Porous piezoceramics exhibit enhanced voltage output response, demonstrating significant potential for applications in piezoelectric sensors. In this study, four types of PZT-based porous ceramics with triply periodic minimal surface structures were fabricated using digital light processing (DLP). By controlling the powder morphology and debinding process, composite porous ceramics with coexisting periodic macropores and random micropores, as well as simple porous ceramics with only periodic macropores, were prepared. The results reveal that random pores more effectively reduce the permittivity, however, the increased coercive field and reduced breakdown strength lead to a significant deterioration in the piezoelectric coefficient (d33). In contrast, simple porous ceramics, featuring dense ceramic phases, exhibit higher breakdown strength and lower coercive field, enabling more effective poling. Notably, the Gyroid structure achieves a high d33 of 585 pC/N, comparable to bulk ceramics, while the relative permittivity is significantly reduced to 706. Consequently, an outstanding piezoelectric voltage constant (g33) of 93.3 mV·m·N–1 and a high piezoelectric energy harvesting figure of merit of 54.6 × 10–12 m2/N are achieved, far surpassing conventional random porous ceramics. These findings highlight that DLP technology and the development of artificial periodic porous ceramics provide a promising pathway for the design of high-performance piezoelectric devices.

Traditional indoor formaldehyde (HCHO) treatment technologies often rely on light or thermal fields to supply catalytic energy, limiting their practical application in indoor environments. This study presents an in-situ growth strategy for uniformly loading δ-MnO2 onto diatomite to achieve efficient room-temperature catalytic oxidation of HCHO. The size of δ-MnO2 on the δ-MnO2/diatomite (50%MD) composite is significantly reduced, forming a microporous structure, with δ-MnO2 nanoflowers uniformly dispersed on the diatomite surface. The optimal 50%MD composite exhibits a hierarchical pore structure, greatly enhancing catalytic site exposure, and achieving a HCHO removal rate of 98.0%. The enhanced performance is attributed to the interaction between diatomite and δ-MnO2, which optimizes the particle size and dispersion of δ-MnO2, increases the Mn3+ content, and improves the surface oxygen activity of δ-MnO2. In-situ DRIFTS analysis demonstrates that 50%MD possesses the highest adsorption capacity of H2O, which is conducive to accelerating the conversion of intermediates and promoting the desorption of CO2. Moreover, SEM-FIB analysis intuitively reveals efficient H2O mass transfer on 50%MD to aid hydroxyl groups (–OH) regeneration. This work establishes a cost-effective, energy-free, and scalable strategy for indoor HCHO purification via coupled mineral-enabled transport engineering and interface-driven MnO2 activation.

Current (photo)electrolysis for solar hydrogen generation is limited by its dependence on noble- or less abundant transition metal catalysts. Proton exchange membrane (PEM) water electrolysis is highly suitable for coupling with intermittent renewables like solar power due to its high power density and load-following capability [1]. A critical drawback is the reliance on iridium-based oxides as the anode catalyst for the oxygen evolution reaction (OER). Despite their unmatched stability under harsh acidic conditions, the global supply of iridium is severely limited (7–8 t per year). Current catalyst loadings (2–4 mgIr·cm–2) restrict the maximum annual PEM electrolyzer installation capacity to approximately 10 GW [2]. Two fundamental strategies address this issue by pursuing next-generation electrocatalysts: (1) metal dilution/structural engineering to maintain performance with less iridium, and (2) exploring catalysts based on abundant elements. Both strategies necessitate truly atom-efficient catalyst synthesis — at minimized concentrations in the case of iridium — and require maximizing the contribution of the catalytic sites in order to meet the performance needs. The synthesis of such systems also involves support materials, which the catalysts are grafted onto at the atomic-to-nano-scale. Despite high-precision synthesis methods, diverse active site structures can exist within these complex systems, as structural uniformity is heavily influenced by catalyst–support interactions and the specific conditions of synthesis and operation. Due to the above complexities, catalysts should be assumed to be structurally non-uniform until shown otherwise, as postulated by Bates [3].

