20100189899 | METHOD AND DEVICE FOR THE INFILTRATION OF A STRUCTURE OF A POROUS MATERIAL BY CHEMICAL VAPOUR DEPOSITION - A method and a device for infiltration of a structure made of a porous material by chemical vapor deposition. According to the method, a first face of the porous material structure is exposed to a gaseous flow, and the second face is maintained at least partially free from any contact. | 07-29-2010 |
20110220024 | DEVICE FOR THE SYNTHESIS OF NANOPARTICLES BY FLUIDIZED-BED CHEMICAL VAPOUR DEPOSITION - A device for vapor deposition of chemical species on support grains of spherical or similar shape disposed in a fluidized bed. The device includes a first chamber including a fluidized bed in which a funnel-shaped fluidizer element is housed to receive support grains of spherical or similar shape; a second chamber in fluid flow connection with the first chamber to deliver precursors in a vapor phase of chemical species to be deposited on the support grains and to convey a fluidizing gas towards the first chamber; and a flute at an inlet to the fluidizer element to control distribution of the vapor phase precursors and the fluidizing gas within the fluidizer element. The distributor flute includes one or more outer grooves, each groove including a first portion oriented along the longitudinal axis of the flute and a second portion winding helically around the axis to generate a fluidizing gas vortex within the first chamber. | 09-15-2011 |
20140377650 | ASSEMBLY CONSISTING OF A CURRENT COLLECTOR AND A SILICON ELECTRODE - The invention relates to an assembly comprising a current collector and a silicon electrode, wherein the current collector and the electrode are connected together via at least one of the surfaces thereof by an elastic polymer layer. The invention can be used in the field of lithium batteries. | 12-25-2014 |
20150360192 | GELLED CAPSULES, AND REINFORCED LYOPHILISED GELLED CAPSULES, CONTAINING NANO - OBJECTS, AND PROCESSES FOR PREPARING SAME - A reinforced gelled capsule comprising a solvent, in which are distributed in a homogeneous manner nano-objects, and/or sub-micron objects, and/or nanostructures, coated with macromolecules of polysaccharide(s), the said macromolecules forming, in at least one part of the capsule, a gel by cross-linking with the cations of at least one element, and in which the external surface of the capsule is covered with crystals made of hydroxide of said element. | 12-17-2015 |
