Thermodynamic properties of alloys of praseodymium with the gallium-indium eutectic melt

Equilibrium potentials of Pr-In alloys containing 8.7–12.1 mol % Pr and alloys of Pr with In-Ga eutectic saturated by praseodymium up to 6.71 mol % Pr are measured by the emf method between 573–1073 K in the (Li-K-Cs)Cleut based salt melt. Metallic praseodymium is used as the reference electrode when studying the Pr-In system, and the two-phase praseodymium-indium alloy L + PrIn3 with the known thermodynamic properties having no phase transitions in the studied temperature range is used as the reference electrode when studying the Pr-In-Ga system. Partial thermodynamic properties and activity of praseodymium in alloys with indium and the Ga-In eutectic mixture are calculated.

S intrinsic electrical properties of single cells i.e., specific membrane capacitance (Cspecific membrane) and cytoplasm conductivity (σcytoplasm) are promising biophysical markers for cell status evaluation and cell type classification. In this talk, I will present our recent work on developing microfluidic platforms enabling the characterization of Cspecific membrane and σcytoplasm in a continuous manner. From the perspective of technology development, I will also present four-generation microfluidic platforms for cellular electrical property quantification and highlight the proposed equivalent circuit models for raw electrical data translation. As to applications, I will report the classification of: Mouse tumor samples; Tumor cell lines with single oncogenes under regulation; Paired high and low-metastatic carcinoma strains; and stem cells in the process of differentiation. The microfluidic platforms developed in this study showed cell type classification, which may function as effective tools in further applications.
