NANOSTRUCTURED ANODE MATERIAL FOR Li-ION BATTERY OBTAINED BY GALVANIC PROCESS
2016
The accumulation of energy by batteries plays a fundamental role for the production of electrical energy and for its efficient management. Between different storage systems the lithium-ion battery are considered very interesting. Although they are now a well-established commercial reality, they are still subject of vigorous research efforts, in order to make improvements primarily in terms of costs, safety and energy density. The latter is in fact still low compared to that of fossil fuels, if you think to the automotive field. In particular efforts are focused towards the identification of valid alternatives to the electrode materials so as to overcome the limitations and extend the use of…
Deposition and characterization of Hydroxyapatite-Chitosan coatings on 304 SS for biomedical devices
2019
During the last years biomaterials have been largely investigated in order to perform and improve biomedical devices. As regards orthopedic field, the most common equipment used (such as implants, bone grafts or screws) are constituted by metallic materials (steel and titanium alloys), characterized by low/medium resistance to corrosion and low osteointegration ability. Furthermore, these factors could produce local inflammations of the tissues surrounding the implants, increasing kinetics of corrosion phenomena. Scientific community has focused the attention on biocoatings interposed between metal and aggressive environment in order to inhibit corrosion. Furthermore, these coatings are abl…
