In this study, we present a simple and scalable method involving dip-coating and spray-coating to produce multifunctional, wearable, high-performance MXene/CuS/cotton fabrics. Leveraging the conductive networks formed by synergistic MXene/CuS and the porous structure of the fabrics, these MXene/CuS/cotton fabrics demonstrate impressive electromagnetic interference (EMI) shielding effectiveness (51.1 dB at a thickness of 335 μm) and notable Joule heating performance (approximately 60 °C at a voltage of 6 V). Moreover, when pressure is applied, MXene/CuS/cotton fabrics exhibit negative piezoresistivity, high sensitivity (− 18.2 kPa⁻¹ for 1–4 kPa pressures), rapid response and recovery times (0.4 s), along with exceptional long-term durability and stability (over 2000 cycles).

Researchers looked at how well electron beam irradiation (EBI) pretreatment works on microcrystalline cellulose (MCC), which is a type of cellulose found in LB, using doses between 100 and 1000 kGy. The effectiveness of EBI pretreatment on MCC was measured using the lateral order index (LOI) for samples soaked in water, samples not soaked in water, and samples soaked in an ionic liquid (IL). The combination of the water solvent with EBI led to a greater LOI reduction percentage effectiveness (LOI%) of 25.40% for the water-soaked samples, while the samples treated with 50% (v/v) 1-ethyl-3-methylimidazolium acetate [EMIM]Ac as the IL alone showed a reduction of only 20.25%, and the non-soaked samples had a reduction of just 14.84%. However, EBI, water soaking, and IL pretreatments further reduced the LOI of MCC. In addition to this, significant ANOVA overall linear regression equation models (representing a <i>p</i>-value &lt; 0.05) for each of the EBI-MCC non-soaked, water-soaked and IL pretreatments were also reported. The MCC linear predictive equation from the EBI water-soaked method was validated using oil palm frond with the same approach, and it was found to be overestimated, with a Root Mean Squared Error (RMSE) of about 8%. In conclusion, significant prospects for EBI or [EMIM]Ac, which offer balanced techno-economic feasibility when replacing water solvent during the pretreatment of MCC representing LB, are only possible if the RMSE value indicates a higher accuracy between predicted and actual values of the crystalline state of LB. These findings open a new perspective on EBI-combinatorial pretreatment for future cost reduction.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 13","pages":"7659 - 7674"},"PeriodicalIF":4.8,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10570-025-06681-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145011984","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}

Among these, coconut fiber stands out as a promising agro-industrial residue for enhancing the bioeconomy due to its abundance. In this context, aiming to enhance the value of coconut byproducts, this study suggests of a more efficient method for extracting extractives, hemicellulose, and lignin from coconut mesocarp, thereby obtaining a cellulosic fraction appropriate for producing carboxymethylcellulose (CMC). The developed methodology employs a sequential pretreatment process that integrates alkaline extraction (NaOH 0.50 mol/L, 55 °C, 2 h) and organosolv (ethanol:water 1:1, alkaline catalyst, 2 h, 185 °C) techniques. Chemical and structural characterization analyses of both treated and untreated biomass reveal that sequential pretreatment is critical for the effective extraction of lignocellulosic fractions. A significant reduction in residual lignin content is seen, dropping from 43.31 to 11.41 in the treated sample, while cellulose content rises to 47%, resulting in a 22% yield of CMC. Changes in the chemical structure are confirmed by FTIR analysis, which reveals more distinct cellulose peaks in the sequentially treated samples. TGA and SEM analyses also support the removal of lignin and hemicellulose. This study introduces a novel method for producing CMC from lignocellulosic biomass through a sequential pretreatment that effectively removes non-cellulosic components from coconut fiber. Beyond increasing CMC production, this proposed process encourages the creation of innovative products and uses derived from lignocellulosic biomass. This initiative not only enhances sustainability but also optimizes the use of renewable resources, driving significant progress in the biorefinery sector.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 13","pages":"7553 - 7572"},"PeriodicalIF":4.8,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145011980","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}

This study explores the use of non-edible sea mango (<i>Cerbera</i> <i>odollam</i>) fibre waste as a source for cellulose and lignin extraction. Three types of ultrasound-assisted solvent systems were investigated, including zinc chloride, lithium bromide, and a deep eutectic solvent composed of choline chloride and lactic acid, followed by either dry or wet post-ball milling. Extracted lignin using an alkaline process was used to determine optimal solvent concentration and temperature for effective lignin dissolution. The most efficient conditions for lignin dissolution were found to be 40 wt% zinc chloride at 65 °C, 50 wt% lithium bromide at 80 °C, and a 1:10 molar ratio of choline chloride to lactic acid at 80 °C. Under optimized conditions developed by response surface methodology, the maximum cellulose yield obtained was 87.23%, with lignin and hemicellulose contents reduced to 4.10% and 3.95%, respectively, using the choline chloride/lactic acid solvent. The integration of wet post-ball milling further enhanced the cellulose content to 93.80%, representing a 3.04% improvement over dry milling. Successful cellulose extraction was confirmed through characterization, including functional groups, crystallinity index, morphological structure, and thermal stability analyses. Key findings included the detection of hydroxy, alkyl, and ether functional groups, an increase in crystallinity from 57.54 to 77.77%, and smoother fiber morphology comparable to commercial cellulose.
