). In this method, solution is poured onto ...
