Abstract

This study evaluates the critical high- and low-temperature rheological properties of a high-viscosity modified asphalt (HVMA) binder by analyzing one neat and three high-viscosity modified binders (B-type, Y-type, and H-type) using temperature sweep tests and multi-stress creep recovery tests (MSCR) through the dynamic shear rheometer (DSR), and low-temperature creep stiffness properties by the bending beam rheometer (BBR). Technical indexes such as the softening point temperature, dynamic viscosity, rutting factor, unrecoverable creep compliance, and the creep recovery rate are measured and calculated for high-temperature properties, while the m/S value, dissipation energy ratio, relaxation time, elongation, creep stiffness, and creep speed are used as technical indexes for low-temperature properties. The results show that the incorporation of high-viscosity modifiers reduces the unrecoverable creep compliance and increases the creep recovery rate of the asphalt binder. Non-recoverable creep compliance is found to be a reliable indicator for high-temperature performance, while at low temperatures, the relaxation time decreases, the dissipation energy increases, and the stress relaxation ability improves. The dissipation energy ratio and m/S value are suggested to evaluate the low-temperature performance of HVMA binders using the Burgers model based on the BBR bending creep stiffness test. Therefore, this study recommends using the unrecoverable creep compliance via MSCR to evaluate high-temperature properties and dissipation energy ratio and m/S value for low-temperature properties in the evaluation of HVMA binders.

Abstract

The development of bulk materials with ferroelectric/antiferroelectric (FE/AFE) phase transitions is of importance for meeting the needs of advanced electronic equipment. Here, we report a (1 − x)Pb(Lu0.5Nb0.5)O3-xPbTiO3 (abbreviated as PLNT100x) system, which shows a particular FE/AFE-like phase transition. A partial phase diagram with low PT content was delimited on the basis of the X-ray diffraction, differential scanning calorimeter, second harmonic generation, ferroelectric hysteresis loops and first-order reversal curve (FORC) methods. The intermediate phase showed AFE hysteresis loops may stem from the weakly polar to the polar phase during electrical poling and the lowering long-range ordering degree. It is a guideline to modulate the electric properties of PLNT AFE system such as Curie temperature, energy storage density and pyroelectric properties, by means of the control of composition.

Abstract

Lanthanide doping is widely employed to tune structural change temperature and electrical properties in ABO3-type perovskite ferroelectric materials. However, the reason that A-site lanthanide doping leads to the decrease of the Curie temperature is still not clear. Based on the reported Curie temperature of lanthanides (Ln) doped in two classic ferroelectrics PbTiO3 and BaTiO3 with A2+B4+O3-type perovskite structure, we discussed the relationship between the decrease rate of Curie temperature (ΔTC) and the bond strength variance of A-site cation (σ). For Nd ion doped Pb(Mg1/3Nb2/3)O3-PbTiO3 (Nd-PMNT) ferroelectric crystal as an example, the internal factors of the dramatic decline of the Curie temperature induced by A-site Nd doping were investigated under a systematic study. The strong covalent bonds of Ln-O play an important role in A-site Ln composition-induced structural change from ferroelectric to paraelectric phase, and it is responsible for the significant decrease in the Curie temperature. It is proposed that the cells become cubic around the Ln ions due to the strong covalent energy of Ln-O bonding in A-site Ln doped A2+B4+O3 perovskite ferroelectrics.

Abstract

The application of circulating tumor DNA(ctDNA) represents a non-invasive method for tumor detection. Its prognostic significance in patients with colorectal cancer is controversial. We performed a systematic review of data from published studies to assess the prognostic values of ctDNA in patients with colorectal cancer. We searched Medline, Embase, Web of Science, the Cochrane Library, and Scopus databases to identify eligible studies reporting disease-free survival (DFS) and overall survival (OS) stratified by ctDNA prior to December 6, 2016. We evaluated the quality and design of these studies. A total of 22 studies were eligible for systematic review. Among them, 11 studies investigated the prognostic value of ctDNA on disease-free survival (DFS). Seven of 11 studies showed that ctDNA was an independent variable to estimate the probability of DFS by multivariate analyses. Thirteen studies assessed the relationship between ctDNA and overall survival (OS). Eight of 13 studies showed that ctDNA was an independent predictor of worse OS through the use of multivariate analyses. This analysis provides evidence that ctDNA may be a prognostic biomarker, negatively correlated with the survival of patients with colorectal cancer.

