Photoluminescence properties of double perovskite Ca2LuTaO6:Bi3+/Sm3+ white light emitting phosphors Ceram. Int. (IF 5.2) Pub Date : 2024-03-08 Noor Zamin Khan, Sayed Ali Khan, Weilong Chen, Abdul Jalil, Jahangeer Ahmed, Muhammad Amin Padhiar, Chen Li, Marcin Runowski, Ren-Kui Zheng
The high-temperature solid state reaction approach was used to successfully synthesize novel tunable-color emitting CaLuTaO phosphors with double perovskite structure that were un-doped, single-doped, and co-doped with Bi/Sm ions. The crystal structure, microstructure, steady-state photoluminescence, time-resolved luminescence measurements, and thermal quenching features of the material were studied

Energy-storage performance of NaNbO3-based ceramic capacitor derived from a high DOP glass network structure Ceram. Int. (IF 5.2) Pub Date : 2024-03-08 Yuxin Hao, Yongping Pu, Jinbo Zhang, Xin Peng, Yangchao Shang, Haochen Xie, Lei Zhang, Bo Wang, Xuqing Zhang
0.75(0.4NaO-0.1KO-0.5NbO)-0.25(0.87SiO-0.13BaO) glass-ceramics were prepared by a traditional melting method to optimize the crystallization kinetics. We obtained a glass network with high degree of polymerization (DOP) by crystallization at different temperatures and achieved a high energy storage density. The increase of crystallization temperature has promoted the precipitation of ferroelectric

Fused deposition modeling of glass sealants: A new approach to SOFC sealing Ceram. Int. (IF 5.2) Pub Date : 2024-03-08 I.V. Tolstobrov, E.S. Shirokova, A.I. Vepreva, D. Yu Dubovtsev, YuA. Chetvertnykh, A.V. Kuzmin, N.S. Saetova
Although various additive manufacturing techniques are used intensively to mold materials for solid oxide fuel cell (SOFC) applications, 3D printing has not been applied to obtain sealants which are crucial components for SOFC stacking. It is essential to develop different methods for molding sealing products based on glasses and glass-ceramics which are the most promising materials for SOFC stacking

Optics, structures and luminescent properties in Dy3+-doped tellurite glass regulated by Nb2O5 Ceram. Int. (IF 5.2) Pub Date : 2024-03-07 Zelin He, Jiaming Zhang, Dechun Zhou, Tong Wu, Yuxiao Wu
In this work,60TeO-(35-x)ZnO-xNbO–5SrF-0.5DyO glasses was prepared to use a high-temperature melting method, where x represents the NbO content (x = 0,5,7.5,10).Raman spectra studies revealed that increasing the concentration ratio of NbO to TeO resulted in the gradual transformation of [TeO] and [TeO] units in the glass network to [TeO] units. This transformation also enhanced the stability of the

Sc-doped Ba0.5Sr0.5Co0.8Fe0.2O3-δ cathodes for protonic ceramic fuel cells Ceram. Int. (IF 5.2) Pub Date : 2024-03-07 Xin Yang, Zizhuo Wang, Guoqiang Li, Yue Zhou, Chongzheng Sun, Lei Bi
Sc is used as a dopant to tailor the traditional BaSrCoFeO (BSCF) cathode for protonic ceramic fuel cells (PCFCs). Experiments and first-principles calculations are used in this study to explore the influence of Sc-doping on the performance of BSCF cathodes for PCFCs. Sc can only occupy the Co or Fe sites, and doping Sc at the Ba or Sr sites results in the formation of secondary phases. The use of

Synthesis and characterisations of clinoptilolite enriched hydroxyapatite nanoceramics by sol-gel route for bone regeneration Ceram. Int. (IF 5.2) Pub Date : 2024-03-07 Esma Daldiken, Fatma Zehra Koçak, Nilüfer Küçükdeveci
Hydroxyapatite (HA) has great bioactive potential in bone tissue engineering (BTE). However, the high crystalline stability of synthetic HA restricts its bioresorbability which extends the healing time of bone defects. This study investigates doping HA with biocompatible Clinoptilolite (CLP) mineral rich in silicate and other biomimetic ions (Na, K, Ca, Mg etc.). Sol-gel-based CLP doped HA nanoceramics
