Silver nanoparticles (AgNPs) have recently gained significant attention for their strong antibacterial properties. However, their use as standalone antimicrobial agents is constrained by challenges such as AgNPs aggregation, which diminishes activity, and the uncontrolled release of Ag+, which poses toxicity risks. Porous crystalline framework materials (PCFMs) offer an effective solution to these challenges due to their high porosity, large specific surface area, and facile functionalization. Serving as ideal carriers, they enable controlled antimicrobial release, thereby prolonging antibacterial activity. Furthermore, leveraging the intrinsic antibacterial properties of metal–organic frameworks (MOFs) and covalent organic frameworks (COFs) can generate synergistic effects, further improving antimicrobial efficacy. This review examines recent advancements in silver-loaded porous crystalline framework materials (Ag-PCFMs), with an emphasis on Ag-zeolites (Ag-Zs), silver-loaded metal–organic frameworks (Ag-MOFs), and silver-loaded covalent organic frameworks (Ag-COFs), which exhibit synergistic antibacterial properties. First, conventional and emerging synthesis methods are reviewed, followed by an in-depth analysis of how PCFM structural characteristics synergistically enhance the antibacterial activity of AgNPs in composite systems. Finally, the applications of Ag-PCFMs in food preservation, medicine, and environmental purification are assessed, highlighting their potential and outlining future research directions.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"89 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, a sprayable bioadhesive hemostasis powder (GQT) was developed, which could adapt to non-compressible wounds for rapid hemostasis and wound healing. The GQT powder utilized catechol-rich tannic acid (TA) as a cross-linking agent to break the intermolecular hydrogen bonding of gelatin (Gel) and quaternized chitosan (QCS) chains, allowing the powder to exhibit high liquid absorption ability when in contact with blood. Furthermore, the GQT powder promoted the adhesion and aggregation of platelets while regulated coagulation pathways to achieve rapid hemostasis. The GQT powder also possessed antibacterial and immunomodulatory properties.

Currently, challenges remain in enhancing the long-term stability and performance required for practical use. This study reports the in-situ formation of an optimized organic–inorganic hybrid solid-electrolyte interphase (SEI) layer facilitated by the use of a Zn2+/K+ dual-ion electrolyte system, which effectively stabilizes the electrode–electrolyte interface. The SEI consists of an organic-rich outer layer and an inorganic-rich inner layer, composed of ZnCO3, Zn3(PO4)2, ZnF2, and ZnS. Such hybrid organic–inorganic configuration plays a crucial role in facilitating zinc ion transfer and deposition, as well as enhancing the reversibility of the electrodes. Enhanced cyclic stability and exceptional electrochromic performance of the PB||Zn EESD are achieved via SEI, including high optical modulation (ΔT = 69.98 %), rapid switching dynamics (tc = 13.8 s, tb = 12.8 s), excellent coloration efficiency (131.48 cm2 C−1) and outstanding long-term stability (90.8 % retention of optical modulation after 6000 cycles). Essentially, the integrated dual function reflects the efficient energy management strategy since users typically utilize the EESDs to advance solar thermo-optic modulation performance in smart windows while the zero power consumption integrating photovoltaic solar cells is more dominant. This work provides a promising and sustainable solution for applications requiring long-term stability and energy efficiency.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"20 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite extensive studies on the physio-electrochemical characteristics of these solid electrolytes, it is essential to evaluate their stability against organic solvents and binders for successful large-scale commercialization. In this study, we optimized the large-scale synthesis of SnCl2 doped Li7P2S8I (LTPSIC) solid electrolyte using a high energy ball milling process. The LTPSIC solid electrolyte, treated with various polar and non-polar organic solvents and polymeric binders, demonstrated ionic conductivity comparable to that of the untreated LTPSIC solid electrolyte. Moreover, the treated LTPSIC solid electrolytes-maintained stability with a lithium metal anode and showed a critical current density nearly identical to that of the untreated LTPSIC solid electrolyte. Finally, we assembled an all-solid-state lithium battery (ASSB) using the treated LTPSIC solid electrolyte sheet and studied its galvanostatic charge–discharge characteristics. The resulting ASSB displayed an initial specific capacity of 153.3 mAh g−1 with a coulombic efficiency of 72.3 % at a 0.1C-rate. The present work enables the large-scale fabrication of LTPSIC solid electrolytes with high ionic conductivity and stability against organic solvents and polymeric binders.

