A call for further study and use of transformational leadership in pharmacy education and practice: Hope and reinvigoration

This paper calls for further study of transformational leadership and its further use in educating PharmD students as well as inclusion of continuing education programming and mentoring the behaviours of current pharmacists. It does not present an argument for reduction in use or diminishment of other leadership theories, many of which have at least some overlap with transformational leadership. Rather, emphasis on transformation leadership might be one of many solutions to challenges plaguing the profession currently, with some sense of negativity and challenging workplace conditions among many pharmacists; support personnel and drug shortages; and a need for more collegial citizenship behaviors and stronger organizational culture. Transformative leadership behaviors and communication, versus others particularly more transactional in nature, envisage a future for the entire profession as well as for the individuals who comprise them, articulate the value of the contributions made by the employee, and help imbue a sense of professional identity. These are things sorely needed in the modern workplace and are either explicitly stated or tacitly implied in educational standards and professional competencies. A recent study on transformational leadership as measured by the Multifactorial Leadership Questionnaire (MLQ) found more parsimonious structures toward the definition of transformational leadership and the outcomes resulting from its use, which actually makes it easier to discern and thus even more applicable to incorporate into models of pharmacy education and practice. The time to further study and employ transformational leadership is now.

Transformational Leadership and Climate of Trust: Mediating Role of Organizational Justice

Despite universal agreement on the consequences of the organizational trust climate, little attention has been given to studying its determinants. This study aimed to investigate the role of managers’ transformational leadership behavior in developing trust climate in the hotel industry. Based on the social exchange theory, this study also examined the mediation effect of organizational justice in the relationship between managers’ transformational leadership and trust climate. Data were collected from 323 full-time employees engaged in three-star Bangladeshi hotels. The study employed a PLS-SEM approach to test the hypotheses. Results exposed the significant impact of managers’ transformational leadership on the hotels’ trust climate, and organizational justice mediates the aforementioned relationship. These findings highlight the role of managerial transformational leadership and organizational justice in developing and nurturing a climate of trust. Based on the results, the study offers theoretical and practical implications, along with further research directions.

The effect of athermal omega on the transformation behaviour of Ti-24Nb-4Zr-8Sn (wt%)

Ti-Nb based alloys are candidate materials for orthopaedic and orthodontic applications due to a low elastic modulus and superelastic properties. However, many of these alloys are also susceptible to a transformation to the hexagonal ⍵ phase. When ⍵ is formed isothermally it can stiffen and embrittle the alloy, however, there is a limited understanding of the role it plays when formed athermally on cooling, with many conflicting statements made within the literature. As such, this study assesses the role of athermally formed ⍵ on the superelastic behaviour and elastic modulus of the exemplar superelastic alloy, Ti-24Nb-4Zr-8Sn. It was found that the ⍵ phase raised the modulus and the stress required for superelastic behaviour. This highlights the need to design alloys resistant to both forms of the ⍵ phase, for low modulus superelastic alloys to be produced.

A high-performance TRIP Mg-Sc-Zn alloy enhanced by fine grain strengthening and nano-precipitate strengthening

The Mg–Sc alloys have attracted considerable attention from researchers due to their martensitic transformation behavior. However, the relatively low yield strength limits their practical application. Thus, Zn alloying combined with annealing treatment was used to improve the mechanical properties by modulating its microstructure. Zn alloying can effectively delay the recrystallization rate and refine the grain size of the alloy. The β/α intensity ratio and grain size of β phase increase with the increasing annealing temperature. When the annealing temperature is 600 °C, the major phase is β-Mg-Sc with minor α-Mg-Sc, ScZn and Mg3Sc phases. Further increasing the temperature to 650 °C would lead to the dissolution of ScZn and Mg3Sc phases into the matrix, resulting in smaller precipitations. The Mg-Sc-Zn alloy annealed at 600 °C for 60 min owns the best comprehensive mechanical properties, with yield strength, ultimate tensile strength, and elongation of 307.2 MPa, 330.5 MPa, and 21.1%, respectively. Further TEM analysis reveals that fine grain reinforcement, precipitation reinforcement, and stress-induced martensitic transformation during tensile deformation are the main factors for the enhancement of strength and ductility in this alloy.

