Nevertheless, its practical application is hindered by substantial dielectric loss and inadequate temperature/frequency stability. This study introduced co-doping with Sb5+ and Gd3+ to prepare (Sb0.5Gd0.5)xTi1–xO2 (SGTOx, x=0, 0.01, 0.02, 0.03, 0.05) co-doped TiO2 ceramics. By constructing electron-pinned defect clusters, synergistic optimization of a high dielectric constant and ultra-low dielectric loss was achieved. The SGTO0.01 ceramics exhibited outstanding comprehensive performance, possessing a high dielectric constant of 1.06×104 and an ultra-low dielectric loss of 0.011 at 1 kHz, along with excellent frequency stability (20 Hz – 1 MHz) and temperature stability (–150 °C to 260 °C, Δεᵣ < ±15%), as well as superior DC bias characteristics (0–26 V). X-ray photoelectron spectroscopy (XPS) and dielectric response analysis indicate that the synergistic doping of Sb5+ and Gd3+ promotes the formation of strongly coupled defect clusters. The defect dipole response constitutes the primary source of the high dielectric constant, while redundant internal barrier layer capacitance (IBLC) effects and electrode interface polarization are observed at medium-to-low frequencies. The electronic pinning effect of defect dipoles enhances electron localization and effectively suppresses long-range carrier transport. This study provides new insights into defect engineering for developing high-performance giant dielectric materials and clarifies the structure–property relationship between defect cluster configurations and dielectric performance in heterovalent co-doping systems.","PeriodicalId":16173,"journal":{"name":"Journal of Materiomics","volume":"20 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147586689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome these issues, we adopted a multi-element (Y, Mn, Mg) doping strategy to successfully construct a core-shell architecture. This design significantly suppresses the decay of the dielectric constant in the core under a DC bias. A systematic analysis was conducted on the effects of sintering atmosphere and annealing on the microstructure and dielectric properties. The results reveal that the sample Y-N, sintered in a reducing atmosphere, exhibits excellent DC bias stability. This can be attributed to its higher defect concentration, which effectively inhibits the migration of oxygen vacancies. Consequently, Y-N shows only a –0.61% decay rate of the dielectric constant at 2 V/μm, while achieving remarkable temperature stability (meeting the EIA X8R specification) and frequency stability (with a –2.1% variation from 1 kHz to 1 MHz). In contrast, samples annealed in air exhibit degraded DC bias stability at high electric fields due to shell thinning. This work provides valuable insights for the development of highly reliable dielectric materials for base-metal electrode MLCCs applications.","PeriodicalId":16173,"journal":{"name":"Journal of Materiomics","volume":"24 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2026-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147587756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

More importantly, the effective absorption bandwidth is broadened from 2.9 GHz to 4.1 GHz benefiting from the construction of electromagnetic synergy networks. Additionally, the radar cross section (RCS) value (29.14 dB⸱m2) evaluated by the computer simulation technology (CST) results for SiP2@Ni-S2 confirm the excellent dissipation ability.

Herein, a sandwich-structured SiC nanowire aerogel with gradient porosity was engineered through a one-step in situ growth strategy, combining a dense sub-micropore (< 1 μm) shell and a macroporous (10–360 μm) core. The nanoconfined pores of the shell suppress gas-phase thermal transport by limiting molecular collisions, while the air-entrapped macropores of the core minimize solid-phase conduction, synergistically yielding a low thermal conductivity of 0.05 W/(m·K), 33% lower than that of the homogeneous counterparts. The continuous gradient interface eliminates interfacial delamination and redistributes stress, achieving a strong mechanical resilience (11.2 kPa compressive strength) via shell-layer nanowire friction and elastic recovery (90% strain retention after 100 cycles) through core-layer dendritic flexibility. Single-crystal nanowires, stabilized by a self-passivating amorphous layer (∼20 nm), ensure structural integrity at 1400 °C with negligible oxidation. Furthermore, the hierarchical architecture facilitates broadband microwave absorption via gradient impedance matching and multiscale reflections. By integrating template-guided polymer conversion and catalyst-directed nanowire assembly, this work pioneers a scalable paradigm for multifunctional aerogels that combine extreme thermal insulation, mechanical durability, and microwave absorption properties, providing a transformative solution for next-generation aerospace thermal protection systems.","PeriodicalId":16173,"journal":{"name":"Journal of Materiomics","volume":"14 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2026-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147471135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
