摘要： A system for detecting a chemical element within a material including at least one laser emission means for ionizing part of the material to generate fluorescence; at least one transmitting Bragg grating that filters the wavelength corresponding to the deexcitation wavelength of the element; and at least one photodiode that detects a line corresponding to the filtering wavelength, wherein the at least one Bragg grating is mobile to vary the filtering wavelength.

摘要： The invention relates to a method for processing an aqueous effluent (E) containing in solution at least one type of metal (M) nitrite or nitrate whose oxide is stable in an aqueous medium consisting (I) in introducing cations NH4+ in aqueous solution, generally in the form of an aqueous ammonia solution, into the aqueous effluent and, subsequently (II) in processing the obtainable medium at a temperature ranging from 100 to 700° C. and a pressure of 1-50 MPa (i.e. from 10 to 500 bar), thereby converting the metal (M) nitrite or nitrate into metal (M) oxide, nitrogen and water.

摘要： A method of manufacturing composite fibers comprising two distinct layers having different compositions and physico-chemical properties and controlled, homogenous thicknesses, wherein one of two layers comprises carbon nanotubes and the composite fibers are obtained from carbon nanotube fibers and a first solution of a selected concentration of colloidal particles intended to constitute the second layer, comprising the following steps: placing the fibers in contact, by lateral surfaces thereof, with a surface of a second solution which is adapted to chemically cause aggregation of the colloidal particles and is completely or partially immersed in the second solution, the immersed thickness of the fibers defining the immersion area, placing the thus pre-coated fibers in contract, on the same lateral surface, with a surface of the first colloidal particle solution and immersed in it at most up to the immersion area to locally form a colloidal gel with a fixed thickness determined by the concentration of the first solution, separating the fibers covered in the first solution, and drying and/or evaporating the solvent of the first solution.
