Abstract: The present invention relates to a biomedical device for the distribution or containment of biological substances comprising at least two components assembled each other with an adhesive composition comprising a mixture of an acrylic adhesive composition and an epoxy adhesive composition. The present invention also relates to a method for assembling a biomedical device comprising at least two components, comprising (i) forming a film of an adhesive composition comprising a mixture of a (meth)acrylate adhesive composition and an epoxy adhesive composition on at least one surface of said at least two components, (ii) pre-curing said adhesive composition with an UV-blue radiation exposure to substantially cure said (meth)acrylate adhesive composition without substantially curing said epoxy adhesive composition, (iii) contacting said at least one surface of said at least two components to be assembled, and (iv) completing the curing of said adhesive composition with an UV-blue radiation exposure.

Abstract: An optical channel (OC) is produced in a tellurite glass (T) by selectively (M) exposing the glass surface to UV laser radiation (L), whereby the exposed areas define an optical channel (OC) photoinduced in the glass (T). The UV laser radiation (L) has a wavelength around 240-270 nm or around 193 nm and may be both continuous wave and pulsed laser radiation. The core of an optical waveguide (OC) can thus be produced in the tellurite glass (T), while a cladding may be provided by means of glass or polymer spinning, sol-gel or other conventional techniques.

Abstract: In order to fabricate strip monomode active optical waveguides for optical elecommunications, a layer of vitreous soot is deposited on a substrate and is impregnated with a solution of a precursor of a rare-earth dopant, and a radiation with a wavelength comprised in an absorption band of the dopant is moved along the soot, along a trajectory corresponding to the geometrical shape desired for the guide, thereby forming a vitrified strip.

Abstract: An article for use in producing silica optical fibers doped with a metal de obtained by synthesis from low pressure vapor reactants is made from an outer supporting tube extending along a longitudinal axis and having first and second longitudinally opposite ends and an inner surface on which silica and a dopant formed by a reaction between vapor-state reactants can be deposited over a longitudinally extending silica-deposition zone. Respective first and second joints engage the ends of the supporting tube and each have a fixed part and a rotating part. Each rotating part supports the respective end for rotation relative to the respective fixed part about the axis. At least one of the reactants is introduced into the supporting tube through the first joint and depleted gases are discharged through the second joint.

Abstract: Silica intended to form the core of an optical-fibre preform is deposited as an unvitrified soot inside a reaction tube, where a non-aqueous solution of dopant precursor(s) is then introduced without removing the tube from the lathe. The precursor(s) of the dopant(s) are dissolved in an anhydrous organic solvent. The solution containing the dopant precursor(s) is introduced into the reaction tube without removing the tube from the lathe so that the solution covers the whole surface of the deposited soot layer and impregnation of the deposited soot layer occurs.