Effect of chloride ions on the reactive species change pathway and removal performance in the MW/Co2+/PMS process

Efficient removal of refractory organic matter is the focus of research in the treatment of actual wastewater with Peroxymonosulfate-based advanced oxidation processes(PMS-AOPs). However, the high concentration of chloride ions (Cl−) ubiquitously present in wastewater changes the reactive species (RS) present in the process, and the mechanism of this change is still not clear. This study investigated the effects of Cl− on the transformation behavior of RS and treatment performance under microwave (MW) combined with cobalt ions (Co2+)-activated PMS. The results showed that increasing the Cl− concentration can enhance the removal performance of the MW/Co2+/PMS process for ammonia (NH4+-N), accompanied by the production of nitrate nitrogen (NO3-N), monochloramine (NH2Cl) and dichloramine (NHCl2), which was related to the transformation of existing reactive oxygen species (ROS, •OH and SO4•−) into reactive chlorine species (RCS), with hypochlorous acid (HClO) as an important intermediate. Cl− can generate HClO through free radical oxidation (•OH and SO4•−) dominance and non-free radical oxidation (PMS and Co3+) promotion, and the heat transferred by MW can further trigger conversion between HClO and PMS, thereby changing the distribution of RS. Increasing the dosage of PMS and the dosage of Co2+ promoted the transformation of Cl− to reactive species in the MW/Co2+/PMS process. At MW power=160W, [Co2+]=17.5μM,[PMS]=10mM, and [Cl−]=17mM, the maximum cumulative [HClO] reached 1910.97μM, and the decay rate was 0.1815 min-1.The macromolecular organic matter in aqueous environment competes with ammonia for the RCS. Through regulating [Cl−] in mature leachate, RCS has a certain oxidation effect to organic matter, but its limited oxidation ability leads to a decrease in the mineralization effect.

Comparison of Pb adsorption and transformation behavior induced by chicken manure and its DOM in contaminated soil

Organic fertilizer derived from animal manure can significantly improve soil fertility. However, limited research has investigated the capacity of exogenous organic fertilizer dissolved organic matter (DOM) to migration and transform heavy metals. In this study, the effect of chicken manure organic fertilizers with different maturity and their DOM on changes of Pb bioactivity was evaluated and the role of soil environmental factors driving the changes was determined through soil incubation, adsorption and leaching experiments. The FTIR results indicated that DOM derived from farmhouse chicken manure organic fertilizer (FCMD) contained more protein-like compounds and low maturity, while DOM from commercial chicken manure organic fertilizer (CCMD) contained more humic/fulvic acid and high maturity. FCMD and CCMD reduced the content of RES-Pb by 16.3–27.52 % and 6.66–13.98 %, respectively. And the effects of organic fertilizers and their DOM on Pb migration and activation follow the order of FCMD> CCMD> CK> commercial chicken manure organic fertilizer (CCM)> farmhouse chicken manure organic fertilizer (FCM). FTIR analysis showed that FCMD was primarily composed of aromatic unsaturated functional groups, and its adsorption capacity for Pb2+ was significantly lower than that of FCM. In addition, the application of FCMD significantly altered the physicochemical properties of soil and promoted the migration and leaching of Pb. FCMD not only causes the soil Pb2+ to be released into the effluent but also activates Pb from the stable form into the active form. In summary, animal manure with lower maturity has a risk to activate heavy metals and should be applied with cautions.

A Voyage of Discovering the Role of Principal Transformational Leadership Behaviour on EFL Teacher Psychological Well‐Being and Success

ABSTRACTAligning with the principles of positive psychology, a critical aspect that has gained prominence in academic territory over the past 2 decades is the concept of well‐being. And the recent scholarly articles have underscored the centrality of teachers' psychological well‐being (PWB). Given that the well‐being and success of teachers are contingent upon their workplace environment, external factors such as the behaviours of the principals wield considerable influence over them. In alignment with this premise, the present investigation sought to scrutinise the structural interplay between principal transformational leadership behaviours (TLB), well‐being and success within a cohort of 520 Chinese English as a Foreign Language, who were selected through convenience sampling. After the distribution of three self‐report scales among the participants to assess their perceptions of principals' behaviour, PWB and success, structural equation modelling (SEM) was utilised for statistical analysis to evaluate the hypothesised model. The outcomes of the analysis revealed that principal TLB explained 62% of the variance in the participants' success and 57% of the variance in their PWB. The implications of these findings for the extant literature are deliberated upon, leading to recommendations for policymakers and practitioners based on the results.

The Common Expression of INSM1 in HPV-related Oropharyngeal Squamous Cell Carcinomas Is Not Associated With True Neuroendocrine Transformation or Aggressive Behavior.

