Double‐diffusive layers in the Adriatic Sea [PDF]

open access: yesGeophysical Research Letters, 2008
A microstructure profiler was deployed to make turbulence measurements in the upper layers of the southern Adriatic Sea in the Mediterranean during the Naval Research Laboratory (NRL) DART06A (Dynamics of the Adriatic in Real Time) winter cruise in March 2006.

Construction of diffusion layers based on cipher structures

open access: yes网络与信息安全学报, 2017
Taked diffusion layers of block cipher algorithms as the research object,lightweight diffusion layers were constructed by two cipher structures based on the characteristics of diffusion layers of lightweight block cipher algorithms,which were the ...

Nonlinear Horizontal Diffusion for GCMs [PDF]

open access: yes, 2007
The mixing-length-based parameterization of horizontal diffusion, which was originally proposed by Smagorinsky, is revisited. The complete tendencies of horizontal momentum diffusion, the associated frictional heating, and horizontal diffusion of ...

Study of local diffusion coefficients of the hydration layer of lipid vesicle bilayers [PDF]

open access: yes, 2009
Water molecules near the surface of vesicle bilayers exhibit slow dynamics with respect to that of pure bulk water as they belong to the hydration layer.

Diffusion in Cauchy Elastic Solid [PDF]

open access: yes, 2022
It is commonly accepted that a starting point of the science of diffusion is the phenomenological diffusion equation postulated by German physiologist Adolf Fick inspired by experiments on diffusion by Thomas Graham and Robert Brown.

Study on water and oxygen transfer characteristics of HT-PEM fuel cells

open access: yesHeliyon, 2023
In this study, a steady-state model is developed by combining mechanical, Navier–Stokes, Maxwell–Stefan, and Butler–Volmer equations. This model is then used to investigate the influences of diffusion layer thickness deformation under a specific assembly

Diffusion in Metals and Intermetallics: An Overview [PDF]

open access: yes, 2022
After a few remarks about the history of diffusion in solids we remind the reader to some basics of diffusion such as tracer diffusion, interdiffusion, high-diffusivity paths, and basic diffusion mechanism in solids.

Drift-diffusion of highly mobile dopants in CdTe [PDF]

open access: yes, 2008
The diffusion of Ag in CdTe exhibits anomalous concentration profiles, which essentially reflect the profile of the deviation from stoichiometry. At a diffusion temperature of about 800 K, the Ag dopant atoms are present as charged interstitials.
