| Description
| - Studovaný mikrosystém sestává ze dvou rezervoárů obsahující vodné elektrolyty uhličitanu draselného a chloridu vápenatého a mikrokapiláry obsahující hydrogel. Když vápenaté a uhličitanové ionty difundují a migrují v elektrickém poli do mikrokapiláry, vzniká uhličitan vápenatý, který může způsobit ucpání mikroapiláry. Byly pozorovány kvalitativně odlišné koncentrační struktury v závislosti na aplikované intenzitě elektrického pole, například rozštěpení píku koncentrace uhličitanu vápenatého. Oblasti s rizikem ucpání mikrokapiláry sraženinou uhličitanu vápenatého byly určeny v parametrickém prostoru. (cs)
- The studied microsystem consists of two reservoirs containing aqueous electrolytes, a solution of potassium carbonate and a solution of calcium chloride, separated by a microcapillary containing a hydrogel. As the calcium and the carbonate ions diffuse and/or migrate in electric field in the microcapillary, calcium carbonate is formed and the risk of clogging increases at the locations where the concentration product of the calcium and carbonate ions exceeds the CaCO3 solubility product.Two qualitatively different spatio-temporal concentration patterns in the microcapillary of finite length in dependence on the applied difference of the electric potential have been found by means of the dynamical analysis. We have observed patterns with one and two maxima on the spatial profile of reaction rate of the calcium-carbonate interaction. Bifurcation diagram, in which the peak splitting has been clearly detected, was computed in dependence on the imposed gradient of electric potential. The peak splitting and
