Scandium fluorides
(1997-11-14)
A new modification of scandium fluoride has been synthesised. The compound is deficient in fluorine, with the composition ScF2.76. It belongs to the tetragonal system, lattice parameters being a = 3.792 and c = 6.740 Å and ...
Luminescent properties of some rare earth phosphates
(Gordon Breach Sci Publ Ltd, 1996-01-01)
Luminescent properties of scandium and yttrium phosphates are discussed and mechanisms involving their emissions proposed.
Photocatalytic decomposition of rhodamine-B using scandium and silver-modified TiO2 Powders
(2014)
Semiconductor-mediated photocatalytic oxidation is an interesting method for water decontamination and a specially modified TiO2 is said to be a promising material. This study verified that the synthesis of 1wt%Ag ...

(2014)
Semiconductor-mediated photocatalytic oxidation is an interesting method for water decontamination and a specially modified TiO2 is said to be a promising material. This study verified that the synthesis of 1wt%Ag ...
Scandium fluorophosphate glasses: a structural approach
(Elsevier B.V., 2002-12-01)
A systematic investigation on glass formation in the ternary system InF3-BaF2-[Sc(PO3)(3)](n) has been carried out. Scandium polyphosphate [Sc(PO3)(3)](n) has been used as a third component in order to investigate the ...
Effects of substituting ytterbium for scandium on the microstructure and age-hardening behaviour of Al-Sc alloy
(Elsevier B.V., 2014-04-17)
In order to reduce the cost of Al-Sc alloys and maintain their mechanical properties, the microstructure and mechanical properties of Al-0.24 wt% Sc-0.07 wt% Yb in comparison with Al-0.28 wt% Sc alloys were studied. The ...
Determination of scandium in acid mine drainage by ICP-OES with flow injection on-line preconcentration using oxidized multiwalled carbon nanotubes
(Elsevier, 2014-11)
An on-line scandium preconcentration and determination system implemented with inductively coupled plasma optical emission spectrometry associated with flow injection was studied. Trace amounts of scandium were preconcentrated ...
Synthesis and characterization of β-RbSc(CrO4)2
(1995-07-01)
Synthesis and crystallographic data are reported for the double rubidium-scandium chromate RbSc(CrO4)2. The parameters of the orthorhombic cell are a = 14.836(2) A ̊; b = 5.627(1) A ̊ and c = 8.835(4) A ̊, Z = 4. The ...
Erbium, chromium : yttrium scandium gallium garnet laser for caries removal: influence on bonding of a self-etching adhesive system
(SPRINGER LONDON LTD, 2008)
This study evaluated the influence of the dental substrates obtained after the use of different caries removal techniques on bonding of a self-etching system. Forty, extracted, carious, human molars were ground to expose ...
Trace elements, rare earth elements and scandium concentration in a weathering profile of metaultramafic rock (Bom Jesus da Penha, Minas Gerais, Brazil)Concentração de elementos traços, terras raras e escândio em perfil de intemperismo de rocha metaultramáfica (Bom Jesus da Penha, Minas Gerais)
(2018-07-24)
The development of lateritic horizons is responsible for chemical and mineralogical reorganization in the parent rock. The final arrangement is controlled by the primary composition of the parent material, climate conditions, ...
