The goal was to optimize inter-laminar bonding during the AFP lay-up process and provide a model for the interlayer bonding of uncured prepreg tapes during this process. The shear strength of the interfacial bonding plays a pivotal role in the formation of planar and non-planar deformations during the automated fiber placement (AFP) process. The quality of this bonding has a significant effect on the quality of the manufactured parts. Besides, the bonding strength is interconnected with various AFP process parameters including compaction roller, feed rate, temperature, and dwell time. Hence, a systematic series of experimental studies are conducted to investigate how changes in process parameters affect the shear strength of single lap joint (SLJ) specimens produced under various process conditions. To fabricate the single-lap joint samples under different conditions, an in-house setup was developed to simulate the AFP process allowing us to control compaction force, feed rate, temperature, and dwell time during the process. The experimental results of the single lap joints indicate that the shear strength of the bonded prepreg tows is significantly influenced by the interaction among the process parameters rather than by their individual, isolated effects. Moreover, the responses of prepreg SLJs are simulated using the FE method. Through the comparison of numerical and experimental results, it will be clearly shown that the developed FE framework can act as a reliable approach for modeling the bonding layer between prepreg tapes.</p>","PeriodicalId":15489,"journal":{"name":"Journal of Composite Materials","volume":"59 12","pages":"1477-1491"},"PeriodicalIF":2.3,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11964850/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143795495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our experimental results show that this new strategy achieves excellent and stable pseudoelasticity with a recoverable ratio up to 85.5% larger than the highest value ever reported of 63.4% after 40 cyclic loading under a fixed strain of 14% due to the introduction of high-density austenite twins. The mechanisms of this promising property are revealed with the aid of subregional (grain boundary and grain interior) EDS, TEM, and in-situ BSE analysis. First, an appropriate forging and aging process introduces homogenous Ni₄Ti₃ precipitates, which reduce the energy dissipation required for one pseudoelastic loop from 4.49 to 2.48 J g⁻¹ by changing the phase transformation path and temperature. Second, the high-density austenite twins induced by deformed martensite twins during cyclic loading enhance the strength of the matrix. The reduced energy dissipation and stronger matrix improve the pseudoelasticity and its stability. We attribute these beneficial microstructure features to the specially designed processing routes: forging and subsequent aging. On the one hand, the dislocations induced by forging provide homogeneous nucleation sites, leading to Ni₄Ti₃ homogeneously precipitating during aging; on the other hand, the dense and homogeneously distributed precipitates accelerate the martensite transformation and increase the elastic modulus of the martensite, resulting in the advancement of the second stress plateau from 38% to 12%, in which part of the martensite is reoriented to generate multiple martensite variants, resulting in the formation of deformation <span><math><msub is=\"true\"><mrow is=\"true\"><mo is=\"true\">{</mo><mn is=\"true\">113</mn><mo is=\"true\">}</mo></mrow><mrow is=\"true\"><mi is=\"true\" mathvariant=\"normal\">B</mi><msup is=\"true\"><mn is=\"true\">19</mn><mo is=\"true\">′</mo></msup></mrow></msub></math></span> martensite twin.

Silicon carbide (SiC) is a third-generation semiconductor material with a wide band gap and excellent high-temperature stability and is regarded as a good candidate for overcoming the high-temperature intolerance of traditional pressure sensors. Currently, there are few reviews on recent advances in the synthesis, characterization, sensing mechanisms, design methodology, fabrication processes, operation, and application issues of SiC-based pressure sensors used under extreme application conditions. This review explores the following key topics: (i) key properties and special attributes of SiC materials; (ii) synthesis of SiC materials and thin films for high-temperature pressure sensor applications and processing of SiC materials, including etching, ohmic contacts, and bonding; (iii) recent development of SiC piezoresistive pressure sensors, including those based on silicon-on-insulator and all-SiC designs; (iv) recently reported SiC capacitive pressure sensors, including both 3C-SiC-based and all-SiC designs; and (v) advances in SiC-based fiber-optic pressure sensors.

In this regard, we have shown potassium intercalated (K+) carbon nitride (KPCN) as photocatalyst to unleash a new route, photo-valorization of FA to H2 in synergism with photo-redox cross-coupling of FA as C1 source with o-phenylenediamine (PDA) to produce benzimidazole (BA). It was realized that Pt/1KPCN produces 94 µmol.h-1.g-1 of H2 which was 23-folds higher compared to bare Pt/CN along with 50 % conversion of PDA to produce pharmaceutically important BA with AQY of 0.93 % at λ = 400 nm. Besides, charge transfer kinetics of Pt/1KPCN after K+ incorporation was ascertained by PL, photocurrent and solid-state EPR studies. Further the plausible mechanistic insights including basicity were thoroughly probed by scavenger-controlled experiments and CO2 TPD analysis, respectively. Apparently, Pt/1KPCN has shown the potential further to reduce in situ generated CO2 molecules (via dehydrogenation) to CO molecules. Thus, the current work provides a new milder sustainable protocol to expedite FA as renewable source not only to produce syngas, a solar fuel precursor for the Fischer-Tropsch synthesis (FTS) but also to nurture the carbon circular economy by producing high-end pharmaceutics.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"7 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143876333","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}

Herein the controlled assembly and optoelectronic tunability of 0D-2D heterostructures is demonstrated, employing DNA as a linking and template moiety for the modular assembly of metal sulfide nanoparticles (NPs) on MoS₂, with nanoscale control over their separation and ability to concomitantly assemble different kind of NPs on the same DNA template linker. The developed aqueous solution-processable approach permits the systematic modulation of charge carrier doping and trion formation in the transition metal dichalcogenide (TMD) in a non-destructive manner. Moreover, it allowed to tailor the photoinduced electrical response -with ultrahigh detectivity- of NPs-TMD phototransistors to different wavelengths, thanks to the concomitant presence of different nanoparticles by design.

Radiotherapy (RT) plays a crucial role, especially in treating locally recurrent rectal cancer and preserving anal function. However, its effectiveness is often limited by tumor hypoxia, particularly prevalent in hypoxic regions near the bowel wall in colorectal cancer. Hypoxia contributes to both radiation resistance and apoptosis resistance, compromising RT outcomes. To overcome hypoxia‐driven radiotherapy resistance, this work designs and engineers a radiotherapy‐sensitizing bioplatform for efficient cancer RT. It combines lanthanum oxide nanoparticles (La<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> NPs) with cyanobacteria, which produces oxygen through photosynthesis. This bioplatform uniquely reduces tumor hypoxia, enhances radiation deposition, and improves RT efficacy. La<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> NPs further enhance reactive oxygen species (ROS) production induced by radiation, triggering pyroptosis via the ROS‐NLRP3‐GSDMD pathway, while RT amplifies pyroptosis through GSDME, circumventing tumor apoptosis resistance. The further integrated thermosensitive hydrogels ensure precise localization of the bioplatform, reducing systemic toxicity and improving therapeutic specificity. Compared to conventional therapies, this dual‐action system addresses hypoxia, RT resistance, and apoptosis resistance more effectively. In vivo and in vitro hypoxia models validate its potent anti‐tumor efficacy, offering valuable insights for refining clinical treatment paradigms.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"130 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143875843","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}
