This strategy can also be employed to induce high deformability in organic electronics. In this review, studies on the regiochemistry of conjugated polymers based on the dimensions of regiochemical factors and synthesis methods are summarized to enable the control of the regiochemistry of substituents, side chains, and backbone linkages that can impact their optoelectronic properties and solid-state morphologies. Moreover, technological developments in the fabrication of OFETs with highly enhanced mobility toward stretchable electronics have been discussed.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"19 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701350","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 study examines the electrical transport properties of a single-layer MoS2 field-effect transistor on a few-layered hBN substrate. Temperature-dependent transport measurements reveal that electrical conductivity is predominantly governed by a combination of simple activated and variable-range hopping mechanisms. The calculations on the experimental data yield a localization length around 5 nm for a typical defect density near the Fermi energy as 1014 eVcm-2. Additionally, optoelectronic transport measurements exhibit temperature-dependent persistent photoconductivity, attributed to electron localization within defect states. Calculations based on the temperature-dependent photoconductivity relaxation indicate a localization length of 7 nm, suggesting a direct correlation between the two phenomena.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"42 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701351","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}

In contrast, this work demonstrates the use of two-photon polymerization to induce superhydrophobicity on hydrophilic substrates solely through structural design. A comprehensive set of Salvinia-inspired microstructures was fabricated with precise control over geometrical features such as the number of arms, arm diameter, fill configuration, spacing, and height. Static contact angle measurements revealed that surface architecture plays a pivotal role in modulating wettability, with optimized structures achieving contact angles above 160° without any chemical modification. The study further investigates how morphological fidelity, governed by two-photon polymerization (TPP) printing parameters─specifically slicing distance and hatching distance─influences surface quality, roughness, and droplet behavior. Power spectral density analysis and 3D surface topography confirm that fabrication resolution critically impacts the performance of designed features. Finally, fabrication efficiency was evaluated in terms of areal fabrication rate, highlighting trade-offs among design complexity, printing resolution, and throughput. The results establish a set of design principles for achieving superhydrophobicity on hydrophilic materials and provide a scalable framework for future applications in microfluidics, biomimetics, and surface engineering where chemical-free wettability control is desired.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"12 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701150","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}

Recently, the rapid development of machine learning methods has caused a major revolution in the field of catalytic chemistry, which promises to accelerate the catalyst development with unprecedented efficiency. This review systematically introduces the fundamental concepts and workflows of ML in catalysis, followed by a comprehensive overview of both traditional machine learning─typically based on small data sets and shallow models─and deep learning (DL), which leverages large-scale data and complex architectures. We highlight key modeling strategies, algorithmic frameworks, and representative applications in catalyst design, reaction prediction, and surface adsorption systems.

