Summary: Nanotechnology has enabled the development of biocompatible nanofibers in the healthcare industry. In this study, a cellulose acetate electrospun membrane was characterized with nanofibers of a certain diameter and pore size, which resulted in excellent air-water transfer properties. The tensile strength of the membrane was reinforced through the addition of waterborne polyurethane and graphene oxide coatings. The coated membrane maintained comparable air permeability and water vapor transmission rate, and exhibited rapid wetting transition. These achievements have important implications for filtration and wound dressing applications.

Summary: Rapid global industrialization has exacerbated the contamination of heavy metals in aquatic ecosystems. In this study, green, ultrafine cellulose-based porous nanofibrous membranes were developed for efficient removal of heavy metals by incorporating chitosan and using electrospinning techniques. The conventional electrospinning method resulted in a more uniform distribution of chemically active sites, leading to improved adsorption performance and reduced surface shrinkage during adsorption. The 30% CS conventional nanofibrous membranes exhibited the highest adsorption capacity for copper ions at a solution pH of 5.

Summary: Cellulose and its derivatives are commonly used as nanofibrous biomaterials, but research on obtaining 3D cellulose nanofibers is limited. This study presents a simple method for converting electrospun 3D cellulose acetate/lactic acid nanofibers into a 3D cellulose/calcium lactate nanocomposite matrix, resulting in a stronger and more cell-friendly material suitable for bone tissue engineering. The successful conversion was verified through various analytical techniques, and the scaffolds were found to provide a suitable environment for cell growth and infiltration.

Summary: Recycling biomass waste into functional materials through rational structural design has gained significant attention. In this study, a core-sheath structure was developed using co-axial electrospinning, where a mixture of cellulose acetate and chitosan was used as the sheath layer to efficiently adsorb humic acid, and waste cotton fabric-derived cellulose nanocrystals were incorporated as load-bearing components in the core. Compared to non-layered fibers, the core-sheath fibers exhibited smaller diameters, greater homogeneity, and improved mechanical strength, while maintaining similar adsorption capacities towards humic acid. Even after complete hydrolysis, the electrospun fibers maintained their fibrous structures with higher tensile strength and acceptable adsorption capacity towards humic acid. Therefore, this work highlights the importance of rational design in the efficient preparation of functional materials and demonstrates the feasibility of using electrospun core-sheath fibers derived from biomass wastes for water contaminant removal.

Summary: The aim of this study was to investigate the interface between cellulose acetate (CA) and viscose (CV) in an all-cellulosic compound and to evaluate the feasibility of hydrophobic CA-coatings on viscose fibers. The mechanical strengths of cellulose foil-CA compounds were compared to pure CA samples. The effects of CA coating on CV fibers were investigated by pretreating the fibers and determining their properties.

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.

Summary: The potential of multi-layer nanoemulsions for improving the cellular uptake, antioxidant activity, and in vitro bioaccessibility of alpha-tocopherol was examined. The results showed that the multi-layer nanoemulsions significantly enhanced the cellular uptake and antioxidant activity of alpha-tocopherol compared to free coumarin 6. Furthermore, the use of chitosan and dextran sulfate as wall materials in the multi-layer nanoemulsions led to even higher cellular uptake, in vitro bioaccessibility, and antioxidant activity of alpha-tocopherol.
