MXene-based inks have been widely studied and used for screen-printing electronics, while they usually suffer from poor screen-printability and inadequate mechanical properties of the printed coatings. Therefore, we incorporate 2,2,6,6-tetramethylpiperidinooxy oxidized cellulose nanofibers into MXene ink to regulate its rheology and enhance printability on both porous A4 paper and compact polyethylene terephthalate substrates. The introduction of cellulose enables precise control over the rheology and microstructure of the resultant MXene coatings. Critically, the strong interfacial hydrogen bonding and physical entanglement between cellulose and MXene contribute to the substantial enhancements of the mechanical properties and structural stability of the resultant composite coatings, where a remarkable 9.04-fold increase of hardness and a 1.74-fold increase of Young’s modulus are achieved. The interfacial binding strength between the coating and substrate is also well enhanced with the anchoring of cellulose. This work thereby presents a promising strategy for the design and fabrication of flexible screen-printed electronics.\u0000</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":571,"journal":{"name":"Frontiers of Chemical Science and Engineering","volume":"19 11","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145165832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, efficient H<sub>2</sub> separation remains challenging because of the wide pore size distribution within the chain-packed structure of conventional polyimides. Here, we propose a coordination crosslinking engineering strategy, where Pd<sup>2+</sup> is incorporated into an alkynyl-based polyimide containing carboxyl groups to generate coordination cross-linked networks <i>in situ</i>. The formed coordination bonds significantly reduce the interchain <i>d</i>-spacing and restrict the mobility of the polymer chains, thereby enhancing size-sieving ability. Additionally, the presence of Pd<sup>2+</sup> significantly increases the affinity of membrane for H<sub>2</sub>. Based on their synergistic effect, the optimized EBPA-TB-COOH@Pd<sup>2+</sup>-6 membrane (EBPA: 4,4′-(ethyne-1,2-diyl) diphthalic anhydride; EBPA-TB-COOH: alkynyl-based polyimide polymer) exhibits an unprecedented combination of high H<sub>2</sub> permeability (512.5 bar) and excellent H<sub>2</sub>/CO<sub>2</sub> selectivity (30.4), surpassing most polyimide membranes reported to date. Furthermore, the coordination crosslinking networks endow the membranes with high and stable H<sub>2</sub>/CO<sub>2</sub> separation performance under a wide operating pressure range (1 to 6 bar). This coordination crosslinking engineering strategy offers an effective approach for designing next-generation polyimide membranes for hydrogen recovery and purification.\u0000</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":571,"journal":{"name":"Frontiers of Chemical Science and Engineering","volume":"19 11","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145079051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thermodynamic simulations analyzed the behavior of the metal-bearing solutions during hydroxide precipitation to guide process design. The fractional precipitation process was divided into three steps: pH-adjustment (D1), Co and Ni recovery (D2), and Mn recovery (D3). D2 achieved 89.7% Ni and 76.8% Co recovery; alongside Mn and Li were also removed (15% and 25% respectively). D3 showed mainly Mn recovery (68%) along with 18.7% Co and 7.3% Ni. Simultaneous precipitation resulted in over 99.7% recovery of Co, Ni, and Mn, with a small amount of Li (15%) being recovered from the solution. Na removal from the solution was observed across all experiments. X-ray diffraction analysis revealed that the phases formed were distinct from the predictions. Regardless of the presence of NH<sub>4</sub>OH as a chelating agent in solution, a mixed nickel-cobalt-manganese oxide could be obtained after calcination.
