The exposure of pyroelectric crystals to a heating cycle in near-vacuum conditions has been shown to be a viable method of producing x-rays. The z-negative face of the crystal forms a positive charge as the crystal heats, and a negative charge as it cools. The opposite is true for the z-positive face. Literature has shown that this charge is great enough to accelerate electrons to energies of u...

New hetero-binuclear Hg-Cu Schiff base complexes were prepared by reaction of 2,2'-[1,1'-(2,2-‎dimethylpropane-1,3-diyldinitrilo)-diethyldyne]diphenolato}copper(II) (CuL1) and 6,6'-X-2,2'-[(2,2-‎dimethylpropane-1,3-diyl)bis(nitrilomethanylylidene)]diphenolato copper(II) [(X = ethoxy (CuL2) and ‎methoxy (CuL3)], with HgCl2 to give [Cu(L1)HgCl2] (1), [Cu(L2)HgCl2] (2), and [Cu(L3)HgCl2] (3), ‎res...

sr6nb10o30–nb2o5 nanocomposite was synthesized in 2m naoh aqueous solution. a stoichiometric 1:1 sr:nb molar ratio hydrothermal method at 120°c was used to synthesize this nanocomposite. sr(no3)2 and nb2o5 were used as raw materials. the synthesized nanomaterials were characterized by powder x-ray diffraction (pxrd) technique. it was found that sr6nb10o30 was crystallized in tetragonal crystal ...

The perovskite-type oxides strontium-substituted lanthanum nickelate (LSNO) were prepared by a coprecipitation method in the present of octanoic acid as surfactant. The phase composition, morphology,lattice parameters and size of nanoparticles in these materials were characterized through Fourier transform infr...

Four liquid crystal compounds of the form, 2-Sec-butyl-4-[(4-x-phenyl) diazenyl) phenyl-4-(octadecyloxy] benzoate symbolized as I18a, I18b, I18c and I18d were prepared in which the substituent (X) was taken CH3O-, CH3-, Br- and -NO2 respectively. Characterization of prepared compounds is done using FT-IR, 1H-NMR, Mass Spectroscopy and Elemental Analysis.. Their mesophase behavior was investigat...
