The invention relates to a process for producing a membrane filter comprising the steps of selecting a honeycomb monolith with a network of channels separated by porous channel walls and the deposition on these walls of a membrane that adheres to the wall, obtained by a coating operation during which some of the walls of the monolith are placed in contact with an aqueous suspension of a sinterable powder of a constituent material of the monolith then by drying and finally by calcining the coated monolith. The membrane is obtained by repeating the coating operation, the weight concentration of sinterable powder in the aqueous suspension being reduced at each new operation, and the calcination is carried out at a temperature below 1000C.


Pixel comprising three adjacent sub-pixels (P1, P2, P3), formed by respective stacks of semiconducting layers, said pixel being characterized in that: - each said sub-pixel comprises a first active layer (32), adapted to emit a light at a first wavelength (1) when it is traversed by an electric current; - another sub-pixel (P2) also comprises a second active layer (52, 52), adapted to emit a light at a second wavelength (2) greater than said first wavelength; - another of said sub-pixels (P3) also comprises a third active layer (22, 6), adapted to emit a light at a third wavelength (3) greater than said first wavelength and different from said second wavelength; at least one out of said second and third active layer being adapted to emit said light when it is excited by the light of the first wavelength emitted by said first active layer of the same sub-pixel. Semi-conducting structure and methods for the fabrication of such a pixel.

SYRAL Belgium NV and French National Center for Scientific Research | Date: 2017-04-19

The invention relates to a composition of isomers of mono-alkyl ethers of monoanhydro-hexitol having an alkyl ether radical (OR) at C-3, C-5 or C-6 of the monoanhydro-hexitol, in which the alkyl group (R) is a linear or branched, cyclic or non-cyclic hydrocarbon group comprising between 4 and 18 carbon atoms. The invention also relates to the method for producing such a composition, as well as to the use thereof as a non-ionic surfactant, an emulsifier, a lubricant, an antimicrobial agent or a dispersing agent.

The present invention relates to a method for predicting the survival time of a patient suffering from acute myeloid leukemia (AML) comprising i) determining in a sample obtained from the patient the expression level of NKp46 ii) comparing the expression level determined at step i) with its predetermined reference value and iii) providing a good prognosis when the expression level determined at step i) is higher than its predetermined reference value, or providing a bad prognosis when the expression level determined at step i) is lower than its predetermined reference value.


Patent
Aria Energie Developpement Environnement, French National Institute for Agricultural Research and French National Center for Scientific Research | Date: 2017-01-18

The invention relates to a device for separating a first gas component and a second gas component which are contained in a gas mixture, comprising: a liquid/gas absorption separation column (10), comprising a lower tank (12) and an upper separation area (11); means for placing the gas mixture in contact, with a liquid solution capable of selectively absorbing the second gas component, via counter-flow circulation in the separation area (11); and means (19) for recovering the first gas component, separate from the second gas component. The tank (12) stores a volume (16) of absorbing solution. The transverse cross-sectional surface of the tank (12) of the absorption column (10) is no lower than twice the transverse cross-sectional surface of the separation area (11) of the absorption column (10).
