Piezoelectric materials are widely used in the direction of sensors. PZT-based ceramics are very suitable for precision sensors. However, due to the low Curie temperature, the application temperature range of the material is relatively narrow. Here we show a high-performance material 0.6PZT–0.4PNN. In this case, a morphotropic phase boundary (MPB) region was artificially designed in the 0.6Pb(Zr x Ti 1 −x )O 3 –0.4Pb(Ni 1/3 Nb 2/3 )O 3 ( x = 0.35–0.41) ceramics to develop high-performance piezoelectric compositions which could cofire with low-cost Ag/Pd inner electrode by 0.2wt% Li 2 CO 3 addition. The ceramic composition at x = 0.39 near MPB possess exceptional properties with high piezoelectric coefficient d 33 ∼ 611 pC/N, planar electromechanical coupling coefficient k p ∼ 53.5%, low mechanical quality factor Q m ∼ 64.5 piezoelectric strain of 0.17%, and suitable Curie temperature T c ∼ 191 °C, respectively. The fact that d 33 was detected close to T c , and no noticeable change below 6.6% in cycling stability was observed at 20 kV/cm means a robust temperature-independence and fatigue reliability of the piezoelectric ceramics. Thus, this research provides a novel high-piezoelectricity configuration with elemental regulation, comparable to the commercial PZTs.

High efficiency ( η ) is urgently desired for electronic energy storage devices. In this work, an extremely high energy storage efficiency (~ 99.5%) and energy storage density of 2.83 J/cm 3 are achieved in lead-free relaxor ferroelectric (1– x )(0.9BaTiO 3 –0.1BiMg 0.5 Ti 0.5 O 3 )- x Bi(Mg 0.5 Sn 0.5 )O 3 [(1– x ) (0.9BT–0.1BMT)– x BMS] ceramic ( x = 0.09). Excellent temperature stability with a variation of η less than 1.5% is also obtained in a wide temperature range from 30 to 150 °C. Temperature dependence of the dielectric permittivity of (1– x )(0.9BT–0.1BMT)- x BMS exhibits a typical dipolar-glass-like relaxor ferroelectric behavior. As a result, the ultra-high efficiency of the ceramic is attributed to the weak-coupling polar nanoregions (PNRs) which are analyzed using the Vogel-Fulcher formula and phenomenological statistical model. These results not only help to understand the origin of high efficiency in the (1– x )(0.9BT–0.1BMT)- x BMS system but also provide an effective approach to improve the comprehensive properties of other lead-free ceramic systems used in next-generation power capacitors.

Modern electronic devices are highly in demand for high-performance piezoelectric materials. Herein, Pb(Ni, Nb)O3–Pb(Lu, Nb)O3–PbTiO3 piezoelectric ceramics are investigated, among which the 0.52PNN–0.16PLN–0.32PT ceramic shows the best performance (d33 = 850 pC N−1, d33* = 1139 pm V−1). Excellent piezoelectricity can be explained by multiphase coexistence, as well as an enhanced local heterogeneous structure. Polar nanoregions that promote polarization rotation are an important cause of high piezoelectricity according to characterization using SEM and PFM. TEM also confirmed a heterogeneous domain configuration with two coexisting phases. In addition, a large signal piezoelectricity of 1000 pm V−1 is maintained in the temperature range of 20–90 °C. This work presents an excellent example of achieving both high piezoelectric properties and a good temperature range in relaxor ferroelectric ceramics.

The multilayer electrocaloric ceramics (MLEC) are promising candidates for environmentally friendly refrigeration, since it possesses large electrocaloric effect (ECE) at a relatively low applied voltage. In this work, factors that may influence the ECE of MLEC are investigated. Experimental results demonstrate that the ECE of MLEC is strongly related to its effective volume fraction, and the effective volume fraction of the MLEC can be tailored by changing the thickness of the MLEC protective layer. Measurements show up to a 33.3% improvement of adiabatic temperature change when the thickness of MLEC protective layers is decreased by 70.0%. Meanwhile, the relaxation and the temperature range of the MLEC is increased with the increase of frequency. The enhanced ECE response is obtained over a broad temperature range from 0 °C to 50 °C in MLEC. It is found that the ECE response of MLEC could be enhanced by thinning the protective layer, and this enhancement is induced by the increasing of the effective volume fraction which is caused by the protective layer thinning. As a result, this work provides an effective and feasible way to develop high-performance MLEC components.

