    Abstract There is a growing interest in utilizing renewable biomass resources to manufacture environmentally friendly active food packaging, against the petroleum-based polymers. Cellulose nanofibers (CNFs) have received significant attention recently due to their sustainability, biodegradability, and widely available sources. CNFs are generally obtained through chemical or physical treatment, wherein the original surface chemistry and interfacial interactions can be changed if the functionalization process is applied. This review focuses on promising and sustainable methods of functionalization to broaden the potential uses of CNFs in active food packaging. Novel aspects, including functionalization before, during and after cellulose isolation, and functionalization during and after material processing are addressed. The CNF-involved structural construction including films, membranes, hydrogels, aerogels, foams, and microcapsules, is illustrated, which enables to explore the correlations between structure and performance in active food packaging. Additionally, the enhancement of CNFs on multiple properties of active food packaging are discussed, in which the interaction between active packaging systems and encapsulated food or the internal environment are highlighted. This review emphasizes novel approaches and emerging trends that have the potential to revolutionize the field, paving the way for advancements in the properties and applications of CNF-involved active food packaging.

    Abstract Recently, cellulose nanofibers (CNF) have gained significant attention as renewable and high-value nano-biomaterial that has the potential to regulate microstructures and enhance the strength properties of paper products. However, the distribution of CNF in paper sheets may impact the physical properties differently, requiring further understanding. In this study, the effects of different CNF distributions on pore sizes and strength properties in paper sheets were investigated. The hypothesis is that the different distributions of CNF within paper sheets can exhibit different functions in improving the physical properties of paper sheets. Three types of paper sheets containing CNF were respectively prepared by mixing with pulp (CNF (mixture)), distribution on the surface of paper sheets (CNF (surface)) and adding in the middle of paper sheets (CNF (middle)). Results show that CNF can narrow the pore size distribution of paper sheets, particularly in samples with CNF (surface) and CNF (middle) that form dense CNF layers. The highest mechanical strength improvement was observed with mixed CNF. X-ray photoelectron spectroscopy (XPS) analysis revealed that this is due to the strong hydrogen bonding between CNF and pulp fibers, resulting from a large bonding area and effective contact with pulp fibers. This study provides a new perspective on CNF distribution within paper sheets for improving wet web strength properties.

    Abstract Starch based bio-latex has been widely researched in the coating paper area for the purpose of partial replacement of petroleum-based binders. In this paper, a green and facile ball milling pretreatment was proposed to modify the starch granules before α-amylase hydrolysis by breaking up their crystalline structure, thus improving the accessibility and susceptibility of amylase into starch structure. It was found that the improved hydrolysis process after 8 h ball milling can generate suitable degree of polymerization of polysaccharides or oligosaccharides, which further facilitated the following H

    Abstract The properties of wet-web strength and pressability of base paper affect the frequency of sheet breaks and machine runnability during the paper-making process. In this paper, the effect of nano-fibrillated cellulose (NFC) on the wet-web strength and pressability of paper sheet during the press process of paper-making was explored. It was found that the tensile energy absorption (TEA) of the sample was increased from 6.32 to 10.93 J/m

    Abstract In recent years, cellulose nano-fibers (CNF) have been regarded as renewable, promising reinforcer to enhance the strength property of paper products. In this paper, the roles of cationic cellulose nano-fibers (CCNF) as versatile flocculants of wood pulp and fines in pulp slurry for high wet web performance have been studied. It was found that CCNF can induce significantly flocculation (CCNF-Fines complex) in pulp slurries. The mechanical properties of wet web can also be improved by the addition of CCNF. The study demonstrated that CCNF can act as effective flocculants of fines and form CCNF-Fines complex for improved wet-web strength, in addition, CCNF has little effect on the dewatering rate of wet-web. CCNF is more beneficial to the wet web performance when it is in higher charge density. The research paves a way to further study the comprehensive application of CCNF in the wet-web making process for high performance.

    Abstract Purpose: The aim of this study was to compare diffusion-weighted magnetic resonance imaging (DWI) with computed tomography perfusion (CTP) for preoperative detection of metastases to lymph nodes (LNs) in head and neck squamous cell carcinoma (SCC).
    Methods: Between May 2010 and April 2012, 30 patients with head and neck SCC underwent preoperative DWI and CTP. Two radiologists measured apparent diffusion coefficient (ADC) values and CTP parameters independently. Surgery and histopathologic examinations were performed on all patients.
    Results: On DWI, 65 LNs were detected in 30 patients. The mean ADC value of metastatic nodes was lower than benign nodes and the difference was statistically significant (P < 0.05). On CTP images, the mean value in metastatic nodes of blood flow (BF) and blood volume (BV) was higher than that in benign nodes, and mean transit time (MTT) in metastatic nodes was lower than that in benign nodes. There were significant differences in BF and MTT values between metastatic and benign LNs (P < 0.05). There were significant differences between the AUCs of DWI and CTP (Z=4.612, P < 0.001).
    Conclusion: DWI with ADC value measurements may be more accurate than CTP for the preoperative diagnosis of cervical LN metastases.
