In this article, a high-throughput screening method for thin-film magnets was proposed. Composition gradient thin films were deposited using a sputtering machine which equipped a substrate rotation and a moving mask mechanism. Local surface leakage m

We recently invented a method called the flux-film-coated technique for purifying a GaN wafer with low dislocation density grown from point-seed crystals. In this study, we investigated the mechanism behind the reduction of dislocation density in the

In a previous report, we demonstrated the monitoring of electrical resistance of Ga-Na melt and revealed the time dependency of the nitrogen dissolution in Ga-Na flux. In-situ monitoring of nitrogen dissolution process into the Ga-Na melt is importan

The electrical resistance of Ga-Na melt used for gallium nitride crystal growth on a Na flux was investigated with the four-point probe method. Electrical resistance of melt was measured isothermal at 870 °C as the function of time. Pressure decay m

In a previous study, we successfully obtained large-diameter, low-dislocation-density GaN wafer using the Na-flux multi-point seed (MPS) technique. However, the lattice constants of the GaN wafer grown by this technique expanded due to oxygen concent

Geographical variation in the diet of sika deer Cervus nippon Temminck, 1838 has been well characterised: northern populations are grazers, whereas southern deer are browsers. This variation largely reflects genetic-based differences in morphology. H

A thermodynamic model was derived to evaluate the surface tension of molten ionic mixtures by considering the ratio of the radius of cation to that of anion. The present model reproduces the following characteristics of the composition dependence of

Objectives: We aimed to determine the correlation of radiographic contrast material distribution with selective lumbosacral nerve root block (SLNRB)-induced radiating pain and pain reduction obtained 3 ± 1 hours after SLNRB. Patients were stratified
