 (ĕk′sŏz-mō′sĭs, -sŏs-)
The passage of a fluid through a semipermeable membrane toward a solution of lower concentration, especially the passage of water through a cell membrane into the surrounding medium.

ex′os·mot′ic (-mŏt′ĭk) adj.


(ˌɛksɒzˈməʊsɪs; -sɒs-)
(Biology) biology osmosis in which water flows from a cell or organism into the surrounding solution. Compare endosmosis
exosmotic, exosmic adj


(ˌɛk sɒsˈmoʊ sɪs, ˌɛk sɒz-)

1. osmosis toward the outside of a cell or vessel.
2. the flow of a substance from an area of greater concentration to one of lower concentration (opposed to endosmosis).
[1830–40; Latinization of now obsolete exosmose < French; see ex-2, osmosis]
ex`os•mot′ic (-ˈmɒt ɪk) adj.


(in osmosis) the slower spread of the more dense fluid through the membrane to merge with the less dense. Cf. endosmosis. — exosmotic, adj.

Therefore, to address the aforementioned two problems, a joint element and a coupling method for simulating the hydromechanical interaction of the reinforced concrete lining are adopted, which consider the effects of the joint load-bearing characteristics of the steel lining and the consolidation layer and the internal water exosmosis on the stability of the steel lining at the collapse zone.
En 1827, el medico, biologo y fisiologo frances Rene Joachim Henri de Dutrochet Neones descubrio que al someter liquidos de diferentes densidades a traves de membranas (usando material inorganico muy fino de forma cilindrica, dispuesto en un capilar vertical), uno de ellos tiende a ascender mas que los otros, evidenciando asi los fenomenos de endosmosis y exosmosis, concluyendo que hay una relacion directa entre la permeabilidad preferente de un determinado fluido y la altura que este alcanza en el medio filtrante [15-17].
When suffered from waterlogging, membrane of plant cells was damaged, causing the exosmosis of cytoplasm and consequent increasing of conductivity.
