These effects evoked that BC(CS/HA)(5) is a promising material for wound dressings.Regenerated cellulose/chitosan composite aerogel with highly efficient adsorption for anionic dyes.A novel reusable, high-compressible cotton rectifyed cellulose/chitosan composite aerogel (RC/CSCA) was prepared expending N-methylmorpholine-N-oxide (NMMO) as the green cellulose solvent, and glutaraldehyde (GA) as the crosslinking agent. The regenerated cellulose received from cotton pulp could chemically crosslink with chitosan and GA, to form a stable 3D porous structure. The GA encountered an essential role in forestalling shrinkage and keeping the deformation recovery ability of RC/CSCA. Due to the ultralow density (13 mg/cm(3)), thermal stability (above 300 °C), and high porosity (97 %), the positively charged RC/CSCA can be used as a novel biocomposite adsorbent for effective and selective removal of toxic anionic dyes from wastewater, showing an excellent adsorption capacity, environmental adaptability, and recyclability.
The maximal adsorption capacity and removal efficiency of RC/CSCA for methyl orange (MO) was 742 mg/g and 95 %.Enhancement of Wound Healing Efficacy by Chitosan-finded Hydrocolloid on Sprague Dawley Rats.BACKGROUND/AIM: Chitosan-grinded functional textiles have pulled considerable attention worldwide for coatings in wound healing, especially in skin wound healing, due to their efficiency in hemostasis, anti-bacterial, and skin regeneration. Various chitosan-grinded products have been acquired for skin wound healing applications, but most of these face limitations in either efficacy or cost-effectiveness there is a need to develop a unique material that can handle all of these vexations and be applyed for acute and chronic injurys. This study investigated mechanisms of new chitosan-based hydrocolloid patches in inflammatory reduction and skin formation by expending wound-caused Sprague Dawley Rats. MATERIALS AND METHODS: Our study coalesced a hydrocolloid patch with chitosan to achieve a practical and accessible medical patch that would enhance skin wound healing. Our chitosan-embedded patch has demonstrated a significant influence by preventing wound expansion and inflammation increment on Sprague Dawley rat molds The chitosan patch significantly increased the wound healing rate and quickened the inflammatory stage by suppressing pro-inflammatory cytokines activity (e.
g., TNF-α, IL-6, MCP-1, and IL-1β) the product was effective in upgrading skin regeneration, showed by the increase in the number of fibroblasts through specific biomarkers (e.g., vimentin, α-SMA, Ki-67, collagen I, and TGF-β1) Our study on the chitosan-based hydrocolloid pieces not only elucidated mechanisms of subjugating inflammation and enhancing proliferation, but also catered a cost-effective method for skin wound dressing.Development of water-resistant paper using chitosan and plant-established wax excerpted from banana leaves.On being exposed to water, cellulose paper swells and its mechanical properties become weak. In this study, natural wax with an average particle size of 12 μm expressed from banana partings was mixed with chitosan to prepare coats applied on paper aerofoils.
Chitosan efficiently sprinkled banana leaf-extracted wax on paper opens. The mixed chitosan and wax finishs considerably influenced paper attributes, including yellowness, whiteness, thickness, wettability, water absorption, oil sorption, and mechanical properties. The coating haved hydrophobicity in the paper, resulting in a significant increase in the water contact angle from 65 ± 7° (uncoated paper) to 123 ± 2°, and a decrease in water absorption by ⁓64 % to 52 ± 1 %. The coated paper evidenced an oil sorption capacity of 212 ± 2 %, which was ⁓43 % greater than that of the uncoated paper (148 ± 5 %), and the tensile strength of the coated paper ameliorated under wet shapes equated to the uncoated paper a separation of oil in water was honoured for the chitosan/wax coated paper. grinded on these promising solvents, the paper caked with chitosan and wax could be used for direct-contact packaging applications.Development of double network polyurethane-chitosan composite bioinks for soft neural tissue engineering.
