The topology of materials is an important structural feature, which cannot be determined from crystallographic information in crystalline materials and pairwise correlations in disordered materials. We extracted the density-driven modification of the topology of tetrahedral silica (SiO2) crystals, siliceous zeolites (MFI, SOD, and FAU), and glass o...

Synthesizing densified glasses with structure ordering is an important issue for the development of new optical fibers with high refractive index and low dispersion. Herein, we report on our attempt to synthesize densified silica (SiO2) glasses by hot compression at a pressure of 7.7 GPa and temperatures above 1200 °C. We succeeded for the first ti...

The intermediate-range order of covalently bonded glasses has been extensively studied in terms of their diffraction peaks observed at low scattering angles; these peaks are called the first sharp diffraction peaks (FSDPs). Although the atomic density fluctuations originating from the quasilattice planes are a critical scientific target, direct exp...

Yttrium-based superconductors (YBCO) haven’t been widely applied. One reason is because of its high cost. In this study, we replaced the substrate and the fabrication method with lower-cost one, and found the possibility of making high-performance superconducting wires. Specifically, YBCO layer was fabricated by Electrophoretic deposition (EPD). Fa...

1. Introduction Yttrium-based superconductors（YBCO）are expected to be applied to transmission lines. But, it haven’t been widely used, one of the reason is that the substrate and the film formation are too expensive. In order to solve these problems, using stainless steel and an Electrophoretic Deposition method (EPD) method were adopted as a new s...
