Abstract: Solution for use in filling micrometer-size cavities (10), the solution comprising a first solvent, a first polymer (102) having a first molecular weight, a second polymer (103) having a second molecular weight, luminophores (101) and a surfactant, the second molecular weight being 10 to 50 times greater than the first molecular weight.

Abstract: The invention relates to a device for cooling an organ locally, that includes an elongate stem including a far end intended to make contact with an organ to be cooled and comprising including a cooling element having a cold finger, a crystal that has a capacity to cool via excitation at a set excitation wavelength, said crystal being positioned adjacent to said cooling element, an optical guide that is able to convey a light signal at said excitation wavelength and that opens onto said crystal, and an illuminating system including at least one light source, which light source is arranged to emit said light signal.

Abstract: A device for measuring an amount of beryllium in a radioactive object, including: a hollow cylinder of a first piece made of a material to thermalize neutrons emitted by the radioactive object and a metal piece to mitigate a dose rate on the radioactive object, the first piece having a hollow cylinder shape deprived of a wall fraction, the metal piece including a solid part inserted in a space which corresponds to the deprived wall fraction of the first piece and a recessed part which is an extension of the solid part and is accommodated within the wall of the first piece, in contact with the first piece; a gamma radiation source accommodated in an indentation of the recessed part of the metal piece; and at least one neutron detector placed in a bulk of the first piece.