Abstract

The phase diagram of the Pb(Lu0.5Nb0.5)O3-PbTiO3 (PLN-PT) binary system was previously reported based on XRD and dielectric measurements results. Unusually, the Curie temperature of PLN-PT with low PT obtained from the phase diagram is much lower than that of PLN and PT end members, which is different from others, such as PZT. Therefore, the complex structure of PLN-PT with low PT is desired to be studied. In this work, PLN-PT single crystals with low PT were grown for the study of their super-lattice structure and phase evolution. The super-lattice reflections were identified by X-ray diffraction. Domains and their evolution by heating from room temperature to 150 °C were observed under a polarized light microscope. The phase transition from the ferroelectric phase to the paraelectric phase was determined by dielectric spectra and polarized light microscopy. A precursor/intermediate phase exhibiting pinched hysteresis loops was displayed above the Curie temperature, which originates from some polar region embedded in the non-polar matrix. The coexistence of the ferroelectric and antiferroelectric domains leads to peculiarities of the phase transitions, such as a lower Curie temperature compared with PLN and PT. The studies of the phase evolution of PLN-PT with low PT single crystal is a supplementary amendment of the PLN-PT phase diagram as previously reported.

Abstract

Large-size Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT) based ferroelectric single crystals have been grown successfully by the vertical Bridgman method for application in the field of high-end piezoelectric devices. The piezoelectric and dielectric performance uniformity of PMN-PT based ferroelectric crystals is a critical application requirement. Recently, alternating current poling (ACP) has attracted much attention due to its low cost and high efficiency in improving the piezoelectric properties of PMN-PT based crystals. Here, we report the comparison of the performance fluctuation of direct current poling (DCP) and ACP Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3 (PIN-PMN-PT) ferroelectric single crystals grown in the [110] direction using the vertical Bridgman method. The fluctuation of piezoelectric coefficient d33, dielectric constant ɛT33/ɛ0, and dielectric loss tanδ was presented. We found that the average d33 and ɛT33/ɛ0 of ACP samples are 1290 and 1500 pC/N and 3890 and 4290 for two different wafers, which were 18% and 23%, 21% and 26% higher than DCP samples. The tanδ of ACP samples was much lower than that of DCP samples. The DCP and ACP samples exhibited the close data of the fluctuation ratios of d33 and ɛT33/ɛ0. The fluctuation ratios of d33 and ɛT33/ɛ0 for DCP and ACP samples are all less than 10%. This work offers a reference for practical ACP technique applications.

Abstract

Summary Ferroelectrics with switchable spontaneous polarization have taken a dominant position as the nonlinear optical candidates, of which birefringence is an essential merit to optical devices. Despite the increasing advance of hybrid perovskite ferroelectrics, it remains a great challenge to control and tune their birefringence, thus hindering their practical optical applications. Here, we present a 2D trilayered hybrid perovskite-type ferroelectric obtained by 3D-to-2D dimensional tailoring, [(CH3)2CH(CH2)2NH3]2(CH3NH3)2Pb3Cl10, showing biaxial polarizations of ∼5 μC/cm2 and a relatively wide optical band gap. The intrinsic 2D architecture results in highly anisotropic principal refractive indices, namely, the optical birefringence. Interestingly, its birefringence can be reversibly switched through ferroelectric-to-paraelectric symmetry breaking. The birefringence tuning is further established by virtue of pretransitional modulation of ferroelectricity, exhibiting unusual polarization-dependent behaviors. In our judgment, this study on the polarization-dependent birefringence of hybrid perovskite ferroelectrics will provide a new pathway toward modulating nonlinear optical properties for smart devices.

