The phrase "active permeation" is correct and usable in written English.
It can be used in contexts related to processes involving the movement or diffusion of substances, particularly in scientific or technical discussions.
Example: "The study focused on the active permeation of nutrients through the cell membrane, highlighting the mechanisms involved."
Alternatives: "dynamic diffusion" or "energetic penetration".
This work presents a mass-balance-based model devoted to the characterization of intercrystalline defects active to permeation in film-like zeolite membranes using pervaporation data.
Particles were formed as described in Figure 6, followed by the addition of either 1 µM NTF2-Atto488 or ImpβIBB-GFP and 3 µM mCherry as active and passive permeation probes, respectively.
CLSM images were taken ≈2 3 min later, using the 405 nm, 488 nm, or 561 nm laser lines for exciting the FG tracer, active or passive permeation probes, respectively.
In contrast to conventional modes of administration, rapid permeation of active molecules through brain capillaries is the most significant barrier to effective drug distribution in the brain.
They considered passive permeation and active efflux mediated by P-gp in their approach [ 33].
Skin permeation of active ingredients from a w/o emulsion may be influenced by solubility capacity of a compound in both organic and aqueous phases.
Salt transport in the interstitial space combines active transport and passive permeation processes: (19) d (q s c s ) d x = + P (c a ) − H d (c s − c d ) − H c (c s − c c ). Equation (19) assumes that the combined interstitial and vasa recta space gathers the sum of the fluxes from the other structures.
"There are different [inert] components in a formulation," explains Monica, who was investigating "how they affect the permeation of actives through the skin".
In the next step of purification by Sephadex G-75 gel permeation chromatography, four active fractions having laccase activity were pooled.
Firstly, the 3D C/TiO2 nanowire arrays, as excellent platform for loading active materials, can facilitate the permeation of electrolyte.
