Yttrium-substituted Mg–Zn ferrites: correlation of physical properties with Yttrium content

Anisotropy of Ruthenium-substituted Yttrium-iron-garnet

Use of yttrium 90 in persistent synovitis of the knee. II. Direct comparison of yttrium colloid resin and yttrium citrate.

The choice of radiocolloid for intra-articular therapy depends largely on factors of efficacy and safety. The fl-emission from yttrium 90 (90 Y) has a satisfactory range for use in the knee and a short half-life as well as freedom from gamma-radiation and from contamination. Since the demonstration by Stevenson, Bedford, Hill, and Hill (1971) and Stevenson and 12 others (1973) that chromosomal ...

Preparation and photoluminescence of yttrium hydroxide and yttrium oxide doped with europium nanowires

Single-crystalline Y(OH)3:Eu nanowires have been prepared by polymer-assisted hydrothermal method. The yields of the nanowires were higher than 95%. XRD patterns showed that the products were the hexagonal Y(OH)3 structure. SEM images displayed that the nanowires consisted of nanobelts and nanorods. The nanorods have the diameter of about 85 nm and length up to several tens of microns, and the ...

Zinc and yttrium

Dwarf galaxies are small systems with relatively simple histories. This makes them interesting objects to study a “simple” chemical evolution history. Boötes I belongs to the faintest subclass of dwarf galaxies: ultra-faint dwarf spheroidals, which have very low surface brightness and are dark

Yttrium ethyl­enediammonium squarate tetra­hydrate

The title compound, {(C(2)H(10)N(2))(1.5)[Y(C(4)O(4))(3)(H(2)O)(4)]}(n) {system-atic name: catena-poly[sesqui(ethyl-enediammonium) [[tetra-aquabis-(squarato-κO)yttrium(III)]-μ-squarato-κ(2)O:O']]}, was synthesized by slow evaporation of an acid solution. The asymetric unit contains one yttrium cation in an anti-prismatic environnement, three squarate groups, one and a half protonated ethyl-ened...