Abstract

Large pyroelectric and energy harvesting properties have been attracting increasing attentions due to the practical applications in infrared detectors and energy harvesting technologies. Ferroelectric-antiferroelectric (FE-AFE) phase transitions are usually accompanied by a sharp drop in polarization, which will lead to excellent pyroelectric properties and energy harvesting density. Therefore, FE-AFE phase boundary design is an effective strategy to develop new pyroelectric materials. In this paper, Pb(Lu1/2Nb1/2)O3-PbTiO3 (PLN-PT) single crystals with FE-AFE phase transitions were obtained by molten salt growth method. The temperature-induced FE-AFE phase transition was verified by temperature-dependent macrodomain structure, DSC curves and dielectric properties. Obviously, PLN-PT crystals display excellent peak pyroelectric coefficient (∼6.8 μC/(cm2·K)) with a maximum depolarization temperature of 118 °C. Meanwhile, the pyroelectric energy harvesting density is as high as 2.62 J/cm3, which is much higher than other pyroelectric materials. The results reveal that the PLN-PT crystal is a promising candidate for infrared detectors and energy harvesting devices.

Abstract

Observation of high energy and very high emission from Gamma Ray Bursts (GRBs) is crucial to study the gigantic explosion and the underline processes. With a large field-of-view and almost full duty cycle, the Water Cherenkov Detector Array (WCDA), a sub-array of the Large High Altitude Air Shower Observatory (LHAASO), is appropriate to monitor the very high energy emission from unpredictable transients such as GRBs. Nevertheless, the main issue for an extensive air shower array is the high energy threshold which limits the horizon of the detector. To address this issue a new trigger method is developed in this article to lower the energy threshold of WCDA for GRB observation. The proposed method significantly improves the detection efficiency of WCDA for gamma-rays around the GRB direction at 10-300 GeV. The sensitivity of the WCDA for GRB detection with the new trigger method is estimated. The achieved sensitivity of the quarter WCDA array above 10 GeV is comparable with that of Fermi-LAT. The data analysis process and corresponding fluence upper limit for GRB 190719C is presented as an example.

Abstract

Strong second-harmonic generation (SHG) and a wide band gap are two crucial but often conflicting parameters that must be optimized for practical nonlinear optical (NLO) materials. We report herein the first d0-transition-metal (TM) tellurite with half of the d0-TM-octahedra partially fluorinated, namely, quinary RbTeMo2O8F, which exhibits giant SHG responses (27 times that of KH2PO4 (KDP) and 2.2 times that of KTiOPO4 (KTP) with 1064 and 2100 nm laser radiation, respectively), the largest SHG values among all reported metal tellurites. RbTeMo2O8F also possesses a large band gap (3.63 eV), a wide optical transparency window (0.34-5.40 μm), and a significant birefringence (Δn = 0.263 at 546 nm). Theoretical calculations and crystal structure analysis demonstrate that the outstanding SHG responses can be definitively attributed to the uniform alignment of the polarized [MoO5F]/[MoO6] octahedra and the seesaw-like [TeO4], and the consequent favorable summative polarization of the three distinct SHG-active polyhedra, both induced by partial fluorine substitution on the [MoO6] octahedra.

Abstract

The alternating current poling (ACP) method has been attracting significant attention because of the enhanced piezoelectric and dielectric properties of relaxor-based ferroelectric (FE) crystals with advantages of high-efficiency, time-savings, and ease of operation. The most commonly used poling waveform is the bipolar triangle. Other waveforms have been seldom applied in ACP. However, the waveform plays a significant influence on the fatigue performance of FE materials. Therefore, optimizing the ACP waveform to gain high piezoelectric performance and decrease dielectric loss factors is technologically essential. Here, the effects of ACP waveforms on the piezoelectric and dielectric properties of [001] c -oriented 0.66 PIN-0.34 PT FE crystals were studied. The highest piezoelectric coefficient ${d}_{33}$ (1450 pC/N) and dielectric permittivity $\varepsilon ^{T}_{33}/\varepsilon _{0}$ (3180) were obtained using the sesquipolar triangle waveform while the lowest dielectric loss factors tan $\delta $ (0.99%) was obtained using the unipolar triangle waveform. FE hysteresis loop measurements revealed that the lower coercive field and current density are beneficial for higher piezoelectric performance. Domain analysis showed that ACP samples exhibit a regular domain structure and high density 109° domain walls, which are the critical reasons for enhanced piezoelectric performance. This work provides guidance in designing an ACP waveform to achieve higher performance.

