“…High surface free energy inhibits the cell-material interactions. A polar component gives information about wetting of the solid by a liquid [ 23 ]. The addition of phenolic acids to chitosan results in the increase in the polar component which suggests that the hydrophilicity of film increases.…”

This paper concerns the physicochemical properties of chitosan/phenolic acid thin films irradiated by ultraviolet radiation with wavelengths between 200 and 290 nm (UVC) light. We investigated the preparation and characterization of thin films based on chitosan (CTS) with tannic (TA), caffeic (CA) and ferulic acid (FA) addition as potential food-packaging materials. Such materials were then exposed to the UVC light (254 nm) for 1 and 2 h to perform the sterilization process. Different properties of thin films before and after irradiation were determined by various methods such as Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), atomic force microscopy (AFM), differential scanning calorimeter (DSC), mechanical properties and by the surface free energy determination. Moreover, the antimicrobial activity of the films and their potential to reduce the risk of contamination was assessed. The results showed that the phenolic acid improving properties of chitosan-based films, short UVC radiation may be used as sterilization method for those films, and also that the addition of ferulic acid obtains effective antimicrobial activity, which have great benefit for food packing applications.

Ti-based alloy, it is desirable to reduce its E to that of healthy bone (4-30 GPa) while maintaining its high strength and good plasticity [1][2][3][4][5][6][7][8]. Two approaches have been taken to achieve this goal. One is the production of metastable β type phase wrought niobium-titanium (Nb-Ti) alloys (for example, Nb50Ti), but the reported minimum value of E (60-62 GPa) is too high [9,10].Alternatively, porous Nb-Ti alloys, having a microstructure similar to that of cancellous bone, have been produced. Nb-Ti Intermetallic compound has been recognized as one of high temperature structural materials due to excellent physical, superconductivity and mechanical