INSM1 has rapidly emerged as a robust marker for neuroendocrine (NE) differentiation, prompting the use of INSM1 as a standalone marker for NE differentiation in various sites. INSM1 staining could be an especially practical tool for evaluating HPV-associated oropharyngeal squamous cell carcinoma (HPV-OPSCCs) because high-grade NE transformation may be exceedingly difficult to recognize on morphologic grounds alone, even though it portends highly aggressive clinical behavior. The purpose of this study was to determine the incidence of INSM1 expression in HPV-OPSCC and study its role in determining NE transformation and clinical aggressiveness. Forty-six consecutive nonselected HPV-OPSCCs were stained with INSM1 and synaptophysin. In addition, 2 clinically matched cohorts of aggressive (n=28) versus nonaggressive (n=26) HPV-OPSCCs were retrospectively stained with the INSM1 and synaptophysin to determine the prognostic significance of INSM1 staining. In all, 42% of HPV-OPSCC showed positive INSM1 staining, but synaptophysin was not co-expressed in even a single case. In selected cases based on clinical behavior, INSM1 staining was observed more frequently in nonaggressive than aggressive tumors (50.0% vs. 21.4%, P=0.03). INSM1 expression is a common finding in HPV-OPSCC and is usually not linked with true NE transformation or aggressive behavior. Indeed, INSM1 expression is more commonly observed in nonaggressive cancers. Reliance on INSM1 staining alone in recognizing NE differentiation in HPV-OPSCC could be calamitous.

Microstructural evolution and phase transformation behavior of Ni-Ti alloys prepared by accumulative roll bonding-deformation diffusion process

Ni-Ti shape memory alloys were prepared by accumulative roll bonding-deformation diffusion (ARB-DD) process. Effects of deformation heat treatment on the microstructural evolution and phase transition behavior of ARB-DD Ni-Ti alloy were investigated by thermodynamic calculations, and the intrinsic mechanism was revealed. The results show that strong shear is induced by intensified plastic flow of the metal at the interface, resulting the interfaces engage with each other. The simultaneous opening and cross-tangling of multi-directional dislocations leads to the dislocation cells and Taylor lattice interact near the interface, and the compounds are preferentially formed. The ARB-DD treatment resulted in a one-step phase transition for the Ni-Ti alloy. After deformation heat treatment, R-phases appear and the phase transition is transformed into two-step. During heating and cooling the phase transitions are B19’→R→B2 and B2→R→B19’, respectively. The thermal hysteretic temperature increases and reaches 57.0 °C. The microstructure transforms from dislocations to nano-twin. A lattice distortion zone with a width of about 10 nm exists at the interface between precipitates and the matrix. It reduces the energy barrier required for phase transformation, leading to stabilization of the B2 phase and de-stabilization of the B19’ phase. Eventually, a wider temperature interval for the phase transformation is obtained. This process is an effective way to prepare Ni-Ti alloys with favorable shape memory effect.

Modeling Microstructure Development upon Continuous Cooling of 42CrMo4 Steel Grade for Large-Size Components

42CrMo4-type steel grades are widely used in a great variety of components that require ad hoc mechanical properties. However, due to the dimensions of large components and the previous thermomechanical treatments, the presence of heterogeneities in the chemical compositions are expected to impact those mechanical properties. In the present work, a detailed analysis of phase transformation behavior upon cooling was carried out through a dilatometry test on samples of 42CrMo4 belonging to a component that has a non-homogeneous chemical distribution. The analysis of the dilatation signals and the quantitative metallography shows a rather complex behavior depending on the cooling rate as well as on the region of observation. Two different phase transformation models based on Li’s approach were applied to the present composition to determine the CCT curve as well as the fraction of the microconstituents. An extensive discussion was carried out on some aspects about Kirkaldy-based approaches that need to be improved so as to attain more reliable quantitative results when modeling phase transformations in heterogenous systems.

