Summary: Due to irreversible aggregation, achieving nanoscale redispersion of cellulose nanofibrils has been challenging. This study proposed a re-watering strategy to achieve nanoscale redispersion of oven-dried TOCN in water. Water wetting-up was effective in achieving high redispersion rates, and the addition of sodium lignosulfonate further improved the redispersion rate. The redispersed TOCN exhibited no significant difference in mechanical properties and could be used as a proppant for fracturing fluids to improve their stability.

Summary: In this study, a nanocomposite film with excellent overall performance was prepared using CCNF1.2 as both a dispersant and reinforcement matrix for BNNS. The high aspect ratio of CCNF1.2 facilitates the dispersion of BNNS and provides strong repulsion force. Additionally, CCNF1.2 exhibits strong hydrophobic-hydrophobic interactions with BNNS and complete interaction through hydrogen bonding. As a result, the BNNS-CCNF1.2 film shows a compact aligned structure and superior comprehensive performance.

Summary: This study demonstrates the potential of TEMPO-oxidized cellulose nanofibrils (T-CNF)/poly(vinyl alcohol) (PVA) coatings to develop functionalized membranes with outstanding antifouling performance and stability in the ultrafiltration regime. The coated membranes showed nano-textured surface, altered surface charge, and improved mechanical properties compared to the original substrate. Additionally, the coated membranes exhibited charge specific adsorption and rejection driven by electrostatic interaction and size exclusion mechanisms, leading to reduced fouling when exposed to BSA and E. coli.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
