Ensuring quality and production efficiency for composite manufacturing requires optimal curing and processing conditions without compromising the structural integrity. Traditionally, techniques such as differential scanning calorimetry (DSC) and dynamic mechanical analysis are used to optimize curing conditions. Still, these methods are confined to the laboratory and may not accurately reflect curing behavior during composite production. Herein, we have used a thin, flexible, and cost-effective screen-printed cellulose paper sensor for real-time cure monitoring of flax fiber-reinforced bio-epoxy composites. The sensor-enabled online monitoring of the composite curing behavior during the vacuum infusion process was carried out at various temperatures. The sensor demonstrated excellent reproducibility and durability under different temperature conditions, and the online monitoring results showed a good correlation with the DSC cure kinetic model. Furthermore, the fibrous structure of the paper-based sensor contributes to the mechanical integrity of the composite, offering reinforcement benefits. The sensor’s facile fabrication, low cost, and reinforcement characteristics present significant potential for improving process control and enhancing the production efficiency of composite structures while ensuring stringent quality control.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 5","pages":"3173 - 3188"},"PeriodicalIF":4.9,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143784174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a GO-based composite with high adsorption capacity and reduced GO content was synthesized by incorporating TEMPO-oxidized cellulose nanospheres (TO-CNS) derived from pineapple leaves. TO-CNS were effectively integrated into GO via a one-pot reaction based on Hummer’s method. In this process, TEMPO oxidation selectively converted the –CH<sub>2</sub>OH groups on cellulose nanospheres into –COOH groups, all while preserving the crystalline structure of cellulose I. Notably, the in situ integration of TO-CNS as a co-support during graphite oxidation significantly enhanced the interlayer spacing of GO sheets, expanding it from 0.34 to 0.85 nm. This increase in spacing, indicative of robust interfacial interactions, was further validated using FTIR spectroscopy. The spectra revealed hydrogen bonding and pronounced shifts in the mode and position of the functional group peaks, underscoring the structural alterations induced by TO-CNS integration. Raman spectroscopy revealed increased graphitic defects, and thermal analysis confirmed structural integration. The composite's average pore size of 40 Å demonstrated a significant enhancement that facilitated adsorption compared to 26 Å in GO. Ciprofloxacin adsorption capacities (35.95 ± 0.54–38.47 ± 0.53 mg/g) were comparable to pure GO (35.08 ± 1.10–36.83 ± 1.12 mg/g) despite a reduced GO content (73.8/26.2 wt%). Zeta potential analysis highlighted the roles of electrostatic attraction, hydrogen bonding, and π–π stacking in adsorption. This GO/TO-CNS composite demonstrates the potential for efficient, sustainable, and biocompatible antibiotic adsorption, offering significant promise for environmental remediation.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 5","pages":"3317 - 3334"},"PeriodicalIF":4.9,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143784145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the early twentieth century, the term “fiber saturation point” was coined to refer to the point of transition from the domain where wood properties change with moisture content to the domain where wood properties are constant. This conceptual model assumed that the wood cell walls are water saturated at this transition point and that capillary water appears above this point. This has since then been contradicted by multiple studies. Additionally, the fiber saturation point has been associated with techniques that do not necessarily measure the same moisture state. Some techniques characterize either the transition state at which wood properties change, or the state at which the cell walls are water saturated. These are, however, not the same moisture state. The aim of this paper is to clarify which moisture states the various fiber saturation points represent discussed from a conceptual model consistent with current experimental evidence. To avoid confusion, we propose that the transition state at which wood properties change is the only state called “the fiber saturation point”, or, for even more clarity, “the property intersection point”. For other moisture states, we strongly recommend that the term fiber saturation point is avoided. The term “maximum cell wall moisture content” should be used for the state at which the cell walls are water saturated. Finally, we highlight the importance of considering which moisture state is relevant for a specific application and selecting an appropriate method to characterize that state.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 5","pages":"2901 - 2918"},"PeriodicalIF":4.9,"publicationDate":"2025-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10570-025-06412-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143784106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although CNFs are naturally attracted to atmospheric moisture, surface functionalization is needed to generate sufficient electricity through dissociation and diffusion of oppositely charged ions. We used a heterogeneous bilayer film system based on CNFs that were chemically modified with carboxylate and quaternary ammonium functional groups to assemble a moisture-enabled electric generator (MEG) by inducing a heterogeneous distribution of mobile ions. The MEG bilayer consists of functionalized CNFs with optimum thickness and area, which enables ion dissociation and diffusion through a continuous ion-concentration gradient even at a high relative humidity (> 95%). The streaming potential and ion gradient acting on the bilayer enhance the output performance of the MEG. The thickness of the bilayer film, along with temporal variations, also influences device performance. A single unit can spontaneously produce approximately 0.7 V and 0.8 µA of output voltage and current, respectively, without the need for an external power source. When 20 MEG units are combined, they can produce up to 9.6 V of output voltage and can supply continuous energy for several hours at a power density of 7.4 µW/cm<sup>2</sup> by storing power in capacitors. This study provides a better understanding of high-performance cellulose-based MEGs for self-powered devices.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 5","pages":"3285 - 3298"},"PeriodicalIF":4.9,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10570-025-06441-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143784099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
