{"title":"Grafting of Curcumin onto Caffeic Acid for Biomass Derivative toward Enhanced Photostability and Color Uniformity in Dyed Silk","authors":"Mengqi Tian,Jiahong Zuo,Wanli Liu,Yuyang Zhou","doi":"10.1021/acs.iecr.6c04555","DOIUrl":"https://doi.org/10.1021/acs.iecr.6c04555","url":null,"abstract":"Curcumin (CCM) is a high-performance natural yellow pigment with excellent chromaticity and versatile bioactivities, holding great potential for eco-friendly textile dyeing. Nevertheless, its industrial utilization is severely restricted by inherent photolability and uneven color distribution. Conventional modifications, including metal mordanting, structural derivatization, and synthetic antioxidant blending, improve the UV stability of CCM, but introduce inevitable drawbacks such as chromatic deviation, toxic residues, and competitive dye–fiber binding interference. Herein, a fully biobased, water-dispersible, and UV-resistant CCM derivative (CCMMod) was fabricated via CDI-mediated covalent condensation between CCM and plant-derived caffeic acid (CA) with intrinsic UV-shielding capability. FTIR, UV–vis spectroscopy, and HPLC–MS results confirm successful covalent grafting, whereby CCMMod achieves significantly enhanced hydrophilicity and photoretention capacity compared with pristine CCM. Dye adsorption on silk follows a multistage behavior involving rapid interfacial binding and gradual intrafibrillar diffusion toward equilibrium, and the kinetic process is well fitted by the pseudo-second-order model based on noncovalent interactions between CCMMod and silk protein groups. Relative to neat CCM-dyed silk, CCMMod-treated fabrics exhibit superior washing and rubbing fastness, with the light fastness rating improved from 1.5 to 3.5. After 20 h of standard UV irradiation, CCMMod-dyed silk retains 59.9% of its original K/S value, while pure CCM-dyed silk only maintains 10.8%. Notably, silk dyed with 5% owf CCMMod acquires a UPF value above 40, benefited from the synergistic UV attenuation of curcuminoid and caffeoyl moieties. This eco-friendly CDI-based conjugation strategy effectively overcomes CCM’s intrinsic photolability, providing a scalable and universal platform for renewable dye modification and sustainable low-carbon textile dyeing.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"56 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218833","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}

The standard expression assumes that the partial molar volume of the component in a liquid or solid mixture is identical to the molar volume of the pure component in the liquid reference state. However, ample experimental evidence shows that partial molar volumes in different phases are not the same in most cases. It will be shown that, in this case, the standard expression for the chemical potential does not adhere to the requirement that the chemical potential be a conservative property. A modification of the standard chemical potential expression is proposed to resolve this issue. The modification affects the Poynting correction in the vapor–liquid equilibrium equation and the osmotic equilibrium equation.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"7 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218826","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}

PLA-based temporary plugging agents have attracted extensive attention due to their high mechanical strength and environmental friendliness. However, their relatively low softening temperature and poor balance between stiffness and toughness significantly restrict their applicability in deep reservoirs. In this study, a composite biodegradable temporary plugging agent (CB-TPA) with stable interfacial adhesion morphology and excellent physical properties was prepared by a two-step reactive blending with polylactic acid (PLA), polyglycolic acid (PGA), polybutylene adipate terephthalate (PBAT), and a reactive elastomer (ADR). Experimental results indicated that at a PLA/PGA (70:30) to PBAT mass ratio of 3:1, the tensile strength, Vicat softening temperature, and impact toughness reached 64.4 MPa, 110 °C, and 7.7 kJ/m2, respectively. The material had a lower stiffness loss due to the improved compatibility, demonstrating well-balanced heat resistance, toughness, and stiffness. The simulated plugging experiments showed that CB-TPA could effectively withstand pressures up to 20 MPa at 160 °C, which is superior to that of commercial PLA temporary plugging agents. Under aqueous conditions at 160 °C, the weight loss of CB-TPA reached 96.7% within 4 h. The successful development of this composite biodegradable temporary plugging agent provides a new sustainable solution for the exploitation of deep unconventional oil and gas resources.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"1 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218830","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}

Herein, we accomplish a solvent-, metal-, and additive-free catalytic transformation of epoxides with CO2 under atmospheric pressure using an ionic polymer (H-IPyBPOH) as the catalyst. This polymer is synthesized via Friedel–Crafts alkylation between a phosphate-bearing hydrogen-bond donor and an imidazolium-based ionic linker. The resulting material contains potent hydrogen-bonding sites (P–OH), imidazolium cations, and bromide anions as nucleophiles. It exhibits excellent catalytic activity and recyclability for the cycloaddition of CO2 to epoxides. Combined DFT calculations and experimental results reveal that the high performance arises from the synergistic cooperation of hydrogen-bonding sites for epoxide activation, basic pyridine sites for CO2 activation, and bromide ions for the ring-opening attack. Moreover, the catalyst shows broad substrate compatibility and an outstanding structural stability. It can be easily recovered by filtration and reused for at least six cycles without a significant loss of activity.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"16 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218832","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}

