Developing novel hydrocarbon-based proton exchange membranes is at the Frontier of research on fuel cells, batteries and electrolysis, aiming to reach demand for advanced performance in conductivity, retardation, swelling, mechanical thermal stability <italic>etc.</italic>
We present the Moving Eulerian-Lagrangian Particles (MELP), a novel mesh-free method for simulating incompressible fluid on thin films and foams. Employing bi-layer particle structure, MELP jointly simulates detailed, vigorous flow large surface deformation at high stability efficiency. In addition, we design multi-MELP: mechanism that facilitates physically-based interaction between multiple systems, to simulate bubble clusters foams with non-manifold topological evolution. showcase...
We propose a particle-based method to simulate thin-film fluid that jointly facilitates aggressive surface deformation and vigorous tangential flows. build our dynamics model from the tension driven Navier-Stokes equation with dimensionality reduced using asymptotic lubrication theory customize set of differential operators based on weakly compressible Smoothed Particle Hydrodynamics (SPH) for evolving pointset surfaces. The key insight is nature SPH, which unfavorable in its typical usage,...
A clear description of the conformational and dynamical evolution polymer chains in shear flow is fundamental basis microfluidic separations macroscopic rheological behaviors. We employ graph theory analysis to analyze local deformation dynamics linear with different rigidities based on simulation trajectories that record instantaneous conformations dynamics. Our results show all semiflexible experience quasi-periodic tumbling motions when strain overwhelms U-shape (or S-shape) energy...
Water in polymer matrixes is likely to show anomalous dynamics, a problem that has not been well understood yet. Here, we performed atomistic molecular dynamics simulations study the water polyamide (PA) matrix, bulk phase of well-known reverse osmosis membranes. For time-dependent ensemble average, molecules experienced ballistic diffusion at shorter time scale, followed by crossover from subdiffusion Brownian scale ∼10 ns, and non-Gaussian diffusion, an indication sticks on even region....
We use Langevin dynamics to study the deformations of linear and ring polymers in different confinements by applying compression stretching forces on their two sides. Our results show that are an interplay among polymer rigidity, degree confinement, force applied. When applied is beyond threshold required for buckling transition, semiflexible chain under strong confinement firstly buckles; then comes helical deformation. However, same loading, weaker exhibits instability shrinks from folded...
