Hydrogen trapping and interfacial decohesion at the α-Al2O3(0001)/Fe(110) interface
Youngseok Hwang, Norihito Sakaguchi, Yuji Kunisada
Hydrogen embrittlement and tritium leakage pose critical challenges for fusion reactor structural components, rendering α-Al2O3/Fe interfaces vital as tritium permeation barriers.…
First-principles study of formic acid decomposition on single Pt atoms supported on heteroatom-doped graphene
Kazuma Sato, Norihito Sakaguchi, Yuji Kunisada
Formic acid is a promising liquid hydrogen carrier, but its catalytic decomposition requires both high activity and selectivity toward dehydrogenation. Here, we investigated the ca…
Unveiling the origin of diffusion suppression of hydrogen isotopes at the α-Al2O3(0001)/α-Cr2O3(0001) interfaces
Yuji Kunisada, Ryotaro Sano, Norihito Sakaguchi
It has been reported that the α-Al2O3, a promising tritium permeation barrier material for a fusion reactor, can be grown at low temperatures on the α-Cr2O3 template, and that α-Al…
Two-Dimensional Quantum Dynamics of O Dissociative Adsorption on Ag(111)
Yuji Kunisada, Norihito Sakaguchi
We have investigated the quantum dynamics of O2 dissociative adsorption on a Ag(111) surface. We performed the calculations with a Hamiltonian where the O2 translational motion is…
