The interaction of anionic dye Acid Green 25 (AG) with cationic surfactant cetylpyridinium chloride (CPC) was studied by spectrophotometric method in 25oC and conductometric method in 25, 30, 35, 40 and 45oC. The specific conductance of dye – surfactant mixtures was measured. A decrease in measured specific conductance values of dyesurfactant mixture was caused by the formation of nonconducting...

This paper presents, discusses, and compares the results of determination of tetrafluoroborate and chloride anions by isotachophoresis (ITP) and ion chromatography (IC) with conductometric detection. Tetrafluoroborate and chloride anions are the ones of the most important (and most often used) anions in the molecules of ionic liquids. The achieved limit of detection (10 μg L–1) was very satisfa...

Properties of propagation modes for a layered ZnO/XZ LiNbO3 surface acoustic wave sensor have been investigated both theoretically and experimentally. By calculating the effective permittivity function, it was shown that after the ZnO deposition two distinct propagation modes have been generated: a Rayleigh and a shear horizontal. A layer of InOx was deposited to provide a conductometric sensin...

− The paper presents a dedicated IEEE 1451.1 Transducer Block that enables plug & play transducers according to the recommendations of the IEEE 1451.4 standard. The Transducer Block is self-configurable based on the information stored in the Transducer Electronic Data Sheet (TEDS): basic TEDS and transducer type templates are used for transducer self-identification; and calibration templates ar...

In this paper the first example of using C-dots (CDs) as sensing nanomaterial for monitoring low concentrations NO2 in ambient air is reported. logic to support a green circular economy, CDs were prepared from natural cost precursor consisting olive solid waste (OSW) by simple pyrolysis process combined with chemical oxidation. Characterization data showed formation spherical dimensions narrow ...
