Patent number: 10668501Abstract: The present invention relates to a process for texturing surfaces providing the latter with superhydrophobic, superoleophobic, superhydrophilic or even superoleophilic properties. This process comprises i) a step of texturing the surface (via the deposition of nanoparticles of different sizes); ii) a step of curing the surface thus textured (with a curing agent); and, optionally, iii) a step of modifying the properties of the surface with perfluorinated (and therefore hydrophobic) molecules. This process is suitable, inter alia, for treating transparent and/or heat-sensitive materials and surfaces. Specifically, none of the steps of the process use a temperature higher than 100° C. Thus, the process of the invention is particularly suitable for treating transparent surfaces composed of non-mineral materials, such as polycarbonate for example, as it will affect neither their transparency nor their optical properties.Type: GrantFiled: May 20, 2015Date of Patent: June 2, 2020Assignees: Centre National de la Recherche Scientifique (CNRS), Surfactis TechnologiesInventors: David Portet, Nicolas Lefevre, Stéphane Bejanin, Abdelhafed Taleb, Dorra Ben Jazia Dallel, Olivier Favrat

Patent number: 10557039Abstract: A liquid composition comprising at least one bisphosphonic compound bearing at least one partially fluorinated, perfluorinated (PF) or perfluorpolether (PFPE) group. The bisphosphonic compound is dissolved in at least one non-flammable fluorinated solvent or in a mixture of non-flammable fluorinated solvents. A method for increasing the lipophobic or hydrophobic properties of a surface is also disclosed, wherein a liquid composition comprising at least one bisphosphonic compound bearing at least one partially fluorinated, perfluorinated (PF) or perfluorpolether (PFPE) group is applied to the surface. The method may include preliminary oxidation of the surface, if necessary; contacting the surface with the liquid composition until the bisphosphonic compound contained therein is assembled in a layer coating the surface; and drying the surface thus coated.Type: GrantFiled: February 21, 2017Date of Patent: February 11, 2020Assignee: Surfactis TechnologiesInventors: Stéphane Bejanin, David Portet

Patent number: 7223727Abstract: The present invention relates to the field of metabolic research. Metabolic disorders, such as obesity, are a public health problem that is serious and widespread. GSSP4 polypeptides have been identified that are believed to be beneficial in the treatment of metabolic disorders. These compounds should be effective for reducing cholesterol levels, body mass, body fat, and for treating metabolic-related diseases and disorders. The metabolic-related diseases or disorders include, but are not limited to, obesity, hyperlipidemia, hypercholesterolemia, atherosclerosis, diabetes, glucose intolerance, insulin resistance and hypertension.Type: GrantFiled: February 7, 2002Date of Patent: May 29, 2007Assignee: Serono Genetics Institute S.A.Inventors: Barbara Chicca, John Chicca, Blake Denison, Frances Yen-Potin, Bernard Bihain, Stephane Bejanin, Hiroaki Tanaka, Severin Jobert, Jean-Yves Giordano, Jean-Baptiste Dumas Milne Edwards
