| 2 | Enhanced dielectric and electrocaloric properties in lead-free rod-like BCZT ceramics显示文摘Ba0.85Ca0.15Zr0.10Ti0.90O3(BCZT)lead-free ceramics demonstrated excellent dielectric,ferroelectric,and piezoelectric properties at the morphotropic phase boundary(MPB).So far,to study the effect of morphological changes on dielectric and ferroelectric properties in lead-free BCZT ceramics,researchers have mostly focused on the influence of spherical grain shape change.In this study,BCZT ceramics with rod-like grains and aspect ratio of about 10 were synthesized by surfactant-assisted solvothermal route.X-ray diffraction(XRD)and selected area electron diffraction(SAED)performed at room temperature confirm the crystallization of pure perovskite with tetragonal symmetry.Scanning electron microscopy(SEM)image showed that BCZT ceramics have kept the 1D rod-like grains with an average aspect ratio of about 4.Rod-like BCZT ceramics exhibit enhanced dielectric ferroelectric(εr=11,906,tanδ=0.014,Pr=6.01μC/cm^2,and Ec=2.46 kV/cm),and electrocaloric properties(ΔT=0.492 K andz=0.289(K×mm)/kV at 17 kV/cm)with respect to spherical BCZT ceramics.Therefore,rod-like BCZT lead-free ceramics have good potential to be used in solid-state refrigeration technology. | Zouhair HANANI Soukaina MERSELMIZ Abdelaadim DANINE Nicolas STEIN Daoud MEZZANE M’barek AMJOUD Mohammed LAHCINI Yaovi GAGOU Matjaz SPREITZER Damjan VENGUST Zdravko KUTNJAK Mimoun El MARSSI Igor ALUK'YANCHUK Mohamed GOUNE | 2020 | Journal of Advanced Ceramics2020，9，2： | 1 |

| 13 | Effect of rare earth on physical properties of Na_(0.5)Bi_(0.5)TiO_(3)system:A density functional theory investigation显示文摘Na_(0.5)(Bi_(3/4)RE_(1/4))_(0.5)TiO_(3)(RENBT,RE=Nd,Gd,Dy,and Ho)compounds were investigated in the framework of first-principles calculations using the full potential linearized augmented plane wave(FP-LAPW)method based on the spin-polarized density functional theory implemented in the WIEN2k code.Combined charge density distribution and Ti K-edge X-ray absorption spectra reveal that the RENBT compositions with high polarization values are accompanied by a higher TiO_(6)distortion,DyNBT,and NdNBT compounds.The effect of the rare-earth elements on the polarization is confirmed experimentally with the collection of the hysteresis loops.The investigation of the electronic properties of the compounds highlights the emergence of a magnetization owing to the 4f orbital effect of the rare-earth elements.Besides,the investigation of the chemical ordering shows a short-range chemical ordering for the pure composition and an increased A-site disorder for dysprosium doped NBT system.The increased disorder may speak for increased relaxor properties in the RE doped compositions. | Manal Benyoussef Halima Zaari Jamal Belhadi Youssef El Amraoui Hamid Ez-Zahraouy Abdelilah Lahmar Mimoun El Marssi | 2022 | Journal of Rare Earths2022，40，3： | 0 |
| 14 | Novel lead-free BCZT-based ceramic with thermally-stable recovered energy density and increased energy storage efficiency显示文摘The eco-responsible lead-free piezoelectric ceramics have been intensively searched for more than adecade, however, the final goal to replace toxic ceramics like lead zirconate titanate (PZT) with lead-freecompounds, having comparable or even better performance has not yet been reached. In this road, thelead-free ceramics Ba_(0.85)Ca_(0.15)Zr_(0.1)Ti_(0.9)O_(3) (BCZT), possessing excellent dielectric, ferroelectric, andpiezoelectric properties are regarded as serious candidates for the PZT replacement. Besides, nano-structuring BCZT is of paramount importance to enhance these functionalities even more. Here, BCZTmultipodes are designed by template-growth hydrothermal synthesis using hydrogen zirconate titanatenanowires. We demonstrate that the fabricated BCZT multipodes exhibit high dielectric permittivity of5300 with a temperature stability coefficient of ±5.9% between 20 and 140℃. A significant recoveredenergy density of 315.0 mJ/cm^(3) with high thermal stability and high energy storage efficiency of 87.4%,and enhanced large-signal piezoelectric coefficient d^(*)_(33) (310 pm/V) are found. Compared to the tradi-tional BCZT ceramics reported in the literature, relying on high-temperature processing, our sampleexhibits boosted energy storage parameters at a much lower temperature. These outcomes may offer anew strategy to tailor eco-responsible relaxor ferroelectrics toward superior energy storage performancefor ceramic capacitor applications. | Zouhair Hanani Soukaina Merselmiz M'barek Amjoud Daoud Mezzane Mohammed Lahcini Jaafar Ghanbaja Matjaz Spreitzer Damjan Vengust Mimoun El Marssi Igor A.Luk'yanchuk Zdravko Kutnjak Brigita Rozic Mohamed Goune | 2022 | Journal of Materiomics2022，8，4： | 0 |
| 15 | Growth,Structural and Optical Characterization of Se_(75)Te_(17)Ge_8 Thin Films显示文摘Se75Te17Ge8 thin film was processed on glass substrates by a pulsed laser deposition technique. The ceramic target used for the deposition was prepared by a solid state sintering method in a vacuum sealed silica tube. The structural characterization was investigated by X-ray diffraction coupled with energy-dispersive X-ray spectrometry. The optical parameters were determined from the transmittance and reflectance spectra of the prepared film. The Wemple and Di Domenico models both were appropriate to describe the experimental results. The optical absorption coefficient was analyzed to identify the type of the optical transition and determine the corresponding energy values. | SALIM S M LAHMAR A ZAYIED H SALEM A M SAKR G B BARROY P TELEB N EL MARSSI M | 2015 | Journal of the Chinese Ceramic Society2015，，2： | 0 |
