Visulex-P is based on passive diffusion to deliver small molecules such as most generic corticosteroids and immunosuppressive agents whereas Visulex-I, its complementary technology for macromolecule delivery, is based on electroosmosis
which employs ocular iontophoresis.
(ICEO) is a phenomenon driven by electrostatic forces under applied electric field and is a variant of the electroosmotic phenomenon .
Nowadays, dewatering method mainly includes large diameter well, radial well, electroosmosis
well, light well point, and vacuum tube well.
Asadi A, Huat BBK, Nahazanan H, Keykhah HA (2013) Theory of electroosmosis
Iontophoresis is based on the constant electric current to run charged drug molecules over the skin by means of electrophoresis as well as electroosmosis
The process, says Athmer, was modeled off of a similar technique called electroosmosis
, which has been used successfully in Kentucky, Ohio, and Wisconsin to clean soil of industrial solvents, such as trichloroethylene.
Among the requirements for the proton exchange membrane, that are used in water electrolysis, are high proton conductivity, low electron conductivity, low permeability of the gases (hydrogen and oxygen), high chemical stability in the acidic media, providing high speed electrode reactions, mechanical strength in the dry and humid condition, minor water transport across the membrane by diffusion and electroosmosis
effects, as well as availability of materials and low production cost.
is based on the electrokinetic effects of an electric field on porous systems as a result of the formation of a double electrical layer at a solid-fluid interface.
EMDA/iontophoresis, with the topical application of verapamil or verapamil plus dexamethasone, is thought to enhance transcutaneous absorption of the drugs via electrophoresis, electroosmosis
, or enhanced diffusion using surface-delivered heat or current (Greenfield, Shah, & Levine, 2007).
To be applied in polymer electrolyte membranes fuel cells (PEMFCs), the advanced membrane materials should meet the following requirements: (i) high ionic conductivity; (ii) low fuel permeability; (iii) good thermal and hydrolytic stability; (iv) excellent electrochemical stability in an aggressive environment; (v) substantial morphological and dimensional stability; (vi) outstanding mechanical properties in both the dry and hydrated states; (vii) sufficient water uptake and moderate swelling; (viii) suppressed water transport through diffusion and electroosmosis
; (ix) easy fabrication to form the membrane electrode assembly (MEA), and finally, more importantly from a practical point of view; (x) a competitive low-cost and sufficient long-term durability [7, 8].
