After the discussion committee recorded its observations on the thesis, which were divided between explanation, correction, the student’s defense of her message and the end of the discussion, the committee decided to evaluate the thesis and decided to grant the student a master’s degree with a passed. AbstractThis work aim to preparing NiTi/PVA composite nanofibers by electrospinning technique, using a novel method of producing NiTi ultrafine particles by immersing sintered NiTi alloy for a specific time in dilute aqua regia solution (3HCl: HNO3), in which these produced NiTi ultrafine particles are used in the electrospinning process. The electrospun materials provide a fibrous structure that improves adhesion with cells through the high surface area to volume ratio. The produced ultrafine NiTi particles were analyzed by X-ray diffraction (XRD), Energy dispersive spectroscopy (EDS), and Particle size analyzer. The XRD pattern of ultrafine NiTi particles showed much better phases as compared to the XRD pattern of the NiTi alloy sample.
