Polymer-derived SiC-based ceramics have attracted great attention for EMW absorption owing to their tunable phase compositions and adjustable conductivity. However, their practical performance is often constrained by poor impedance matching and insufficient dielectric polarization and attenuation mechanisms. In the present work, ceramic heterostructures comprising MXene-derived TiC nanocrystals embedded in a predominantly amorphous Si-containing matrix were synthesized using polycarbosilane and Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> MXene as precursors. Microstructural and phase analyses reveal that most of the introduced MXene is converted in situ into nanocrystalline TiC, while the PCS-derived Si-containing matrix remains predominantly amorphous. The resulting multiphase ceramics exhibit abundant heterointerfaces and defect structures, which synergistically enhance interfacial polarization and dielectric loss while improving impedance matching. Therefore, the obtained multiphase samples achieve a minimum reflection loss of − 45.7 dB at 1.4 mm thickness and a broad 6.24 GHz bandwidth at a matching thickness of 1.7 mm. These results demonstrate that interface engineering via MXene incorporation is an effective strategy for tailoring microstructure and optimizing EMW absorption performance in polymer-derived ceramic systems.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":7220,"journal":{"name":"Advanced Composites and Hybrid Materials","volume":"9 5","pages":""},"PeriodicalIF":15.5,"publicationDate":"2026-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42114-026-02030-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148927918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study describes a novel 3D-printable bigel system designed to co-deliver hydrophilic epigallocatechin gallate (EGCG) and hydrophobic curcumin (Cur), aiming to address the multifactorial causes of impaired diabetic wound healing. The bigel matrix comprises two interpenetrating networks: a β-sitosterol/candelilla-wax oleogel and a chitosan-polyvinyl-alcohol hydrogel. Within these networks, curcumin is housed in the oleogel phase and EGCG in the hydrogel phase. The bigel’s unique bicontinuous structure imparts excellent mechanical properties and enhanced 3D printing characteristics compared to traditional single-phase gels. The excellent 3D printing performance can enable it to be applied to wounds such as ulcers where drug administration is difficult (not pressable or smearable). Moreover, the bicontinuous structure facilitates simultaneous release of both bioactive drugs and significantly improves cutaneous permeation, enabling deep penetration of drugs into wound tissues. Both in vitro and in vivo evaluations demonstrated that bigel-treated wounds healed faster and with superior quality compared to those treated with oleogel or hydrogel alone. RNA sequencing analysis identified key genes and signaling pathways (e.g., Wnt and MAPK) potentially involved in bigel‑mediated immune regulation. Subsequent Western blotting confirmed upregulated p‑ERK and β‑catenin protein expression, indicative of MAPK and Wnt pathway activation, thereby offering preliminary mechanistic insights.

However, achieving both high mechanical strength and good water resistance in magnesium oxychloride cement (MOC) remains challenging. Herein, we present an efficient biomimetic mineralization approach to fabricate a high-strength and water-resistant MOC-based adhesive. Specifically, polyamide polyamine compound (PPC) served as an organic template, facilitating the formation of densely interwoven phase 5 crystals within its polymer network. Sodium citrate (SC) regulated the formation of phase 5 hydration products via Mg<sup>2+</sup> chelation. The synergistic interaction between PPC and SC promoted the development of a compact organic-inorganic hybrid structure within the MOC adhesive, thereby enhancing its mechanical properties, bonding performance, and water resistance. The findings indicated that the MOC-SC-PPC adhesive exhibited significantly enhanced properties. Among the formulations, the MOC-SC-PPC/0.8 adhesive exhibited the highest compressive strength of 36.19 MPa after 7 days of curing, while the MOC-SC-PPC/0.2 adhesive achieved the highest softening coefficient of 0.86, indicating substantially improved water resistance. Moreover, the modified adhesive exhibited a prolonged setting time (from 108 min to 269 min), which is beneficial for practical construction applications. The MOC-SC-PPC/0.6 adhesive exhibited significantly improved wet bonding strength (0.85 MPa vs. 0.61 MPa) compared to the pure MOC adhesive, indicating enhanced water resistance and interfacial bonding performance.

Notably, oxygen vacancies at the SnO<sub>2</sub>/perovskite interface act as dominant nonradiative recombination centers, severely inhibiting device performance. While conventional interfacial passivation strategies have primarily focused on localized coordination by anionic anchoring groups, the role of π-conjugated anions in interfacial modifiers remains insufficiently understood. Here, a conjugated anion modulation is established by comparing potassium acetate (KAc) and potassium sorbate (KSb), which share identical K<sup>+</sup>–carboxylate frameworks but differ in anion conjugation, elucidating the contribution of the π-conjugation effect in interfacial defect suppression. Unlike the localized interaction of KAc, the π-conjugated framework of KSb enables more delocalized electronic interactions, contributing to spatially extended passivation from the buried interface into the perovskite region. These extended interactions enable favorable energy-level alignment and effective passivation of oxygen vacancies in SnO<sub>2</sub>, while also improving perovskite crystallinity and suppressing interfacial recombination. As a result, KSb-modified devices achieve an efficiency of 22.16% with an open-circuit voltage of 1.183 V and a fill factor of 84.30%, surpassing KAc and control devices. Unencapsulated KSb devices retain 97% of their initial efficiency after 1000 h under dark ambient storage and demonstrate improved film-level thermal stability.

The design of experiments (DoE) uses cell geometry parameters to examine the effects of uniform wall thickness, functionally graded thickness (FGT), and re-entrant angle on bending stiffness, strength, and specific energy absorption (SEA). The results show that the low re-entrant angles result in a stretch-dominated response, with high bending stiffness, strength, and progressive failure. Higher angles promote bending-dominated mechanisms. FGT further improves performance by combining high peak load with extended post‑peak deformation, leading to higher SEA than uniform‑thickness designs.

The multi-objective NSGA-II optimization results in a Pareto front that captures trade-offs to maximize the mechanical performances and SEA.

This study presents a feasible design strategy for developing novel lead-free shielding materials that combine high protective performance with wearability.</p></div>","PeriodicalId":7220,"journal":{"name":"Advanced Composites and Hybrid Materials","volume":"9 5","pages":""},"PeriodicalIF":15.5,"publicationDate":"2026-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42114-026-01970-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
