However, conventional MIC often yields structurally compromised films due to chaotic interfacial thermodynamics and incomplete layer exchange. Herein, a molecular-level engineering strategy is presented that utilizes buried self-assembled monolayers (SAMs) to remotely control the macroscopic phase transformation and crystallization kinetics during MIC with aluminum as the metal. By systematically tailoring the terminal functional groups of the SAMs at the buried interface between the Al/Si stack and substrate (glass), a distinct structure-property relationship is established: electron-withdrawing groups intrinsically stabilize the amorphous Si (a-Si) network and suppress segregation, whereas electron-donating groups facilitate silicon dissolution. Notably, the best-performing SAM with nucleophilic –NH2 terminal groups functions as a dual-role molecular template that drastically lowers the macroscopic crystallization barrier of the MIC system. By driving a highly directed and accelerated kinetic pathway, this monolayer substantially suppresses stochastic interdiffusion, yielding a highly segregated, continuous, and transfer-ready poly-Si film. Ultimately, this SAM-mediated paradigm advances the fundamental design of non-local phase transformations, establishing a scalable, material-driven pathway for next-generation flexible silicon electronics.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"37 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374625","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, a rigid epoxy-functionalized polysilsesquioxane hybrid resin is synthesized, followed by cross-linking with various amine curing agents through a high-efficiency synchronous thermal-moisture dual-curing route. The optimized EGSI coating crosslinked by isophorone diamine (IPDA) achieves a pencil scratch hardness of 9H and a nanoindentation modulus of 2.66 GPa. Viscoelastic characterization confirms a distinctive filler-free self-reinforcement effect originating from the siloxane skeleton; the glass transition becomes indistinct, and the optimized coating preserved ∼40% of its initial glassy storage modulus, corresponding to a remarkably high rubbery plateau modulus of ∼750 MPa up to 300 °C. Ball-drop impact tests support the effectiveness of the proposed rigid backing structural constraint mechanism. When coated on the rear face of 300 μm structural ceramic sheets, the EGSI layer elevates the maximum crack-free nominal drop energy to 63.9 mJ, representing a 233% enhancement compared with bare ceramics. Different from conventional front-side energy-absorbing coatings, this noninvasive rear-side reinforcement scheme avoids damaging the decorative exterior of ceramic components and enables low-cost upgrading of ordinary sintered ceramics to high shock-resistant grade. This study establishes a design approach for the tested systems and coating configuration optimization methodology for reinforcing brittle substrates, showing great application prospects in smartphone ceramic back covers, ultrathin glass panels, and other electronic protective components.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"13 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374618","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}

However, flexible electronic devices are prone to detaching under dynamic conditions or underwater environments, resulting in inaccurate and delayed signal transmission. This work employed a “one-pot method” to prepare a hydrogel (named DPE) with a three-dimensional network structure composed of [2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide (DMAPS), polyacrylic acid solution (PAA), and ethylene glycol dimethacrylate (EDMA). It demonstrates excellent wet-adhesion properties, superior swelling-resistant (swelling rate of 5.82%), water retention capacity (88.53%), self-healing properties, biocompatibility, and reliable detection of physiological signals both in air and underwater. Additionally, the hydrogel possesses a low modulus (7.62 kPa) and a good linear operating range (gauge factor = 4.41). Given these advantages, hydrogels are highly sensitive and reliable for monitoring human motion signals, transmitting Morse code, and acquiring bioelectric signals. At the same time, based on the electrical signals generated by the hydrogel bending at different angles, the hydrogel can also drive the robotic hand to perform actions. In addition, hydrogels are capable of capturing electromyographic (EMG) signals underwater and achieving 98.75% gesture recognition accuracy using deep learning algorithms. This multifunctional hydrogel opens up possibilities for the application of flexible wearable sensors in various environments and holds great potential for next-generation bioelectronic devices.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"14 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374619","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}

