Grazing-incidence wide-angle X-ray scattering of 5,5′-bis(naphth-2-yl)-2,2′-bithiophene (NaT2) on octadecyl-trichlorosilane-passivated Si, graphene, MoS2, muscovite mica, and in operando thin-film transistors reveals substrate-dependent unit cells, polymorphs, strain fields, and epitaxial orientations. Bulk crystallography exposes multiple polymorphs in ambient conditions and under compression up to the gigapascal regime. In situ vacuum deposition experiments track layer-by-layer nucleation, a wetting-layer–mediated 2D-to-3D transition, and the emergence of bulk packing. High stability permits long measurements, whereas strong crystallinity enables high quality diffraction signals even from monolayers and through diamond-anvil cells and high-background vacuum chambers. Detailed comparisons with other small-molecular-weight thiophenes are made throughout to contextualize and generalize these observations. Together these results establish naphthyl-terminated thiophenes as convenient model systems for probing substrate interactions, growth modes, and strain-coupled polymorphism in organic semiconductors.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 19","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500458","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145248607","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}

While their functional roles are well understood, the mechanical properties driving these differences require further investigation. Using atomic force microscopy (AFM), this work measures mechanical properties of both pads on the same tarsus under near-physiological conditions at different indentation depths and velocities. The results reveal that the arolium exhibits a lower effective elastic modulus (EEM) and higher work of adhesion (WOA), suggesting its efficacy in generating adhesion forces. Conversely, the euplantulae demonstrates a higher EEM and lower WOA, supporting their role as friction pads. Furthermore, it is demonstrated that altering the velocity and indentation depth has a significant impact on the mechanical properties of both pads revealing their viscoelastic characteristics. This study provides the first comparative analysis of the mechanical properties of both types of attachment pads on the same tarsus in living stick insects, validating the complementary roles of the arolium and euplantulae. These results contribute to better understanding of structure–function relationships in insect attachment devices and might be of interest for biomimetic engineering of adaptive adhesives and soft robotics.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 19","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500616","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145248575","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}

Though most often used to image work-function variations of conductive surfaces, it can also be used to probe the surface charge on insulating surfaces. In both cases, relating the measured potential to the underlying signal is non-trivial. Here, general relationships are derived between the measured SKPM voltage and the underlying source, revealing either can be cast as a convolution with an appropriately scaled point spread function (PSF). For charge that exists on a thin insulating layer above a conductor, the PSF has the same shape as what would occur from a work-function variation alone, differing by a simple scaling factor. This relationship is confirmed by: (1) backing it out from finite-element simulations of work-function and charge signals, and (2) experimentally comparing the measured PSF from a small work-function target to that from a small charge spot. This scaling factor is further validated by comparing SKPM charge measurements with Faraday cup measurements for highly charged samples from contact-charging experiments. These results highlight a heretofore unappreciated connection between SKPM voltage and charge signals, offering a rigorous recipe to extract either from experimental data.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 19","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500521","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145248712","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}

However, their long-term operational instability, especially under thermal, moisture, and illumination stress, remains a major barrier to commercialization. This review summarizes recent advances in interface and electrode engineering strategies aimed at simultaneously improving the stability and efficiency of PSCs. In particular, charge transport layer optimization is emphasized, including the use of dopant-free polymers, bilayer structures, and inorganic materials, as well as interfacial passivation approaches. Furthermore, emerging electrode technologies, such as carbon-based electrodes and hybrid metal–carbon architectures, which address issues of metal ion migration, corrosion, and interfacial degradation, are explored. Interfacial modifiers, molecular passivators, and dimensional control strategies are also reviewed for their role in enhancing charge extraction and suppressing recombination. Through a comprehensive discussion of these materials and device-level innovations, insight is provided into scalable pathways for fabricating stable and high-performance PSCs suitable for real-world applications.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 19","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500297","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145248704","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}
