Modeling water uptake in a cereal grain during soaking
(Elsevier, 2010-03)
A diffusion equation to describe the isothermal absorption of liquid water in a spherical solid that undergoes uniform swelling was derived. The resulting partial differential equation was solved using a finite difference ...
Low-coverage heteroepitaxial growth with interfacial mixing
(IOP Publishing, 2015-01)
We investigate the influence of intermixing on heteroepitaxial growth dynamics, using a two-dimensional point island model, expected to be a good approximation in the early stages of epitaxy. In this model, which we explore ...
Determinación del coeficiente de auto-difusión superficial del hielo ihDetermination of the superficial self-diffusion coefficient in ih-ice
(Asociación Física Argentina, 2019-04)
En este trabajo se estudió la evolución del ancho del surco formado por la intersección del borde de grano (BG) en una muestra de hielo bicristalina con la superficie libre de la misma. La muestra de hielo estudiada tenía ...
Active carpets drive non-equilibrium diffusion and enhanced molecular fluxes
(Nature, 2021)
Biological activity is often highly concentrated on surfaces, across the scales from molecular motors and ciliary arrays to sessile and motile organisms. These 'active carpets' locally inject energy into their surrounding ...
