Investigation of Cu Diffusivity in Fe by a Combination of Atom Probe Experiments and Kinetic Monte Carlo Simulation
Autor: Yasuyoshi Nagai, Can Zhao, Koji Inoue, Takeshi Toyama, Shigeto R. Nishitani, Tomoaki Suzudo
Publikováno v: MATERIALS TRANSACTIONS. 62:929-934
In the present study, the diffusion coefficient of Cu in Fe was experimentally estimated from the precipitation kinetics down to 390°C. At this temperature, diffusion couples, which is a typical method to obtain diffusion coefficients, cannot be app

Finite-temperature first-principles calculations of Al 〈100〉 symmetric tilt grain-boundary energy
Autor: Shigeto R. Nishitani
Publikováno v: Philosophical Magazine. 101:622-642
The energies of small-angle tilt grain-boundaries have been predicted using the Read–Shockley model based on dislocation theory. However, experimentally observed energies have been inconsistent wit...

Energy of Small Angle Tilt Boundary in Al
Autor: Shigeto R. Nishitani
Publikováno v: Materials Science Forum. 941:2296-2299
The critical inconsistency on the small angle boundary energy between the theoretical prediction of Read-Shockley model and the experimental results was discussed. The plots of the ratio between boundary energyEand the tilt angleθagainst logθshow d

Publikováno v: Journal of the American Chemical Society. 142(1)
Recently, metal-organic frameworks (MOFs) composed of sulfur secondary building units (sulfur-SBUs) have attracted significant attention as unique electronic materials with high conductivities and photo- and electrocatalytic properties. Herein we rep

First Principles Calculations of Solute Ordering in Mg–Zn–Y Alloys
Autor: Yosuke Yamamoto, Shigeto R. Nishitani, Yuichi Sakamoto, Yoshihiro Masaki
Publikováno v: MATERIALS TRANSACTIONS. 54:656-660
The formation mechanism of the LPSO structures of Mg­Zn­Y alloys has been investigated by the energetic assessments with the first principles calculations. For the key players of the LPSO structures, the stacking faults and the solute elements of Z

Metastable solvent epitaxy of SiC
Autor: Shigeto R. Nishitani, Tadaaki Kaneko
Publikováno v: Journal of Crystal Growth. 310:1815-1818
Silicon carbide (SiC) is a promising material for next-generation high-power devices, but the high cost of forming wafers is causing a bottleneck in the replacement of Si with SiC. We report a new solution growth process that exhibits potential for t
