In this study, an environmentally friendly approach was employed to develop a new adsorbent material, MIL@MgFe-LDH/SA, derived from metal-organic frameworks (MOFs)-based layered double hydroxide (LDH) and fabricated into aerogel beads for phosphate removal from wastewater. By selecting MIL-100(Fe) as a template and utilizing a simple alkaline hydrolysis-assisted coprecipitation method, the excellent morphological characteristics of the MOFs were preserved in the aerogel beads, maintaining the distinct structure of the LDH nanosheets and significantly enhancing their adsorption performance. The aerogel beads, prepared via a crosslinking granulation method, effectively overcome common issues faced by powder adsorbents, such as compression, agglomeration, and difficulty in recovery during the adsorption process. These aerogel beads exhibit an extremely low density, enabling significant swelling in aqueous solution and recovery to a hydrogel state, thereby maintaining good stability and functionality. In a 200 mg P/L phosphate solution, MIL@MgFe-LDH/SA aerogel beads demonstrated an adsorption capacity of 60.26 mg P/g. The adsorption process followed the pseudo-second-order kinetic model and the Freundlich adsorption isotherm. Even in the presence of coexisting anions (e.g., Cl^–, NO₃^–, and CO₃^2–), the sample displayed excellent selectivity for phosphate removal. The microstructure and characteristics of the sample were thoroughly analyzed using scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), Fourier-transform infrared (FT-IR), X-ray photoelectron spectroscopy (XPS), nitrogen adsorption–desorption tests, and Zeta potential measurements. Furthermore, Density functional theory (DFT) calculations and molecular dynamics (MD) simulations were conducted to explore the phosphate adsorption mechanism. The results indicate that phosphate adsorption primarily occurs through electrostatic interactions and surface electron transfer between the LDH surface and phosphate species, demonstrating that MIL@MgFe-LDH/SA aerogel beads possess excellent phosphate removal capacity and can effectively eliminate phosphates from aqueous solutions","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"41 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143539136","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}

The precise immunomodulatory capabilities of microcapsules are attributed to their unique core–shell structure. The cavities of microcapsules allow for efficient loading of drugs, antigens, and other immune substances, while the shells provide additional functions such as protecting the core from harsh external environments, enabling surface modification or further loading of immunopotentiators, and facilitating controlled release. This review summarizes recent advances in the development of immunomodulatory microcapsules, encompassing those with intrinsic immunomodulatory properties and those loaded with immunomodulatory molecules. Subsequently, their applications in the immunotherapy of tumor, inflammatory, and autoimmune diseases are introduced. It highlights diverse strategies regulating both innate and adaptive immune responses, such as macrophage polarization, regulation of inflammatory factors, and T cell activation. Finally, the opportunities and challenges associated with the clinical use of immunoregulatory microcapsules and prospects for their future role in immunotherapy are discussed. This comprehensive overview aims to provide valuable insights and guidance for the design and application of microcapsules in immune modulation, serving as a critical reference for researchers in advancing personalized medicine and targeted therapies.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"12 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143546953","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, we present a non-destructive molecular-microstructural engineering strategy to address the intrinsic limitations of styrene–butadiene–styrene (SBS) triboelectric nanogenerator (TENG). By incorporating 2-nitrobenzoic acid (2-NBA) into a SBS matrix via an electrospinning method, we achieve dual optimization of electron-capture capability and interfacial contact efficiency. The nitro group (–NO₂) in 2-NBA significantly enhances the electron-withdrawing properties of SBS, while its inherent polarity induces self-assembled neuron-like hierarchical microstructures during fiber formation, eliminating the need for post-treatment. The resulting TENG exhibits exceptional performance at an optimal 2-NBA loading of 5 wt%, delivering an open-circuit voltage of 220 V, a short-circuit current of 412nA, and a transferred charge density of 39 nC under 10 N pressure. Notably, the device demonstrates a high sensitivity of 30 V kPa⁻¹, surpassing most reported SBS-based TENG. Crucially, this physical blending approach circumvents the safety hazards and structural degradation associated with conventional chemical modifications (e.g., fluorination) while retaining the intrinsic flexibility of SBS. The simplicity, scalability, and post-treatment-free nature of this strategy highlight its potential for industrial applications in wearable electronics, human–machine interfaces, and IoT-enabled sensing systems.

However, the efficiency of the CO₂ reduction half-reaction is constrained by the structural configuration of the hydrogen bond network of water on the catalyst surface, because it controls the H₂O dissociation half-reaction that was deemed as the rate-determining step in the overall CO₂ reduction reaction. Herein, we propose a novel concept of confining an asymmetric water hydrogen-bond network to enhance H₂O dissociation, thereby providing protons for CO₂ reduction and significantly increasing the rate of HCHO formation. As a demonstration of feasibility, sulfur-doped graphite carbon nitride (g-C₃N₄-S) was successfully prepared as the desired prototype photocatalyst. We unravel that −SO_x species on g-C₃N₄-S photocatalyst enhance the adsorption concentration of CO₂ and *CO intermediate by promoting the adsorption of H₂O. More importantly, −SO_x species boosts the dissociative adsorption of H₂O due to altering the symmetric water hydrogen bonding network on the interface into a confining asymmetric one, thereby accelerating the activation and conversion of CO₂ adsorbed on the catalyst surface. As a result, the production of HCHO over the g-C₃N₄-S (180.9 μmol) has increased 2.5 times compared to the pristine g-C₃N₄ (72.9 μmol). The novel approach of enhancing CO₂ photoreduction efficiency by regulating the water hydrogen-bond network structure at the interface offers a promising avenue for advancing CO₂ conversion efficiency.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"53 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143546951","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}

By optimizing liquid transfer within each functional module, the ASDIE achieves a balance between liquid transport and evaporation rates under varying solar intensities. Experiments were conducted to evaluate the evaporation performance of the ASDIE. The results demonstrate that variations in the SA concentration within the hydrogel effectively regulate the water content on the evaporation surface at different surface temperatures.

Additionally, the ASDIE reduces the average total heat loss to 14 % through its multi-level supply structure and adaptive liquid transport capabilities, corresponding to a 39 % reduction relative to TSDIE.
