In this study, an on–off-on photoelectrochemical (PEC) aptasensor with dual-signal amplification was constructed based on a covalent organic frame (COF) film to detect β-lactoglobulin (BLG) and Ara h1. Specifically, a uniform and stable TFTA COF film was in situ grown as a PEC signifier on the surface of an indium tin oxide (ITO) electrode. BLG recognition triggered enzyme-assisted circular signal amplification to introduce non-conductive SiO₂-modified DNA (S0) to the platform, effectively quenching the PEC signal for ultra-sensitive detection of BLG. Upon adding Ara h1, SiO₂-DNA was released from the sensing platform to restore the PEC signal, and hemin was added to form a G-quadruplex/hemin compound for secondary signal amplification. Thus, sensitive detections of BLG and Ara h1 were achieved with low detection limits (18 ng/mL for BLG and 2.6 ng/mL for Ara h1) and wide linear ranges (0.05–5 µg/mL for BLG and 0.01–0.2 µg/mL for Ara h1). The dual-amplification and dual-target-responsive PEC aptasensor provides a new idea to develop PEC analysis methods for multi-targets in food and environmental monitoring.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"53 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877875","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}

However, PIM-based solid adsorbents encountered limitation in practical applications due to their singular micropore structure and inadequate mechanical properties. Therefore, there is an urgent need to develop PIM-based porous solid adsorbents with flexibility, durability and excellent adsorption ability. Here, the aerogel-structured nanofibrous molecular sieves composed of amidoxime modified polymers of intrinsic microporosity (AO-PIM-1), have been successfully fabricated by electrospinning via non-solvent-induced phase separation. The obtained AO-PIM-1 nanofibrous molecular sieves were crosslinked through <em>in situ</em> spraying with an epoxy-based monomer to improve their structural stability. How different polymer molecular weight influences the pore structure, porosity and specific surface area of the nanofibrous molecular sieves has been further investigated. Interestingly, this successful construction introduced a hierarchical porous structure in a series of AO-PIM-1 nanofibrous molecular sieves prepared with different molecular weight. This structure serves as a continuous channel for transporting CO₂ molecules, thus facilitating the adsorption capacity. In addition to exhibiting the most uniform porous structure, the AO-PIM-1-A1 nanofibrous molecular sieve (with a weight-average molecular weight near to 47 kDa) exhibited an enhanced mechanical property (2.2 MPa), high specific surface area (445 m²/g) and excellent CO₂ adsorption performance (15.02 % improvement over its powder form). This work will inspire the design and development of high performance porous fibrous adsorbents, not only for the CO₂ adsorption but also for other adsorption applications.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"3 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877853","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}

To ensure system safety, it is crucial to strengthen weak points while maintaining core functions. In this context, we introduce the concept of redundancy design into flexible material systems, using thermoresponsive ionogel systems as a proof of concept. Covalent organic frameworks (COFs) or other porous materials, such as SBA-15 and halloysite nanotubes (HNTs), are incorporated into upper critical solution temperature (UCST)-type PNIPAm-based ionogels through nanoconfined polymerization. This integration yields ionogels with significantly improved mechanical properties: fracture energy is elevated by 170 times at room temperature and 18.2 times at elevated temperatures; toughness is improved by 17 times and 17.5 times; fracture strain is increased by 5.8 times and 1.9 times and stress is enhanced by 1.9 times and 6.2 times, all while maintaining their essential thermoresponsive characteristics. Additionally, these materials exhibit superior shape retention, self-healing capabilities, and strong adhesion to various substrates, underscoring their potential for diverse applications. These results implicated redundancy design can enhance the adaptability of flexible intelligent material systems through molecular-scale design, offering key insights for their extensive application scenarios.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"3 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143876198","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}

However, conventional SPAN electrodes are limited by an active material loading below 40 % and sluggish reaction kinetics. To address these challenges, a Co-N₃S₁ single-atom catalyst (SAC) with a hollow cubic morphology was designed and synthesized, followed by its integration into SeSPAN nanofibers. By employing a dual-mode loading strategy that integrates covalent bonding with physical confinement, the active material loading is increased upto 63 wt%. The three-dimensionally interconnected fiber network provides abundant reactive interfaces, enhancing the accessibility and utilization of Co active sites. Meanwhile, the carbon shell encapsulating the Co-N₃S₁ SAC improves overall conductivity, thereby accelerating lithium-ion and electron transport. Experimental results and density functional theory calculations collectively validate the superior performance of the Co-N₃S₁/SeSPAN cathode, primarily attributed to sulfur incorporation. The high electronegativity of sulfur induces electronic redistribution around Co single atoms, thereby modulating their asymmetric coordination environment, strengthening metal-polysulfide interactions, and effectively lowering the reaction energy barrier. The synergistic optimization of physical and electronic structures not only promotes the solid-to-solid transition from S₈ to Li₂S but also accelerates interfacial reaction kinetics, ultimately enhancing active material utilization and overall battery performance. As a result, the electrode achieves a capacity of 706.7 mAh/g at 0.2 C, retains 545.8 mAh/g at 1 C, and maintains 99.24 % capacity retention over 1000 cycles.

First, to increase the supply of the precursor L-lysine, ARTP mutagenesis was applied to generate a lysine-overproducing mutant strain. Moreover, various gene integration sites were characterized to facilitate the chromosomal integration of the glutarate biosynthetic pathway in this mutant strain. Subsequently, a glutarate biosensor was developed to optimize the rate-limiting DavTD module in the glutarate synthetic pathway through copy number optimization.

Herein, a durable multifunctional photothermal superhydrophobic coating was designed by the pre-self-assembly and in-situ copolymerization of pyrrole (Py) and dopamine (DA). Benefitting from the in-situ growth of Py and DA on the pre-embedded oxidant matrix (FeCl₃), the porous interwoven PPy-PDA nanofiber structure rapidly formed. After encapsulation of highly transparent polydimethylsiloxane (PDMS), the open pores and channels facilitated a remarkable 99 % light absorption by enabling multiple reflections and stable multi-scale structure. Thus, the prepared coating showed efficient photothermal conversion performance with surface equilibrium temperature 93.8 ℃ (1 kW/m²) and superhydrophobicity. In addition, the freezing time of the coating was 22.2 times that of uncoated surface passive anti-icing. Furthermore, the freezing ice could melt within 2 min and rolled off immediately under 1 kW/m² sunlight. Therefore, the prepared coating showed excellent passive anti-icing and photothermal active de-icing property. Importantly, the coating could also be used for photothermal evaporation. Under 1 sun intensity, the solar vapor evaporation rate of the coating was 2.06 kg m⁻²h⁻¹. More importantly, the coating maintained outstanding mechanical and chemical durability, which confirmed by strict tests (sandpaper abrasion test, kneading test, tape-peeling test, high temperature resistance test, strong UV radiation test and different pH solutions erosion test). The outstanding environmental adaptability has a great promise for practical applications of photothermal conversion materials.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"219 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143876277","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}
