Here, we employ first-principles calculations to investigate the evolution of band edges in monolayer MoS<sub>2</sub>, boron phosphide (BP), and MoS<sub>2</sub>/BP heterostructures before and after their rolling into nanotubes. Our research results indicate that the intrinsic MoS<sub>2</sub>/BP vertical heterostructures exhibit a type-II direct bandgap, but this feature is not robust under strain. For MoS<sub>2</sub>/BP coaxial heterotubes, the type of bandgap is influenced by both chirality and diameter. Specifically, when the diameter exceeds 19 Å under zigzag chirality, the system undergoes a transition from a type-I direct bandgap to a type-II direct bandgap, which remains stable within a strain range of −6 to 6%. Furthermore, we delve into the alterations in band edge positions in single-walled nanotubes induced by curvature-driven flexoelectric effects and circumferential tensile strain. In coaxial heterotubes, the transfer of electrons between the inner and outer tubes forms a cylindrical capacitor-like structure. Incorporating the inherent flexoelectric voltage in single-walled nanotubes, we have derived a functional relationship between the counteracting voltage (<i>V</i><sub>hyb</sub>) and their diameter. Finally, the system was explored for its strong light absorption capabilities with absorption levels up to 10<sup>5</sup>, and it was found that strain can effectively modulate the range of light absorption. The findings of this research contribute to new insights and theoretical foundations for the development of novel one-dimensional (1D) van der Waals (vdW) optoelectronic devices.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"10 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142849759","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}

For excellent outdoor durability, however, the traditional strategy of using UV absorbers inevitably weakens the cooling performance of polymer-based coolers. The introduction of a high UV-reflective layer has been proven to be the most effective strategy to eliminate the negative effects of UV absorption and improve the durability of polymer coolers. Here, a polymer multilayer film (PMF) based on an optical interference mechanism is designed, which exhibits an average reflectance of up to 92.3% in the 300-400 nm UV wavebands. Using a TiO<sub>2</sub>-doped epoxy resin (TiO<sub>2</sub>-EP) cooler as an example, the solar reflectance of TiO<sub>2</sub>-EP increases by 5.43% after introducing PMF as a UV reflective layer. Outdoor tests without shading or convection coverage demonstrate that the average cooling temperature of TiO<sub>2</sub>-EP with PMF is further elevated by approximately 1.1 °C. Additionally, its aging rate decreases significantly, and the solar reflectance is 5.08% higher than that of TiO<sub>2</sub>-EP without PMF after 120 h of UV aging experiments. Furthermore, PMF obtains a periodic multilayer structure by multilayer coextrusion, which has the advantages of low cost and the ability to be prepared over a large area.

This study utilizes solution-processed zinc–tin oxide (ZTO) thin-film phototransistors and modulates the values of <i>V</i><sub>G</sub>, which allows for the regulation of electron trapping/detrapping at the ZTO/SiO<sub>2</sub> interface. By coupling the excited photonic carrier and electronic trapping, logic gates such as “AND,” “OR,” “NAND,” and “NOR” can be achieved. With the exponential growth in data generation, efficient processing and storage solutions are imperative. However, extensive data transfer between computing units and storage limits the level of artificial neural networks (ANNs). Consequently, quantized neural networks (QNNs) have gained interest for their reduced computational resource requirements and lower consumption. In this context, we introduce an optimized ternary logic circuit based on ZTO devices. By utilizing optical modulation to adjust the turn-on voltage of the single device, we demonstrate the achievement of ternary current states, thereby providing three distinct discrete states. This configuration can be extended to QNN computing, demonstrating multilevel quantized current values for in-memory computation. We achieved a handwriting digit recognition rate of 91.6%, thereby demonstrating reliable QNN hardware performance. This robust QNN performance indicates that the metal oxide phototransistor shows significant potential for future ternary computing systems.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"82 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142849822","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}

Currently, EFCs face challenges of poor stability and catalytic efficiency at the cathodes, necessitating solutions to enhance the oriented immobilization of multicopper oxidases for improved heterogeneous electron transfer efficiency. This study successfully identified a surface-binding peptide (SBP, 13 amino acids) derived from a methionine-rich fragment (MetRich, 53 amino acids) in <i>E. coli</i> CueO through semirational design. The first phase of engineering focused on the structural characteristics of MetRich, pinpointing fragment N394-H406 (SBP 1.0, corresponding to variant CueO-M12) as the key region dominating the binding. Subsequent site-saturation mutagenesis, combined with electrochemical screening, yielded three variants, and among them, the variant CueO-M12-1 (CueO-M12 H398I) exhibited a more uniform favorable orientation with a 1.38-fold increase in current density. Further electrocatalytic kinetics analysis revealed a significant 21.2-fold improvement in kinetics current density (<i>J</i><sub><i>k</i></sub>) compared with that of CueO-WT, leading to the development of SBP 2.0. When SBPs were fused to laccase from <i>Bacillus pumilus</i> (<i>Bp</i>L) and fungal bilirubin oxidase from <i>Myrothecium verrucaria</i> (<i>Mv</i>BOD), respectively, they transformed a sluggish adsorption process into a rapid and oriented one. In addition, compared with SBP 1.0, SBP 2.0 endows <i>Bp</i>L and <i>Mv</i>BOD with enhanced electrocatalytic capabilities for oxygen reduction and glucose/O<sub>2</sub> EFC performance. The engineered SBPs are promising for serving as a versatile “glue” to enable the immobilization of oxidoreductases in an oriented manner, which leads to a breakthrough in bioelectrocatalysis and thereby overcoming the current bottleneck of EFCs.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"62 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142849754","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}