In this work, the combined ultraviolet ozone process (UV/O 3 ) was applied for organic contaminant (Reactive Blue K-GL, RB) degradation in high salinity . The degradation rates of RB in both O 3 and UV/O 3 systems were enhanced by NaCl (the k increased from 0.080 to 0.116 to 0.132 and 0.267 min −1 respectively), while mineralization rate varied at different salt conditions. In addition, UV irradiation promoted the degradation efficiency of RB with the presence of salt. Singlet oxygen ( 1 O 2 ) was the primary active species in the UV/O 3 system. The quenching experiments and signal intensity of 1 O 2 corresponded well to the mineralization of RB. Under conditions of high salinity and high pH, O 3 has high mass transfer coefficient (k La , 3.303 min −1 ) and self-decomposition (k d , 0.600 min −1 ), which further promoted the formation of 1 O 2 for mineralization of RB. Furthermore, UV/O 3 system was efficient in real textile wastewater treatment (COD Cr removal rate 91.7% and decolorization rate 98.7%).

(1-x)(0.9Ba 1.003 Ti 0.97 Ca 0.03 O 3 –0.1(Bi 0.51 Na 0.47 ) 0.94 Ba 0.06 TiO 3 )-xNa(Nb 0.85 Ta 0.15 )O 3 ( x = 0.03–0.15) ceramics were designed and fabricated through a bidirectional optimization strategy using traditional solid reaction method. The results revealed that the introduction of Na(Nb 0.85 Ta 0.15 )O 3 increased the vacancy concentration at the A site , conducing to improved polarization and reduced grain size. The substitution at the B site disrupted the long-range ordered ferroelectric domains and generated polar nanodomains, leading to enhanced relaxation behavior. The optimum energy storage density of 3.57 J/cm 3 and efficiency of 87.5% were simultaneously achieved under the electric field of 220 kV/cm in the sample with x = 0.09. Moreover, it also exhibits extremely high-power density (∼57 MW/cm 3 ), ultrafast discharge time (∼103 ns), high discharge density (1.35 J/cm 3 ), along with excellent temperature (30‒120 °C) and frequency stability (1‒100 Hz) under the equivalent electric field of 120 kV/cm. This novel design strategy provides theoretical guidance for the development of advanced electrical energy storage devices.

Temperature stability of the piezoelectric ceramics is critical to its performance in high-power devices. In this research, 5 mol% BiScO 3 (BS) is introduced into 0.05Pb(Mn 1/3 Sb 2/3 )O 3 –Pb(Zr 1− x Ti x )O 3 system. The morphotropic phase boundary (MPB) has been re-located by shifting Zr/Ti ratio systematically for the piezoceramic. Optimal piezoelectric properties with piezoelectric coefficient d 33 of 341 pC/N, electromechanical coupling factor ( k p ) of 0.51, and mechanical quality factor Q m value of 859 are obtained in MPB compositions of 0.05BiScO 3 –0.05Pb(Mn 1/3 Sb 2/3 )O 3 –0.9Pb(Zr 45.5 Ti 54.5 )O 3 ceramic at room temperature. Furthermore, the addition of BiScO 3 effects profoundly on the temperature dependence of the piezoelectric and ferroelectric properties. Comparing to common Pb(Zr, Ti)O 3 -based piezoceramic, the BS-doped ceramic presents elevating ferroelectric polarization with temperature up to 200 °C, as well as stabilized d 33 , k p , and Q m values from room temperature to 120 °C.

0.6Bi(Mg0.5Ti0.5)O3–0.4Ba0.8Ca0.2(Ti0.875Zr0.125)O3 (0.6BMT–0.4BCZT) ceramics exhibit an ultrahigh dielectric thermal stability. In this work, the relationship between the local structure and the physical properties of this system is revealed using in situ XRD, in situ Raman, TEM and dielectric responses. It is found that the formation and freezing of both polar nanoregions (PNRs) and nanomosaic structures (NMSs) that comprise ferroelectrically active Ba/Ti rich and weakly polar Bi (and Mg) rich phases are responsible for the high dielectric thermal stability. Three dielectric anomalies, i.e. low-temperature re-entrant dipole-glass-like relaxor behavior, mid-temperature diffuse phase transition (DPT), and high-temperature local phase transitions can be described using the phenomenological statistical model. Furthermore, the relaxor behavior follows the Vogel–Fulcher law and the new glass model. The dipole-glass-like relaxor nature of 0.6BMT–0.4BCZT was characterized by P–E loops. The beta value obtained from the isothermal electrical modulus shows three critical temperatures corresponding to the formations of PNRs, NMS and local phase transition of calcium-containing perovskites.

Piezoelectric materials have wide commercial applications involving our everyday lives. The common categorized “soft” and “hard” piezoelectric materials have distinct even contradictory performance parameters typically exemplified by piezoelectric coefficient d 33 and mechanical quality factor Q m . However, for some special devices operated in resonant mode, simultaneously high or at least balanced performance parameters are needed. Here, we show the transition from “soft” to “hard” performance in 2 mol% Sm doped (0.36- x )Pb(Ni 1/3 Nb 2/3 )O 3 - x Pb(Mn 1/3 Nb 2/3 )O 3 -0.28PbZrO 3 -0.36PbTiO 3 quaternary solid solution piezoceramics, for which the d 33 and planar electromechanical coupling factor k p decrease, while Q m and Curie temperature T c increase monotonously with increasing x value. As the results, balanced performance with moderate d 33 = 446 pC/N, k p = 0.49, Q m = 425, and T c = 170 °C are achieved around x = 0.03. This work not only shows the feasibility for combining “soft” and “hard” performance by forming appropriate solid solutions, but also provides a suitable material basis for further simultaneously optimizing piezoelectric parameters.

