20090209684 | USE OF A METAL ORGANOSILICATE POLYMER AS DISPERSION-FORMING AGENT - The invention relates to the use of a metal organosilicate polymer as a dispersion-forming agent. The metal organosilicate polymer used in the invention has one of the following formulae I and II: | 08-20-2009 |
20090270600 | SILICA PARTICLE COMPRISING AN ORGANOLANTHANIDE COMPOUND, PREPARATION PROCESS THEREFOR AND USES THEREOF - The present invention relates to a silica particle comprising at least one complex of at least one lanthanide and of at least one ligand of formula (A) | 10-29-2009 |
20090321660 | DISPERSIONS OF LUMINESCENT RARE-EARTH OXIDE PARTICLES, VARNISH COMPRISING THESE PARTICLES, THEIR METHODS OF PREPARATION AND METHOD FOR MARKING SUBSTRATES - Dispersion of particles of at least one oxide of at least one luminescent rare earth, disaggregated and stabilized in a hydrophobic liquid medium containing at least one surfactant, in which the said surfactant is a non-ionic surfactant having an HLB (hydrophilic-to-lipophilic balance) lower than 12. | 12-31-2009 |
20110086165 | METALLIZATION OF A POROUS SILICON ZONE BY IN SITU REDUCTION AND APPLICATION TO A FUEL CELL - A porous silicon zone is metallized by performing in situ reduction of metallic ions dissolved in an aqueous solution and fixing of the metallic particles obtained on said zone in a single step. This step consists in particular in bringing the solution containing the metallic ions into contact with the zone to be metallized, the surface whereof has previously been functionalized to enable in situ reduction of the metallic ions and fixing of the metallic particles. Functionalization of the porous silicon zone is achieved by grafting two particular and distinct types of chemical functions. The first function used is a chelating chemical function for the metallic ions and/or for the metal corresponding to the metallic ions, whereas the second function is a reducing chemical function for the metallic ions. Such a metallization can be used for producing an electrically conducting porous diffusion layer of a fuel cell. | 04-14-2011 |
20110104811 | COATED AND FUNCTIONALIZED PARTICLES, POLYMER CONTAINING SAME, METHOD FOR PREPARING SAME AND USES THEREOF - The present invention relates to a particle comprising a core which comprises an oxide selected from rare earth oxides alone or in a mixture with metal oxides and which is coated with a layer of silica functionalized with a coupling agent comprising at least one chemical function soluble in a hydrophobic solvent, and to a composition comprising at least one such particle. The present invention likewise relates to the method for preparing same and to various uses thereof. | 05-05-2011 |
20120283379 | SILICA PARTICLE INCLUDING A MOLECULE OF INTEREST, METHOD FOR PREPARING SAME AND USES THEREOF - What is provided includes a nanoparticle of porous silica, incorporating at least one molecule of interest, the silica network inside said nanoparticle being functionalized by at least one group capable of setting up an ionic and/or hydrogen non-covalent bond with the molecule of interest, whereby the molecule(s) of interest is(are) linked to the silica network solely by non-covalent bonds. In addition, a method for preparing said silica particle and uses thereof is provided. | 11-08-2012 |
20140008576 | USE OF LANTHANIDE COMPLEXES FOR OPTICAL MARKING OF PRODUCTS - At least one lanthanide complex for optical marking of products, compositions for optical marking of products, and an optical marking method including an application step of these compositions. | 01-09-2014 |
