The dispersions were formulated by combining cellulose nanocrystals (CNC) and hydrophobically modified ethylhydroxyethylcellulose with beeswax nanoemulsions. The beeswax nanoemulsion was prepared using the Ouzo effect, a low-energy, surfactant-free, and spontaneous emulsification method. EHM serves as an anchor for CNC and beeswax nanoparticles on the canvas, forming a continuous film and preventing aggregation during the treatment process. Tensile tests and contact angle measurements demonstrated that the dispersions effectively strengthen the canvas and enhance its water resistance, addressing the moisture-induced mechanical limitations observed with previous nanocellulose and polyelectrolyte consolidants. Additionally, the hydrophobicity of the beeswax-CNC/EHM system can be adjusted by varying the beeswax content. Overall, the use of entirely green components and the straightforward preparation process make this dispersion system highly adaptable for consolidation in cultural heritage conservation, particularly in scenarios where a hydrophobic surface is required.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202500058"},"PeriodicalIF":3.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144075203","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}

But so far, the photoluminescence quantum yield (PLQY) of most these solids is still relatively low and the persistent room temperature phosphorescence (p-RTP) emission is relatively weak. To improve their PLQY and p-RTP, pressing the powder into tablets has been preliminarily proven to be an effective method, but the specific mechanism has not been fully elucidated yet. Here, carboxymethyl β-cyclodextrin (CM-β-CD) has been chosen as the representative to solve the problem. The results showed that the PLQY and p-RTP lifetimes of the tablet of CM-β-CD were improved compared to the powder. By the mechanism of clustering-triggered emission (CTE) and average packing density-promoted emission (PDE) mechanism, it has been demonstrated that the enhanced molecular interactions after compression is the key reason, which resulting in the formation of cluster emission centers with stronger emission capabilities. CM-β-CD has been proven to have excellent cell imaging and anti-counterfeiting functions.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202500230"},"PeriodicalIF":3.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143963571","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}

Crystalline porous materials have emerged as promising candidates for iodine adsorption due to their high surface areas, tunable porosity, and abundant active sites. This review comprehensively summarizes recent advancements in the design and application of four classes of crystalline porous materials for iodine capture: metal-organic frameworks, covalent organic frameworks, hydrogen-bonded organic frameworks, and porous organic cages. The discussion focuses on key adsorption mechanisms, structural modifications, and functionalization strategies that enhance iodine adsorption capacity, retention, and recyclability. While significant progress has been made, challenges remain in scaling up synthesis, improving stability under industrial conditions, and achieving cost-effective large-scale applications. Future research should emphasize on scalable synthesis, industrial validation, and development of multifunctional adsorbents with enhanced selectivity and reusability. This review provides insights into the rational design of next-generation porous materials for efficient iodine capture, contributing to advancements in nuclear waste management and environmental sustainability.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e2500087"},"PeriodicalIF":3.0,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143951644","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}

In this, molecular oxygen has been used as an ideal and green oxidant which activates the inert C-N bond. We prepared various derivatives of aryldiazonium tetrafluoroborate salts which includes different electron withdrawing and electron donating group substituents. This protocol utilizes Pd/C as a heterogeneous catalyst which is smoothly recyclable. Moreover, this developed method is ligand and co-catalyst free and it does not require any base to activate the amines as nucleophile, and the new process effectively provides a mild pathway toward a variety of tertiary amide moieties with significant yield. This way, the potent protocol is economical, simple, recyclable and operates at milder conditions and contributes towards valuable products that are vital in an industrial domain.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202500153"},"PeriodicalIF":3.0,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143960609","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}

At present, the degradation of lead-based materials due to ion migration phenomenon and the long-term instability of the prepared devices are still important problems that hinder their practical application. In this study, we incorporated KI into the BA2MA3Pb4I13 polycrystalline detector fabricated via the lamination method. The introduction of KI enhanced both the crystallization quality and charge carrier transport capability of the perovskite polycrystalline film. By introducing K+ ions into the interstitial site of perovskite, the effective channel for ion migration was reduced, leading to increased ion activation energy, and then the ion migration in perovskite was effectively inhibited. Consequently, the prepared X-ray detector exhibits improved stability, with a sensitivity of 6250 μC Gyair-1 cm-2 and a detection limit of 19.7 nGyair s-1. This study broadens the idea of enhancing the stability of perovskite and lays a research foundation for its practical application.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202500066"},"PeriodicalIF":3.0,"publicationDate":"2025-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143956786","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}

In this study, we present a simplified approach by mechanical blending of BaSr2CoTiSbO9 (BSCTS), an OER catalyst, with BaSr2MnTiSbO9 (BSMTS), an ORR catalyst, to construct a composite bifunctional electrocatalyst. The DFT calculation supports superior ORR activity of BSMTS due to an uplifted Mn d-band center than the Co d-band and its proximity to the Fermi level, whereas the greater OER activity of BSCTS is due to the uplifted O 2p band center. While microstructural similarity of BSCTS and BSMTS facilitates efficient mixing for composite formation, the mechanical blending avoids intervention of complex synthesis procedures. The resulting bifunctional composite electrocatalyst demonstrates excellent performance with a bifunctional index of 0.72 V and a peak power density of 125 mW/cm2 when used as an air cathode electrocatalyst in Zn-air battery (ZAB). This approach underscores the importance of mechanical blending of microstructurally compatible OER and ORR catalysts in designing practical bifunctional electrocatalysts for zinc-air batteries.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202500171"},"PeriodicalIF":3.0,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143958013","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}
