摘要:
Current collector for electrochemical devices comprising a metal support in contact with an electrolyte containing a bistriflimide anion, hereafter named as TFSI - , characterized in that said metal support comprises an electro-active surface which is functionalized with linear or branched fluorinated carbon chains, such as a perfluoroalkyl chains, in the form of a molecular layer which improves the corrosion resistance of said functionalized surface compared to a non-functionalized surface. The invention also relates to the use of said current collector in a storage energy device, such as a lithium-ion, sodium-ion, aluminum-ion, calcium-ion or magnesium-ion battery, in a supercapacitor, in a photo-battery, or in an electro-chromic device, and to the process of functionalizing the active surface of the current collector.
摘要:
The present invention relates to a compound with formula (I) or a salt and/or a pharmaceutically acceptable solvate thereof, the method for preparing same as well as the uses thereof, in particular the therapeutic use thereof, mainly in the treatment of diseases associated with a hyperactivity of the endocannabinoid system.
摘要:
The invention relates to a system for assessing chloride concentration at one predetermined area of a porous or composite material, such as a reinforced concrete structure, comprising a sensor (1) embedded in the predetermined area of the material, an analyser (2) connected to the sensor, and a processing module (4) connected to the analyser. The sensor (1) comprises two facing or coplanar electrodes (11), called electrodes, an intermediate layer (13) arranged between said electrodes, said intermediate layer being in contact with the material of the first area of the structure and comprising calcium aluminates. The analyser (2) is configured to apply an alternate current between the electrodes and output an impedance value or capacitance value of the intermediate layer. The processing module (4) is configured to compute a chloride concentration assessment in the predetermined area of the material based on the impedance value or capacitance value outputted by the analyser.

摘要:
The invention relates to a method and to a device for displaying a three-dimensional scene on a display surface having an arbitrary non-planar shape, for correct viewing by a user having a given position in a three-dimensional spatial reference system. The method comprises displaying a display image comprising pixels which represent the three-dimensional scene. The invention comprises: a first step (A1) of projecting a three-dimensional model of the display surface onto a projection plane (P L ) in perspective, the projection in perspective having a projection centre which is dependent on the position of the user in the spatial reference system, making it possible to obtain a projection image (I proj ) of the display surface from the point of view of the user; and a second step (A2) of calculating a projection of the three-dimensional scene on the display surface using said projection image (I proj ).