Abstract

High-performance relaxor-PbTiO3 ferroelectric crystals have been widely applied in transduces, sensors and so on. The ferroelectric phase transition temperature restricts their application in automobile, deep oil-well detection and aerospace which requires high thermal stability. Decreasing the effects of ferroelectric phase transition is a promising strategy for improving the thermal stability. Here, the design strategy is structural regulation via rare earth doping tetragonal Pb(In1/2Nb1/2)O3–PbTiO3 (PIN-PT) crystals. The d33, k33 and TC of [001]c-oriented Nd-PIN-PT crystals are 750 pC/N, 87%, 250 °C. Compared with the d33 of tetragonal 0.61PIN-0.39 PT crystals (540 pC/N) and tetragonal 0.35PIN-0.26 Pb(Mg1/3Nb2/3)O3 (PMN)-0.39 PT crystals (530 pC/N), the d33 of Nd-PINT crystals enhance by 39% and 41%. In addition, Nd-PIN-PT crystals have Qm of 110, which is larger than rhombohedral relaxor-PbTiO3 ferroelectric crystals (~50). Although the d33 of Nd-PIN-PT crystals is lower than that of rhombohedral relaxor-PT ferroelectric crystals, the d33 and k33 are stable up to 250 °C, which is higher than tetragonal PIN-PMN-PT crystals (210 °C). The high thermal stability of piezoelectric properties is related to the high thermal stability of domain after poling. This work provides a design strategy for high thermal stability ferroelectric crystals.

Abstract

Employing π-conjugated anionic groups in molecular construction has been proven to be an effective strategy to find superior ultraviolet (UV) nonlinear optical (NLO) crystals over the decades. Herein, unlike the traditional π-conjugated anionic groups, we identify that a π-conjugated cationic group, viz., [C(NH2)3]+, is also an excellent UV NLO-active functional group in theory. Furthermore, we identify a [C(NH2)3]+-containing compound, C(NH2)3ClO4, as a promising UV NLO candidate due to its short UV cutoff edge (200 nm), remarkable second-harmonic generation effect (∼3 × KDP), and moderate birefringence of 0.076@1064 nm. Additionally, C(NH2)3ClO4 has excellent ferroelectric properties and reversal of domains, which also enables it to produce ultraviolet coherent light as short as 200 nm by a quasi-phase matching technique with a periodically poling method. Our study may provide not only a promising UV NLO crystal but also a new π-conjugated functional unit, [C(NH2)3]+, which will open a path to finding new classes of high-performance UV NLO crystals.

Abstract

Funding Information: This research was funded by the Scientific and Technological Development Project of Guangxi Communications Investment Group Corporation Ltd., grant number 2021-001. Publisher Copyright: © 2023 by the authors. As the investigation indexes of low-temperature viscoelastic properties of polymer-modified asphalt (PMA) are unclear at present, in this paper, the creep stiffness (S), creep rate (m), low-temperature continuous classification temperature (TC), ΔTC, m/S, relaxation time ((Formula presented.)), and dissipation energy ratio ((Formula presented.)) were taken as a comparison sequence. The maximum flexural tensile strain (εB) of porous asphalt mixture (PAM) in a low-temperature bending test was selected as a reference sequence. Gray relational analysis was used to investigate the PMA’s low-temperature viscoelastic properties based on a bending beam rheometer (BBR). The results show certain contradictions in investigating the low-temperature properties of PMA when only considering the low-temperature deformation capacity or the stress relaxation capacity. The modulus and relaxation capacity should be considered when selecting the investigation indexes of the low-temperature viscoelastic properties of PMA. When rheological method is used to evaluate the low-temperature of polymer modified asphalt, TC and m/S are preferred. When only S or m is contradictory, m should be preferred. ΔTC can determine whether the low-temperature performance of PMA is dominated by S or m. The result can better guide the construction of asphalt pavement in areas with low temperatures. Asphalt can be selected quickly and accurately to avoid the waste of resources.

