Crystal growth, structure and physical properties of crystals

Vesuvianite is an ortho-diorthosilicate of a general schematic formula X~19Y13Z18O68W10, where X – Ca and other cations, which occupy sites of coordination number 8, Y – cations occupying octahedrons and pentagonal polyhedrons: Al, Fe, Mg, Ti, etc., Z – Si in tetrahedrons, W – univalent and bivalent anions. Structures of vesuvianites are studied in dependence on a character of cation ordering i...

Growth, Mechanical, Thermal and Spectral Properties of Cr3+∶MgMoO4 Crystal

This paper reports the growth, mechanical, thermal and spectral properties of Cr(3+):MgMoO(4) crystals. The Cr(3+):MgMoO(4) crystals with dimensions up to 30 mm×18 mm×14 mm were obtained by TSSG method. The absorption cross-sections of (4)A(2)→(4)T(1) and (4)A(2)→(4)T(2) transitions are 12.94×10(-20) cm(2) at 493 nm and 7.89×10(-20) cm(2) at 705 nm for E//N(g), respectively. The Cr(3+):MgMoO(4)...

Determination of Crystal Growth Rate and Morphology of Barium Carbonate Crystals in a Semi-batch Crystallizer

A semi-batch crystallization system is used to determine growth kinetics and morphology of barium carbonate crystals, under a constant pH value and constant temperature in the various relative supersaturations. Results show that crystal growth rate satisfies a first-order kinetic expression at high relative supersaturation, while at relative supersaturation values lower than 3,  the k...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

Ni2As2O7 pyrochlore nanomaterial: Solid state synthesis, crystal structure determination, crystal phase growth study and physical properties

Nanostructured Ni2As2O7 semiconductor samples were synthesized by a solid state method among As2O3 and Ni(NO3)2.6H2O raw materials at 650 °C (S1) and 750 °C (S2) as reaction temperatures. The synthesized nanomaterials were characterized by powder X-ray diffraction (PXRD) technique and F...
