These inhibitors, categorized into organic and inorganic types, mitigate corrosion through adsorption and reaction mechanisms that form protective layers on metal surfaces. To enhance their performance, carriers such as micro/nanocapsules and porous materials are utilized to enable on-demand, stimuli-responsive release. The criteria for designing carriers for effective corrosion inhibition are also explored. Covalent organic frameworks (COFs) are identified as a revolutionary solution owing to their high porosity, multifunctional properties, and tunable structures. As advanced nanocarriers, COFs play a pivotal role in smart protective coatings, integrating corrosion inhibition with self-healing functionalities.

In this study, we introduced an innovative iron-based single-atom nanozyme (Fe−N/C) sensor array. This sensor array integrates both colorimetric and photothermal dual modes and is aimed at accurately distinguishing various SCMs. Fe−N/C catalyst is capable of facilitating the conversion of 3,3′,5,5′-tetramethylbenzidine (TMB) into oxidized TMB (oxTMB) by activating O2, which can turn the colorimetric signal into a photothermal signal under external infrared laser irradiation, allowing for the quantitative detection of SCMs. By leveraging this dual-mode detection technology, the detection range for SCMs extends from 5 to 150 μM. The limits of detection (LODs) are 0.688–0.887 μM for the colorimetric method and 0.011–8.5 μM for the photothermal method. Different SCMs can suppress oxTMB to varying extents, generating distinct colorimetric and photothermal dual-mode response changes on the sensor array, successfully identifying five types of SCMs. Additionally, it has been utilized for detecting and distinguishing real food samples, including grape wine, pure milk, and raw egg.

Traditionally, achieving high outcoupling efficiency has relied on external optical elements, which increase manufacturing costs. This paper presents a novel approach of sandwiching a silver film between silver oxide and Di(1-naphthyl)-N,N′-diphenyl-(1,1′-biphenyl)-4,4′-diamine (NPB) films on a glass substrate to form a glass/silver oxide/silver/NPB system designed to enhance anti-reflective (AR) properties to improve the performance of green OLEDs. Experimental investigations revealed that incorporating 2 nm thick silver oxide (Ag2O) layer between the glass substrate and silver film results in a notable increase in the light transmittance of the electrode from 18 to 40 %. This enhancement is attributed to the formation of a silver film with conical surface structures, which reduce reflection and improve light coupling. The application of an AR NPB layer on the silver surface further increases the transmittance to ~70 %, demonstrating the effectiveness of the double anti-reflective coating. The devices with the Ag₂O/Ag electrode exhibited significant performance improvements, achieving a maximum luminance of 9573Cd/m2, which is approximately 75.3-fold higher than the plain Ag electrode and current efficiency of the Ag₂O/Ag device reached 4.26 Cd/A.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"11 4","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143883884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
