The optimized 5-PCNPC hydrogel exhibits a broad pressure-sensing range (2.3–100 kPa) with a sensitivity of 0.360 mV·kPa⁻¹ (a 34.8 % enhancement) and a rectification ratio of 12.9, enabled by PCDMC-guided anisotropic ion transport and rapid stress dissipation (337 ms recovery). With excellent durability over 500 cycles and a power density of 1.17 mW·m⁻², the hydrogel sensor demonstrates its potential in practical applications, including a 5 × 5 touchpad for spatial pressure mapping and real-time monitoring of respiration, swallowing, grasping and locomotion.

Here, carbon black nanoparticles (CB NPs) coated leather matrix was incorporated with PVA/PAA hydrogel to design and fabricate solar interfacial evaporator. Benefiting from the hierarchical and porous structure of collagen fiber clusters with abundant functional groups, CB NPs and hydrogel precursor can be easily interpenetrated into the leather matrix, generating the multiscale and interlocking networks with enhanced strength (16.20 MPa tensile strength, 7.97 MJ m⁻³ toughness) and interfacial force (0.08 MPa). Besides, this network framework possesses the abundant channels that could facilitate the water transmission. Water evaporation rate of 2.00 kg m^-2h⁻¹, water evaporation efficiency of 128.4 %, as well as stable cycling without salt accumulation can be achieved.

However, triplet excitons are highly susceptible to thermal stimulation, leading to rapid deactivation, which limits the ability of organic afterglow materials to sustain long afterglow emission at high temperatures. In this work, a universal and effective strategy is proposed, wherein aromatic carboxylic acids (AMA) are dissolved in a hot boric acid (BA) solution, followed by drying and melt dehydration processing, successfully synthesizing a series of HTA materials. The BO matrix provides a rigid and thermally stable environment, effectively constraining molecular vibrations and preventing non-radiative transitions of triplet excitons. In this HTA material, both triplet hot exciton afterglow (HEA) and thermally activated delayed fluorescence (TADF) dual-mode emission are realized, along with tunable afterglow colors from blue to green. TCPB@BO demonstrates visible blue afterglow with a duration of 0.5 s and a long lifetime of 175 ms at 543 K. This synthetic strategy not only expands the application of HTA materials in anti-counterfeiting, but also offers protective solutions for temperature monitoring in electric vehicle batteries and chips in servers, with broad application prospects. It provides an innovative approach to preventing the detrimental effects of thermal damage in high-tech devices.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"5 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144165165","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, the electrochemical performance of FZABs is hampered by the lack of gel polymer electrolytes (GPEs) with efficient ion transport and the presence of zinc dendrite growth issues in an alkaline environment. Herein, by incorporating rare earth ions of La³⁺ and Ce³⁺ into the polycationic gel polymer frameworks, a novel cationic CPAM-LC GPE with enhanced ion transport is constructed through the dynamic competitive coupling mechanism to achieve rapid transport of hydroxide ions. The CPAM-LC GPE exhibits prime ionic conductivity (327 mS cm⁻¹), excellent mechanical properties and interfacial adhesion. Moreover, the FZAB with CPAM-LC GPE shows superior performance, achieving a maximum power density of 203.4 mW cm⁻² and over 1300 charge–discharge cycles. Most importantly, the synergistic effect of La³⁺ and Ce³⁺ with polycationic chains in the CPAM-LC GPE can effectively regulate the deposition behavior of Zn(OH)₄²⁻, thereby significantly enhancing the reversibility of the zinc anode. Thus, this strategy using rare earth ions in polycationic GPEs offers a valuable reference for developing high-performance, interfacial stable FZABs in strong alkaline electrolytes.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"35 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144165186","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}

Using metal–organic frameworks (MOFs) as active electrodes for energy storage or conversion is very attractive; however, it is challenging due to their limited robustness in acidic/basic environments. In this study, we present the development of a chemically robust 3D Co-squarate framework (Co-SQ), a metal–organic framework (MOF) with high structural stability across a wide <em>pH</em> range (2 to 12), featuring a Co₄(µ₃-OH)₄ cubane secondary building unit (SBU) similar to MOF-5. This material was synthesized from inexpensive, readily available precursors without requiring calcination or chemical modification for supercapacitive applications. Co-SQ demonstrates decent gravimetric (456F g^–1) and areal (570 mF cm^–2) capacitance at a current density of 1 A g^–1 and 1.25 mA cm^–2, respectively, along with cycling stability over 10,000 cycles and decent energy and power densities. We further explored its application in advanced energy storage systems by fabricating Swagelok-type cells, coin cells, and flexible pouch-like devices (LSC@PI), which powered an LED bulb for several minutes. These results highlight Co-SQ’s superior electrochemical performance, comparable to, or exceeding, that of other MOF-based and commercial supercapacitors.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"9 2 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144165200","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}

More importantly, Ru/TiON-C outperforms the Pt/C benchmark both intrinsically (2.5 times higher turnover frequency) and in terms of metal utilization (4.5 times higher mass activity). The exceptional HER activity of Ru/TiON-C is related to the metal-support interaction (MSI) induced by TiON, which was experimentally evidenced by X-ray photoelectron spectroscopy and further investigated by density functional theory calculations. It can be proposed that MSI enhances water dissociation properties and tunes hydrogen adsorption energy at Ru active sites, while stability is provided by the strong anchoring of the Ru nanoparticles on the TiON.
