Abstract ：
Energy storage high-entropy ceramics are famous for their ultrahigh power density and ultrafast discharge rate. However, achieving a synchronous combination of high energy density and efficiency along with intelligent temperature-monitorable function remains a significant challenge. Here, based on high-entropy strategy and phase field simulation, the polarization response of domains in Bi0.5Na0.5TiO3-based ceramics is optimized by constructing a concomitant nanostructure of defect dipole polarization and a polymorphic relaxor phase. The optimal ceramic possesses a high recyclable energy storage density (11.23 J cm-3) and a high energy storage efficiency (90.87%) at 670 kV cm-1. Furthermore, real-time temperature sensing is explored based on abnormal fluorescent negative thermal expansion, highlighting the application of intelligent cardiac defibrillation pulse capacitors. This study develops an effective strategy for enhancing the overall energy storage performance of ferroelectric ceramics to overcome the problems of insufficient energy supply and thermal runaway in traditional counterparts.

Abstract ：
The intricate composition of real-world aquatic systems significantly constrains the improved overall performance of powder catalysts, meanwhile their recyclability is inferior to the bulk counterparts (e.g. aerogels). Herein, by loading BiOBr onto g-C3N4 nanosheets and combining them with agarose, an S-scheme heterojunction aerogel (abbreviated as BCA) was synthesized, whose structure was confirmed by the density functional theory calculation. Importantly, the BCA could activate peroxymonosulfate (PMS) under simulated sunlight for degrading multi-pollutant. And the BCA/PMS/Light system efficiently degraded various organic contaminants in aqueous environments, achieving a high degradation rate constant of 0.1503 min- 1 for rhodamine B (RhB), significantly surpassing the performance of CA/PMS/Light (0.0378 min- 1) and BCA/PMS (0.0763 min- 1) systems. Free radical quenching experiment and electron paramagnetic resonance analysis reveal that 1O2, center dot O2-, center dot OH and SO4 center dot- in the BCA/PMS/Light system were pivotal in RhB degradation, with a dominant non-radical mechanism. Additionally, Fukui function analysis pinpointed the primary reaction sites within the RhB molecule. The photocatalytic heterojunction aerogel exhibits outstanding stability, environmental sustainability and versatility, which can guide the development of simulated sunlight-driven PMS activation for multi-pollutant degradation, catering for scalable water treatment applications.

Abstract ：
Owing to the difficulty in replication and high security, delayed anti-counterfeiting is an emerging technology for its applicability in encrypting high-precision devices. Materials with photochromic (PC) effects and self-recovery behavior are appropriate candidates for realizing delayed anti-counterfeiting. Herein, Dy3+-doped (K0.5Na0.5) NbO3-based ceramics were designed and prepared via tape-casting method. Down-conversion photoluminescence with white emission, conspicuous PC reaction and dynamic PC self-bleaching process were observed in the ceramics. The concentrations and positions of different defect traps, along with the oxygen vacancies of the ceramics, contributed to PC self-recovery. Taking advantage of the difference in PC self-recovery rates between yellow and blue emissions with time and the difference in color temperatures (C.T.), we propose a method of encrypting, calibrating, and performing C.T. detection on the nodes and paths of a single ceramic for optical signal input. This study will guide the construction of visual-invisible double-encryption anti- counterfeiting systems based on other novel materials.

Abstract ：
Transparent-photochromic materials have garnered significant attention for their applications in optical information storage and anti-counterfeiting, which necessitate excellent transparency and high optical contrast. Herein, x mol% Sr2+ and 1 mol% Ho3+-codoped (K0.5Na0.5)NbO3 (xSr-1Ho-KNN) ceramics were synthesized by a conventional solid-state reaction and pressureless sintering. Notably, the 7Sr-1Ho-KNN ceramic displays exceptional transmittance (60.7% at 780 nm), attributed to its fine grains and highly symmetric crystal structure. The photochromic (PC) contrast based on the change in photoluminescence (PL) intensity of 7Sr-1Ho-KNN under excitation with a 980 nm laser reaches as high as 91.5%. After thermal treatment under appropriate conditions, the transmittance and PL intensity of the ceramic can revert to their respective original values, demonstrating superior optical stability in response to alternating light and thermal stimuli. The combination of high transparency and PC contrast suggests that the xSr-1Ho-KNN ceramics have promising potential for optical information storage and optical anti-counterfeiting applications, which can guide the development of other KNN-based materials or even multifunctional luminescent ferroelectrics.

Abstract ：
The coordination of multiple luminescent centers in a simple and efficient way is a difficult challenge for realizing the tunable multicolor function of fluorescent hydrogels. In this work, we synthesized a fluorescent hydrogel with multicolor conversion via a "one-pot method," which greatly simplifies the tedious steps of preparing fluorescent hydrogels. The luminescence intensity and color of the synthesized DPA-Eu/TPE@PVA hydrogel can be modulated by various stimuli, such as the excitation wavelength, pH, and presence of Fe3+ ions. The entire work centers on the rational introduction of the light-emitting molecule tetrakis(4-hydroxyphenyl)ethylene (TPE-4OH) and the lanthanide ionic complex 2,6-pyridinedicarboxylic acid-Eu (DPA-Eu) into the poly(vinyl alcohol) (PVA) polymer network. Since the luminescence mechanisms of these two molecules differ, with the former emitting light with the aid of the aggregation-induced emission (AIE) effect and the latter emitting light through energy transfer via metal dynamic coordination bonds, individual luminescent molecules can be controlled independently under specific stimuli. The realization of this tunable multicolor fluorescence function has contributed to its application in fields such as sensors, probes, and information encryption.

