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 ：
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.

Abstract ：
Optical information encryption is closely related to information security, and smart hydrogels with tunable optical properties under external stimuli have received much attention as optical storage materials. However, it is still challenging to achieve complex information camouflage and large-capacity information storage in hydrogel systems. Herein, a hybrid encoding strategy afforded by an aggregation-induced emission (AIE) fluorescent hydrogel with multi-stimuli responsiveness is pioneered as a feasible alternative for multiple camouflage strategies. More specifically, the photoluminescence intensity of a system can be independently or mutually tuned by specific stimuli, including solvent (DMSO/H2O), pH (NaOH/HCl), and metal ions (Fe3+/EDTA(2-)), leading to the precise protection or decoding of encrypted information. That is, only the correct stimulus sequence can unlock the stored real information, thus enabling the system with the functionality of multilayer encryption and on-demand decryption of information. We envisage that the present strategy of multiple information carrying and showcasing in AIE hydrogels through stimulation sequence regulation exhibits great potential for secure information writing and anticounterfeit encryption.

Abstract ：
Electrocaloric cooling based on ferroelectrics is an eco-friendly technology. BaTiO3 (BT)-based ferroelectric ceramics possess a high electrocaloric effect, which is significantly affected by grain size. Herein, fine and large grains' contributions to electrocaloric and related properties in BT-based ceramics are revealed via tuning sintered dwelling time (t(s)) in discontinuous grain growth (DGG) process with fine and large grains coexistence. With increasing t(s), grain size change can be divided into two stages. The main change is the large-grain size (>100-200 mu m) and number in the beginning DGG stage, and the properties' evolutions are mainly contributed by large grain change. The bigger grain size of large and fine grains contributes to the higher electrocaloric property, sharper phase transition, ferroelectric polarization (change rate), and coercive field. In the subsequent stage, fine grains gradually grow up (similar to 4.0-5.0 mu m) while large-grain size decreases slightly. Here the properties' evolutions are influenced by the competitive contributions between fine and large grains. Large grain contribution is mainly attributed to the domain size effect, and fine grain contribution should embrace the domain size effect and grain-boundary pinning effect. This work contributes to a broad understanding of fine/large grain contributions in the promising BT-based electrocaloric ceramics.

Abstract ：
Photoferroelectrics that involve strong light-matter coupling are regarded as promising candidates for realizing bulk photovoltaic and photoelectric effects via light absorption. Nonetheless, understanding the photoresponse mechanism or modulation of performance from a microscopic point of view is scarcely explored through quantification of macroscopic properties. Herein, we design a model material, Gd3+-doped (K0.5Na0.5)NbO3 ferroelectric-transparent ceramics, and present an advantageous strategy to enhance the optoelectronic coupling through joint modulations of lattice distortion and oxygen vacancies, along with inner defects and ferroelectric domains. Significantly, their microcosmic manipulation can be intuitively and facilely evaluated by the optical transparency of each ceramic. An approximately 10(4) fold increase in conductivity under ultraviolet irradiation was produced. Under the cocoupling between external physical fields, the synergy of photoelectric stimulation increased the photoconductivity of the ceramics by 13.89 times. Additionally, a significant increase (4.5-fold) in the current output from the photovoltaic effect was achieved via ferroelectric domains of moderate size, whose size could be easily assessed by optical transmittance. In situ microscopic observations confirmed that the configuration of oxygen vacancy-dependent ferroelectric domains contributes to the enhanced optoelectronic response. This research provides a distinct way to develop inexpensive optocoupler devices and meet the requirements for multifunctional integration in single photoferroelectrics.