Leading Knowledge Exploration and Exploitation in Schools: The Moderating Role of Teachers’ Open Innovation Mindset

Aim: The purpose of this paper is to identify teacher-level latent profiles of open innovation mindset and explore how these profiles moderate the effects of leader-member exchange on their exploitation and exploration activities. We also aim to investigate the indirect effects of principal transformational leadership on exploration activities via leader-member exchange. Research Design: Using a sample of 3,075 teachers working in 261 schools from 12 provinces across Türkiye, this study, first, employed a moderation analysis with latent profiles variables and, second, conduct a two-level structural equation model. Findings: Latent profile analysis produced three types of teacher mindset profiles: growth, average, and fixed. Findings indicate the quality of the dyadic exchange with the school principal did not influence engagement in exploitation activities of teachers with a growth mindset, whereas it contributed to the exploration activities of those teachers. Our results showed that when teachers perceived that their principal exhibited a higher level of transformational leadership behavior, they were more likely to have a higher leader-member exchange, which in turn increased the teachers’ exploration behavior. Implications: This study highlights both exploitative and explorative activities are facilitated by high-quality work-related social processes within the school, and we need to recognize affective and relational contexts in the schools, as they are primarily social institutions.

On the effect of the processing parameters in microstructure and thermomechanical properties of LPBF NiTi shape memory alloys

Recent studies have shown that variations in the parameters of the laser powder bed fusion (LPBF) process significantly impact the microstructure and thermomechanical properties of NiTi shape memory alloys (SMAs). Understanding how parameter selection influences the final NiTi SMA properties enables the strategic design of additively manufactured (AM) components with tailored mechanical and transformation behavior, suitable for specific applications in a plethora of scientific fields. However, the connection between processing and thermomechanical properties of NiTi SMAs is still not completely understood. This study investigates the effects of AM parameters laser power (72–185 W), scanning speed (668-1739 mm/s), and hatch spacing (28–85 μm) on a near equiatomic NiTi powder. Low porosity levels are found in the samples additively manufactured (AM) with the different LPBF parameter combinations. The findings also reveal that transformation temperatures and nickel evaporation trends correlate directly with volumetric energy density (VED). Additionally, the amount of Ti2Ni precipitates increases with higher VED. Thermal cycles under constant stress, training, and two-way shape memory effect tests have been performed; the results demonstrate a strain recovery ratio of 2–3.5% for most of the samples. The results arising from this study pave the way for the engineering of customized materials with tailored properties from the same alloy metal powder.

Multimodal assessment of mechanically induced transformation and damage in TRIP steels using X-ray nanotomography and pencil-beam diffraction tomography

A comprehensive multimodal measurement environment integrating X-ray computed tomography (CT) and special X-ray diffraction (XRD) using a collimated beam has been developed and was applied for the first time to investigate martensitic transformation and damage behaviour in transformation-induced plasticity (TRIP) steels. The transformation and damage behaviour of numerous γ grains were analysed individually to understand the behaviours and to identify the factors controlling these processes.A transition was observed from a stress-assisted transformation in the early loading phase, controlled by mechanical driving forces, to a strain-induced transformation controlled by dislocation density. A characteristic reversal in the transformation rate was observed whereby γ grains with a crystallographic orientation that initially undergo rapid transformation due to high mechanical driving force underwent a sudden deceleration of transformation. Conversely, γ grains with an orientation that initially underwent gradual transformation rapidly completed transformation. The preceding hard phase inhibited the transformation of neighbouring γ grains through the triple effects of reducing stress triaxiality, relaxing stresses and constraining plastic deformation.The growth of pre-existing voids was modest, and material damage was dominated by voids that were newly formed during deformation from α′ grains. The initiation and progress of damage were influenced by the combined effects of the γ grain morphology and their interaction with surrounding α′ grains. The complexity of the local morphology governed the martensitic transformation and damage behaviour, and geometrical parameters were identified as highly sensitive indicators for describing this phenomenon. Finally, industrial measures to design damage-resistant TRIP steels based on these research findings are discussed.

A deep insight of re-entrant martensitic transformation mechanism in Co2Cr(Ga,Si) shape memory alloys

Co2Cr(Ga,Si) shape memory alloys have a wide application temperature range due to the unique re-entrant martensite phase transformation (RMT) behavior. Nevertheless, the microscopic mechanism of RMT remains elusive and unsystematic. The heart of this investigation lies the comprehensive exploration of phase stability, phase transformation path, and martensite slip direction during RMT from martensite (D022-PM) to austenite (L21-FM). In this work, we systematically investigate the re-entrant martensitic transformation of Co2Cr(Ga,Si) SMAs using first-principles methods for the first time. Firstly, the density of states (DOS) calculation indicates that the stability of L21-FM is higher than D022-PM. The charge density calculation further indicates that the bonding strength between Co atoms and Cr (Si) atoms in the L21-FM phase is the highest. In addition, Fermi surface calculation further reveals that phase instability is due to the Fermi surface nesting caused by electron-phonon coupling. Moreover, the minimum energy path was calculated by the G-SSNEB method for the first time, which indicates the RMT can occur. Finally, the calculation of the elastic constants indicates that RMT is caused by the crystal plane slip of the D022-PM phase along the <110> direction. Our calculations provide the electronic-level and thermodynamic mechanism for RMT of Co2Cr(Ga,Si) alloy and shed some light on the revelation of the phase transformation mechanism.

