Abstract: A process for the manufacturing of 3D reduced graphene oxide/Fe2O3 material includes the following steps: (i) putting in contact a graphene oxide (GO) water dispersion with an aqueous solution of iron(II) sulfate; (ii) hydrothermal treatment; and (iii) freezing the reaction product obtained in step (ii) at a temperature ??5° C.; and (iv) lyophilisation. A 3D reduced graphene oxide/Fe2O3 material is obtainable by the process and further relates to electrodes for CDI devices having the material. A method for removing ions from a fluid, like saline water, using the capacitive deionization device includes applying a voltage to the electrodes while supplying the fluid into the capacitive deionization device.

Abstract: The invention relates to a method of producing medical prostheses or implants having a surface microroughness and/or an induced oxide layer, comprising a treatment involving the ionic implantation of controlled amounts of elements such as CO, C, H, N or O in endosseous implants or prostheses produced from metals, metal alloys or biocompatible composite materials. The surface treatment causes changes in the surface characteristics of the endosseous implants or prostheses in terms of nanoroughness, hydrophilic properties and chemical composition, significantly increasing the degree of osseous integration thereof.

Abstract: The method comprises the ion implantation of controlled quantities of elements such as CO, C or O in endo-osseous implants or prostheses manufactured in metals, metallic alloys or biocompatible compound materials. This surface treatment originates some modifications in the characteristics of the surface of the endo-osseous implants or prostheses which increases significantly their degree of osseointegration.