Abstract

The alternating current poling (ACP) method has been become more and more popular recently because of its advantages of being low cost, time saving and highly efficient. Few ACP studies have focused on relaxor-PT crystals with a high coercive field and high Curie temperature or the effects of ACP on intrinsic and extrinsic contributions. The effects of the electric field, frequency, and number of cycles of ACP on the piezoelectric and dielectric properties of 〈001〉-oriented Pb(In0.5Nb0.5)O3–PbTiO3 ferroelectric crystals were studied. The dielectric permittivity e33T/e0 and piezoelectric coefficient d33 of an ACP sample are 3070 and 1400 pC N−1, respectively, which are 14% and 18% larger than those of a DCP sample. Rayleigh analysis reveals that both intrinsic and extrinsic contributions are enhanced after ACP. The poling electric field, frequency and cycle number can influence the intrinsic and extrinsic contributions. The intrinsic contribution is significantly affected by the poling electric field, and cycle number, but it is not very sensitive to frequency, while the poling electric field, frequency and cycle number are very important for the extrinsic contribution. This work demonstrates that the uniform domain patterns are a critical factor for the enhancement of the piezoelectric properties.

Abstract

This article presents a novel decoupling technique for the circularly polarized multiple-inputmultiple- output (CP-MIMO) system composed of Guoshaped patch antennas. A comparative study has been conducted on antenna performance as a function of packing distance before and after applying the technique. A prototype of two-element Guo-shaped patch MIMO at a small inter-element spacing of 12.5 mm has devised aiming for the 5G new radio n38 (2.57-2.62 GHz) applications. Simulation reinforced with experimental results confirmed the effectiveness of the proposed technique, whereas the two Guo-shaped patch elements packed in such small spacing can be operated independently. Both the envelope correlation coefficient and diversity gain are approaching their ideal values.

Abstract

Electro-optic (EO) materials play a unique and crucial role in modern optical communication and laser science. However, EO materials with large EO coefficient are usually accompanied by serious piezoelectric ringing, which plays an important role in limiting their applications in high frequency and high voltage devices. It is difficult to find a balance between EO coefficient and piezoelectric coefficient. In this paper, we report a new EO crystal, K3Nb3B2O12 (KNBO), acquired from a non-centrosymmetric antiferroelectric (AFE) material. Its EO coefficient is determined to be 3.3 pm V−1, which is comparable with the performance of the commercial EO crystals BBO (2.5 pm V−1) and LGS (2.3 pm V−1). The KNBO crystal exhibits high transmittance (nearly 80%) and a wide optical transparency range (from 327 nm to 4.67 μm). Moreover, the KNBO crystal could effectively avoid piezoelectric ringing, due to a negligible piezoelectric coefficient. These balanced properties of the KNBO crystal favor potential EO applications. More importantly, this is the first demonstration of linear EO modulation in an AFE crystal. This work opens the door for the exploration of AFEs as potential EO materials, which simultaneously possess large EO coefficients and overcome piezoelectric ringing.

Abstract

The electric field modulation of photoluminescence in ferroelectric-optical materials as a novel in situ, non-damaging and real-time controllable method has drawn much research focus. The broad bandwidth emission of 33 nm and a tuneable luminescence contrast of 28% were achieved in Nd-doped Pb(Mg1/3Nb2/3)O3-PbTiO3 (Nd:PMNT) tetragonal ferroelectric-optical crystals arising from spontaneous polarization. The study of Nd:PMNT ferroelectric crystals under a cyclic, triangular alternating current voltage wave showed that the change in the photoluminescence intensity subjected to an electric field is mainly related to the 180° domain distribution, rather than the 90° domain. The physical process of electric field tuning luminescence is to control the 180° domain distribution using the external electric field, which thereby effectively tunes the luminescence. This finding restricts the limitation of a specific phase change region, which greatly increases the range of materials used and has guiding significance for research in the electric field modulation of luminescent technology.

