Electrical impedance spectroscopy is a widespread characterization method for solids or fluids in industrial applications. We here report on its thermal equivalent, the “thermal impedance spectroscopy”, improved by using a temperature compensation method for temperature dependent thermal measurements using an on-chip reference resistor.

Coprecipitation Route

We present a study of electrical properties and catalytic activities of materials belonging to the hydrated carbonated systemLa2O3–CO2–H2O. The polycrystalline hydroxycarbonate, dioxycarbonate, and oxide are prepared via a coprecipitation route followed by heat treatment. The electrical conduction of the phases obtained by thermal decomposition fromLaOHCO3,H2Ois analyzed by electrical impedance spectroscopy, from25°Cto950°C, under air. The catalytic properties ofLaOHCO3,La2O2CO3andLa2O3polycrystalline phases are studied by FTIR spectroscopy, in presence of gas mixtures CO-air andCH4-air, at temperatures ranging between100°Cto525°C. The three materials behave differently in presence of CO orCH4gases.

Complex Liquids

Rapid characterization of complex liquids such as solutions, mixtures, dispersions, and emulsions is useful in a variety of industrial applications ranging from cosmetics, pharmaceuticals, to petroleum production. An electrical impedance spectroscopy (EIS) based technique for rapidly determining the characteristics of liquid-liquid mixtures is presented in this study. A milli-fluidic liquid film impedance measurement cell is developed employing 3D printing technology. The cell is tested using glycerol-water mixtures followed by castor oil in water emulsion samples. Frequency response analysis and equivalent circuit modeling are performed on each sample to quantify the emulsion properties in the form of equivalent capacitance and resistance. The developed technique provides an inexpensive and disposable, yet robust experimental platform for applying EIS to investigation and rapid estimation of different properties of oil-water emulsions.
