  • 1,8-naphthalimide derivatives as scintillation agents, in particular for discriminating between fast neutrons and gamma rays
    Patent number: 8894881
    Abstract: The invention relates to the use of 1,8-naphthalimide derivatives and of their salts as scintillation agents and more specifically as agents for discriminating between fast neutrons and gamma rays. It also relates to liquid scintillators comprising these scintillation agents in solution in a solvent and to novel 1,8-naphthalimide derivates of use as scintillation agents, in particular for discriminating between fast neutrons and gamma rays. Applications: all the fields of use of scintillators and in particular industry, geophysics, fundamental physics, in particular nuclear physics, the safety of goods and people, protection from radiation of workers in the industrial, nuclear and medical sectors, medical imaging, and the like.

  • Highly-selective tandem chemical sensor and detection method using same
    Publication number: 20070148696
    Abstract: The invention relates to a chemical sensor intended for the detection of a type of molecule comprising a fluorescent material capable of forming a charge transfer complex with the type of molecule to be detected and means for measuring the variation in fluorescence of said material, characterized in that it additionally comprises a filter comprising a polymer material comprising “molecularly imprinted” cavities, the geometric and chemical configuration of which is defined so as to fix the type of molecule to be detected. The invention also relates to a detection method using the sensor according to the invention.