Biomaterial-based scaffolds have shown promising outcomes in terms of repair capacity; however, finding a robust scaffold system remains challenging in cartilage tissue engineering. In this study, silk fibroin porous microspheres were fabricated using the co-axial electrospraying technique, followed by ethanol treatment to induce crosslinking and enhance microsphere stability. Interestingly, we observed that while changing the ethanol concentration from 100% to 75% to crosslink the silk microsphere resulted in the formation of tunable micropores, with pore sizes up to 87 μm in nonporous microspheres and ranging from 80–200 μm in porous microspheres. Then, we seeded human adipose-derived mesenchymal stem cells (hAdMSCs) onto microspheres to evaluate cell adhesion and proliferation over time. The microspheres exhibited enhanced cell adhesion during in vitro cytocompatibility assessments. Notably, porous microspheres displayed superior cell migration compared to nonporous microspheres, attributed to their interconnected pore architecture. Additionally, hAdMSCs-laden microspheres were further studied for their chondrogenic potential under induction conditions, demonstrating cartilage-specific marker expression. Moreover, macroscopic observations and histological staining images showed cartilage regeneration in a rabbit cartilage-defect model, in which porous microspheres outperformed nonporous counterparts due to their enhanced nutrient transfer and host-scaffold integration. Together, these results suggest that silk fibroin microspheres can mimic the extracellular matrix microenvironment, support cell growth, and promote matrix accumulation for effective cartilage repair.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"17 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374623","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}

A crystalline, vacuum-deposited nitrogen-doped NiO (NiO:N) film deterministically templates a uniformly anchored SAM, while the reactive-atmosphere N2/O2 ratio used during pulsed laser deposition (PLD) simultaneously programs bulk hole density and interfacial anchoring chemistry. Nitrogen incorporation is proposed to act as a shallow acceptor that generates Ni3+ states and raises p-type conductivity, whereas the dense, pinhole-free template enforces uniform SAM coverage, fully suppressing the underlying substrate signal and minimizing surface hydroxyl groups relative to discontinuous nanoparticle films. Consequently, NiO:N/SAM-based PSCs achieve a 6.2% relative increase in power conversion efficiency (PCE) over pristine NiO nanoparticles, reaching one of the highest reported performances for vacuum-deposited NiO-based PSCs, with improved thermal and operational stability.

However, existing polarity-engineering approaches often fail to preserve high-quality contact interfaces because atomically thin 2D semiconductors are highly sensitive to fabrication processes. Here, we introduce an effective buffer-layer removal process that enables polarity transformation while preserving a high-quality contact interface. A thin semimetal layer (Bi or Sb) is deposited prior to high-work-function metal evaporation and subsequently removed by a wet chemical treatment that preserves a high-quality metal/semiconductor interface. Minimizing the contact angle of the rinsing solution suppresses wrinkle and bubble formations and reduces Fermi-level pinning. The same WSe2 transistors transform from semimetal-dominated n-type transport before treatment to high-work-function-metal-dominated p-type transport afterward. Monolayer devices exhibit a maximum two-terminal hole field-effect mobility of 313 cm2 V–1 s–1 after treatment, while also supporting a maximum electron mobility of 41 cm2 V–1 s–1 before treatment. These results demonstrate n-to-p polarity transformation in WSe2 transistors enabled by a removable semimetal layer, providing a potential doping-free route toward complementary 2D electronics.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"8 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374624","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}

However, hydrogen permeation remains a critical challenges for pipelines, storage vessels, and other hydrogen-related equipment. These issues not only reduce structural reliability but also raise significant safety concerns during long-term service. To mitigate hydrogen permeation, various hydrogen barrier materials, including metals, ceramics, and polymers, have been extensively investigated. Recently, incorporating two-dimensional (2D) materials used as fillers into polymer matrices has emerged as an effective strategy for enhancing hydrogen barrier performance by increasing diffusion tortuosity and suppressing hydrogen transport pathways. As a result, layered silicates (e.g., montmorillonite, MMT), graphene-based materials, MXenes (e.g., Ti3C2Tx), molybdenum disulfide (MoS2), hexagonal boron nitride (h-BN), and layered double hydroxides (LDHs) have attracted increasing attention for advanced hydrogen barrier applications. Despite rapid progress in polymer/2D filler composite barrier materials, which can be implemented as surface coatings, bulk liners, or free-standing films, enhancement of barrier properties through the optimization of nanosheet alignment, interfacial stability, oxidation resistance as well as scalable fabrication and long-term durability remain major challenges. Moreover, a mechanistic understanding of hydrogen transport and the structure–property relationships that determine barrier performance remains also insufficient, limiting their practical employment in hydrogen-energy systems. Therefore, this review systematically summarizes recent advances in polymer/2D filler composite hydrogen barrier materials, with a particular focus on theoretical aspects related to gas permeability in 2D nanocomposites, hydrogen transport mechanisms, structure–property relationships, fabrication strategies, durability, and engineering applications. Finally, current challenges and future perspectives for next-generation multifunctional hydrogen barrier materials are discussed, aiming to provide guidance for the rational design and industrial implementation of advanced hydrogen barrier systems.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"69 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374621","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}
