This paper successfully modifies the electrical properties of ambipolar silicon junctionless nanowire transistors (Si-JNTs) using the reducing properties of ammonia (NH3) for selective detection. Physisorption of NH3 induces a dual response in both p- and n-type conduction channels of ambipolar Si-JNTs, significantly altering current and key parameters, including the \"on\" current (Ion), threshold voltage (Vth), and mobility (μ). NH3 interaction increases conduction in the n-channel and decreases it in the p-channel, acting as an electron donor and hole trap, as supported by Density Functional Theory (DFT) calculations. This provides a pathway for charge transfer and ″pseudo″ molecular doping in ambipolar Si-JNTs. This NH3-mediated molecular doping and conduction modulation in Si transistor enabled, for the first time, the electrical detection of gaseous NH3 at room temperature across a wide concentration range (200 ppb to 50 ppm), achieving high sensitivity (200 ppb) and precise selectivity under ultraviolet (UV) light. UV illumination dynamically modulates current and reveals distinct sensing features in the p- and n-channels of the dual-responsive Si-JNTs. The ambipolar Si-JNT sensor exhibits a fast response time of 1.91 min for 0.8 ppm of NH3 in the hole conduction channel and a high sensitivity of 80% for 0.8 ppm of NH3 in the electron conduction channel. This dual-channel approach optimizes sensor performance by leveraging the most responsive parameters from each channel. Furthermore, the ambipolarity of Si-JNTs broadens the parameter space for developing a multivariate calibration model, enhancing the selectivity of Si-JNT sensors for NH3 detection.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"20 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701016","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, conventional temperature sensors often require external power, rely on complex instrumentation, and may perturb the thermal field, compromising measurement accuracy in passive sensing scenarios. Although thermochromic materials offer visual and passive temperature feedback, their utility is limited by narrow sensitivity ranges and subjective interpretation. To address these challenges, this study introduces a machine-vision-enabled microarray passive temperature sensor (MAPTS) inspired by the cooperative perception mechanism of insect compound eyes. The system comprises arrays of organic thermochromic materials patterned via soft lithography on flexible, thermally conductive substrates, enabling wide-range passive thermal sensing. A deep learning-based ResNet-34 architecture deciphers the color-to-temperature relationship from optical images, facilitating high-precision, noncontact regression-based temperature prediction. Experimental results demonstrate that the MAPTS achieves dynamic thermal responses across 0-70 °C with a rapid prediction time of 50 ms. In a high-density 7 × 7 array configuration, the system exhibits better extrapolation performance (R2 = 0.9996) and higher prediction accuracy (mean absolute error ≤ ±0.3 °C), compared to conventional thermochromic sensing methods. This work presents a cost-effective, highly accurate, and reliable approach for intelligent temperature monitoring in diverse applications.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"704 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701015","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}

Unlike conventional approaches, this platform leverages an innovative biofunctional nanocomposite of Ti3C2Tx MXene, tetraethylene pentaamine-functionalized reduced graphene oxide (TEPA-rGO), and Nafion, functionalized with anti-IL-6 antibodies, integrated into a carbon-based screen-printed three-electrode chip. The system achieves unprecedented sensitivity in IL-6 quantification, with a single-digit pg/mL detection limit and a broad range of 3-1000 pg/mL using ∼5 μL of serum. The sensor design is uniquely enhanced through the introduction of a genetic algorithm-based thin-layer diffusion model, which optimizes critical, previously unknown electrochemical transport parameters, including diffusion coefficient, rate constant, charge transfer coefficient, and electrochemically active surface area. This approach represents a significant advancement in biosensor modeling and performance tuning. The sensor demonstrates exceptional selectivity (signal-to-noise ratio ∼ 6.9) against relevant interferents (e.g., sepsis-related antigens, small molecules, electroactive compounds), retains operational stability for a month, and offers a sample-to-answer time of ∼15 min (i.e., up to 12 times faster than traditional ELISA), while maintaining comparable sensitivity. Detailed morphological, topographical, and chemical analyses validate the structural and functional integrity of the TEPA-rGO/MXene/Nafion nanocomposite. By combining cutting-edge nanomaterials with advanced computational modeling, this IL-6 sensor sets a new benchmark for rapid, precise cytokine detection, offering transformative potential for early disease diagnosis and prognosis.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"704 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144693532","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, hard carbons derived from the direct carbonization of lignocellulose usually exhibit small pore volumes, which leads to low capacity and poor rate capability. Current studies have provided a limited understanding of the structural evolution mechanism of single-component and intercomponent interactions that determine the closed pore and crystalline structure of hard carbon derived from lignocellulose. Additionally, the correlations between the closed pore structure and the sodium-ion storage capabilities in hard carbons need to be better established. Herein, we have developed an effective process to prepare hard carbons derived from lignocellulose for enhanced sodium-ion storage. Specifically, we demonstrate an effective reconstruction strategy where a high closed-pore volume (0.23 cm3 g-1) and small closed-pore sizes (1.80 nm) were simultaneously achieved, resulting in excellent electrochemical sodium-ion storage performance. The lignocellulose-derived hard carbon thus exhibits high capacities of 350 mA g-1 at 50 mA g-1 and 236 mAh g-1 at 5000 mA g-1. This study provides both mechanistic understanding and practical strategies for modulating the microstructures of a lignocellulose precursor to design high-performance hard carbon anodes.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"123 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701006","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}

