Bismuth sodium titanate (BNT)-based piezoelectric materials are the most promising candidates for lead-free actuator applications. With the request for integration and size miniaturization of devices, it is urgent to develop thin films for microdevices to be compatible with semiconductor processes. Through composition engineering, BNT-based thin films were fabricated on silicon substrates, with ultra-high strain response and negligible hysteresis in strain curves. The DC-dependent and temperature-dependent dielectric properties were collected to investigate the relaxor state of thin films. The structure and polarization transition and evolution as a function of electric field and time were analyzed based on the electric characterization, in-situ Raman measurements, and dynamics PFM. The reversible phase transition and polarization order-disorder transformation are the most significant features for reaching a large strain of >1.6% in BNT-based thin films.

Doping and substitution methods are predominantly employed in the synthesis of ceramics to achieve their desired functional properties. We studied the behavior of excessive dopants in addition to an existing stoichiometric composition using a high-throughput continuous compositional spread sputtering method. We paid attention to the possible formation of thermodynamically unstable phases by the addition of an excessive amount of dopants. We showed that even when dopants were added as an additive, they dissolved into the existing lattice due to the benefit of the entropy of mixing. Regardless of excessiveness, all added elements incorporated into the lattice, stabilized by the tolerance factor. We also demonstrated our findings exemplarily with lead iron niobate to induce magnetic properties alongside inherent ferroelectricity (MS = 10 emu/cm3, PS = 16 μC/cm2). We compare the results from CCS with those from the non-additive solid-state method, leading to a conclusion that the benefit from the entropy of mixing allows foreign elements to substitute for the elements initially residing in the lattice to a degree in compliance with the Goldschmidt tolerance factor. This observation was confirmed by a density functional theory calculation. We anticipate that our study could necessitate intensive research on achieving desired composition through industry-friendly processing.

The encapsulation of metal-based phase change materials using ceramics can realize safe and effective storage of high-temperature thermal energy. However, the use of a low toughness ceramic shell around the microcapsules cannot ensure the provision of a high latent heat and thermal cyclic stability. Here, we provide a new and effective design strategy for preparing biomimetic Al–Si microcapsules that are based on a sea-shell corrugated structure and a nano-scale corundum-mullite composite shell. The latent heat of the microcapsules was over 400 J/g, much greater than other metal-based microcapsules reported to date. The unique biomimetic-corrugated structure microcapsules obtained by a heat treatment at 1000 °C exhibited excellent thermal stability, achieving near zero heat loss after 5000 thermal cycles, whose latent heat of absorption and release reached up to 448.3 J/g and 451.8 J/g respectively. Furthermore, the microcapsules possessed a giant heat storage density of 945.8 J/g within 300–700 °C, and the performance figure of merit was 6384.2 × 106 J2·K−1·s−1·m−4, approximately 15 times higher than that of commercial solar salt. This new approach provides a pathway the practical application of Al–Si alloys as thermal storage materials for renewable energy applications.

In recent years, potassium tantalum niobate (KTN) electro-optical deflection devices have gained considerable attention because of their notable advantages, such as large deflection angles, low operational voltage requirements, and compact dimensions. This study uses the phase-shifted interferometric optical path to characterize the influence of direct current (DC) voltage on charge density. An interferogram is acquired using the four-step phase-shifting technique, enabling the calculation of phase delays and deducing the variation in charge density. Experimental results demonstrate that the charge density near the cathode increases with an increase in DC voltage. Subsequently, we utilize the frequency dependence of the dielectric constant of the KTN crystal on the electric field. The dielectric constant can be enhanced when the characteristic frequency of the motion of the polar nanoscale region matches the frequency of the electric field. This field-induced enhancement effect improves the beam deflection performance of the KTN crystal. Application requirements in the field of high-speed random scanning can be realized through the mechanism of the KTN crystal co-acting with DC and alternating current electric fields.