Relaxor-based ternary Pb( In 1 / 2 Nb 1 / 2 )O 3 –Pb( Mg 1 / 3 Nb 2 / 3 )O 3 –PbTiO 3 (PIN–PMN–PT) single crystals and ceramics are promising candidates for high-performance electromechanical conversion devices. It is known that the domain structure and dielectric diffusion–relaxation characteristics are crucial to the excellent performances of relaxor ferroelectrics. In this work, we prepared the PIN–PMN–PT ceramics with various PIN/PMN proportions and systematically investigated their domain structure and dielectric diffusion–relaxation properties. The effect of PIN/PMN proportion on the domain size and dielectric diffusion–relaxation characteristics was also studied. The investigations showed that PIN–PMN–PT ceramics presented multi-type domain patterns comprising irregular island domains and regular lamellar domains. Moreover, the dependent relations of PIN/PMN proportions on the dielectric diffusion and domain size indicated that the PIN composition has a stronger lattice distortion than PMN composition; increasing the PIN proportion can enhance the dielectric diffusion and decrease the domain size. Our results could deepen the understanding of structure–property relationships of multicomponent relaxor ferroelectrics and guide the design and exploration of new high-performance ferroelectric materials.

In recent years, compared with traditional refrigeration technology, the electrocaloric refrigeration technology has been applied in variety of green cooling devices due to its high efficiency and environmentally friendly. Recent findings reveal that the ceramic system with additives (such as, LiBiO 2 , PbO) can create large ECE under low electric field. In this work, the ternary glass BaO–CaO–SiO 2 (BCS) was used as a sintering aid to enhance the electrocaloric (EC) response of 0.2Ba(Ti 0.9 Sn 0.1 )O 3 -0.8Ba(Zr 0.18 Ti 0.82 )O 3 (BZSnT20) bulk ceramics. The EC properties of BZSnT20 could be also improved via controlling sintering temperature and the content of BCS sintering aid. It was found that BZSnT20 with 0.5 wt% BCS show the maximum EC response of 3.2 K under 7 MV/m with sintering temperature of 1262 °C. These results demonstrated that the ECE of BZSnT20 can be boosted by using appropriate additives, which provides an effective route to realize large ECE under low electric fields.

The frequent detection of chloramphenicol (CAP) in wastewater and surface water gives rise to concerns on its fatal myelosuppression and aplastic anemia. Recently, the combination of ozone and peroxymonosulfate (O 3 /PMS) has received wide attention in removing pollutants due to the multiple oxidants (i.e., O 3 , hydroxyl radicals ( OH) and sulfate radicals (SO 4 − )) existed therein. This study showed that O 3 /PMS could effectively degrade CAP under various conditions. The second-order rate constant of CAP with O 3 , OH and SO 4 − was 0.291 ± 0.005 , 2.27 ( ± 0.03 ) × 10 9 and 1.02 ± 0.02 × 10 8 M - 1 s - 1 , respectively. The degradation efficiency of CAP was significantly enhanced as PMS concentration or pH increased. Bicarbonate (HCO 3 − ) at concentration of 5 mM slightly inhibited CAP degradation at pH 7. Chloride (Cl − ) at concentration of 0.5 mM enhanced CAP removal at pH 7, while this enhancement gradually weakened as Cl − concentration further increased. The degradation efficiency of CAP first increased with increasing natural organic matter (NOM) concentrations (0.1–0.3 mg/L), while it was completely suppressed at higher NOM concentrations (0.5 mg/L). Four degradation products in total of CAP were identified in O 3 -based processes (i.e., O 3 , O 3 /TBA, O 3 /H 2 O 2 , O 3 /PMS and O 3 /PMS/ tert -butyl alcohol (TBA) systems. Besides, these transformation products by OH, SO 4 − and/or O 3 were also distinguished. Finally, the impact of O 3 /PMS pre-oxidation on the formation of dichloroacetamide (DCAcAm) from CAP during post-chlorination process was investigated. Compared with the traditional O 3 and O 3 /H 2 O 2 processes, O 3 /PMS pre-oxidation generally led to the least generation of DCAcAm under similar conditions, where SO 4 − rather than OH was conducive to relieve the formation of DCAcAm. Moreover, the presence of NOM obviously alleviated the formation of DCAcAm by O 3 /PMS pre-oxidation.
