However, the scarcity of ion transport channels and the inefficient lithium-ion migration of SPEs have limited the growth of SPEs in practical applications. Herein, metal–organic frameworks (MOFs) structured nanoparticles (MOF-NP) were incorporated with PEO-based SPEs to obtain the composite polymer electrolytes (CPEs). Specifically, the MOF-NP are composed of MIL-101(Cr) covalently linked polymeric poly(ethylene glycol) diglycidyl ether (PEGDE) chains via the amino group. The amino groups in the MOF-NP formed the hydrogen bonds with PEO chains that reduce the crystallinity of the polymer matrix. In combination with the spontaneous spatial network created from the PEGDE chains, an additional continuous transport channel for Li+ was provided. Therefore, the prepared CPEs (CPEs-MNP) show a high Li+ transport capacity. It is confirmed that CPEs-MNP possesses 4 times higher ionic conductivity (1.2 × 10-3 S·cm−1 at 60 °C) and a much higher Li+ transfer number of 0.66. Furthermore, the assembled cell of Li|CPEs-MNP|Li cycling stable for 1200 h at 0.1 mA·cm−2 and 60 °C with a small initial polarization voltage of 30.7 mV. Meanwhile, the LiFePO4|CPEs-MNP|Li cell exhibits outstanding cycling stability and the discharge capacity reaches 133.2 mAh·g−1 at 2C and 60 °C. It is believed that the as-developed CPEs have a greater vitality in the practical application of high-performance ASSLMBs.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"1 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867058","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}

Utilizing Prussian Blue Analogs (PBAs) for adsorption is an effective strategy for cesium removal, yet there is a paucity of research on PBAs-based ionic liquid for enhancing cesium adsorption performance. In this study, a Prussian Blue Analog-based ionic liquid (IPBA) constructed from tetradecyl trimethyl ammonium (TTAB) was introduced and synthesized for the adsorption of cesium. Batch adsorption experiments indicate that the IPBA consistently achieves over 95 % cesium removal across a broad pH spectrum (pH = 2–12), exhibiting excellent stability. The coordination adsorption mechanism of IPBA is confirmed through the use of XPS, FT-IR, and XRD analyses. The incorporation of hydrophobic long chains significantly enhances the selectivity of IPBA for alkali metals, such as potassium (K+) and sodium (Na+), with a cesium removal efficiency of 98.02 % even in the presence of competing ions at certain concentrations. Column adsorption experiments reveal that IPBA can efficiently remove cesium (99.24 %) within 12 h, even at a higher flow rate of 0.56 mL·s−1. This research offers insights into the design and synthesis of PBAs-based ionic liquid and highlights the potential of ionic liquid in customizing the properties of PBAs for targeted environmental remediation applications.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"25 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867059","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, achieving high-performance TENG active layers that are flexible, stable, durable, and adhere well to the substrate while maintaining room-temperature printing conditions remains a significant challenge. This study overcomes these challenges by using Plasma Jet Printing technology to fabricate advanced fabric electrodes for F-TENGs. We achieved high-quality F-TENG electrode layers by precisely depositing silver nanoparticle (AgNP) layers onto fabrics without requiring post-processing. This process based on Plasma Jet Printing employs a high electric field to eject AgNPs and plasma onto the fabric substrate, resulting in exceptional adhesion and precision, which are critical for enhancing the performance and durability of the electrodes, which surpasses that of traditional Ag-plated electrodes. The printed electrodes achieved a peak instantaneous voltage of 92 V and a current of 9.2 μA—both representing a twofold increase compared to their Ag-plated counterparts. Additionally, these electrodes exhibited an impressive power density of 2166 mW/m2. Furthermore, the study demonstrates the successful integration of the AgNPs-EcoFlex layer into an IoT-enabled adaptive touch and movement sensor system. This integration enables real-time processing, classification, and wireless transmission of touch and motion data, showcasing the potential of F-TENGs in advanced sensing applications. This study underscores the potential of Plasma Jet Printing as a transformative technology for fabricating high-performance, flexible, and durable electrodes for F-TENGs, offering a promising approach for efficient energy harvesting and sensing across a broad range of applications.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"53 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867082","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}

Mn-Ce/ZSM-5 catalyst displayed the best performance for DMF oxidation, achieving 100% DMF conversion and CO2 selectivity at 240 °C as well as 90% N2 selectivity at 400 °C. It also exhibits excellent water resistance and high stability. All the characterization results indicated that the state of Mn species was positively correlated with catalytic activity. The addition of Ce species weakened the inhibitory interaction between Mn species and Al species, resulting in an elevation in the state of Mn species which was highest of the six catalysts, thus increasing activity.

However, CCDP membranes composed of fluorite-perovskite composite materials are rarely studied. The present work employed a composite of Ce0.85Nd0.15O2-δ (NDC) fluorite (75 wt%) and Sm0.6Sr0.4Al0.3Fe0.7O3-δ (SSAF) perovskite (25 wt%) as the ceramic phases to synthesize the novel hollow fiber porous support for CCDP membrane formation. The incorporation of SSAF perovskite functions not only as the partial ion-conducting phase but also as the sintering aid to improve the ceramic densification during the high temperature treatment. The mechanical strength of the resultant NDC-SSAF-carbonate membrane has been greatly improved by 100% but sacrifice CO2 permeation flux by 5% (in case of gas mixture without O2) compared to the fragile NDC-carbonate hollow fiber membrane. The SSAF addition enhanced the electronic conductivity of the membrane, thereby offering the membrane extra function for oxygen transport. Our further comparative studies indicate that the presence of O2 in the feed stream actually can promote the CO2 permeation. In general, the incorporation of perovskite and fluorite in the conducting ceramic phase greatly enhances the mechanical strength of the resultant hollow fiber CCDP membranes and is also favorable for the permeation flux of CO2 in the carpooled manner from the feed to the sweep side when O2 is present in the gas mixture. In regards to the selectivity of CO2 to other gases, the presence of O2 in the feed stream has very minimal effect due to the unique ion transport mechanism.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"111 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867086","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}

Herein, the comparison of the electrochemical performance of polycrystalline LiNi0.9Co0.05Mn0.05O2 (NCM90-P, nano-sized primary particle) and single-crystal LiNi0.9Co0.05Mn0.05O2 (NCM90-S, micro-sized primary particle) high-nickel cathodes reveals that the capacity decay for NCM90-S can be tracked back to structural damage of the particles. Furthermore, in-situ XRD and TOF-SIMS uncover that the root cause of structural degradation is the uneven distribution of lithium ions inside and outside the particles, and it is observed that small particle size and slow rate of delithiation can alleviate this concern.

Aluminum anode (993 mAh/g) with a large volume change of ∼ 97 % is investigated as a proof of concept. Super electrolyte-wettability approaching a contact angle of ∼ 0° is attained via the successful grafting of the polar C-F groups. Meanwhile, owing to the interlayer sliding of dispersed graphitic nanodomains, remarkable strain energy dissipation capacity enhancement is achieved for the ODFC layer. ODFC modified Al anode endows dual-ion batteries (DIBs) with significantly improved cycling stability by 950 %, surpassing DIBs using a pristine Al anode. The ODFC design was further demonstrated in pouch cell DIBs even paired with a high mass-loading graphite cathode (10 mg cm−2).