Structure-Dependent Distribution, Metabolism, and Toxicity Effects of Alkyl Organophosphate Esters in Lettuce (Lactuca sativa L.).

This study provides a comprehensive investigation into the structure-dependent uptake, distribution, biotransformation, and potential toxicity effects of alkyl organophosphate esters (OPEs) in hydroponic lettuce (Lactuca sativa L.). Trimethyl, triethyl, and tripropyl phosphates were readily absorbed and acropetally translocated, while tributyl, tripentyl, and trihexyl phosphates accumulated mainly in lateral roots. The acropetal translocation potential was negatively associated with log Kow values. Trimethyl and triethyl phosphates are less prone to biotransformation, while a total of 14 novel hydrolysis, hydroxylated, and conjugated metabolites were identified for other OPEs using nontarget analysis. The extent of hydroxylation decreases from tripropyl phosphate to trihexyl phosphate, but multiple hydroxylations occurred more frequently on longer chain OPEs. Further comparative toxicity test revealed that hydrolyzed and hydroxylated metabolites have stronger toxic effects on Ca2+-dependent protein kinases (CDPK) than their parent OPEs. Dibutyl 3-hydroxybutyl phosphate particularly induces upregulation of CDPK in lateral roots of lettuce, probably associated with adenine reduction that may play an important role in the self-defense and detoxification processes. This study contributes to understanding the uptake and transformation behaviors of alkyl OPEs as well as their associations with a toxic effect on lettuce. This emphasizes the necessary evaluation of the environmental risk of the use of OPEs, particularly focusing on their hydroxylated metabolites.

The Transformative Teaching Practice of Teachers and Cultivation of 21st Century Skills of College Students in Selected Sports Universities in China

This study aims to explore the impact of teachers' transformative teaching practices on college students' mastery of 21st-century skills, with a focus on the teaching dimensions of "Personalized Considerations" and "Inspiring People," as well as the students' mastery of "Professional Skills" and "Life Skills." By analyzing students' assessments of their proficiency in 21st-century skills, the research demonstrates a significant positive correlation between transformative teaching behaviors and students' skill mastery. Specifically, the ability of teachers to motivate and provide personalized support significantly enhances students’ performance in learning, life, literacy, and professional domains. The data analysis revealed that students generally rated their mastery of 21st-century skills, including learning, life, literacy, and professional skills, as "agree," indicating a moderate level of manifestation. Additionally, differences in students' skill levels across gender, age, and grade level were found to be insignificant. However, the impact of transformative teaching practices on students' skill development was notably significant, particularly in the areas of "Charm Influence" and "Intellectual Stimulation." Regression analysis further highlighted that "Personalized Considerations" and "Inspiring People" teaching styles are strongly associated with students' mastery of 21st-century skills, especially in enhancing "Life Skills" and "Professional Skills." The proposed intervention program, developed from this study, aims to strengthen teachers' transformative teaching abilities to improve students' mastery of professional and life skills. Through personalized support and motivational guidance, college students will be better equipped to face future challenges in both their personal and professional lives. This study provides practical recommendations for educators to enhance teaching strategies to more effectively cultivate students' core 21st-century skills.

Interdiffusion mechanism between EB-PVD deposited CoCrAlY bond-coat and superalloy substrate under high-temperature oxidation service conditions in gas turbine

The interdiffusion mechanism between EB-PVD deposited CoCrAlY coating and superalloy substrate under high-temperature oxidation atmosphere in actual gas turbines was investigated both experimentally and through thermodynamics and kinetics simulation. The interdiffusion behavior differs at different regions of blade due to the different service temperatures. The elemental interdiffusion and phase transformation behavior were investigated and discussed. Needle-like topologically close-packed phase and σ-CrCoNi phase have precipitated within the secondary reaction zone due to the γ→γ’ transition and the uphill diffusion of Cr, W, and Mo. Decreasing the Co content in the MCrAlY bond-coat can inhibit the interdiffusion behavior to a certain extent.

