The palladium metal nanoparticles doped on the modified chitosan nanofibers with 2-aminobenzaldehyde (CSNFs-2-ABÀ Pd (0)) were thoroughly characterized and applied as a novel heterogeneous catalyst in Heck and Suzuki CÀ C coupling reactions. This catalyst is exceptionally simple to handle and ecologically safe and temperate. The catalyst was essentially reused from the reaction mixture and reused sequential five times with low leakage. CSNFs-2-ABÀ Pd (0) was characterized using scanning electron microscopy, transmission electron microscopy, X-ray diffraction, energy-dispersive X-ray spectroscopy and Fourier transform infrared.

Among the commonly used nanofibers production methods, electrospinning has many advantages such as ease of production, possibility of industrialization, nanofibers dimensional control and repeatability. Many parameters affect the characteristics of the nanofibers produced by this method, the most important of these parameters being the applied voltage, the concentration of polymer solution, the sample injection rate, the distance between the needle and the collector, and environmental factors too. Pharmaceutical properties of nanofibers are determined by their composition and structure at the nanoscale. Therefore, the ultimate goal of identify nanostructure and nanofiber morphology must be searching for an atom to an atom on a surface and under the reaction conditions. In this paper, honey nanofibers enriched with antibacterial herbal extracts such as the garlic, mint and edible mushroom are produced by method of electrospinning, by reviewing the effective conditions in preparing them, to achieve nanostructures and optimize conditions. The related nanofibers have ability to repair and regenerate damaged skin and bone tissues as an effective drug, which is especially important for biocompatibility and economics. In this research, nanofibers have been investigated by examining cases affecting structure and performance. The hydroalcoholic extracts and nanofibers are identified by device methods such as GC-Mass (gas chromatography-mass spectrometry), FT-IR (Fourier transform infrared spectroscopy), SEM (scanning electron microscopy) and XRD (X-ray diffraction spectroscopy).
