ELYSE founder

Dr. Belloni Jacqueline

Research director emeritus

Research interests :

  • Comparative radiolysis (pulsed and stationary) of non-aqueous polar solvents;
  • Ion adsorption by radioactive tracers;
  • Formation of stable solvated electrons by radiolysis in liquid ammonia;
  • Physical and chemical properties of solvated electrons and radical species.
  • Electron-cation recombination models as a function of the dielectric and chemical properties of the liquid;
  • Photoionization of dimethylsulfide: competition between solvation and electron attachment;
  • Transient photocurrents at the polar semiconductor-liquid interfac;
  • Metal and semiconductor aggregates : redox and optical absorption properties of the aggregates vary according to the nuclearity and are distinct from the metal or the solid semiconductor;
  • Radiolytic synthesis of mono- and multimetallic clusters, alloyed or layered, in subcolloidal solutions, supported on oxides, embedded in polymeric membranes, zeolites or mesoporous solids;
  • Molecular clusters of carbonyl metals synthesized by irradiation.
  • Mechanisms of nucleation, growth, and development by combination of radiolysis with chemical reductions,
  • Mechanism of photographic development: applications to catalysis, non-linear optics, photography.
  • Latent image formation in silver photography.
  • Electron-hole recombination in silver halides;
  • Role of nuclearity dependent properties in aggregate nucleation and thermal hysteresis at phase transition.
