The film was created on glass substrates using a sol–gel, dip coating, and controlled etching process, resulting in a porous surface with grass-like nanostructures. After 512 s of etching, the film achieved a roughness of 23.63 nm and a refractive index of 1.14 at 550 nm. It demonstrated excellent broadband anti-reflection, with 96.86% average transmittance and 3.07% reflectance across the 350–1500 nm spectrum, peaking at 99.30% transmittance at 480 nm. The film maintained over 90% transmittance at angles up to 45°, providing omnidirectional functionality crucial for solar panels. Its superhydrophobicity (162.3°water contact angle and hysteresis 7.5°) ensures self-cleaning. When applied as a solar cell cover glass coating, the film enhanced short-circuit current density and power conversion efficiency.

The unique long-chain benzene ring structure in aramid fiber molecules ensures high performance but also reduces surface roughness and chemical reactivity, hindering the formation of stable interfacial structures with polymers like epoxy. This study proposes using an electric field-assisted method to construct the aramid nanofiber (ANFs) self-assembly structure on the aramid fiber surface, increasing roughness and chemical reactivity, thereby enhancing the interfacial bonding strength and insulation properties of AFEP. Testing revealed that the ANFs self-assembly structure was successfully formed on the aramid fiber surface, leading to improvements in both the electrical and mechanical properties of AFEP. The performance of AFEP material was optimal when the electric field-assisted treatment was carried out for 3 min. The flashover voltage was increased by 36.75 %, and the breakdown field strength was increased by 69.08 %. The tensile strength and shear strength were increased by 17.79 % and 30.92 %, respectively. Through molecular simulation, the results show that the addition of ANFs can enhance the interface bonding strength of the model by about 35.5 %. The diffusion coefficient of the epoxy resin was reduced by 68.1 %, indicating that the interface properties of the modified composite were greatly improved.

The findings indicated that coexistence with GO improved the adsorption capacity of OTC or Cu2+ in both single and co-adsorption systems. In the single system, GO incorporation augmented the π-π interaction of the OTC aromatic ring with the soil C=O groups and the hydrogen bonding of the OTC hydroxyl group with the Si-O groups; conversely, for Cu2+, GO intensified the electrostatic attraction of Cu2+ to the soil –OH and Si-O groups. In the OTC + Cu2+ system, Cu2+ facilitated OTC adsorption via a “bridging effect,” while GO incorporation augmented hydrogen bonding between OTC and soil –OH and complexation with Al/Fe-O, while Cu2+ inhibited the hydrogen bonding between OTC and soil Si-O. For Cu2+, the incorporation of GO intensified complexation between Cu2+ and soil C=O and electrostatic interactions with –OH during the co-adsorption of OTC and Cu2+.

The activity tests revealed that Pt nanoparticles with a particle size of 5–15 nm exhibited higher activity for toluene oxidation and maintained good hydrothermal stability on the SBA-15 support. The results suggest that despite the increase of Pt particle size by using DMF, the proportion of Pt0 and the oxygen activation ability were both increased. The reaction pathway of the toluene oxidation over Pt/SBA-15 was examined in depth by in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), proton transfer reaction time-of-flight mass spectrometry (PTR-TOF-MS) and cluster analysis, revealing that the benzyl alcohol, benzaldehyde, and benzoic acid species were primary intermediate products. The benzaldehyde on the larger Pt nanoparticles is conducive to decomposing and generating CO2 for complete mineralization, promoting the activity of toluene oxidation. This work highlights the significance of DMF-induced size effects in the development of low-temperature oxidation catalysts and understanding of reaction mechanism, guiding the design of new efficient toluene oxidation catalysts.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"130 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872388","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 research reports the reliability enhancement of Ge2Sb2Te5 (GST225)-based PCM device with prolonged post annealing time. The results indicate that although the on-current slightly decreases with increasing post annealing time, the voltage required to transform to the SET state remains approximately 1 V. Additionally, the endurance cycle count increases by a factor of 10 for each duration. Furthermore, compared to the device without post annealing, the RESET drift coefficient decreases by 5.3 %, 8.8 %, and 11.4 % for post annealing durations of 3 h, 9 h, and 18 h, respectively, while the SET drift coefficient decreases by 38.9 %, 51.1 %, and 59.6 %, respectively. The changes in electrical properties with increasing annealing time can be explained by analyzing the characteristics of the phase-change material, which provides insights into the impact of subsequent thermal treatment on the crystallization behavior of PCM. These findings are expected to serve as an additional approach to enhance the reliability of phase-change memory, a next-generation memory device, and to influence the understanding of the behavior of constituent elements in the development of new types of semiconductor devices based on chalcogenide materials used in phase-change memory.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"32 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872384","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, we demonstrate the preparation of a highly reactive gold nanofilm (GNF) with a face-centered cubic structure via thermal deposition, followed by atmospheric nitrogen plasma treatment. X-ray photoelectron spectroscopy (XPS) revealed that plasma treatment increased surface hydroxyl and carbonyl groups, introducing nitrogen as metal-nitride and C-NH2 species. Raman spectroscopy further confirmed the incorporation of nitrogen and oxygen functionalities, with intense peaks at 790 cm−1 and 946 cm−1, indicating successful surface activation. The electrochemical behavior of the plasma-treated GNF was evaluated using the [FeIII/II(CN)6]3−/4− redox system through cyclic voltammetry. Notably, the plasma-treated GNF exhibited a substantial increase in anodic and cathodic peak current densities, with the electrochemically active surface area increasing by approximately 276 % and 400 %, respectively, compared to untreated GNF. This enhancement in redox reactivity underscores the potential of plasma-treated GNFs in boosting surface-assisted redox processes.

In this study, SERS substrates were fabricated by sequentially depositing Ag and molybdenum trioxide (MoO3) layers onto hexagonally close-packed polystyrene (PS) spheres via radiofrequency magnetron sputtering in an argon plasma atmosphere. The SERS performance of the fabricated MoO3/Ag/PS films was evaluated by using 4-mercaptobenzoic acid (4-MBA) as a probe molecule. Notably, the SERS intensity of 4-MBA on the MoO3/Ag/PS substrate remained largely unchanged compared with that on the Ag/PS substrate, despite the increased adsorption distance between the adsorbed molecules and Ag particles, regardless of the excitation light irradiation. These substrates demonstrated high sensitivity and uniformity, achieving a detection limit of 9.5 × 10-9 M with a relative standard deviation of 5.25 %. Furthermore, the addition of a MoO3 layer significantly enhanced the storage stability of the substrates by effectively decreasing oxidation of the Ag surface. As a result, the MoO3/Ag/PS films, combining long-term stability with uncompromised detection sensitivity, exhibit excellent potential for high-sensitivity chemical and biological sensing applications. This study introduces a novel experimental approach and lays the foundation for further advancements in SERS substrate research and development.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"22 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872383","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}
