Production of yttrium aluminum silicate microspheres by gelation of an aqueous solution containing yttrium and aluminum ions in silicone oil
Background: Radioactive yttrium glass microspheres are used for liver cancer treatment. These yttrium aluminum silicate microspheres are synthesized from yttrium, aluminum and silicone oxides by melting. There are two known processes used to transform irregular shaped glass particles into microspheres, these ‘spheroidization by flame’ and ‘spheroidization by gravitational fall...
متن کاملUse 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 ...
متن کاملSynthesis of Iron Yttrium Garnet Nanoparticles by Reverse Microemulsion Method
Colloidal nanodispersion of Iron Yttrium Garnet has been preparedbymixing the two ternary mixture of Triton X-100 (surfactant), n-heptane and aqueous solution that differing only in the aqueous phase.Ethanolwas added as cosurfactant and mixed them by ultrasound bath. By mixing these twomicroemulsions, Iron Yttrium garnet (Y3 Fe5 O12) nanodispersionwas obtained. Solids were settled by centrifuge...
متن کاملZinc 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
متن کاملYttrium 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...
