We investigate the electrical stability of ZnFe2O4-BaTiO3 ME CSNPs (ZFO-BTO ME CSNPs) under various external bias voltages. The phase composition of the core-shell nanoparticles was determined through Rietveld refinement of X-ray diffraction data, indicating a tetragonal BaTiO3 shell and cubic ZnFe2O4 core, present in a weight ratio of 63.63:35.20. Transmission electron microscopy (TEM) analysis shows that the core is composed of ZnFe2O4 with a diameter of 30–50 nm, surrounded by a BaTiO3 shell with a diameter ranging from 100 to 400 nm. Piezoresponse force microscopy (PFM) results demonstrate that ZFO-BTO CSNPs exhibit a stable core-shell configuration up to 1 V, beyond which structural disintegration occurs. The instability of ZFO-BTO ME CSNPs is attributed to nonuniform interfacial strain, low ZnFe2O4 core magnetostriction, and a suboptimal core-to-shell thickness ratio. PFM switching studies reveal 90° domain polarization in the BaTiO3 shell. These findings provide valuable insights into the design of novel core-shell nanocomposites with enhanced magnetoelectric coupling and structural stability.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"72 7","pages":"775-786"},"PeriodicalIF":1.6,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144663807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their development demands strategic techniques to resolve the main drawbacks of their active electrodes, which caused structural instability and poor electrochemical performance in the long run. Atomic layer deposition (ALD) is a thin film coating technique boasting its capability for a uniform, precise, and controllable atomic-level deposition of functional materials. Due to these characteristics, several studies harnessed ALD for ZIB fabrication. Understanding the current narrative of ALD in ZIB development is indispensable to realize new perspectives for its progression in the field. Hence, this review provides an overview of the narrative of ALD in energy storage systems such as ZIBs. The discussion revolves around its fundamental principles, current applications, advancements, and the challenges with ALD. This review concludes by underscoring the essential prospects and perspectives for the future application of ALD for ZIB development.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"72 7","pages":"761-767"},"PeriodicalIF":1.6,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144663774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Owing to the spatial confinement provided by the crosslinking network structure in chitosan-based nanogels and the electrostatic interaction between positively charged chitosan nanogels and negatively charged Cu NCs, the fluorescent intensity of the as-prepared CS-Cu NCs was increased by approximately 17-fold compared with that of Cu NCs. The fluorescence quantum yield is increased by more than four times; the as-prepared CS-Cu NCs exhibited a quantum yield of 64.12%. Additionally, CS-Cu NCs exhibited significantly improved stability in aqueous solution, including excellent oxidation resistance, high anti-salt stability, good thermal stability, and enhanced capacity of anti-photobleaching. These properties provide a fundamental guarantee for the application of Cu NCs with AIE property in the biosensor and bioimaging. Upon the addition of the anticancer drug methotrexate (MTX) to CS-Cu NCs, their fluorescent intensity was markedly quenched. Based on the observed fluorescence-quenching phenomenon of CS-Cu NCs induced by MTX, a novel fluorescence quenching nanoprobe was designed for detecting the labeling amount percentage of commercially available methotrexate tablets. The experimental results validated that our proposed nanoprobe exhibits a wider dynamic linear range and excellent accuracy with a low limit of detection (LOD) of 4.16 μM, thereby expanding the potential application of chitosan-based nanogels encapsulating metal nanoclusters presenting AIE property in pharmaceutical quality control.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"72 7","pages":"804-813"},"PeriodicalIF":1.6,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144663758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focused on the preparation of the ZnO-SO3H nano photocatalyst. The structures of the nano photocatalysts were characterized by field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and N2 adsorption–desorption isotherm analyses. In this study, the effects of the catalyst dose, the zero-charge point, solution pH, and the initial PCB 138 concentration were investigated. FESEM, TEM, and XRD results of the ZnO-SO3H nano photocatalyst showed that ZnO in the presence of ClSO3H has changed to a layered and rod structure. Also, the nitrogen adsorption–desorption isotherm has shown that ClSO3H has changed the structure of commercial ZnO. Based on the results of experiments in batch-mode photoreactor, the optimum amount of the ZnO-SO3H nano photocatalyst, solution pH, and initial concentration of PCB 138 was 2.5 g/L, 7.2, and 2 ppm, respectively. The photodegradation efficiency of PCB 138 after 1 h with the ZnO-SO3H nano semiconductor was 78.55, which had a higher efficiency than commercial ZnO.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"72 7","pages":"768-774"},"PeriodicalIF":1.6,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144663747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the modified Becke–Johnson potential approach, the band gaps of these double halide materials exhibit 1.81, 1.06, and 0.46 eV, showcasing semiconductor behavior. These materials have maximum absorbance, strong optical conductivity in the visible range, and low reflectivity, indicating that they could be used in solar cells and semiconductor gadgets. Thermoelectric findings affirm the potential of these materials for high-temperature thermoelectric power generation.
