In this study, ZnO_x/SU-8 nanocomposite nanopillars with a diameter of 300 nm, fully infiltrated with a uniformly distributed, interpenetrating amorphous ZnO_x filler network, were synthesized via vapor-phase infiltration (VPI). In-situ uniaxial nano-compression tests revealed that the modulus of resilience of ZnO_x/SU-8 reaches ∼ 12 MJ/m³, which is an ultrahigh value among all engineering materials with comparable strength. In addition, the synthesis fidelity, inorganic infiltration depth, and mechanical performance were all significantly improved compared to VPI-synthesized AlO_x nanocomposites. Thermal stability, another key requirement for M/NEMS device materials operating under extreme environments, was also notably enhanced. Furthermore, partial crystallization of the amorphous ZnO_x fillers during annealing contributed to an additional increase in modulus of resilience, reaching up to ∼ 13.9 MJ/m³.

Annular dark field scanning transmission electron microscopy confirmed the presence of a new type of metastable η consisting of overlapping and laterally intertwined ORR⁻¹ and OR⁻¹R sequences of stacked R and O units across the platelet thickness.

Here, we demonstrate a rapid hot-compression bonding strategy that uses a niobium (Nb) interlayer to control interfacial reactions and produce a high-strength joint between 18Ni350 maraging steel and AlNbTi₃Zr_1.5 HEA. The effects of bonding temperatures on the interfacial microstructures, mechanical properties, and fracture mechanisms were systematically investigated. An exceptional joint tensile strength exceeding 1 GPa was achieved at an optimal bonding temperature of 850 °C. This is attributed to the formation of a continuous, ultra-thin nanocrystalline Fe₂Nb reactive layer (RL) at the 18Ni350/Nb interface, coupled with a well-bonded, intermetallic-free HEA/Nb interface. However, increasing the temperature to 1000 °C thickens the Fe₂Nb RL to over 300 nm and promotes grain coarsening, reducing the joint strength to 747 MPa. Correspondingly, the fracture mode transitions from a complex path involving both interfaces and the interlayer at low temperatures to preferential fracture along the thickened Fe₂Nb RL at 1000 °C. These findings reveal the central role of intermetallic design in governing interfacial performance, demonstrating that controlling interfacial nanostructures is a critical strategy for fabricating high-strength dissimilar joints.</div></div>","PeriodicalId":383,"journal":{"name":"Materials & Design","volume":"263 ","pages":"Article 115540"},"PeriodicalIF":7.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146185997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stronger hydrogen bonds formed in PA1012 powders upon incorporating a thermoplastic phenolic resin (PF), leading to broader processing windows and lower melt viscosities, allowing the fabrication of parts with fewer defects and superior mechanical performance. Incorporating 5–15 wt% PF reduced the water absorption of PA1012 parts by 54–57 %, thereby largely improving their mechanical and dimensional stabilities in humid conditions. Moreover, PF suppressed the post-condensation and deterioration of unfused powders. Therefore, strengthening the hydrogen bonding interactions in polyamide powder offers a simple strategy to enhance the part performance in humid conditions and promote the sustainability of laser additive manufacturing.</div></div>","PeriodicalId":383,"journal":{"name":"Materials & Design","volume":"263 ","pages":"Article 115659"},"PeriodicalIF":7.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146185814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that the Fickian model was only applicable under low humidity and temperature conditions. Although the dual-stage model fit well, its assumption of “independent diffusion of bound water” contradicted experimental observations. The Langmuir model also achieved high fitting accuracy. This study also established temperature–humidity-dependent functions for EMC moisture-related parameters.

Under medium humidity, the moisture content increased linearly with humidity, while the transformation probability and diffusion coefficient decreased linearly.

A resistive pressure sensor was fabricated by spraying a graphene/MXene composite solution onto polyurethane (PU) nanofibers film. Additionally, a resistive temperature sensor was also coupled onto the pressure sensor by combining graphene/MXene with poly(3,4-ethylenedioxythiophene):poly (styrenesulfonate) (PEDOT:PSS), forming a dual-functional sensor.

This dual-functional sensor can achieve precise temperature detection with a resolution of 1 °C.

Here, we report the design and characterization of a minimal peptide-based material obtained through abiotic thermal polymerization, exhibiting spontaneous and persistent electrical oscillations under constant environmental conditions.

Electrical measurements demonstrate autonomous oscillatory signals arising under constant environmental conditions and in the absence of external stimulation. Simultaneous dynamic light scattering and electrical measurements reveal a direct correlation between electrical oscillations and aggregation–disaggregation dynamics, indicating that the electrical activity emerges as a collective property of chemically heterogeneous peptide ensembles rather than from individual molecular species.