Indeed, the structural diversity afforded (e.g., Zr-node density, pore size, and ligand stability) enables a high degree of control over the chemistry and structure of Zirconium MOF (Zr-MOF)-based or MOF-derived catalysts (MDCs). Here, we synthesize ternary CO2 hydrogenation catalysts from MOF-based precatalysts and examine the effect that the MOF structural features have on the CO2 hydrogenation catalyst structure and activity. This was achieved by preparing Cu/ZnO@Zr-MOF precatalysts with microporous (UiO-66) and mesoporous (MIP-206 and NU-1000) templates. It was found that the Cu/ZnO@Zr-MOF precatalysts underwent in situ structural transitions under reaction conditions that were temperature dependent. Microporous UiO-66 converts to small domains of ZrO2, with Cu dispersion (surface vs interior) dictated by the rate of support conversion at 200, 225, and 250 °C (Cu/ZnO@ZrO2). The mesoporous MOFs (MIP-206 and NU-1000) templated Cu nanoparticles with ZnO clusters on a ZrO2 support (Cu/ZnO@ZrO2) under mild reaction conditions (200/225 °C, 40 bar, 3:1/4:1 H2/CO2), but at higher temperatures, the less stable MIP-206 support converted to small crystalline domains of ZrO2 as well as templating Cu nanoparticles. Indeed, these MDCs displayed varied catalytic activity and selectivity, depending on the MOF template and formation temperature, most notably MIP-206- and UiO-66-based catalysts showing improved activity for methanol formation when prepared at higher temperatures (250 °C, 40 bar, 3:1 H2/CO2; but tested under milder conditions), whereas the NU-1000-derived catalysts gave reduced activity due to pore blockage and poor access to catalyst sites. Our results indicate that higher-performing catalysts can be accessed through careful selection of precursor Zr-MOF with appropriate structure metrics and judicious choice of in situ activation conditions.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"25 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144693534","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, reported water permeability values vary widely, suggesting the presence of additional, unrecognized factors influencing water transport. In this study, we demonstrate that both the dynamic microstructure of MXene membranes under pressure and the flake size of Ti3C2Tx, used in fabrication play critical roles in determining water flux. We observed a substantial decline in water permeability, from tens of L/m2·bar·h to below 5 L/m2·bar·h, during filtration, attributed to compaction of the initially loose membrane structure. Notably, the change in the microstructure is reversible, with the disordered microstructure recovering after drying. Moreover, MXene flake size is found to impact the tortuosity of water pathways, where membranes constructed from smaller flakes exhibit higher permeability. For example, membranes fabricated with an average flake size of 4 μm achieved water permeabilities 2.15 times lower than those made with 0.17 μm flakes. These findings underscore the complex interplay between microstructure dynamics, flake size, and liquid transport, offering key insights for the rational design of high-performance MXene-based separation membranes.","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":"144701012","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 flexible sensors often suffer from limitations, such as low sensitivity and inadequate resistance to mechanical and chemical degradation. To address these issues, this study presents a CPU@MXene@SiO2 superhydrophobic flexible sensor fabricated using a combination of electrospinning and dip-coating techniques. This sensor features a sandwich structure composed of an electrospinning fiber membrane (CPU) substrate, an MXene conductive coating, and a superhydrophobic SiO2 coating. Based on the fabricated sensor, strain and piezoresistive sensors were further assembled to systematically investigate the effects of micro/nanostructures and chemical compositions on wettability and sensing performance. Experimental results demonstrated that the CPU@MXene@SiO2 sensor exhibited outstanding comprehensive properties including high mechanical strength, superhydrophobicity (CA > 155°, RA < 3°), low adhesion force (33 μN) with water, high sensing sensitivity (gauge factor up to 4922.6), and fast response (response time of 94 ms). Moreover, to validate its potential for large-scale applications, a complete data acquisition system based on an STM32 microcontroller and a mobile application was designed and developed. A 4 × 4 sensor array was successfully fabricated and tested. This sensor demonstrates promising and attractive applications in wearable devices and human-machine interaction, offering an efficient design strategy for constructing robust and highly sensitive flexible sensors.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"37 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144693536","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}

Antibodies play a crucial role in epidermal injury repair by precisely regulating inflammatory pathways and neutralizing key inflammatory factors. Notably, conventional IgG antibodies face limitations including poor stability, immunogenicity, and reduced efficacy in epidermal environments. Therefore, developing an alternative antibody delivery system capable of overcoming these limitations has become a critical issue to address. Egg yolk antibody (IgY), with its unique Fc structure, exhibits excellent thermal stability and biosafety, making it ideal for treating skin and mucosal diseases. Here, this study proposes an innovative topical IgY hydrogel sustained-release system (IgY-Gel) to deliver TNFα-specific IgY (anti-TNFα IgY), which is demonstrated to effectively reduce the levels of inflammatory factors like IL-6 in LPS-stimulated RAW264.7 cells. The system synergizes with thermosensitive chitosan/β-glycerophosphate (CS/β-GP) hydrogels exhibiting controlled-release properties to enhance the proliferation and migration of human umbilical vein endothelial cells (HUVECs) under pro-inflammatory conditions. In addition, this system demonstrates accelerated wound healing in a mouse wound model, with a significantly higher healing rate of 95.7% in the anti-TNFα IgY-Gel group after 14 days, compared to the respective rates of 73.7%, 77.6%, and 81.7% in control, blank-Gel, and ns IgY-Gel groups, respectively. In conclusion, our IgY-Gel system highlights the anti-inflammatory and wound-healing potential of topical IgY therapy. This innovative system promotes the translational application of antibody therapies toward engineered biologics with enhanced efficacy and safety profiles in tissue repair processes.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"19 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701011","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 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}
