Analysis of the elastic anisotropy of titanium sheet showed that, after plastic deformation in rolling, titanium grains are oriented in such a way that parallel to the rolling plane is a crystal plane inclined at 32 ° to the direction of rolling. 相似文献

(1 − x)PbFe1/2Nb1/2O3−x
PbTiO3 (PFN-xPT) ferroelectric ceramics with low dielectric loss and pronounced anomalies of dielectric and pyroelectric properties near
the ferroelectric-ferroelectric phase transition was obtained by doping with lithium. The temperature dependence of the position
of the morphotropic boundary between the rhombohedral (monoclinic) and tetragonal phases in the x-T phase diagram of the PFN-xPT system was determined for the first time. 相似文献

Samples of BaTiO3/(Ba1 ? x Sr x )TiO3 (BT/BST-x) superlattices have been studied using X-ray diffraction analysis. A complete parallel orientation of all the studied films and the substrate has been revealed, and the modulation periods ?? of the superlattices, the parameters of the unit cell averaged over the ?? period, and the parameters of individual components of the superlattices have been determined. 相似文献

The structure of four new palladium complexes [Pd(HL 2 )Cl 2 and Pd(L 1–3 ) 2 ] with 3-(2-pyridyl)-5-R-1,2,4-triazoles (R=H, CH3, Ph respectively HL 1 , HL 2 , HL 3 ) was proposed based on IR, NMR, UV spectroscopy and MALDI mass spectrometry data analysis. It is found that the complexation of HL 2 and HL 3 with Pd2+ ions results in a decrease of their fluorescence intensity and it is vice versa in case of HL 1 . Furthermore, the influence of the substituent (R) in the 3-(2-pirydyl)-5-R-1,2,4-triazoles on the fluorescent and protolytic properties of HL 1–3 was investigated. 相似文献

An approach was proposed to analyzing platinum-containing materials. It involves the high-temperature dissolution of samples in acids under the action of microwave radiation, the sorption preconcentration of noble metals on complexing adsorbents, and their instrumental determination after the microwave dissolution of the concentrate.__________Translated from Zhurnal Analiticheskoi Khimii, Vol. 60, No. 5, 2005, pp. 536–541.Original Russian Text Copyright © 2005 by Kubrakova, Myasoedova, Shumskaya, Kudinova, Zakharchenko, Mokhodoeva. 相似文献

The enzymogel nanoparticle made of a magnetic core and polymer brush shell demonstrates a novel type of remote controlled phase‐boundary biocatalysis that involves remotely directed binding to and engulfing insoluble substrates, high mobility, and stability of the catalytic centers. The mobile enzymes reside in the polymer brush scaffold and shuttle between the enzymogel interior and surface of the engulfed substrate in the bioconversion process. Biocatalytic activity of the mobile enzymes is preserved in the enzymogel while the brush‐like architecture favors the efficient interfacial interaction when the enzymogel spreads over the substrate and extends substantially the reaction area as compared with rigid particles. 相似文献

To estimate the signal narrow-bandedness in signal theory, we propose integral constraints instead of local ones. The examples presented demonstrate the advantages of this criterion. 相似文献
