Special Issue “Advances in Artificial and Biological Membranes: Mechanisms of Ionic Sensitivity, Ion-Sensor Designs, and Applications for Ion Measurement”

Membranes, 2020
Ion sensors, conventionally known as ion-selective membrane electrodes, were devised 100 years ago with the invention of a pH electrode with a glass membrane (in 1906 Cremer, in 1909 Haber and Klemensiewicz) [...]

Ion-selective interface engineering for durable electrolysis of impure water

Nature Communications
Electrolysis of low-grade impure water offers a sustainable approach to hydrogen production. However, unstable interfacial pH caused by electrochemical reactions accelerates ion-induced electrode degradation. Here, we show an ion-selective gate strategy,

A Comparative Study of Ag+-Selective Electrodes Based on Two 21-Membered N3S4-Macrocycles as Neutral Ionophores

International Journal of Electrochemical Science, 2012
The performances of two 21-membered N3S4-azathiacrown ethers as neutral carriers for Ag+-selective electrodes (Ag+-ISEs) were investigated. Potentiometric responses revealed that the flexibility of the crown ether has great effect on the selectivity and ...

Determination of fluoride in plant material using microwave induced oxygen combustion

Czech Journal of Food Sciences, 2012
Fluorine is essential in human and/or animal nutrition, thus it is important to know its concentration in a diet. One of the important sources of fluorine for humans is tea, containing relatively high amounts of this trace element.
