diffusively

Then in this diffusively fluctuating state, intense local changes occur at random times and locations in the shear layer near the wall.

Diffusive (or passive) sampling - A tube is packed with a single sorbent bed and allowed to adsorb analytes from the air diffusively.

In addition to molecular hydrogen, the thermosphere contains a large proportion of free hydrogen atoms, while helium is thought to be absent here, because it separates diffusively at lower altitudes.

Some models of the ocean circulation suggest that broad-scale upwelling occurs in the tropics, as pressure driven flows converge water toward the low latitudes where it is diffusively warmed from above.

Geometric albedo is the ratio of the brightness of an astronomical body at a phase angle of zero to an idealized flat, fully reflecting, diffusively scattering (Lambertian) disk with the same cross-section.

Alternatively, at higher gas pressures, the ions collide with the gas atoms that act as a moderator and move diffusively, reaching the substrates or vacuum chamber wall and condensing after undergoing a random walk.

Ions are deemed to have access to protein and lipid regions and if any point within the finite-size of ionic sphere crosses the protein or membrane boundary, a collision is assumed and the ion is reflected diffusively.
