20080199126 | Method for Printing a Near Field Photoinduced Stable Structure, and Optical Fiber Tip for Implementing Same - The method comprises emitting appropriate polarisation light waves on a photosensitive material for inducing therein a topographic modification through an aperture of at the most 100 mm bound by an opaque area, said layer being arranged at the most 100 mm away from the aperture. | 08-21-2008 |
20090324968 | COMPOSITION FOR HYDROPHOBIC TREATMENT AND GLAZING - Hydrophobic treatment composition comprising one or more compounds, as a mixture, corresponding to the formula | 12-31-2009 |
20110114886 | RARE-EARTH PHOSPHATE COLLOIDAL DISPERSION, METHOD FOR THE PRODUCTION THEREOF AND A TRANSPARENT LUMINESCENT MATERIAL OBTAINABLE FROM SAID DISPERSION - The invention relates to a colloidal dispersion comprising rhabdophane-structured rare-earth phosphate particles (Ln) and a polyphosphate. Said dispersion is prepared by a method consisting in forming a medium comprising at least one type of rare-earth salt and a poly phosphate in such quantities that the P/Ln ratio is equal to or higher than 3, in heating the thus obtained medium and in removing residual salts, thereby obtaining said dispersion. Said invention also relates to a transparent luminescent material which is obtainable from said dispersion and based on the rare-earth phosphate particles and a polyphosphate and whose P/Ln ratio is higher than 1, to a luminescent system comprising said material and to an excitation source. | 05-19-2011 |

20110305827 | Methods of Using a Non-Photocatalytic Porous Coating as an Antisoiling Coating - The present invention relates to the use as an antisoiling coating of a porous coating comprising a polysiloxane matrix and a porous volume such that the potential filling ratio of the total volume of said coating by oleic acid is at least 25% by volume, having a porosity rate ranging from 25 to 70% by volume and having no photocatalytic properties. The antisoiling porous coating is self-cleaning, easy to clean and can be regenerated by simple washing. It is mainly intended for use in ophthalmic optics, and proves to be very effective against sebum. In the preferred embodiment of the invention, this coating has a mesoporous structure. | 12-15-2011 |

20130078458 | METHOD FOR THE LOW-TEMPERATURE PREPARATION OF ELECTRICALLY CONDUCTIVE MESOSTRUCTURED COATINGS - The present invention relates to a method for manufacturing mesostructural coatings comprising electrically conductive structures formed of metal nanoparticles. Said method includes the steps that involve: a) depositing on a substrate, a first layer consisting of a silica material, mesostructured by a structuring agent, and a photocatalytic material: b) depositing on the first layer, a second layer of a mesostructural silica material, said second layer being free of photocatalytic material: c) consolidating the first and second layers at at temperature between 50° C. and 250° C.; and d) placing the consolidating coating in contact with a solution that contains and irradiatting coating with a radiation that enables the photocatalytic material to be activated. Said method is characterized in that it includes no heat treatment at a temperature greater than 250° C. | 03-28-2013 |
