Conventional PSDs, typically based on the lateral photovoltaic effect of silicon or other semiconductor junctions, are prone to radiation damage and material degradation, limiting their reliability under harsh conditions. Silicon carbide (SiC), with its wide bandgap, high mobility, low defect density, and strong resistance to radiation damage, offers a promising alternative for developing robust detectors. In this work, we present a PSD based on undoped 4H-SiC, designed with a simple vertical structure that eliminates the need for complex multi-interface architectures. The device demonstrates excellent performance, including a light on–off ratio exceeding 10<sup>3</sup> under sub-milliwatt illumination, spatial resolution of ∼0.1 μm, and fast response times of ∼10 μs (rise) and ∼6.3 μs (fall). It also exhibits remarkable stability under γ-ray irradiation (300 krad) with minimal photocurrent variation, making it suitable for accurate position tracking in radiation-prone environments. This work highlights the potential of 4H-SiC-based PSDs for advanced sensing applications that demand both high performance and resilience in extreme environments.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"40 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495911","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, the efficacy of current treatments is hampered by challenges in delivering antibiotics to recalcitrant oral biofilms and bacterial resistance, thereby impeding successful treatment of infectious diseases. To address the issues, an antibacterial photothermal material was designed, comprising a spherical structure of zinc oxide (ZnO) wrapped with triiron tetraoxide (Fe<sub>3</sub>O<sub>4</sub>). The outer layer of the material adsorbed epsilon-polylysine (EPL) by electrostatic action, ultimately leading to the fabrication of Fe<sub>3</sub>O<sub>4</sub>/ZnO/EPL nanoparticles (FZE NPs). The Fe<sub>3</sub>O<sub>4</sub> core endowed the nanoparticles with efficient photothermal properties, facilitating the dispersion of dense biofilms, which dramatically promoted the adsorption and penetration of ZnO and EPL into the biofilms to effectively kill bacteria in biofilms <i>in vitro</i> with enhanced sterilization ability. Additionally, upon dissolution in aqueous media, EPL acts as a positively charged antimicrobial peptide that adsorbs onto the surface of negatively charged bacterial membranes, thereby effectively modulating inflammatory responses. In order to ascertain the efficacy of FZE NPs, an investigation was conducted into their antimicrobial effects against the periodontitis-associated pathogen <i>Porphyromonas gingivalis</i> (<i>P. gingivalis</i>) <i>in vitro</i>. Furthermore, the antiperiodontitis potential of FZE NPs was evaluated in Sprague–Dawley (SD) rats of ligamentous periodontitis. In addition, toxicity evaluations indicated that the material had an acceptable biosafety profile <i>in vitro</i> and <i>in vivo</i>. In summary, the nanospheres (FZE NPs) represent a promising therapeutic strategy for the treatment of periodontitis.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"15 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495906","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 this study, a piezoelectric-ultrasonic bimodal electronic skin (PUVE) based on <i>in situ</i> polarized PVDF–TrFE/2DBP composites and a thin-film transistor (TFT) array is fabricated. The incorporation of 2DBP into the PVDF–TrFE film and the <i>in situ</i> polarization approach provide excellent piezoelectric and ultrasonic performances of PVDF–TrFE/2DBP composites. PUVE has an ultrahigh sensitivity of 3.2 mV kPa<sup>–1</sup> over a wide pressure (0–310 kPa) range, with excellent spatial resolution (50 μm) and response time (40 ms). Meanwhile, the PUVE demonstrated outstanding repeatability and bending stability in 1500 cycles of cyclic pressure and 4000 cycles of 180° bending. The integrated piezoelectric and ultrasonic functions of PUVE can respond individually to dynamic and static tactile stimuli to ensure perceiving and decoupling of the dynamical and static mechanical signals with one single sensor. The PVDF–TrFE/2DBP composites is further integrated with the TFT array, realizing visualization function of contacting objects and restoring their characteristic information including the texture and location.

These polymer nanoparticles were fabricated using a biocompatible poly(lactic acid) (PLA) matrix by an effective microemulsion-based method.

In this study, we showcase the deposition of transition metal phthalocyanine (TMPc) molecules onto a self-supporting conductive carbon cloth electrode using an environmentally friendly sublimation technique for efficient electrocatalytic CO<sub>2</sub> reduction. We meticulously investigated the preparation conditions, including the heating temperature and TMPc type, to assess their impact on the CO<sub>2</sub> reduction activity.

With a sufficiently high Sn composition, GeSn is classified as a direct bandgap semiconductor. Polycrystalline GeSn holds several additional advantages, including its significantly lower synthesis cost compared to its epitaxial counterpart, as well as the versatility to grow these films on a variety of substrates. Here, we present a polycrystalline thin-film GeSn phototransistor on a fused silica substrate with a Sn composition of ∼10%, showing a photoresponse in the short-wave infrared wavelength range, critical for emerging sensing applications. This device shows a gate-tunable response, with responsivities approaching up to 1.7 mA/W with only a 30 nm-thick GeSn layer. Furthermore, phototransistors offer additional adaptability through gating, which allows for the reduction of dark current. This not only enhances the signal-to-noise ratio but also offers more flexible integration with various image sensor readout implementations using different substrates. The specific detectivity of this phototransistor is within an order of magnitude of those of previously reported GeSn photodetectors grown by molecular beam epitaxy and chemical vapor deposition, even though the absorber is 3 to 20× thinner while the electrode spacing for photocarrier transport is approximately 15× longer than the carrier diffusion length in this work, showing great potential benefits of extending similar device structures to epitaxial GeSn layers. As these GeSn phototransistors utilize a noncrystalline substrate, our work establishes a fundamentally more versatile path toward monolithically integrated GeSn-based photodetectors for next-generation multimodal sensors.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"18 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495735","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}
