The micropillar array was fabricated using UV laser etching, a simplified and efficient alternative to conventional lithographic techniques, significantly reducing processing time and complexity. To enhance the effective dielectric constant variation under applied pressure, we incorporated a gallium-based liquid metal (EGaIn), which features a low melting point (Tm = 15.5 °C), high electrical conductivity (3.4 × 106 S/m), and low toxicity. The sensitivity and pressure range of the sensor were systematically analyzed as a function of EGaIn content and micropillar aspect ratio (AR). The optimized sensor, with 15 vol % EGaIn and an AR of 1, demonstrated a high sensitivity of 2.07 kPa–1 in the low-pressure regime (<135 Pa).

Recently, various reactive oxygen species-mediated strategies have been developed for disinfecting drug-resistant microorganisms. However, development of low-cost cholesterol consumption-based enzyme-mimicking platforms with high antibacterial efficacy remains a significant challenge. Herein, we report the synthesis of a laminated Au-TiO2/C nanozyme, which shows excellent peroxidase-like activity in antibacterial applications. The resultant Au-TiO2/C nanozyme can effectively convert H2O2 into •OH, demonstrating efficient bactericidal activity against Escherichia coli and Staphylococcus aureus. Moreover, based on the prominent peroxidase-like activity of Au-TiO2/C and the cascade reaction of cholesterol oxidase, a sensitive and selective cholesterol colorimetric biosensor was developed. The biosensor exhibits high sensing performance toward cholesterol detection, with a linear detection range from 25 to 300 μM and a detection limit of 13.22 μM. It can also rapidly and accurately detect cholesterol in real serum samples. These findings highlight the dual functionality of the Au-TiO2/C nanozyme as both an effective bactericide and a cholesterol sensor. Hence, the study could contribute great potential to the fast detection and sterilization of multilayer Au-TiO2/C nanozymes in the biomedical field.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"32 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144218914","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 textiles exhibit significant limitations in preserving thermoregulatory microenvironments during dynamic climatic variations. Herein, we present a dual-mode textile (DMT) that combines radiative cooling and solar thermal harvesting technology to achieve year-round passive thermal regulation. The DMT cooling layer demonstrates an impressive performance with 96.1% solar reflectance and 92.0% mid-infrared emissivity. Under direct sunlight, it achieves an average temperature drop of 6.37 °C, corresponding to an average cooling power of 53.3 W/m2. In heating mode, its high solar absorptivity of 90% results in an average temperature increase of 16.3 °C compared to that of ambient temperature. Additionally, the DMT demonstrated excellent mechanical properties and water vapor permeability. Real-world wear tests of the DMT shows a 2.3 °C temperature reduction compared to that of a plain white cotton T-shirt, along with excellent heating performance. Furthermore, simulations indicate that the DMT could cool by ∼5 °C in the summer and insulate by ∼13 °C in the winter compared to conventional clothing. On the whole, this work enables dynamic thermal management across varying conditions, introducing possibilities in the rational design of next-generation smart textiles.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"39 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144218951","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}

The substrate, which is a critical component for antennas, has a great impact on the antenna’s electromagnetic performance and mechanical properties, particularly at millimeter-wave frequencies. However, conventional methods of incorporating low-loss ceramics into stretchable polymers cannot achieve an equilibrium between low dielectric loss and optimal stretchability. To resolve this issue, we present a novel approach that synergistically integrates electrospun barium titanate (BaTiO3) nanofibers with poly(dimethylsiloxane) (PDMS), achieving a composite membrane substrate with ultralow dielectric loss and exceptional stretchability. Based on this advanced substrate, we develop a wearable array antenna that demonstrates stretchability and remarkable radiation characteristics, effectively addressing the constraints associated with conventional PDMS-based antennas.

As a representative case, 2D transition metal dichalcogenides (TMDCs) are usually grown by a chemical vapor deposition (CVD) method based on a van der Waals (vdW) epitaxy mechanism. Commonly used silicon or Al2O3 (sapphire) substrates have either nanoscale roughness or step bunches, and the grown TMDC domains usually show diverse shapes, random orientation alignments with the substrates, and uncontrollable crystalline quality. These problems call for ideal substrates for the vdW epitaxial growth of 2D semiconductors. In this work, we employed graphene monolayers transferred on sapphire wafer as the substrate to investigate the vdW epitaxy of monolayer MoSe2 using a MOCVD technique. We found that the graphene is essentially the substrate, as it shields the influence of the underlying sapphire. Compared with bare sapphire substrates, the MoSe2 domains grown on graphene not only show an equilateral triangular shape and mirror symmetry with respect to the graphene lattice in a wide range of parameter windows, but also the domain size, nucleation density, and growth rate can be well controlled by the processing temperatures, pressures, and precursor flows. These results suggest that graphene film is a proper substrate for vdW epitaxy of 2D semiconductors. We further quantitatively investigated the interfacial forces between MoSe2 domains and graphene using scanning probe microscopy to reveal the weak vdW interaction. Our work highlights the importance of substrates for the vdW epitaxial growth of 2D semiconductors and paves the way for substrate optimization in the 2D film growth and device integrations.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"6 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144211667","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}

The pronounced anisotropy of low-dimensional perovskite optimized carrier migration pathways and effectively suppressed cross-talk between proton and photoinduced carriers in the transverse direction, thereby enabling efficient detection and memory.

However, achieving high-quality perovskite detectors remains challenging due to bias-induced ion migration. The primary concern is the lack of recovery strategies to promptly heal migrated ions during operation, realizing high device stability and exceptional optoelectronic performance. Herein, we proposed a proactive healing strategy of migrated ions by alternating current voltage (ACV) to achieve a low current drift and high optoelectronic sensitivity. Under the ACV, bulk ion migration can be effectively controlled to maintain the long-term stability of perovskite devices. The as-grown defects would annihilate during the ACV post-treatment, decreasing defect density and improving crystal quality. Therefore, more stable and balanced hole and electron photoresponses are harvested after the ACV post-treatment. The treated MAPbBr3 detector exhibits a low dark current drift (∼10–6 nA cm–1 V–1 s–1) and excellent sensitivity [5.43 × 104 (hole) and 4.78 × 104 (electron) μC Gyair–1 cm–2].

The lateral dual-gate CNT FET device leverages the inherent randomness of the CNT network formed during the deposition process, allowing for the generation of unique, unclonable encryption keys. By using dual independent gates, this device achieves a quaternary state implementation, enhancing security within the same device footprint compared with traditional binary bit PUFs. The randomness of the CNT network, combined with the dual-gate operation, allows for the extraction of different threshold voltage (VT) from a single transistor, which are then used to classify four distinct states, further improving security. PUF performance indicators, such as the interchip Hamming distance and uniformity, were evaluated, and both indicators were found to be close to the ideal value of 50%.
