However, achieving long-term stability in terms of catalytic performance remains a critical hurdle for large-scale commercial deployment. This mini-review provides a comprehensive exploration of the key factors influencing CO2RR stability, encompassing catalyst design, electrode architecture, electrolyzer optimization, and operational conditions. We examine how catalyst degradation occurs through mechanisms such as valence changes, elemental dissolution, structural reconfiguration, and active site poisoning and propose targeted strategies for improvement, including doping, alloying, and substrate engineering. Additionally, advancements in electrode design, such as structural modifications and membrane enhancements, are highlighted for their role in improving stability. Operational parameters such as temperature, pressure, and electrolyte composition also play crucial roles in extending the lifespan of the reaction. By addressing these diverse factors, this review aims to offer a deeper understanding of the determinants of long-term stability in the CO2RR, laying the groundwork for the development of robust, scalable technologies for efficient carbon dioxide conversion.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202500174"},"PeriodicalIF":3.5,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143810050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 activation of hydrothermally synthesized Cu metal-organic framework (MOF-199) with potassium citrate (C6H5K3O7) to produce MOF-derived carbon incorporated with nano-dispersed metallic Cu and oxidative Cu species to facilitate electrochemical CO2 reduction. Among all MOF samples, the resulting MOF-derived carbon, activated by C6H5K3O7, demonstrated the highest electrocatalytic current and lowest charge transfer resistance, achieving a Faradaic efficiency exceeding 50% for the production of acetic acid (CH3COOH) at an applied potential of - 1.1 V (vs RHE). The addition of C6H5K3O7 during preparation endowed the MOF-derived C with a mesoporous structure, thereby enhancing CO2 adsorption and activation. A proposed reaction pathway suggested that the generation of nano-dispersed metallic Cu is critical for forming Cu─C bonds for producing CH3COOH. This study indicates that Cu-containing MOF-derived carbon with beneficial properties for electrocatalytic applications owing to its nanoispersed Cu features could be readily synthesized.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202401171"},"PeriodicalIF":3.5,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143810342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The integration of MnO2-based colloidal motors with common mouth-rinsing H2O2 solutions for sterilization and disinfection via reactive oxygen species (ROS) represents an ideal approach. In this study, we fabricate uniform dumbbell-shaped (DS-MnO2-motor), spherical (S-MnO2-motor), and silver half-coated spherical Janus Ag-MnO2 colloidal motors (JS-MnO2-motor) using hydrothermal, co-precipitation, and sputtering methods, respectively. These motors are propelled by O2 bubble ejection generated from the catalytic decomposition of low-concentration H2O2 by peroxidase-like MnO2 components. Notably, the JS-MnO2-motors achieve a maximum speed of 146.4 µm s-1 in gargle containing 1.5% H2O2. In vitro and in vivo antimicrobial trials demonstrated that the JS-MnO2-motor gargle exhibits superior sterilization rates of 98.1% and 97.4% against both planktonic and biofilm-forming P. gingivalis and F. nucleatum. Consequently, it significantly enhances the therapeutic efficacy in treating periodontitis in Wistar rats, as evidenced by a marked reduction in inflammatory cells. The mechanical force exerted by these colloidal motors, along with cation adhesion to bacterial membranes and the antimicrobial effects of ROS, collectively contribute to this enhanced performance. Our findings introduce a novel strategy for the treatment of chronic inflammatory diseases.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202500157"},"PeriodicalIF":3.5,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143810023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we report the development of a mechanoresponsive fluorescent polymer with photogated properties, comprising poly(methyl acrylate) (PMA) and the photoswitchable mechanophore S2A2, which features two anthracene groups linked by a disilane spacer. The mechanochromic polymer PMA-S2A2 exhibits ratiometric fluorescence response upon mechanical deformation, which arises from the monomer and excimer emission ratio of anthracene controlled by the polymer strain. The mechanochromic property of the polymer can be switched off by irradiation with 365 nm UV light which induces [4 + 4] cycloaddition of the anthracene groups between and within the polymer chains. Importantly, the anthracene dimers can be reversibly dissociated in situ within the polymer film by irradiation with 254 nm UV, restoring the mechanochromic function. Furthermore, intermolecular photodimerization of anthracene increases the molecular weight and forms an entanglement network, significantly enhancing the material toughness. This reversible photocontrolled switch design offers a novel strategy for developing mechanochromic materials with modulated responses and mechanical properties.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202500317"},"PeriodicalIF":3.5,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143802166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite achieving remarkable progress in cancer treatments, conventional chemotherapeutic drugs face numerous limitations. To this end, nanomaterial-based targeted drug delivery systems have emerged as a hope of promise. In this study, we report the design and development of transferrin (Tf) tethered naphthalene-diimide-based fluorescent organic nanoparticles (NDI-OH-Tf) for targeted delivery of paclitaxel to cancer cells with over expressed transferrin receptors (TfR). Spherical NDI-OH FONPs were fabricated through J-type of aggregation of NDI-OH amphiphiles in a 1:99 (v/v) DMSO-H2O mixture. These NDI-OH FONPs exhibited aggregation induced emission (AIE) at an emission wavelength of λem = 594 nm. The hydroxyl groups on the surface of the NDI-OH FONPs were conjugated with carboxyl groups of transferrin, forming NDI-OH-Tf FONPs. These NDI-OH-Tf FONPs were successfully used for targeted bioimaging and drug delivery to TfR+ cancer cells through ligand receptor interaction between transferrin and TfR. Notably, paclitaxel loaded NDI-OH-Tf exhibited ∼2.9-fold higher efficacy toward TfR+ cancer cells compared to normal cells and ∼3.3-fold higher cytotoxicity than free PTX due to transferrin mediated targeted accumulation of PTX in cancer cells.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202500135"},"PeriodicalIF":3.5,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143802170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