Abstract

Owing to the vital role of birefringent materials in various advanced optical systems, it is very important to find and design structures with a large birefringence. Thus, the LaBO3 crystal was investigated. It exhibits a structural characteristic of quasi-two-dimensional [BO3] layers formed by separate [BO3] groups, which leads to a moderate birefringence (0.093@546 nm). Besides, the LaBO3 crystal presents a short ultraviolet absorption cutoff of 237 nm corresponding to the band gap of 5.23 eV (the calculated value of 4.81 eV). Remarkably, the LaBO3 crystal possesses a large transparency window with a transmittance of more than 60% in the region of 300–2000 nm. Therefore, this study points out a promising birefringent crystal and further confirms a favorable structure of the quasi-two-dimensional [BO3] layer to a large birefringence, which could facilitate the design of new ultraviolet and deep-ultraviolet birefringent crystals.

Abstract

Ferroelectric materials are widely applied in capacitors and actuators, which require both good endurance and the stabilization of electrical properties under large AC bipolar electric field cycling, however, the electric fatigue effect severely deteriorates both the endurance and stabilization. Fatigue endurance is greatly modified by point defects. This work reports the enhancement of the endurance and stabilization of Mn-doped Pb(Lu1/2Nb1/2)O3–PbTiO3 ceramics. After doping, the evolutions of remanent polarization, the coercive field and dielectric permittivity exhibited less variation than virgin samples. Defect-related abnormal self-rejuvenation was detected during the fatigue process. Under different re-annealing conditions, it was found that the screening effect of defects along the grain boundaries is responsible for the enhancement of the fatigue endurance and the stabilized fatigue behavior. This research reveals the mechanism of the abnormal self-rejuvenation effect in acceptor-doped ceramics and provides a potential method by which to control fatigue behavior via defect engineering.

Abstract

Nonlinear optical crystals play important roles in modern laser science and technology. However, the design and growth of new nonlinear optical (NLO) materials is still a challenging issue for researchers. Due to the excellent performance of Mg3B7O13Cl crystal, we paid attention to the optimization of its structure, in order to find new NLO materials with favorable properties. Here, Zn3B7O13Cl crystals were obtained by a high-temperature solution method. Its structure was determined to be the trigonal symmetry with a polar space group of R3c, which is more highly symmetric than that of Mg3B7O13Cl (Pca21). The experimental and theoretical investigations demonstrated that the title compound exhibits a short absorption cutoff (band gap ∼6.53 eV), moderate SHG responses (2.2 times that of KDP at 1064 nm), and the improved birefringence, which results from the large distortion and anisotropy of borate groups and zinc polyhedrons. Therefore, the structural modification of Mg3B7O13Cl by zinc cations achieves a balance between the deep-ultraviolet transparency, the nonlinear optical effect, and the moderate birefringence, which is very significant for the design of practical NLO materials.

Abstract

Freight forwarding companies commonly encounter difficulties in handling uncertainties, especially demand uncertainty under the circumstances of no sufficient historical data or accurate forecasting approach. A two-stage robust optimization method is proposed for service network design under demand uncertainty. We employ probability-free uncertainty sets to illuminate the potential scenarios and develop a column-and-constraint generation approach as the solution method to solve the introduced robust models exactly. As indicated by the numerical results, the algorithm we proposed herein performs better than the Benders decomposition approach in terms of computing speed and quality of the solution. Comparative results demonstrate the robustness of the proposed models. We also analyze the structural properties of robust solutions, which provide operational flexibility against uncertainty.

