摘要： The invention relates to a process for selectively and continuously extracting a series of desired species from a matrix, comprising the steps of:—injecting a plasma (310) in an extraction chamber by means of a plasma torch,—continuously monitoring (320) the excited elements extracted from the matrix and contained in the plasma by optical emission spectroscopy, and for each species of the series,—setting a distance (330) between the support and the plasma torch, and the composition of the injected plasma as a function of the monitored excited elements so that only one desired species of the series of species is being extracted from the matrix under molecular form, and—providing (400) a plate in the extraction chamber, exterior to the plasma, causing collection of molecules comprising said desired species by deposition onto the surface of the plate.

摘要： The invention relates to a ternary Titanium-Zirconium-Oxygen (Ti—Zr—O) alloy, characterized in that it comprises from 83% to 95.15 mass % of titanium, from 4.5% to 15 mass % of zirconium and from 0.35% to 2 mass % of oxygen, with said alloy being capable of forming a single-phase material consisting of a stable and homogeneous a solid solution of Hexagonal Close Packed (HCP) structure at room temperature. The invention further relates to a method for producing such alloy as well as preferred applications and utilizations thereof.

摘要： According to a thermomechanical treatment process for a titanium alloy including between 23 and 27% niobium in atomic proportion, between 0 and 10% zirconium, and between 0 and 1% oxygen, nitrogen and/or silicon, the following steps are performed:a) an increase of a sample of the alloy to a temperature higher than 900° C.,b) a fast quench,c) a severe cold strain,d) an ageing treatment at a temperature included between 200 and 600° C., the time of the ageing treatment being included between 10 seconds and 10 minutes. Alloy obtained by this process and prostheses made from such an alloy.
