Free energies of steps on (111) fcc surfacesFor a hexagonal two-dimensional lattice we derive, using a surprisingly simple route, exact expressions for the step free energies along the high symmetry directions, left angle bracket1–10right-pointing angle bracket and left angle bracket11–2right-pointing angle bracket....
Shear dispersion and residence time for laminar flow in capillary tubes... An approximate theoretical solution for point sources in high-Péclet-number flows reveals that the mean residence time [left angle bracket]t(z)[right angle bracket], which is asymptotic to z/V0 near the source, will then rise faster than z/V0 before converging to z/V for large z, provided the source...
Pressure-driven flow of suspensions: simulation and theory... The time for achieving steady state scales as (H/a)3a/[left angle bracket]u[right angle bracket], where H is the channel width, a the radii of the particles, and [left angle bracket]u[right angle bracket] the average suspension velocity...