In the system, SCFAs-consuming bacteria were reduced and SCFAs-producing fermentative genera, such as Paraclostridium, Terrisporobacter and Mobilitalea, were enriched. Additionally, the presence of Fe promoted the enrichment of the Clostridium genus, which is capable of both fermentation and Fe reduction. PF pretreatment enhanced the release of organic matter, thereby shortening the fermentation time. P recovery was effectively achieved through chemical acidification and precipitation techniques. Under optimal recovery conditions (Fe/P = 1.5, pH = 7, 300 rpm), the P recovery efficiency reached 81.6 %, with vivianite accounting for 68.2 %–71.8 %.

Notably, by utilizing red mud, a hazardous industrial byproduct, as a sustainable precursor for perovskite oxides, this study developed Ni-based catalysts using a novel sol–gel combustion method, further enhancing the eco-friendliness and cost-effectiveness. To prepare the catalysts, Al(OH)3 was first extracted from red mud and subsequently used, along with various metals (Ce, La, and Y), to synthesize perovskite oxides. These perovskite oxides were wash-coated onto a monolith reactor, after which 10 % Ni was introduced to form the Ni/MAlO3 (M = Ce, La, and Y) catalysts. With a feedstock-to-catalyst ratio of 10/1 at 800 °C, the Ni/MAlO3 catalysts demonstrated a considerably higher gas yield and H2 generation compared with that of conventional Ni/Al2O3. In particular, Ni/YAlO3 achieved the highest gas yield (56.0 wt%) and H2 selectivity (62.2 vol%) because of the combined influence of well-dispersed metallic Ni active sites and redox properties of Y cations within the perovskite oxide structure, which enhanced tar cracking, water–gas shift, and both steam and dry reforming reactions. Notably, coke formation was effectively suppressed over the Ni/MAlO3 catalysts (<0.54 wt%). Reducing the catalyst-to-feedstock ratio slightly decreased the gas yield and H2 selectivity, whereas increasing the reaction temperature enhanced both gas yield and H2 selectivity, reaching maximum values of 56. 1 wt% and 66.3 vol%, respectively, at 850 °C.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"58 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A comprehensive investigation has been conducted to delve into the underlying mechanisms governing the temperature dependence of a triboelectric nanogenerator. The study centers on a meticulously fabricated triboelectric nanogenerator using a polyimide (PI) nanofiber membrane and encompasses a broad temperature spectrum, analyzing behavior at both room temperature and elevated temperatures. The developed PI nanofiber membrane functions as a versatile platform for converting mechanical energy into electrical with potential to harvest energy even from ultra-low frequency movements like the human pulse or the act of scratching. Additionally, the material boasts a sophisticated triboelectric response strategy. This means it exhibits its peak performance within a specific temperature range, optimizing energy conversion efficiency under these conditions. Open circuit voltage (VOC) reaches 11.76 V at 160 °C, an 84.4 % improvement compared to room temperature. A Kelvin probe force microscopy (KPFM) and fast Fourier transform (FFT) analyses have been performed for the first time to decouple the energy conversion mechanism, confirming its primary dependence on triboelectricity. A comprehensive theoretical study explores the working mechanisms of contact electrification (CE) and the triboelectric effect (TE) during temperature elevation in these nanogenerators (TENGs). This work highlights the potential of PI nanofibers as high-performance, flexible nanogenerators, particularly for applications requiring operation in smart, high-temperature environments.
