We present wavelengthmultiplexed holographic recording for highdensity, highspeed data storage using reflection geometry with a highsensitivity ceriumdoped strontium barium niobate singlecrystal structure and secondharmonic generated light from a compact and convenient wavelengthtunable laser diode. We have recorded and reconstructed wavelengthmultiplexed holograms by using ...

Rare Earth elements (cerium, dysprosium, erbium, europium, gadolinium, holmium, lanthanium, lutetium, neodymium, praseodymium, samarium, scandium, terbium, thulium, ytterbium, yttrium) The major ore minerals containing rare earth elements are bastnasite, monazite, and loparite and the lateritic ionadsorption clays. Major production of bastnesite is from Mountain Pass, California. Rhenium ...

An aqueous sol–gel synthesis route has been used for the preparation of undoped and ceriumdoped strontium aluminate phase Sr4Al14O25. This study revealed required conditions for obtaining ...

Burbankite is a rare strontium and cerium carbonate mineral. Burbankite is one of many rare minerals that come from the famous mineral locality, Mont SaintHilaire, Quebec, Canada. Some specimens have been cut from there and in fact a large carat orange stone is the North American record holder for this species. But burbankite is far too rare to be considered a mainstream gemstone. Its ...

In the present study, ceriumdoped (01 mol%) strontium borophosphate (SBP) glasses were prepared through the melt quenching method. The structural and thermal properties of the glasses were ...

Isolation of strontium90, yttrium90, promethium147, and cerium144 from wet ashed urine by calcium oxalate coprecipitation and sequential solvent extraction

Asite substituted cerium orthovanadates, Ce1xSrxVO4, were synthesised by solidstate reactions It was found that the solid solution limit in Ce1xSrxVO4 is at x = 0 175. The crystal structure was analysed by Xray diffraction and it exhibits a tetragonal zircon structure of space group I4(1)/amd (1 4 1) with a = 7 3670 (3) and c = (1) angstrom for Ce0 825Sr0 175VO4 The UVvis ...

 · Rare earth elements are widely found in many minerals, some of which, such as bastnaesite, monazite, and xenotime, are of great commercial value. Cerium (Ce) is the rare earth element with the highest content in light rare earth ore. Solvent extraction is the most effective and efficient method to recover and separate Ce from other light rare earth elements.

Structure and conductivity of strontiumdoped cerium orthovanadates Ce1 xSrxVO4 (0 ) By Christophe T. G. Petit, Rong Lan, Peter I. Cowin and Shanwen Tao. Cite . BibTex ; Full citation; Abstract.

 · Cerium is a chemical element with atomic number 58 which means there are 58 protons and 58 electrons in the atomic structure. The chemical symbol for Cerium is Ce. Cerium is a soft, ductile and silverywhite metal that tarnishes when exposed to air, and it is soft enough to be cut with a knife. Cerium is the second element in the lanthanide ...

Geochemistry of Cerium; Goldschmidt classifiion: Lithophile: Ce 4+ was one of the ions least depleted from the mantle in the formation of the crust.: Ce 3+ was one of the ions least depleted from the mantle in the formation of the crust.: Ce 4+ is enriched in CaAlrich inclusions in meteorites relative to the composition of the solar system.: Ce 3+ is enriched in CaAlrich inclusions in ...

The partition coefficients of palladium, uranium, plutonium, cerium, and strontium between liquid lead and zinc were measured from 650 to 765°. At 703°, a temperature of measurement common to ...

I. Initial Studies of Strontium, Technetium, Cesium, Barium, Cerium, and Europium CO O "2

Metal ions are widely present in flotation pulp. Metal ions change solution chemistry and mineral surface properties, consequently affecting mineral flotation. In this work, the effect of strontium ions on bastnaesite flotation with salicylhydroxamic acid (SHA) was investigated by microflotation tests, contact angle measurements, zetapotential measurements, and Xray photoelectron ...

Spectrophotometric Determination of Cerium in Some Ore in Kurdistan Region – Iraq Ahmed M. Abdulla*, Omed I. Haidar** Department of Chemistry, Faculty of Science and Eduional Sciences, University of Sulaimani, Kurdistan region, Iraq Abstract A simple and Sensitive Spectrophotometric method was observed for trace measurement of Cerium (IV) in different serpentinite rocks in two .

Cerium activated strontiummagnesium orthophosphate phosphor exhibits strong UV luminescence whereas ceriummanganese activated phosphor shows pink luminescence. These phosphors could be used for the manufacture of eritemal or copy machine lamps and for fluorescent lamps for luminous signs, respectively. Samples of (Sr 1 x Mg x ) 3 (PO 4 ) 2 :Ce and (Sr 1 x Mg x ) 3 (PO 4 ) 2 :Ce, Mn ...
