Ce-doped RE3Al5O12 (Ce:REAG, RE=Tb, Dy, Ho, Er, Tm and Yb) single crystals were synthesized by the optical Floating Zone method. The transmittance is approximately 80% in all the samples, and absorptions by rare-earth ions were observed. Under X-ray

Yb3Al5O12 (YbAG) single crystals were prepared by the Floating Zone (FZ) method with and without doping with different concentrations of Ce, and then we evaluated their basic scintillation properties. All the samples showed scintillation with emissio

Ni50Mn50-x Ga x/2In x/2 magnetic shape memory alloys were systematically prepared, and the magnetic properties as well as the phase diagram, including atomic ordering, martensitic and magnetic transitions, were investigated. The B2–L21 order–diso

In this study, we investigated the photocatalytic properties of perovskite-type oxides BaLnO3 (Ln = Ce, Pr, and Tb). Both Pt-loaded BaCeO3 and Pt-loaded BaPrO3 show no photocatalytic activity under blue LED irradiation; however, Pt-loaded BaTbO3 show

We have found that use of a highly graphitized carbon as a catalyst support leads to the loss of power performance at low humidity even though voltage holding durability is greatly improved. This finding motivates current study of the influence of ca

The decoloration of amaranth, as one of the azo dyes widely used in the dyeing industry, was carried out using a two-compartment cell separated by Pd sheet, palladized Pd (Pd/Pd black) sheet and platinum-modified palladized Pd (Pd/Pd black/Pt) sheet

Stereochemical studies on the palladium-catalyzed asymmetric 1, 3-rearrangements of [4-chiral arylsulfinyl-1, 3( E or Z )-butadienyl]cyclopropanes to chiral cyclopentenes are described. The plausible mechanism for the rationalization of the stereoche

A successive hydrogenation system was constructed using a two-compartment cell separated by a Pd sheet. The hydrogenation rate changed greatly, depending on the kind of substrates used. For the purpose of improving the hydrogenation rate, the surface

Chemical deposition of foreign metals such as Pt, Au, Cu and Zn on a Pd sheet was carried out by using hydrogen atoms passing through the Pd sheet (thickness, 50 μm) which served as a working electrode for water electrolysis to produce H atoms, a se

A Pd sheet electrode was chemically palladinized with active hydrogen passing through it. The Pd black deposits grew up three-dimensionally with increasing palladinization time, causing the marked increase in reaction zone or number of reaction site
