XPS presented in Figure shows the form of deposit was indeed a yttrium. Carbon was also a surface contaminant as seen by the carbon peak indicated. as with barium, after sputtering However, for one minute with argon, the carbon contamination was removed and the film showed a deposit free 79 I of carbon contamination as seen in the.

Authors: Paulson, W M Publication Date: Sun Jan 01 EST Research Org.: Ames Lab., Iowa OSTI Identifier: Report Number(s): IS-T A high‐temperature investigation of the vapor in thermodynamic equilibrium with Y–C condensed system was carried out in the temperature range °—°K. Y and YC 2 are shown to be important species in the vapor by: The solubility limits of yttrium and the lanthanide rareearth elements in chromium and chromium-iron alloys were investigated at deg F and at room temperature.
Yttrium also finds use in fuel cells for powering cars and buses, computers and digital phones and, potentially, buildings. A small amount of yttrium oxide is added to zirconium oxide to make what is known as yttria-stabilized zirconia (also called YSZ).
The G phase present in the ex-service alloy is reversed into MC carbides by a heat treatment at °C, associated to a slight decrease in creep resistance.
Besides, the addition of silicon is. The terms “interstitial compound” and “interstitial phase” are commonly applied to the compounds of the transition metals with the light nonmetals Chemical crystallography of tungsten nitrides and of some other interstitial phases, Soviet Phys.

Šulc, H. Jelínková, in Lasers for Medical Applications, Nd-doped lasers. Trivalent neodymium ion Nd 3 + was the first lanthanide from rare-earth elements used for the generation of laser radiation. The Nd:CaWO 4 laser was developed in (Johnson and Nassau, ).Historically, it was the third laser which was put into operation (the first was ruby, the second the U 3 +:CaF.
In the current study, carbon nanofibers (CNFs) were grown on a carbon fiber (CF) surface by using the chemical vapor deposition method (CVD) and the influences of some parameters of the CVD method on improving the mechanical properties of a polypropylene (PP) composite were investigated.

The YCo 3 –H system is an interesting system, which shows a dramatic influence of hydrogen absorption on its magnetic properties.
The β-hydride phase has been divided into β 1 and β 2 phases originally due to their different magnetic properties.

The main purpose of this study is to study vibrational spectra of YAB and reveal or exclude a possible portion existence of the monoclinic (C 2/ c) phase in trigonal (R 32) YAl 3 (BO 3) 4 lattice.
The results of this work can be used in part to study vibrational properties of a set of ReM 3 (BO 3) 4 family members. The organic phase was collected, vacuum distilled and after liquid chromatography ( hexanes: ethyl acetate, silica gel stationary phase) to obtain a clear oily product (g).