Complex lead-based perovskites with the general formula Pb(Bx'B1-x")O3, represent an important class of antiferroelectrics beyond the prototypical PbZrO3 and NaNbO3. Depending on the combination of B-site species and the degree of cationic ordering, these materials exhibit a wide range of ferroic behaviors, spanning from antiferroelectric to (relaxor) ferroelectric responses. In this study, we investigate (Pb1-xBax)(Yb1/2Nb1/2)O3 polycrystals synthesized via a two-step processing route. Despite displaying antiferroelectric, ferroelectric, or nearly linear dielectric behavior at room temperature, all compositions exhibit double polarization hysteresis loops in proximity to a lower-temperature dielectric anomaly. This dielectric anomaly originates from the competition between antipolar and nanoscale polar regions, and shifts towards lower temperature with increasing Ba content, reflecting the suppression of long-range antiferroelectric ordering. Notably, a composition-invariant temperature scale, T∗, is identified and associated with the onset of static correlations among nanoscale polar entities, consistent with behavior reported in other complex Pb-based relaxor ferroelectrics. Superlattice reflections arising from antiparallel Pb2+ displacements persist above T∗, suggesting an intricate cation-ordering landscape requiring further investigation. These findings underscore the coexistence and competition of polar and antipolar instabilities in complex lead-based perovskites, and their pronounced sensitivity to chemical substitution, thermal fluctuations, and external electric fields.

Digital light processing (DLP) printing of PbZrTiO3 (PZT) ceramics is significantly hampered by the inherent high light absorption of the powder, leading to detrimental defects such as shrinkage and cracking, which severely compromise the final sensor performance. Herein, we propose a strategy to modulate the light absorption of PZT powder by mixing compositions calcined at different temperatures. By optimizing the mass ratio of P860 to P1150 to 1:9, we achieved a suspension with enhanced curing depth and rheological properties, enabling the fabrication of high-density ceramics with a piezoelectric constant of 470 pC/N. Furthermore, a sophisticated sandwiched piezoelectric sensor, architected with crossed square columns, demonstrated exceptional electromechanical performance, generating an open-circuit voltage of 278 V and a short-circuit current of 2.19 μA. This design conferred a piezoelectric sensitivity approximately 7 times greater than bulk counterparts. Remarkably, despite its compact size of merely 1.3 cm × 1.3 cm, this sensor still achieves a transmission power of 5.2 mW during underwater remote energy transfer over a distance of 400 mm. This work establishes a viable pathway for fabricating next-generation high-performance PZT piezoelectric sensors via advanced DLP processing.

Aromatic polyimide (PI) with high glass transition temperature (Tg) shows promise as a polymer dielectric for energy storage, but its rigid aromatic structure and electron delocalization cause significant conduction loss, degrading energy storage performance and breakdown strength (Eb) under high temperatures. Herein, we introduce a novel semi-alicyclic fluorinated polyimide (H-FPI) designed via a molecular engineering strategy that synergistically integrates bandgap and topological conformation modulation. Specifically, the alicyclic group elevates the lowest unoccupied molecular orbital (LUMO) while strong electron-withdrawing trifluoromethyl (CF3) substitution depresses the highest occupied molecular orbital (HOMO), creating a wide bandgap (4.2 eV). Concurrently, the chair-conformation alicyclic backbone and sterically bulky CF3 groups synergistically disrupt molecular planarity, reducing π-orbital overlap to suppress charge transfer while restricting chain mobility to yield a high Tg of 272 °C. Remarkably, H-FPI film delivers a high energy density of 6.02 J/cm3 with a superior breakdown strength of 626 MV/m at 200 °C, surpassing commercial PI and fluorinated polyimide (FPI) by 1261% and 55%, respectively. Furthermore, H-FPI film exhibits exceptional capacitor charge-discharge cyclability, enhanced mechanical robustness, and excellent thermal stability. This work establishes a new molecular design paradigm for organic capacitors in electrified transportation and smart grid systems requiring high-temperature working reliability.

Ultra-high temperature ceramics (UHTCs) exhibit ultra-high melting points and relatively high mechanical performance, making them ideal coating materials for extreme environment applications like hypersonic vehicles. Recently, novel design strategies of UHTCs coatings have been proposed, mainly including the composition and structural design. In this article, state-of-the-art approaches including multilayer and gradient UHTC coatings for enhanced mechanical and ablation resistance, surface engineering for the improvement of coating adhesion, materials and microstructural design for thermal insulation, laser ablation protection, and drag reduction were reviewed. Furthermore, advanced designing and fabrication techniques for UHTC coatings are also prospected, which can provide insights for the development of next-generation multi-functional UHTC coatings for harsh conditions.