A dual phase boride and carbide ceramic with the nominal composition (Ti0.2Zr0.2Hf0.2Nb0.2Ta0.2)B2 and (Ti0.2Zr0.2Hf0.2Nb0.2Ta0.2)C was prepared by reactive synthesis and consolidated by spark plasma sintering. The resulting microstructure contained about 30% (in volume) boride and 70% carbide. Compositional inhomogeneities were observed within single grains that had core-shell structures and preferential accumulation of specific metals in the boride or carbide phases. Specifically, Ti and Nb had higher concentrations in the boride, whereas Hf and Ta in the carbide. The Zr concentration was relatively equally distributed in the two phases. The dual phase ceramic had additional, distinctive features including nanosized inclusions, possibly related to local miscibility gaps and supersaturation, linear defects, and strain due to adjustment of the crystal structure. As a consequence, the fracture mode was transgranular with the crack path deviated by these nanometric microstructure alterations. Nanoindentation under 5 mN measured higher hardness and modulus for the boride, 30 GPa and 525 GPa, as compared to the carbide phase, 22 GPa and 425 GPa, due to a higher concentration of dislocation tangles and strains deriving from the introduction of metals with different sizes (and properties) in a less compliant hexagonal lattice.

The electrocaloric effect (ECE) offers a pathway to environmentally sustainable and easily miniaturized refrigeration technology, positioning it as a front-runner for the next generation of solid-state cooling solutions. This research unveils a remarkable ECE in a finely tuned (Ba0.86Ca0.14)0.98La0.02Ti0.92Sn0.08O3 ceramic, exhibiting a temperature shift (ΔT) of 1.6 K across more than 85% of the maximum ΔT (ΔTmax) and spanning an exceptionally wide operational range of 92 K. Our investigation on dielectric responses and ferroelectric polarization-electric field (P–E) loops suggests that the broad operational scope results from the fragmentation of extended ferroelectric domains into smaller domains and polar nano-regions (PNRs) supported by PFM analysis. Furthermore, the introduction of La enhances spontaneous polarization by significantly extending the maximum electric field that can be applied, facilitating high-performance ECE at ambient temperature. This study positions BaTiO3-based lead-free ceramic as a sustainable alternative for addressing the cooling demands of modern electronic components, marking a significant stride toward next-generation solid-state refrigeration.

Millimeter-wave and terahertz frequency bands are receiving more and more attention due to their big potentials for widespread applications such as in high-speed communications and high-resolution imaging. Nevertheless, limited by the functional materials and devices in these bands, we face lots of challenges towards high efficiency, high precision, and multi-domain electromagnetic manipulations that are urgently required in the practical application scenarios. The emergence of metasurfaces, especially the digital coding metasurfaces and programmable metasurfaces, has provided powerful capabilities to control electromagnetic waves. Recently, with the progress of space-domain, time-domain, space-time-domain, and polarization-domain programmable metasurfaces, considerable new applications have been achieved, including new-architecture wireless communication transmitters, the integration of sensing and communications, simultaneous information and power transfers, and information encryption. Consequently, integrated multifunctional platforms based on metasurfaces are expected.

Antiferroelectric materials represented by PbZrO3(PZO) have excellent energy storage performance and are expected to be candidates for dielectric capacitors. It remains a challenge to further enhance the effective energy storage density and efficiency of PZO-based antiferroelectric films through domain engineering. In this work, the effects of three variables, misfit strain between the thin film and substrate, defect dipoles doping, and film thickness, on the domain structure and energy storage performance of PZO-based antiferroelectric materials are comprehensively investigated via phase-field simulations. The results show that applying tensile strain to the films can effectively increase the transition electric field from antiferroelectric to ferroelectric. In addition, the introduction of defect dipoles while applying tensile strain can significantly reduce the hysteresis and improve energy storage efficiency. Ultimately, a recoverable energy density of 38.3 J/cm3 and an energy storage efficiency of about 89.4% can be realized at 1.5% tensile strain and 2% defect dipole concentration. Our work provides a new idea for the preparation of antiferroelectric thin films with high energy storage density and efficiency by domain engineering modulation.

