A method for preparing coated metal nanoparticles, each nanoparticle comprising a core constituted of at least one metal M and a layer constituted of at least one polymer, the layer coating the metal core. The method comprises the steps: (a) preparing a solution A comprising the at least one metal M in the form of cations M, n being an integer comprised between 1 and 3, each metal M being a transition metal of atomic number comprised between 21 and 30, a polyol, and a noble metal salt; (a) preparing a solution B comprising at least one organic monomer of the at least one polymer, in an organic solvent; (b) mixing solutions A and B, this mixture being heated to the boiling temperature of the polyol; and (c) recovering the coated metal nanoparticles.

A method for producing a conductive area in a polymer material comprises: providing a polymer layer comprising conductive particles with a density such that the polymer layer is insulating, heating the polymer material to a temperature higher than or equal to the glass transition temperature of the polymer material, compressing a portion of the polymer layer using a stamp, in order to obtain a density of conductive particles such that the portion becomes conductive, and removing the stamp from the polymer layer.

Polymer locally comprising conductive areas

The invention relates to a method for displacing an object in a solid system involving the following steps: placing the object in a matrix which is solid at a first temperature and capable of softening due to the effect of a temperature increase; if necessary, increasing the temperature until the matrix softens; applying an external action to the object so as to move it inside the matrix; lowering the temperature until the matrix solidifies.

Producing a deformable system with a view to displacing an object enclosed in the latter

A method for making an electric interconnection between two conducting layers, separated by at least one insulation or semi-conducting layer, which includes forming a stud extending between at least the lower conducting layer and the upper conducting layer, where the nature and/or the shape of the stud impart non-wettability properties relative to the material used for the separating layer.

The method of coating the area of hybridization of a component that is constituted by two elements bonded to one another by means of a soldering material, including depositing proximate to the component a coating substance capable of filling by capillarity action the volume defined between the hybridized elements of the component. Further, along the periphery of the hybridization area on the lower element of the component is an area of non-wettability in regards to the coating substance, that is defined by depositing an anti-wetting covering of PECVD in regards to the coating substance, whereby the anti-wetting covering on the first element encompasses the hybridization area and surrounds a wetting surface for the coating substance.
