Optically tuned superconductive-dielectric resonators with whispering-gallery modes

An analytical method is presented for calculating the resonant frequency andQ-factor of a superconducting dielectric disk resonator operating in millimeter-wave regime with whispering-gallery mode. Resonant frequency shift due to the optical generation of quasi-particles in superconducting film is investigated as a function of photon flux. An optically tunable resonant frequency of about 500 MHz is estimated, and good agreement is found between numerical results and experimental ones.

Nanoparticles and Their Effective Use in the Technology of Highly Concentrated Binding Suspensions (HCBS) and Refractory Castables. Part 1

General aspects (including terminology) related to the use of ultradisperse particulates (nanosystems) are discussed. The important role of nanoparticles in the technology of highly concentrated binding suspensions (HCBS) and refractory castables is emphasized. Using nanoparticles provides a route toward improving the rheotechnologic properties of HCBS and HCBS-based molding mixtures as well as the structure and service properties of the end product.

V-Si-Sb phase diagram. Isothermal section at 1070 K

The interaction of components in the V-Si-Sb system is examined at 0.7 mole% Sb using an x-ray analysis. An isothermal section of the phase diagram is constructed at 1070 K. The existence of V₄SiSb₂ with the W₅Si₃-type structure is not confirmed. Based on VSi₂ (CrSi₂ structure type), V₅Si₃ (W₅Si₃), VSb₂ (CuAl₂), VSb (NiAs) compounds, terminal solid solutions are formed. Their solubility is lower than 0.05 mole% of the third component. A continuous series of solid solutions exists between V₃Si and V₃Sb (Cr₃Si). The interaction of components in related systems is analyzed.