To minimize this engineering limitation, Ag/CexTi1–xO2 (AgCeTi-x, x = 0.3, 0.5, and 0.7) monolithic catalysts were synthesized by loading the catalyst through a solvothermal method on a cordierite monolithic substrate. The Ce/Ti molar ratio was systematically varied to interrogate its influence on Ce3+ concentration, oxygen vacancy density, and Ag+/Ag0 concentration, as characterized by XRD, BET surface area, FE-SEM, XPS analysis, and H2-TPR analysis. XRD analysis confirmed the formation of a multiphase Ag/CexTi1–xO2 composite involving the coexistence of crystalline phases of metallic Ag, CeO2, and TiO2, and a unique broccoli-like structure with Ag as the floret and the metal oxide as the stem is evident for the AgCeTi-0.7 sample from FE-SEM and EDX analysis. Upon loading the catalyst onto the monolithic cordierite structure, the major diffraction peaks correspond to the cordierite phase, and the corresponding morphological modification was observed. Both powder and monolithic catalysts were compared for CO oxidation performance, and an inverse performance trend was observed for Ce-rich (x = 0.7) and Ti-rich (x = 0.3) samples, with the x = 0.3 (T50% = 100 °C) sample showing better results among the powder samples and the x = 0.7 (T50% = 87 °C) sample showing better results among the monolithic samples. Significant improvement in monolithic catalyst performance could be related to overcoming the transport limitations despite having lower Oβ vacant oxygen and lower dual-site Ag+/Ag0 ratios. This work demonstrates that material composition along with reactor architecture must be co-optimized as an inseparable design unit for efficient catalyst performance.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"28 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149209952","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}

Therefore, this study proposes a generative enhancement and manifold preservation-driven interpretable machine learning (GEMP-ML) framework. It integrates heuristic hybrid encoding, hierarchical missing value management, generative data augmentation, and active-learning-based sample screening to construct an information-enriched catalyst training set. To enable semantically faithful numerical representation of high-cardinality categorical features, a best-first sampling strategy is designed to identify the optimal hybrid encoding scheme from 89 candidate combinations specifically for these categorical variables. Combined with hierarchical semantic missing-value management and high-fidelity imputation algorithms, the data integrity of the CTA dataset is restored while preserving the semantic integrity of categorical features. GMM-based generative augmentation combined with diversity-aware active learning improved the utilization of synthetic data, and the CatBoost surrogate model achieved an average test set R2 of 0.973 across the three targets. Complementary interpretability analysis further identifies key descriptors governing catalyst performance, guiding the Pareto optimization of catalyst formulations and operating parameters. The recommended Zn–Al/HZSM-5 catalyst is predicted to achieve approximately 36.5% CO2 conversion, 78.6% C5+ selectivity, and 0.35% CO selectivity. The model is further validated against two independent experimental datasets covering 100 h time-on-stream, with prediction errors of <8%, supporting its ability to reproduce the observed performance trends under the evaluated conditions. This generalizable framework provides a systematic, data-driven paradigm for accelerating the design of high-performance catalysts in data-sparse catalytic systems.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"36 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149209954","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}

To overcome these limitations, a non-invasive, retrofittable wireless power transfer system is presented. The metallic vessel is structurally repurposed into a 5.23 GHz multi-mode microwave cavity resonator by coupling microwave energy through existing standard flanges. Electromagnetic simulations validate that this method generates continuous energy coverage throughout dynamic flow zones, demonstrated using a fluidized bed granulator as an application example.

Reaction conditions are systematically optimized, achieving an MCP conversion of 79.5% and a Co-adduct yield of 61.4%. Mechanistic investigations, including triplet quenching and radical trapping experiments, confirm that the reaction proceeds via a self-sensitized pathway involving triplet excited states and biradical intermediates.

After hydrodeoxygenation, a density of 0.949 g cm–3, a volumetric net heat of combustion of 40.46 MJ L–1 and an excellent freezing point (<−60 °C) are achieved for the synthesized spirocyclic fuel. Moreover, both the pure fuel and its blend demonstrated superior combustion, with minimum ignition temperatures of 280 and 275 °C, respectively, significantly lower than the reported value for JP-10 (380 °C).

This strategy not only achieves a uniform ion flux but also forms the solid electrolyte interphase (SEI) layer with high mechanical strength, thereby significantly improving the uniformity of Na+ distribution at the interface, which helps enhance the cycling stability of sodium metal batteries. Consequently, the sodium anode demonstrates a long cycle life of 1,300 cycles with a Coulombic efficiency (CE) as high as 99.97%.

Both CNCs and PFs resulted in a substantial enhancement of the mechanical properties.
