The xBa0.8Ca0.2TiO3-(1 − x)NiCuZn ferrite (x = 0.1, 0.3, 0.5, 0.7, and 0.9) nanocomposites were prepared by using sol-gel method. The densification of these composites was carried out using microwave sintering method. The magnetic field induced changes in the ferroelectric polarization loop may support the possible magnetoelectric coupling between Ba0.8Ca0.2TiO3 and NiCuZn ferrite phases. The observed change in ferroelectric polarization with applied magnetic field proves the coupling between magnetic and ferroelectric order parameters. The loop change is observed with the composition and with magnetic field. The magnetoelectric coefficient of the nanocomposite with x = 0.3 shows a value of 280 mV/cm Oe is obtained.

The valence of rare earth ions in R2MgSi2O7:Eu, Dy (R = Ca, Sr) long‐afterglow phosphors was studies by L3 edge X‐ray absorption near‐edge structure (XANES) spectroscopy and photoluminescence spectroscopy. The results suggest that Eu ions are in a divalent and trivalent mixed‐valence state while Dy ions exist in the trivalent state. No monovalent Eu and tetravalent Dy were observed. The applicability of a hole‐transferring mechanism of long‐afterglow phosphors is discussed. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

This article describes a new application of graphene oxide (GO) in CE based on the coating of fused silica capillary for chiral separation. The coated capillary was characterized by SEM, energy dispersive X-ray spectroscopy, and Raman spectra. The results indicated that the capillary was coated with GO. Chiral separations were carried out in the GO-coated capillary for the ephedrine-pseudoephedrine (E-PE) isomers and β-methylphenethylamine (β-Me-PEA) isomers at the optimal buffer conditions without any chiral selector by CE. The precision and reproducibility of GO-coated capillary were investigated, and the RSDs of migration time (n = 6) for the E-PE isomers were 1.35-1.41%, and 0.97-3.50% for β-Me-PEA isomers, respectively. The LOD for E-PE isomers and β-Me-PEA isomers was 3 μM and 18 μM, respectively.
