The aim of this work is to determine the structural and optical properties of Eu-doped ZnO powders prepared by supercritical antisolvent precipitation route(SAS)and to correlate the physico-chemical features with the photocatalytic activity under UV *** and EPR spectroscopy highlight the introduction of novel defects(mainly singly and doubly ionized oxygen vacancies,and oxygen interstitials)on the Eu-doped ZnO samples,which confer higher hydrophilicity to the doped samples with respect to bare ZnO,as evidenced by FT-IR ***,photoluminescence spectra show that the presence of Eu^(3+) totally quenches the visible light emission typical of bare ZnO,which mainly results from the recombination of photogenerated holes at defective *** prepared samples were tested both for the photocatalytic degradation of crystal violet dye(CV)and for the partial oxidation of ferulic acid under UV *** photocatalytic activity results evidence of a higher ability of Eu-doped photocatalysts to degrade CV and ferulic acid,while higher selectivity values towards vanillin are obtained in the presence of bare *** higher activity of Eu-doped ZnO photocatalysts is linked to the stabilization of photogenerated holes and to their higher hydrophilicity,both brought by the generation of defective sites induced by the presence of Eu^(3+) ions within the ZnO lattice.

Text categorization plays an important role in data mining. Feature selection is the most important process of text categorization. Focused on feature selection, we present an improved text frequency method for filtering of low frequency features to deal with the data preprocessing, propose an improved mutual information algorithm for feature selection, and develop an improved *** method for characteristic weights evaluation. The proposed method is applied to the benchmark test set Reuters-21578 Top10 to examine its effectiveness. Numerical results show that the precision, the recall and the value of F1 of the proposed method are all superior to those of existing conventional methods.

The structural, vibrational and impedance analysis for(Zn O)1 x(Sb2O3)xcomposite synthesized by solid state reaction technique were carried out in the present investigation. X-ray diffraction(XRD) study showed that(Zn O)1 x(Sb2O3)xcomposite has hexagonal(wurtzite) crystal structure. Variation in lattice constants with Sb-doping indicated the proper incorporation of Sb dopant in Zn O host matrix. The results of Raman spectroscopy test suggested the signature of E2(high) and E1(TO) Raman modes, and verified the wurtzite structure of(Zn O)1 x(Sb2O3)x composite. Two additional phonon bands(671, 712) cm 1appeared in Raman spectra of composite samples due to the existence of the lattice defects caused by Sb doping or may be other intrinsic lattice defects formed during the synthesis of(Zn O)1 x(Sb2O3)xcomposite. The frequency dependent on the electrical characteristics, such as, impedance(Z), dielectric constant(ε) and AC conductivity(σ) have been studied in a range of frequencies for different Sb concentration at room temperature. The electrical measurement results showed that the impedance increased with Sb dopant concentration, while dielectric constant and AC conductivity decreased with Sb dopant concentration.

Single-photon entanglement is a peculiar type of entanglement in which two or more degrees of freedom of a single photon are correlated quantum-mechanically. Here, we demonstrate a photonic integrated chip able to generate and manipulate single-photon path-entangled states, using a commercial red LED as light source.A Bell test, in the Clauser, Horne, Shimony, and Holt(CHSH) form, is performed to confirm the presence of entanglement, resulting in a maximum value of the CHSH correlation parameter equal to 2.605 ± *** allows us to use it as an integrated semi-device independent quantum random number generator able to produce certified random numbers. The certification scheme is based on a Bell’s inequality violation and on a partial characterization of the experimental setup, without the need of introducing any further assumptions either on the input state or on the particular form of the measurement observables. In the end a min-entropy of 33% is demonstrated.
