Zirconium oxide （ZrO：） and boron carbide （B4C） were added to ZrB2 raw powders to prepare ZrB2 porous ceramics by reactive spark plasma sintering （RSPS）. The reactions between ZrO2 and B,C which produce ZrB2 and gas （such as CO and B2O3） result in pore formation. X-Ray Diffraction results indicated that the products phase was ZrB2 and the reaction was completed after the RSPS process. The porosity could be controlled by changing the ratio of synthesized ZrB2 to raw ZrB2 powders. The porosity of porous ceramics with 20 wt% and 40 wt% synthsized ZrB2 are 0.185 and 0.222, respectivly. And dense ZrB：SiC ceramic with a porosity of 0.057 was prepared under the same conditions for comparison. The pores were homogeneously distributed within the microstructure of the porous ceramics. The results indicate a promising method for preparing porous ZrB：based ceramics.

Antiferroelectrics exhibit unique double-hysteresis polarization loops, which have garnered significant attention due to their potential applications such as energy storage, electromechanical transduction, as well as synapse devices. However, numerous antiferroelectric materials have been reported to display signs of hysteresis loops resembling those of ferroelectric materials, and a comprehensive understanding remains elusive. In this work, we provide a phenomenological model that reproduces such widely observed artificial ferroelectric hysteresis with a superposition of numerous disordered antiferroelectric loops that have varying antiferroelectric-to-ferroelectric transition fields, particularly when these field ranges intersect. Experimentally, we realized such artificial ferroelectric-like hysteresis loops in the prototypical antiferroelectric PbZrO₃ and PbHfO₃ thin films, by introducing non-uniform local disorder (e.g., defects) via fine-tuning of the film growth condition. These ferroelectric-like states are capable of persisting for several hours prior to transitioning back into the thermodynamically stable antiferroelectric ground state. Those results provide insights into the fundamental impact of disorder on the AFE properties and new possibilities of disorder-tailored functions. © 2025 Acta Materialia Inc.

Poly (ionic liquid) (PIL) has emerged as a promising polymer substrate for solid electrolytes in lithium metal batteries due to its high ionic selectivity, excellent thermal stability, and compatibility with in situ polymerization processes. However, the limited ionic conductivity of PIL, primarily attributed to its restricted free volume and rigid polymer segments at room temperature, poses a significant challenge to its broader application on solid-state batteries. Herein, poly(1,3-dioxolane) (PDOL) is incorporated into PIL as a high-ionic-conductivity component to fabricate a semi-interpenetrating double network quasi-solid electrolyte (SIDN-QSE). The introduction of PDOL soft chains markedly improves the ionic conductivity of PIL-based quasi-solid electrolytes while preserving the advantageous properties of PIL, including its mechanical strength and thermal stability. Furthermore, the precursor containing ionic liquid with high dielectric constant induces the formation of the anions gathering inner Helmholtz plane (IHP) nearing the surface of the cathode, followed by the construction of the artificial cathode interface through the pre-reduction process. As a result, LiFeO4|SIDN-QSE|Li batteries achieve a high capacity retention of 70.4% after 700 cycles at 2 C and 30°C. Additionally, pouch cells incorporating the SIDN-QSE demonstrate excellent safety performance, withstanding mechanical stress tests such as bending, cutting, and piercing without compromising functionality. © 2025, The Authors.

High density Gd2O3–GdF3–Al2O3–B2O3–SiO2–CeF3 (GFOx) glass scintillators with different dimensions were synthesized. The glasses have a ∼75 % transmittance in visible range with a cut off wavelength of 373 nm. With the dimension increases, the energy transfer efficiency of GFOx glasses decreases from 77.0 % to 28.3 %. And the photoluminescence quantum yield (PL QY) of all glasses exceeds 56 % with a maximum of 68.4 %. GFOx glass scintillators exhibit a X–ray excitation luminescence (XEL) spectrum in 300–600 nm, and the XEL intensity decreases with increasing dimension. Under γ–ray excitation, a scattering model was established based on the light yield and aspect ratio of the glasses. The accuracy of the model was verified by measurement of commercial BGO crystal. In GFOx glass scintillator system, the intrinsic light yield of at 10 mm thickness is 1318 ph/MeV, while light loss coefficient is −0.12. With the aspect ratio increases, the formation and transport efficiency of excitons improve due to a larger surface area and more interfaces, resulting in a faster rise time. Meanwhile, all glasses exhibit a double exponential decay, including a fast component (∼100 ns) and a slow component (∼520 ns), and shows same trend as the rise time. In addition, the photon collection efficiency of SiPM coupled with the glasses decreased from 96.2 % to 31.8 %. Because the scattered photons can hardly reach the SiPM due to poor actual light attenuation length. © 2025

The study on the properties of barium carbonate in different crystal systems is play an important role for the evolution of electronic products requiring miniaturization and high performance. Here, the electrical and optical properties of BaTiO3 crystal structures with three space groups (Pm 3 m, P4mm, and P4/mmm) were systematically studied using the first-principles method. The structural are confirmed to be stable by the Born criterion The evolution energy band structures under HSE06 functional were more consistent with other theoretical and experimental results compared to the PBE functional. The band gaps of BaTiO3 for Pm 3 m, P4mm, and P4/mmm space groups up to 3.42, 3.24, and 3.26 eV and exhibit indirect semiconductor behavior. The optical parameters show that the light absorption rate and loss function of all three BaTiO3 were almost zero in the lower energy range. However, the tetragonal phase BaTiO3 with P4/mmm space group has a lower light reflection rate and higher light refractive index compared to the tetragonal phase BaTiO3 with P4/mmm and the cubic phase BaTiO3 with Pm 3 m space group, indicating its potential application value in electro-optic modulation. © 2024 SPIE.