Abstract ：
The introduction of dynamic covalent bonds into shape memory polymers (SMPs) has offered the possibility of reprocessing, but multifunctional modifications have not been sufficiently investigated. This work reported photoluminescence thermadapt two-way SMPs (2W-SMPs) based on syndiotactic 1,2-polybutadiene (SPB). The ZnS:Cu particles were modified to form beta-hydroxyester dynamic covalent bonds with epoxidized SPB (ESPB), and a dynamic reversible cross-linked network was constructed inside the shape memory polymer. The crystallization-melting characteristics of ESPB and the photoluminescence ability of ZnS:Cu endow the material with two-way shape memory and photoluminescence properties, respectively. Owing to the solid-state plasticity endowed by dynamic covalent bonds, the thermadapt 2W-SMPs can be recycled at high temperatures. In addition, we designed a "gripper" structure via its shape memory ability. The results showed that under variable temperature conditions, this material can successfully grasp objects. Its good photoluminescence effect ensures that the gripper structure can be accurately positioned in a dim environment.

Abstract ：
Lead-free AgNbO3-based antiferroelectric (AFE) ceramics have attracted increasing interest owing to their environmentally friendly nature and excellent potential in energy storage devices. However, the poor breakdown strength (BDS) of AgNbO3 limits its practical application. Herein, the Mn/Sm-codoing strategy and the tape- casting technique were utilized to improve the BDS of AgNbO3-based ceramics to 320 kV cm- 1 , which is almost 1.8 and 1.6 times greater than that of doped AgNbO3 prepared by solid-state reaction and that of pure AgNbO3 prepared by the tape-casting method, respectively. The relatively high BDS is attributed to the improved density, the grain size reduction and the decrease of concentration of oxygen vacancies. As a result, a high energy storage density of 5.18 J cm- 3 with an efficiency of 73.3 % were observed. Our research enriches the fabrication strategy of lead-free AFE ceramics with high BDS and contributes to the applications of AFE-based energy storage devices.

Abstract ：
Achieving high-quality white light and related effective modulation is crucial for the development of solid-state luminescent materials. However, white emission is frequently manipulated through irreversible chemical routes, departing from the actual applications in solid-state lighting devices that require in-situ modulation. In this study, we designed and prepared La3+/Dy3+/Eu3+ tri-doped (K0.5Na0.5)NbO3 transparent-ferroelectric ceramics, which exhibit abundant optical properties and moderate ferroelectricity. For the characteristics of white light, the emission colors could be regulated by adjusting the excitation wavelength. Meanwhile, on the basis of the decrease in photoluminescence intensity due to photochromic (PC) behavior, modulations of white emission and color coordinates were realized. The regulation of optical properties through the physical route (i.e., maneuverable light illumination) is closer to practical application. In addition, the excellent fluorescence temperature sensing properties (a maximum relative sensitivity of 7.81 % K-1 obtained at 233 K) and high PC contrast (75.8 %) of the ceramics provide guidance for the design of other multifunctional optoelectronic materials and devices.

Abstract ：
Eco-friendly BaTiO3 (BTO)-based materials have been intensively studied as efficient piezo-photocatalysts for the degradation of contaminants and water remediation. However, studies on pure BTO are limited due to weak light absorption, insufficient piezoelectric polarization, and poor catalytic performance. Herein, we used different liquid-phase methods to prepare pure BTO particles to enhance the piezo-photocatalytic performance through microstructural manipulation. Compared with the BTO prepared via the hydrothermal method (BTO-HT), the BTO-SG (prepared via the sol-gel method) exhibit smaller particles, larger specific surface area, greater concentration of oxygen vacancies, and larger bandgap energy, resulting in more active sites, stronger piezophotocatalytic ability, improved degradation performance for rhodamine B (97 % within 60 min) with a higher degradation rate constant (5.541 x 10- 2 min- 1) 7.96 times that of the BTO-HT. The catalytic performance of BTO-SG is superior to that of most previously reported BTO-based catalysts. Importantly, synergistic piezophotocatalysis is much better than single photocatalysis (k = 0.757 x 10- 2 min- 1) or piezocatalysis (k = 1.703 x 10- 2 min- 1). In addition, the BTO-SG particles maintained stable degradation performance in environments containing inorganic anions or with various pH values. The degradation mechanism of BTO-SG was proposed in combination with free radical detection and photoelectric tests. This study provides a design thought for exploring other highly efficient BTO-based piezo-photocatalysts for water environment treatment.

Abstract ：
Piezoelectric materials (PEMs) can convert mechanical energy into electrical energy. Substantial works were performed to optimize PEMs and devices for smart sensing, human monitoring, and medical applications, however, their electromechanical behaviors under such scenarios with different applied frequencies remain unclear. Here, the frequency response behaviors of piezoelectric output current are revealed based on lead-free and lead-based PEMs toward advanced applications. The results show a linear relationship between output current and frequency under short-circuit condition, with the slope varying according to loading force (F) and piezoelectric coefficient (d33). However, when a load resistance (RL) is applied, a nonlinear relationship is shown: the current increases with frequency, reaches a critical point, and subsequently levels off. The saturation current is influenced by F, RL, d33, and device capacitance (C), while the critical frequency is related to RL, C, and action distance. This fundamental behavior of PEMs aligns with Maxwell's displacement current deducing and is wellsupported by circuit simulations and physical modeling. The universality of these results is further confirmed through lead-based PEMs. Open-circuit voltage is unaffected by f, while load voltage exhibits the same nonlinear frequency response as load current. Applying these findings by combining machine learning, human posture monitoring and robot motion recognition were achieved. This work gives a deep understanding of intrinsic frequency response behaviors of electromechanical conversion in PEMs and guides the emerging piezoelectric sensing and monitoring applications.
