Potassium ion plays a crucial role for the organisms life. Its detection is performed usually by potassium selective electrodes (PSE) having membranes made of a polymer matrix (such as PVC) incorporating macrocyclic compounds as ionophore. We propose a novel potassium selective material (PSM) based on a new synthesized crown-ether ionophore incorporated in carbon paste conductive matrix (PSM-CP). Electrochemical measurements proved the affinity of PSM-CP for the potassium cation, which is selectively bound by entrapping in the crown-ether cavity. The results are comparable with those obtained by using a PSE based on PVC-ionophore membrane.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
