This study systematically elucidates water vapor transport mechanisms between air and physical adsorption materials in thermochemical reactors, with emphasis on transient humidity transfer phenomena during incomplete charging and discharging cycles. Moisture saturation was defined as the key parameter for standardized humidity analysis. Results indicate that uncontrolled saturation arises from thermally driven vapor depression, in which water vapor desorbed from materials or transported by inlet air undergoes progressive condensation during downstream migration. Moisture saturation dynamics were governed by coupled effects of inlet air temperature, flow velocity, and relative humidity. Reverse charging was shown to effectively reduce maximum moisture saturation in cases where materials remained incompletely hydrated after prior discharging. Optimization of inlet air conditions through controlled transitions from low-temperature, high-velocity states to a predesigned charging protocol achieved a 45.7% reduction in maximum moisture saturation (from 1.38 to 0.75). In addition, preheating prior to discharging significantly suppressed reactor moisture saturation, thereby mitigating material failure risks.\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":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145315950","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}

Its applications to solid–liquid and liquid–liquid equilibrium calculations are highlighted, particularly in the construction of phase diagrams and the prediction of phase separation phenomena such as amorphous-amorphous and liquid–liquid phase separation. The utility of perturbed-chain statistical associating fluid theory in amorphous solid dispersions is illustrated through its roles in solubility prediction, stability assessment, drug release mechanism analysis, and rational formulation and process design. In addition, perturbed-chain statistical associating fluid theory is critically compared with alternative predictive methods, including solubility parameter theory, Flory–Huggins models, molecular simulation approaches, and machine learning.

In this work, we present a simple surface reconstruction method by adding citric acid to Na<sub>2</sub>SO<sub>4</sub> electrolyte. Citric acid’s multidentate structure strongly chelates the metal-sites on the BiVO<sub>4</sub> surface, triggering lattice reconstruction through intense interactions. This surface modification not only prolongs hole lifetime but also acts as an interface modifier, leaving a carboxyl-rich, superhydrophilic interface on the BiVO<sub>4</sub> surface after the reaction (contact angle ≈ 0°). The multi-dimensional optimization synergistically improves BiVO<sub>4</sub>’s photoelectrochemical performance, achieving an excellent photocurrent density of 6.8 mA·cm<sup>−2</sup> under AM 1.5G irradiation.

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).
