Osteoarthritis is marked by cartilage degeneration, whereas rheumatoid arthritis is characterized by synovial inflammation. Current treatments include pharmacological agents, physical therapy, and surgical interventions; however, these approaches have limited efficacy and may be associated with side effects. Therefore, tissue engineering has emerged as an innovative alternative for the repair of joint damage. In this study, bacterial cellulose (BC), chosen as the primary polymer for its superior mechanical properties, biocompatibility, and high water retention capacity, was combined with polylactic acid (PLA) and poly(3-hydroxybutyrate) (PHB) to design a bilayer scaffold system for bone and cartilage regeneration. To provide antimicrobial protection, vancomycin was incorporated into the nanofiber layer with the aim of achieving controlled release. The developed system supports cell proliferation and extracellular matrix (ECM) synthesis in cartilage tissue while enhancing mechanical strength and promoting osteogenic cell migration in bone tissue. Furthermore, it has the potential to slow cartilage degeneration in osteoarthritis, suppress inflammation in rheumatoid arthritis, and prevent infection-related damage. This integrated approach offers a multifunctional therapeutic platform aimed at complete osteochondral unit regeneration.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"33 9","pages":"5413 - 5435"},"PeriodicalIF":4.6,"publicationDate":"2026-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10570-026-07111-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148613198","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}

Environmentally friendly processes may include the use of enzymes to replace chemicals for the upgrade of Kraft pulps. In this work, the effect of enzymatic treatments on eucalyptus bleached Kraft pulp was evaluated using commercial Cellic enzyme cocktails CTec2 (CCT2) and CTec3 (CCT3) for the conversion of paper-grade pulp into dissolving pulp, comparing their performance with a single-component endo-glucanase from <i>Trichoderma reesei</i> (EGTr). Pulps were treated at two enzyme doses (10 and 100 IU/g), followed by acid hydrolysis, dissolution in NMMO solvent, and regeneration as hydrogels for cationic dye adsorption. Chemical analysis of the treated <i>Eucalyptus</i> pulps revealed an increase in carboxyl group content from 0.080 to 0.139 mmol/g after the application of 10 IU/g EGTr. However, at a higher enzyme dosage of 100 IU/g of EGTr, the carboxyl groups decreased to 0.103 mmol/g likely due to the partial reduction in xylans content in the treated pulps. The initial intrinsic viscosity of the bleached kraft pulp (642 mL/g), was reduced by 17.61% and 33.96% after treatments with 10 and 100 IU/g of EGTr, respectively. Among the treatments, hydrogels derived from 10 IU/g EGTr-treated pulps showed lower density (0.0437 g/cm³), higher porosity (96.92%) and a maximum methylene blue (MB) adsorption capacity of 22.9 mg/g. These values were similar to or higher than those obtained with the 100 IU/g treatments. In comparison, hydrogels derived from pulp treated with 10 IU/g of CCT2 and CCT3 cocktails showed bulk density of 0.0503 and 0.0505 g/cm³, a porosity of 96.49 and 96.45%, and maximum MB adsorption capacities of 20.4 and 19.9 mg/g, respectively. Control pulps that were only treated with alkaline extraction and acid hydrolysis exhibited the lowest adsorption capacity (17.1 mg/g). The superior performance of EGTr-treated hydrogels was positively correlated with increased carboxyl group content, which may reflect a secondary oxidative activity associated with the enzyme.

Although poly(vinyl alcohol) (PVA) is a promising biodegradable alternative due to its excellent film-forming ability, flexibility, and non-toxicity, its inherent water sensitivity and comparatively higher cost limit its widespread adoption. This study addresses these limitations by introducing citric acid (CA) to enhance water-barrier performance through hydrogen-bond modification, and by partially substituting PVA with cellulose-rich natural fillers, jute, and water hyacinth (WH), to reduce material cost. The combined use of jute and WH offers complementary advantages: jute contributes higher crystallinity and tensile strength, while WH provides ecological value as an invasive aquatic biomass. Despite their individual use in PVA composites, the synergistic influence of co-reinforcing PVA with both jute and WH, alongside CA-mediated interfacial modification, has not been systematically investigated, which is the focus of this study. Composite films were fabricated with a constant 70/30 (PVA/filler) ratio, both with and without CA addition. The CA-containing film achieved a contact angle up to ~ 79°, compared to pristine PVA (45°), indicating enhanced hydrophobicity. The tensile strength decreased moderately from 46.7 MPa (PVA) to 28–35 MPa for CA-containing films, yet remained within the range suitable for packaging use. The vapor transmission was reduced by ~ 35% and TGA showed higher char yield (up to 34%) for CA-containing films, confirming improved thermal and barrier stability.

However, the crystallinity and phase purity of cellulose III are not intrinsic properties of the allomorph itself, but depend strongly on preparation conditions. In this study, we developed an infrared (IR) spectroscopy–based machine learning approach for estimating cellulose III_I-equivalent content on a Rietveld-informed calibration scale. An ethylenediamine-treated cellulose III_I-rich reference sample was first reassessed by Rietveld refinement using cellulose III_I and cellulose Iβ structural models. The refinement indicated that the reference sample was not fully converted to cellulose III_I, giving fitted phase fractions of 49.7% cellulose III_I and 50.3% cellulose Iβ. The calibration targets were therefore calculated from the Rietveld-derived cellulose III_I fraction rather than from the conventional XRD peak-height index. Feature importance analysis using random forest (RF) identified the 1400–900 cm⁻¹ fingerprint region as the most informative spectral domain for cellulose III_I estimation. Restricting the model to this region reduced the number of spectral variables from 1764 to 260 while improving RF performance from R² = 0.955 and RMSE = 0.035 to R² = 0.975 and RMSE = 0.025. Application to ethylenediamine-treated commercial cellulose samples further demonstrated that the optimized RF model can provide physically reasonable estimates of cellulose III_I-equivalent content without requiring explicit XRD peak separation. This study shows that Rietveld-validated reference calibration combined with IR-based machine learning offers a practical and interpretable framework for rapid evaluation of cellulose allomorphic transformation.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"33 9","pages":"5131 - 5157"},"PeriodicalIF":4.6,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148613395","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}

Reactive dyes are the dominant class for dyeing cellulosic fibers because they exhibit high affinity and form covalent bonds with cellulose.

Therefore, removal of antibiotics from the contaminated wastewater is quite essential for making the aquatic ecosystem clean and sustainable. Recently, the implementation of nanocatalysts has been considered as one of the promising approaches to addressing the issue of wastewater treatment by removing antibiotic residues through photocatalytic degradation or adsorption techniques. In this context, carbon quantum dots (CQDs), because of their unprecedented catalytic properties, have been identified as a potential carbon-based nanomaterial. Furthermore, the preparation of CQDs can be performed by using waste biomass by employing them as a carbon source. Herein, as an abandoned bioresource, coconut biomass can be exploited to produce CQDs and their nanocomposites. Therefore, this review analyses the compositional structure and availability scope of coconut biomass along with exploring the development of CQDs via different methods and evaluating their physicochemical properties. Furthermore, the review shows that the biomass-derived CQD-based nano-photocatalysts and nano-absorbents show improved antibiotic removal efficiency by means of photocatalysis and adsorbing processes compared to their counterpart made from pure carbon. Therefore, the prospects of coconut biomass derived CQDs for their integration with nanomaterials for developing nano-photocatalysts and nano-adsorbents have been presented towards the removal of antibiotics. Furthermore, the possible mechanisms involving the antibiotic removal through nano-photocatalytic degradation and adsorption techniques have been discussed along with possible limitations and key challenges in this research area.