This hydrogel integrates natural bioactive components (chitosan, protocatechuic aldehyde, and Fe(III)) and serves as a scaffold for Mn single-atom nanozymes (Mn SAN). Through dynamic covalent and hydrogen bonding, the hydrogel exhibits exceptional adhesion, injectability, degradability, and self-healing capabilities. The embedded Mn SAN, leveraging their unique metal active center, deliver superior catalytic activity and selectivity. When introduced into endometrial lesions in mice, this bioactive hydrogel exerts a synergistic effect that not only significantly boosts cell proliferation but also effectively modulates hormone levels. As a result, it facilitates remarkable tissue repair within a mere two-week period. Importantly, this therapeutic approach is both hormone- and cell-free, representing a noninvasive intervention.

NH3 is synthesized through a conventional Haber-Bosch process; however, this method requires considerable energy. Thus, it is important to develop NH3 synthesis catalysts that operate under mild conditions. This research revealed that Sm-doped Ru/La2Ce2O7 catalysts (Ru/La2Ce2-xSmxO7) increased the NH3 synthesis under mild conditions (400 °C, 0.1 MPa). Catalyst with an optimal Sm doping ratio (x = 0.75) showed the highest NH3 productivity of 4563 μmol h-1 g-1. This result is mainly attributed to the transition from a fluorite to a C-type structure by introducing Sm to Ru/La2Ce2O7, since the C-type structure possesses a higher abundance of oxygen vacancies compared to fluorite. This structural transition facilitated electron transfer to the active Ru metal and enhanced hydrogen spillover on the support, substantially improving the performance of the optimized catalysts. Nevertheless, the introduction of Sm dopants brought certain deactivation effects, including blocking active sites on Ru and promoting a high degree of ordering in the oxygen vacancy, which induced the degradation of electron mobility. As a result, it became evident that not just the concentration but also the arrangement of oxygen vacancies critically influences the catalytic performance. These results underscore the importance of precisely tuning the Sm doping level to achieve a balance between its beneficial and adverse effects on the structural and electronic properties, which is critical for maximizing ammonia synthesis activity.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"28 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144693530","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, current technologies are constrained by fluorinated chemical dependencies, complex manufacturing workflows, and limited substrate adaptability. Herein, we present a fluorochemical-free, eco-friendly, scalable coating system through a one-step spray deposition of antimony selenide (Sb2Se3), stearic acid (STA), and poly(methyl methacrylate) (PMMA). The synergistic incorporation of Sb2Se3 and STA creates a micro/nano structure with enhanced surface roughness (Ra = 189.937 nm) and low surface energy, achieving exceptional liquid repellency (water contact angle: 165°, sliding angle: 3°). The optimized Sb2Se3/STA/PMMA (Sb2Se3-SP) composite demonstrates remarkable substrate versatility, adhering robustly to diverse surfaces (metals, glass, paper, and wood) without requiring pretreatment. Notably, the Sb2Se3-SP coating exhibits a 4.67-fold extension in delayed ice freezing time (280 s at -20 °C) compared to that of uncoated substrate (60 s at -20 °C). Furthermore, the intrinsic photothermal conversion capability of Sb2Se3 enables rapid surface heating, rising to 80.0 °C in 180 s under 1-sun illumination (0.14 W/cm2), facilitating autonomous ice melting without external energy supply. Besides, the Sb2Se3-SP coating exhibits outstanding mechanical durability and self-cleaning property.
