The pH-sensitive chromoionophores brought the dream of the ion-selective membrane scientist close to realization. With the help of these molecules, one can build pH-sensitive, ion-selective electrodes and look into the bulk of solvent polymeric membranes during potentiometric measurements (spectropotentiometry) and image concentration profiles in situ with high spatial and temporal resolution. ...

In this work, the results concerning to the mean activity coefficient measurements for NaCl in the (glycerol + water) system using the potentiometric method are reported. The potentiometric measurements were performed on the galvanic cells without liquid junction of the type: Ag|AgCl|NaCl (m), glycerol (wt%), H2O (1 - wt)%|Na-ISE, in various mixed solvent systems containing 0, 5, 10,...

The thesis aims at the characterization of the p-electronic conduction parameter of cation conducting solid electrolytes. For this purpose potentiometric as well as thermoelectric measurements were carried out. The investigations have been done on commercially available potassium and sodium beta alumina as well as on laboratoryprepared samples of NASICON. The information about the p-electronic ...

The synthesis and characterization of solid complexes for pantoprazole sodium sesquihydrate (PNZ) with Cd(II), Hg(II) and Zn(II) metals in molar ratios M:L = 1:2 was studied. The complexes are stable in the solid state and are soluble only in DMF and DMSO. The metal complexes were characterized by elemental analysis, molar conductivity measurements, magnetic susceptibility, UV spectrophotometry...

The discovery of spin-polarized states at the surface of three-dimensional topological insulators (TI) like Bi2Te3 and Bi2Se3 motivates intense interests in possible electrical measurements demonstrating unique signatures of these unusual states. Here we show that a three-terminal potentiometric set-up can be used to probe them by measuring the voltage change of a detectingmagnet upon reversing...

We here report on the first example of an aptamer-based potentiometric sandwich assay of proteins. The measurements are based on CdS quantum dot labels of the secondary aptamer, which were determined with a novel solid-contact Cd2+-selective polymer membrane electrode after dissolution with hydrogen peroxide. The electrode exhibited cadmium ion detection limits of 100 pM in 100 mL samples and o...
