Review on Mechanism of Facilitated Transport on Liquid Membranes
Membrane processes are used in various felds such as the environment, agriculture and different industrial sectors. These clean techniques are often adopted for directed processes such as treatment, recovery, valorization and separation. In this review article, the theoretical principles and the different classifcations of liquid membranes, such as supported liquid membra...
متن کاملStudies on Permeability of Membranes
A STUDY OF THE BEHAVIOR OF THE DRIED COLLODION MEMBRANE TOWARD THE BIVALENT CALCIUM ION SHOWED THAT: 1. There is almost no potential difference established across a membrane separating two calcium chloride solutions of 0.1 and 0.01 N concentrations. 2. The transfer numbers of chlorine and calcium, as measured in electrical transfer experiments, are both close to 0.5. 3. A sample of membrane in ...
متن کاملStudies of charge transfer at liquid liquid interfaces and bilayer lipid membranes by scanning electrochemical microscopy
The principles of scanning electrochemical microscopy (SECM) and its application to studies of electron transfer at the interface between two immiscible electrolyte solutions are reviewed. The results of SECM measurements with a number of redox couples at the bare liquid liquid interface or an interface with a lipid monolayer suggest that the electron transfer follows that predicted by Marcus t...
متن کاملIn Vivo and in Vitro Studies on Stigmasterol Isolated from Pedalium Murex
In the present study, stigmasterol has been reported from Pedalium murex L. of pedaliaceae family in vivo and in vitro. Quantification data revealed that the total sterol content was higher in callus than leaves. The in vitro studies showed that the maxmium amount of total sterol was found in 6 weeks old tissue and minimum in 2 weeks old callus culture. In vivo studies showed that higher conten...
متن کاملStigmasterol: a Comprehensive Review
Extensive research has been carried out from last decades to discover potential constituents from plant sources. Stigmasterol is an important constituent and has been isolated from plants. It is involved in the synthesis of many hormones like progesterone, androgens, estrogens and corticoids. In addition to stigmasterol many of its derivatives like, spinasterol, fucosterol, cyasterone, stigmast...
