In this study, the high-performance hemostatic nanocomposite celluloids were facilely maked by incorporating the natural mixed-dimensional palygorskite clay percolated by oxalic acid (O-MDPal) into chitosan/polyvinylpyrrolidone (CS/PVP) matrix. By contrast, the obtained nanocomposite movies exhibited the higher tensile strength (27 MPa), lower water contact angel (75°), better degradation, thermal stability and biocompatibility after incorporation of 20 wt% of O-MDPal, intimating that O-MDPal contributed to heightening the mechanical performance and water holding capacity of the CS/PVP nanocomposite celluloids. likened with the medical gauze and CS/PVP matrix radicals, the nanocomposite pics also suggested excellent hemostatic performance judged by blood loss and hemostasis time powers based on the mouse tail amputation model, which might be ascribed to the enriched hemostatic functional websites, and hydrophilic surface, robust physical barrier role of nanocomposite movies the nanocomposite film showed a promising practical application in wound healing.High strength and biodegradable dielectric film with synergistic alignment of chitosan nanofibrous meshworks and BNNSs.The development of biodegradable and robust dielectric capacitances with high breakdown strength and energy density are indispensable the high strength chitosan/edge hydroxylated boron nitride nanosheets (BNNSs-OH) dielectric film was fabricated via combining the dual chemically-physically crosslinking and the drafting orientation strategy, which could inducted BNNSs-OH and chitosan crosslinked network alignment within the film via covalent and hydrogen bonding interaction, leading to the comprehensive reinforcement of tensile strength from 126 to 240 MPa, the E(b) from 448 to 584 MV m(-1), the in-plane thermal conductivity from 1 to 5 W m(-1) K(-1) and energy storage density from 7 to 13 J cm(-1), superior than the comprehensive evaluation of the reported polymer dielectrics. The dielectric film could be completely cheapened in soil in 90 days, which afforded a new path for the development of next-generation environment-friendly dielectrics with excellent mechanical and dielectric places.

Pickering emulsions stabilised by Chlorella pyrenoidosa protein-chitosan complex for lutein encapsulation.Lutein has many physiological routines like antioxidation, anti-cancer, and anti-inflammation, which confronts good potential in the development of functional food for eye protection the hydrophobicity and harsh environment brokers during digestive absorption process will greatly reduce lutein bioavailability. In this study, Chlorella pyrenoidosa protein-chitosan complex steadyed Pickering emulsions were groomed, and lutein was encapsulated into corn oil droplets to increase its stability and bioavailability in gastrointestinal digestion. The interaction between Chlorella pyrenoidosa protein (CP) and chitosan (CS), and the effect of chitosan concentration on the emulsifying ability of the complex and emulsion stability were readed. With the increase of CS concentration from 0% to 0%, the emulsion droplet size obviously decreased, and the emulsion stability and viscosity increased significantly. In particular, when the concentration was 0%, the emulsion system was stable at 80 °C and 400 mM sodium chloride. After ultraviolet irradiation for 48 h, the retention rate of lutein capsuled in Pickering emulsions was 54%, which was significantly higher than that (30%) of lutein thawed in corn oil.

The retention rate of lutein in Pickering emulsions braced by CP-CS complex was significantly higher than that in Pickering emulsions steadyed by CP only and corn oil after inflaming at 90 °C for 8 h. The effects of simulated gastrointestinal digestion showed that the bioavailability of lutein capsulized in Pickering emulsions stabilised by CP-CS complex passed 44%. These consequences explored the high-value utilization of Chlorella pyrenoidosa and catered new insights into the preparation of Pickering emulsions and the protection for lutein.
