Surface oxide on thin films of yttrium hydride studied by neutron reflectometry [PDF]
The applicability of standard methods for compositional analysis is limited for H-containing films. Neutron reflectometry is a powerful, non-destructive method that is especially suitable for these systems due to the large negative scattering length of H.

Reactions of alkaline earth zirconate refractories with titanium alloys [PDF]
The severe reactivity of titanium alloys with ceramics is a major challenge for their processing. Up to now refractories to melt and cast titanium alloys are selected on the basis of a low Gibbs energy of formation. This kind of selection assumes that an

The effect of yttrium ion implantation on the sulphidation of incoloy 800H [PDF]
Previous work has shown the beneficial effect of yttrium implantation on the oxidation behaviour of chromium oxide forming alloys. Because of the limited applicability of Fe-Cr-Ni alloys in sulphur containing gases the effect of yttrium implantation on ...

Impact of magnesium oxide concentration and yttrium-aluminum garnet stoichiometry deviation on the microstructure and optical transmission of YAG-based ceramics [PDF]
The paper investigates the effect of the magnesium oxide concentration on the ceramics’ microstructure and optical transmittance under conditions of excess Al3+ (4.8 mol.%) and Y3+ (2.9 mol.%) cations in the garnet structure, as well as the ...

Transparent yttrium hydride thin films prepared by reactive sputtering [PDF]
Metal hydrides have earlier been suggested for utilization in solar cells. With this as a motivation we have prepared thin films of yttrium hydride by reactive magnetron sputter deposition.

Gold Nanoparticles on Yttrium Modified Titania: Support Properties and Catalytic Activity [PDF]
A series of titanium oxide catalysts modified with yttrium has been prepared by sol¿gel method and their structural properties have been studied. The incorporation of yttrium in the titania lattice favors the formation of oxygen vacancies while at low Y ...