A boom in exploration for marine geology and ocean resources has resulted in a huge demand for radio navigation or special environment communications, in turn spurring the rapid development of portable underwater wireless communication technology. State of the art acoustic communication methods used today are plagued by substantial transmission delays, multipath effects, and doppler frequency shifts, among other challenges, thus impeding the advancement of underwater wireless communication technology. Low-frequency electromagnetic transmission has proven to be a prospective solution for underwater communication, but the conventional electrical antennas is too large for portable underwater wireless communication. Emergent magnetoelectric (ME) antennas driven by piezoelectric materials have become a promising solution for miniaturizing very low frequency (VLF) communication systems. Here, a theoretical model between the radiation performance and piezoelectric material properties of the ME antenna was conducted. Guide by the theory analysis, Pb(In1/2Nb1/2)O3Pb(Mn1/3Sb2/3)O3Pb(Zr0.49Ti0.51)O3 (PIN-PMS-PZT) piezoelectric ceramic simultaneous with high d33 and Qm (d33 ∼ 401, Qm ∼ 1510) has been designed to enhance the magnetoelectric radiation of the VLF ME antenna. The PIN-PMS-PZT based ME antenna achieves a large converse magnetoelectric response 1.78 Gs⋅cm/V in EMR, which is almost doubled to commercial PZT based ME antenna.

海洋地质和海洋资源勘探的蓬勃发展导致了对无线电导航或特殊环境通信的巨大需求，进而推动了便携式水下无线通信技术的快速发展。目前使用的最先进的声学通信方法存在严重的传输延迟、多径效应和多普勒频移等问题，从而阻碍了水下无线通信技术的发展。低频电磁传输已被证明是一种前景广阔的水下通信解决方案，但传统的电子天线对于便携式水下无线通信来说过于庞大。由压电材料驱动的新兴磁电（ME）天线已成为极低频（VLF）通信系统小型化的一种有前途的解决方案。在此，我们对 ME 天线的辐射性能与压电材料特性之间的关系进行了理论建模。在理论分析的指导下，设计了同时具有高 d33 和 Qm（d33 ∼ 401，Qm ∼ 1510）的 Pb(In1/2Nb1/2)O3Pb(Mn1/3Sb2/3)O3Pb(Zr0.49Ti0.51)O3（PIN-PMS-PZT）压电陶瓷，以增强甚低频 ME 天线的磁电辐射。基于 PIN-PMS-PZT 的 ME 天线在 EMR 方面实现了 1.78 Gs⋅cm/V 的大反向磁电响应，几乎是基于 PZT 的商用 ME 天线的两倍。更重要的是，基于该 VLF 天线建立了一个 VLF 通信系统，该系统成功地利用移幅键控（ASK）调制传输了数字信号。相信这项研究成果能为未来 ME 天线的应用提供理论基础和可行的技术途径。

State of the art acoustic communication methods used today are plagued by substantial transmission delays, multipath effects, and doppler frequency shifts, among other challenges, thus impeding the advancement of underwater wireless communication technology. Low-frequency electromagnetic transmission has proven to be a prospective solution for underwater communication, but the conventional electrical antennas is too large for portable underwater wireless communication. Emergent magnetoelectric (ME) antennas driven by piezoelectric materials have become a promising solution for miniaturizing very low frequency (VLF) communication systems.

With the merits of both solid polymer electrolytes (SPEs) and inorganic ceramic electrolytes (ICEs), composite polymer electrolytes (CPEs) prepared by coupling polymer matrix with inorganic fillers are broadly utilized in solid lithium metal batteries (SLMBs). However, CPEs fabricated by a single filler with polymer matrix often exhibit unsatisfactory performance. Here, prepared by coupling poly (ethylene oxide) (PEO) matrix with a natural additive carboxymethyl cellulose lithium (CMC-Li) and an inorganic filler mineral hectorite (Ht), an efficient CPE is reported. Detailedly, CMC-Li is considered to act as a “bridge”, which connects the Ht nanosheets distributed in PEO, thus establishing continuous Li+ transmission channels. Ht with a nanolayers structure vividly acts as “bricks”, pave the way for ion transference. In addition, oxygen atoms in CMC-Li contribute to adequately dissociating lithium salts, hydrogen bonding generated by hydroxyl groups is propitious to anchor anions to increase the Li+ transference number. Under the synergistic effect brought by CMC-Li and Ht, the electrolyte membrane PEO-10%Ht-4%CMC-Li (PHCL, in mass fraction) displays a high Li+ transfer number (0.73) and exceptional Li+ conductivity at 25 °C (2.5 × 10−4 S/cm). Our work demonstrates a powerful mean to fabricate the efficient electrolyte membrane for SLMBs.
