The Stokes-Einstein-Sutherland (SES) equation is at the foundation of statistical physics, relating a particle's diffusion coefficient and size with fluid viscosity, temperature, boundary condition for particle-solvent interface. It assumed that it relies on separation scales between particle solvent, hence expected to break down diffusive transport molecular scale. This assumption however challenged by number experimental studies showing remarkably small, if any, violation, while...
Mineral dust is the most abundant type of atmospheric aerosol in terms mass. Dust models at non-storm resolving resolutions are usually able to capture load on diurnal or longer-term average, but perform worse capturing its variability. A main reason for this deficit fact that phenomena smaller than grid size cannot be represented and therefore lacking simulations. major dust-event can only single-digit kilometer resolution haboobs – intense storms created by cold-pool outflow...
Haboob dust storms, formed by the cold pool outflow from moist convection, play a significant role in global emissions. However, they are largely absent current climate models, as most do not explicitly resolve convection processes, leading to considerable inaccuracies modeling and its impacts. Therefore, influence of haboobs on cycle Earth system remains poorly understood. With advent kilometer-scale there is unique opportunity unveil haboob behavior advance our understanding their...
Mineral dust is one of the most abundant types aerosol particles in atmosphere, playing a crucial role various atmospheric processes. A key interaction within clouds its ability to produce ice-nucleating (INPs), influencing cloud properties such as phase, lifetime, and water content. The efficiency mineral INPs depends on factors mineralogy, composition, particle size. This study investigates size mineralogy INP efficiency, contrasting Morocco Iceland, i.e. mid- high-latitude sources by...
Diffusion in confinement is an important fundamental problem with significant implications for applications of supported liquid phases. However, resolving the spatially dependent diffusion coefficient, parallel and perpendicular to interfaces, has been a standing issue. In vicinity density fluctuations as consequence layering locally impose statistical drift, which impedes analysis coefficients even further. We hypothesise, that we can derive model resolve interface-perpendicular based on...

Hypothesis:Diffusion in confinement is an important fundamental problem with significant implications for applications of supported liquid phases. However, resolving the spatially dependent diffusion coefficient, parallel and perpendicular to interfaces, has been a standing issue objects nanometric size, which structurally fluctuate on similar time scale as they diffuse, no methodology established so far. We hypothesise that complex, coupled dynamics can be captured analysed by using model...
Accurate modeling of diffusive transport nanoparticles across nanopores is a particularly challenging problem. The reason that for such narrow pores the large surface-to-volume ratio amplifies relevance nanoscopic details and effective interactions at interface with pore walls. Close to wall, there no clear separation between length scales associated molecular interactions, layering solvent particle size. Therefore, standard hydrodynamic arguments may not apply alternative solutions...