Abstract

The ferroelectric to antiferroelectric (FE-AFE) phase boundary design based on orthorhombic AFE phase and tetragonal FE phase is an effective method to develop high-performance pyroelectric materials due to the complete release of large electrical polarization in FE-AFE phase transition. Herein, we report the phase structure evolution in (1-x)Pb(Lu0.5Nb0.5)O3-xPbTiO3 (abbreviated as PLNT100x) ceramic system based on the relationship of tolerance factors versus electronegativity differences. The composition/temperature effects on FE-AFE phase transition behavior, pyroelectricity, depolarization temperature (Td) and energy harvesting performance were investigated systematically. Obviously, PLNT system displays superior pyroelectric characteristics as well as high Td. The maximum pyroelectric peak was 4.50 μC·cm−2·K − 1 over a wide temperature range from 28 °C to 167 °C. In addition, the obtained maximum pyroelectric energy harvesting density was 1.66 J/cm3 which was much higher than the currently reported values, indicating a potential candidate for pyroelectric energy conversion applications. Based on the modified Ginzburg−Landau−Devonshire (GLD) phenomenology, the composition/temperature driven phase transitions were discussed, and the temperature−electric field (T − E) phase diagram was accordance with actual phase diagram based on the experimental data.

Abstract

Compared with pure Pb-based perovskite ferroelectric materials, BiMeO3–PbTiO3 (Me = Sc3+, In3+, and Yb3+) systems have remarkable advantages in their Curie temperatures. As a member of this group, the BiScO3–PbTiO3 (BS–PT) solid solution has drawn considerable attention from scientists for its high Curie temperature and excellent piezoelectric coefficient. However, BS–PT ceramics still have some shortcomings, such as high dielectric loss and low mechanical quality factor, which make them unsuitable for high-temperature applications. Herein, we report the effect of the addition of complex ions on the electrical properties of BS–PT ceramics. Sb2O3-doped 0.36BiScO3–0.64PbTi0.97Fe0.03O3 + 1 mol% MnO2 (BS–PTFMn + x% Sb2O3) ceramics were fabricated and their electrical properties were studied. BS–PTFMn + 0.75% Sb2O3 had an optimal piezoelectric coefficient, exhibiting which indicates that Sb2O3 doping can improve the piezoelectric properties of the BS–PT ceramics, exhibiting a “soft” effect of Sb2O3 doping. In addition, the thermal depolarization temperature (Td) of BS–PTFMn + 0.75% Sb2O3 ceramics remained above 300 °C, such as 325 °C for BS–PTFMn + 0.75% Sb2O3. It was concluded that the piezoelectric properties of BS–PT ceramics were enhanced by the addition of Sb2O3.

Abstract

Antiferroelectric (AFE) materials have attracted tremendous attention and research interest as a family of important multifunctional electroactive materials, due to the special double polarization versus electric field (P–E) hysteresis loops. However, AFE compounds are quite rare and structure types of AFE materials are considerably scarce. It is tremendously difficult to find new AFE materials with a novel structure type. In this work, we discovered a new lead-free AFE crystal, K3Nb3B2O12 (KNBO), which is the first borate AFE material that provides a novel structure type for the AFE materials. Another extraordinary feature of KNBO crystal is that it crystallizes in the polar space group P21ma, exhibiting a moderate second harmonic generation response (0.24 × KH2PO4), which is unusual for AFE materials. Local dipole moment calculation was performed to analyse the structure–property relationships, which reveals that anti-polar and polar structures coexist in the KNBO crystal, moreover the anti-polar direction is perpendicular to the polar direction. This special structural characteristic leads to the coexistence of the AFE effect and SHG response. The discovery and characterization of the KNBO AFE crystal not only provide a new insight into the structure–property relationships of AFE materials, but also indicate a new way for searching and designing AFE functional materials.

Abstract

Using data samples with a total integrated luminosity of $20.1~\rm fb^{-1}$ collected by the BESIII detector operating at the BEPCII collider, the cross section of the process $e^+e^- \rightarrow \pi^+\pi^-\psi(3686)$ is measured at center-of-mass energies between 4.0076 and 4.6984 GeV. The measured cross section is consistent with previous results, but with much improved precision. A fit to the measured energy-dependent cross section, which includes three Breit-Wigner functions and a non-resonant contribution, confirms the existence of the charmonium-like states $Y(4220)$, $Y(4390)$, and $Y(4660)$. This is the first observation of the $Y(4660)$ at the BESIII experiment.
