Interplay between steps and nonequilibrium effects in surface diffusion for a lattice-gas model of O/W (110
The authors consider the influence and nonequilibrium conditions on surface diffusion in a strongly interacting surface adsorbate system. The collective diffusion then depends on two competing factors: domain growth within the o...

Self-diffusion in a lamellar and gyroid (ordered) diblock copolymer investigated using pulsed field gradient NMR.
We report about self-diffusion experiments on a compositionally asymmetric poly(ethylene-co-propylene)-block-poly(dimethylsiloxane) diblock copolymer exhibiting the lamellar and the gyroid morphology. The most probable self-diffusion

Optimal error estimates for nonstationary singularly perturbed problems for low discretization orders
Nonstationary 1D singularly perturbed convection-diffusion equation is discretized in space by the finite element method on a Shishkin mesh and by time discontinuous Galerkin method. The resulting scheme is analyzed and diffusion-un...