Investigations of Metallurgical Differences in AISI 347 and Their Influence on Deformation and Transformation Behaviour and Resulting Fatigue Life.

Due to variations in chemical composition and production processes, homonymous austenitic stainless steels can differ significantly regarding their initial microstructure, metastability, and thus, their fatigue behavior. Microstructural investigations and fatigue tests have been performed in order to evaluate this aspect. Three different batches and production forms of nominally one type of steel AISI 347 were investigated under monotonic tensile tests and cyclic loading under total strain and stress control in low and high cycle fatigue regimes, respectively. The deformation induced α'-martensite formation was investigated globally by means of in situ magnetic measurements and locally using optical light microscopy of color etching of micrographs. The investigation showed that the chemical composition and the different production processes influence the material behavior. In fatigue tests, a higher metastability and thus a higher level of deformation induced α'-martensite pronounced cyclic hardening, resulting in significantly greater endurable stresses in total strain-controlled tests and an increase in fatigue life in stress-controlled tests. For applications of non-destructive-testing, detailed knowledge of a component's metastability is required. In less metastable batches and for lower stress levels, α'-martensite primarily formed at the plasticization zone of a crack. Furthermore, the formation and nucleation points of α'-martensite were highly dependent on grain size and the presence of δ-ferrite. This study provides valuable insights into the different material behavior of three different batches with the same designation, i.e., AISI 347, due to different manufacturing processes and differences in the chemical composition, metastability, and microstructure.

Transformation behavior of ω/α″ precipitates during aging and their influences on tensile properties in Ti-3Al-5Mo-4.5 V alloy

The metastable ω and α″ in titanium alloys have a significant impact on the subsequent α precipitates and the final mechanical properties. Herein, the microstructure transformation of coexisting ω/α″ during aging and their effects on tensile properties have been systematically investigated in Ti-3Al-5Mo-4.5 V (wt%) α/β titanium alloy. The results demonstrate that the secondary phase within the β-transformed (βtrans) grain evolves from embryonic ω + α″ to isothermal ω + α″, and ultimately transforms to secondary α (αs) with the aging temperature ascending from 300 °C to 550 °C. As embryonic ω transforms to isothermal ω, the yield strength increases from 1130.0 ± 14 MPa to 1259.5 ± 5.5 MPa with weak elongation due to the excellent strengthen effect of undeformed isothermal ω. After aging at 550 °C, coexisting micron-scale αp and nanoscale αs microstructures lead to enhanced elongation (increase by 93.7 %), sacrificing only 21.7 % yield strength. Both <a> and <c + a> dislocations are simultaneously presented in micron-scale αp grain, while nanoscale αs plates act as effective obstacles for dislocation motion resulting in accumulation of dense dislocations near the β/αs interfaces. This work provides new insights on strengthening strategy and developing new Ti-alloys.

Giant energy density with ultrahigh efficiency achieved in NaNbO3-based lead-free ceramics with polymorphic antiferrodistortive polar nanodomains

The development of dielectric ceramics with simultaneously high energy-storage density (Wrec) and efficiency (η) for capacitive energy storage poses a significant challenge. Herein, an effective strategy to achieve ultrahigh comprehensive energy-storage performance via designing polymorphic antiferrodistortive polar nanodomains is proposed, successfully realizing a giant Wrec of ∼7.5 J/cm3 with an ultrahigh η of ∼94 % in (0.9-x)NaNbO3-0.1BaZrO3-xBi(Mg0.5Ti0.5)O3 ((0.9-x)NN-0.1BZ-xBMT) lead-free ceramics at x = 0.08. The studied ceramic also exhibits excellent temperature-insensitive charge–discharge performances of high power density ∼204 ± 3 % MW/cm3, high discharge energy density ∼3.7 ± 3 % J/cm3 and fast discharge rate < 60 ns within 25–150 °C. The observation of ex-/in-situ piezoresponse force microscopy and transmission electron microscope reveals that polar nanodomains with multiple antiferrodistortive FE symmetries and diverse scales exhibit dissimilatory transformation behavior into FE microdomains during electric field loading/unloading, being responsible for a low-hysteresis polarization-field response with a near-zero remnant polarization and a high maximum polarization. Meanwhile, optimized bandgap structure and grain morphology contribute to the enhanced ceramic resistivity and conductivity activation energy as well as suppressed leakage current, resulting in significantly improved dielectric breakdown strength. These results demonstrate a feasible strategy for developing novel high-performance dielectric ceramics for high-efficiency capacitive energy storage.
