A method of depicting the diagram for ion-exchange processes, interrelating the composition of the solution, composition of the ion-exchange resin, coefficient of separation, swelling capacity of the ionexchange resin, and amount of nonexchange-sorbed electrolyte was proposed.A selectivity versus ...
13.3.3.2Ion exchange Ion exchangeis a process similar tosorption, with only one key difference, that is, ion exchange is a stoichiometric process where every ion that is taken up by the solid phase is replaced stoichiometrically by the counterion on the solid surface, whereas in sorption the ...
Other ion transporters can couple the movement of one ion to another one — either as cotransport into the same direction (symporter), or in an exchange process (antiporter). Whereas these transporters are also ‘passive’, so-called ‘pumps’ use the energy derived e.g. from ATP hydrolysis...
Below is a high-level functional diagram of ION’s topology which includes nodes that embed IPFS CIDs into Bitcoin, retrieve and replicate DID operation data via the IPFS protocol, and process DID operations in accordance with ION’s deterministic protocol rules. ...
Schematic diagram showing the core-shell atomic exchanges at the In(Zn)P/ZnS interface. Full size image It is plausible that ion exchange is aided by the presence of P vacancies in the core as this would encourage the diffusion of S into the core. One indication of the presence of P vac...
Fig. 5: Pulse sequence diagram for the Ramsey-type experiment. The relative times of the different processes are represented on the same time axis (not to scale). From the top down the axes are: the on/off times for the 369.5 nm Doppler cooling laser, the electro-optic modulator (EO...
Fast molecule-ion exchange is necessary for fast ion conduction in liquid electrolytes. In contrast, in crystalline solids, the diffusion of mobile species, such as lithium ions, encounters periodic BN points offered by immobile framework species. These points define energetic barriers that separate tw...
which is due to Na+ ions flowing from outside to inside the cell to sodium channels in the plasma membrane. In exchange, K+ flow outside the cell after a delay (absolute refractory period) and cessation of the action potential. Subsequent to K+ ions leaving the cell, the membrane potenti...
The initial experiments were planned just to test the feasibility of SDM ion-exchange chromatography. It is anticipated that optimization of the process parameters would lead to higher product recoveries, along with increasing the specific activity [or purification (fold)] of the STI recovered. These...
[62]. By contrast, in otherelectrochemical desalinationmethods such aselectrodialysisand capacitive deionization, both cations and anions are removed from the feed via ion-selective electrodes or ion exchange membranes. In an ICP process, whenion concentrationbecomes polarized across the membrane, a ...
