Summary: Multifunctional cotton fabric was prepared by coating AgBr-TiO2/OV-POSS nanocomposites using the spray coating method. The presence of AgBr-TiO2 nanoparticles and OV-POSS resulted in increased surface roughness and adhesion, leading to enhanced hydrophobicity and decreased surface energy of the fabric. The coated fabric exhibited excellent mechanical durability, chemical resistance, UV protection, self-cleaning properties, oil/water separation efficiency, methylene blue degradation, and antibacterial efficacy against K. pneumoniae and S. aureus.

Summary: Interference structural colors with excellent UV protection were achieved by coating SiO2/TiO2 composite multilayer films on polypropylene non-woven fabrics and polyester woven fabrics using magnetron sputtering. The positions and numbers of the strongest reflection peaks on the coated films matched theoretical calculations. The optical properties differed when depositing the same film on different substrates, with the PET substrate having higher reflectivity due to a higher refractive index. This research provides theoretical and practical guidance for structural coloration and functional fabrication on fabric substrates.

Summary: In this study, a simple and low-cost method was utilized to create multifunctional cotton fabrics with hydrophobic, self-cleaning, and UV protection properties. The cotton fabric surfaces were modified using a dip-pad-dry-cure coating technique with different concentrations of ZnO nanoparticles, and the self-cleaning properties were evaluated through hydrophobicity and contact angle measurements. Additionally, the chemical self-cleaning performance was examined by photocatalytic degradation of dye stains on ZnO coated fabrics under UV exposure.

Summary: Developing cellulose-based textiles functionalised with silver nanoparticles synthesized through a green approach is important for UV radiation and bacteria protection. Different plant extracts as reducing agents influenced the synthesis of AgNP on cotton, with the best UV protection achieved using Japanese knotweed rhizome extract. Regardless of the reducing agent, all cotton samples showed excellent protection against bacteria and UV radiation.

Summary: This study involved the formation of cellulose-based polyelectrolyte charge complexes with anticoagulant properties on the surface of biodegradable polycaprolactone (PCL) thin films. The mixed charged bilayers showed a significant BSA repellent character and increased total plasma coagulation time compared to neat PCL. The cellulose derivative-based coatings have the potential to prevent unwanted BSA deposition and fibrin clot formation on PCL surfaces for biomedical applications.

Summary: In this study, cellulose nanocrystals (CNCs) were isolated from Isora plant fibers by sulfuric acid hydrolysis and assembled on cellulose and silicon-di-oxide (SiO2) surfaces via a layer-by-layer (LBL) deposition method. The CNCs exhibited high stability, negative zeta potential, and were investigated for their multilayer structure, adsorbed mass, conformational changes, and anticoagulant activity. The study provided new possibilities for fabricating and tailoring physicochemical properties of multilayer films from polysaccharide-based nanocrystals for diverse biomedical applications.

Summary: The hybrid extrusion-based bioprinting process allows for the fabrication of mechanically advantageous scaffolds by integrating softer hydrogels into a stiffer synthetic framework. This approach enables the fine-tuning of wettability, swelling, degradability, and mechanical strength, while providing a gradient of surface properties and good biocompatibility for tissue engineering applications. The controlled degradability and permeability of the hydrogel component may also enable controlled drug delivery in these hybrid scaffolds.

Summary: Research focused on modifying the PTFE surface by sustaining ammonia plasma in the H-mode at 35 Pa and 200 W forward power, saturating the surface with nitrogen groups within one second. While the nitrogen-rich surface film persisted for several seconds, prolonged treatment caused etching. Pulsed ammonia plasma at the same pressure but with 25 W forward power in the E-mode led to more gradual functionalization without observed etching even after prolonged treatment for up to 100 s.
