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. This innovative design offers new ideas and methods for efficient detection.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"11 4","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143884103","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}

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}

Efforts have also been directed towards simplifying WLED fabrication through the development of single-component white-emitting phosphors, with certain halide perovskites proving suitable for this purpose. This review specifically focuses on various design approaches and emission mechanisms of white photoluminescent colloidal halide perovskite nanocrystals (CHPN) and their derivatives, irrespective of dimensional and materials types of perovskite. We compare three distinct sources of white light: narrow band edge free excitonic emission, dopant emission, and other broad-band emissions. The review supplements the potential of CHPN as single phosphors for WLEDs, highlighting their role in achieving cost-effective and environment friendly lighting solutions. Recent advancements and associated limitations of WLED fabricated with white-emitting CHPN are thoroughly assessed. Finally, we outline current challenges and propose future research directions aimed at achieving high-quality CHPN with white photoluminescence that meets commercial standards.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"11 4","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143883847","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}

Heat transfer measurements are conducted on Au NP hydrogels using laser-light induced heating, revealing a size- and concentration-dependent temperature increase compared to the plain agarose gel matrix. Experimental data, combined with finite-element analysis, demonstrate that photothermal energy conversion efficiencies are dependent on NP size and concentration, while the thermal conductivity (TC) of all Au NP hydrogels remains constant and independent of these parameters within the tested concentration range. UV-visible spectroscopy indicates that the observed photothermal heating arises from light absorption and scattering within the Au NP hydrogels. This work highlights the interplay between plasmonic Au NPs of varying sizes and hydrogels as host matrices, significantly impacting photothermal energy conversion properties.

To achieve this, water-soluble, fluorescent silver-capped gold nanoparticles (F−AgAu) has been synthesized and characterized through conventional methods. The sensing behaviour of the F−AgAu for several analytes of interest has been investigated by employing steady state and time-resolved spectroscopic techniques. Signaling strategy has been conceptualized by exploiting both “turn-on” and “turn-off” condition of the fluorescent nanoparticles against specific analytes in sequential manner. The method is based on the F−AgAu/Hg2+ system, where the initial fluorescence from F−AgAu is quenched (“turn-off”) by Hg2+. Time-resolved fluorescence studies have revealed that a photoinduced electron transfer (PET) process from nanoparticle to Hg2+ is primarily responsible for the fluorescence quenching behavior. Interestingly, in the presence of GSH, the fluorescence of the nanoparticle is found to be recovered (“on” state). The fluorescence “on” state of the nanoparticles is attributed to the competitive affinity of Hg2+ for thesurface ligand, GSH. More interestingly, it has been demonstrated that the present signaling strategy is quite effective in detecting GSH in various fruits and food samples at low concentration levels.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"11 3","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690243","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}

For the first time, we aimed to evaluate the effects of plasma surface functionalization of HAp nanoparticles (NPs) on the chemical, physical, and bio-functional properties of chitosan films using experimental and computational evaluations. Atmospheric air plasma process was conducted on HAp NPs at two different air pressures (650 and 1300 mTorr) and four different exposure times (1, 3, 6, and 9 min), followed by fabrication of HAp/chitosan bionanocomposites. Fourier transform infrared (FTIR) spectra proved that the position of bands at 1639 and 1037 cm−1 were shifted to 1635 and 1031 cm−1 due to the interaction between chitosan amine groups and HAp phosphate groups. Quantum mechanical and molecular dynamic (MD) simulations were used to understand the interactions between chitosan and HAp. Density functional theory (DFT) calculations were used to explore the electronic properties of untreated and plasma-treated HAp (T-HAp). MD simulations using the PCFF force field were used to investigate the interactions of HAp/chitosan and T-HAp/chitosan bionanocomposites. According to the results from thermal gravimetric analysis (TGA), the duration of HAp NP plasma treatment is a significant factor in the weight loss properties for the resultant HAp/chitosan bionanocomposites. The overall reflectance % properties of films prepared with T-HAp NP samples decreased, confirming the potential applications for skin tissue protection against solar UV radiation. The bioactivity of the bionanocomposite films was also studied by examining the HAp formation by incubating in simulated body fluid.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"11 3","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690242","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}
