Quartz Whispering-Gallery-Mode Resonator with Microfluidic Chip as Sensor for Permittivity Measurement of Liquids
Alexey I. Gubin, Irina A. Protsenko, Alexander A. Barannik +3
Studies of biological solutions require high measurement accuracy, the ability to detect low changes in substance concentration, and small amounts of the liquid under test. A micro…
On the Issue of Textured Crystallization of Ba(NO) in Mesoporous SiO: Raman Spectroscopy and Lattice Dynamics Analysis
Yaroslav Shchur, Guillermo Beltramo, Anatolii S. Andrushchak +6
The lattice dynamics of preferentially aligned nanocrystals formed upon drying of aqueous Ba(NO) solutions in a mesoporous silica glass traversed by tubular pores of approx…
Whispering-Gallery Mode Resonator Technique with Microfluidic Channel for Permittivity Measurement of Liquids
Alexey I. Gubin, Alexander A. Barannik, Nickolay T. Cherpak +4
Studies of biochemical liquids require precise determination of their complex permittivity. We developed a microwave characterization technique on the basis of a high-quality whisp…
Mesoporous alumina- and silica-based crystalline nanocomposites with tailored anisotropy: methodology, structure and properties
A. V. Kityk, A. Andrushchak, Ya. Shchur +10
We present several recently synthesized nanocomposites consisting of liquid crystals as well as an organic molecular crystal embedded into the nanochannels of mesoporous alumina an…
Millimeter-wave surface impedance of optimally-doped Ba(Fe1-xCox)2As2 single crystals
A. Barannik, N. T. Cherpak, M. A. Tanatar +4
Precision measurements of active and reactive components of in-plane microwave surface impedance were performed in single crystals of optimally-doped Fe-based superconductor Ba(Fe1…
