The LCMC is an association of research groups  from University of Pierre et Marie Curie (UFR 926 directed by Prof. M. Brigodiot) and the "Inorganic Materials" group (UMR 7574) of the National Center of Scientific Research (CNRS) directed by Prof. J. Livage

The laboratory has a long story of outstanding contributions to the basic understandings of transition elements precursors reactivities and in general  "Soft Chemistry" routes to materials. This includes Sol-Gel methods from alkoxides precursors and synthesis routes in aqueous media (precipitation, co-precipitation and hydrothermal processing). Of particular interest is the synthesis and understanding of nanoparticles of metal oxides elaborated through careful control of the solid-liquid interface. The lab expertise and previous knowledge on precursors chemistry facilitate the set up of research protocols leading to structural morphological and dimensional control of synthesized nanoparticles. In the last years a significant effort was devoted to synthesize and characterize of functional oxo-clusters  These oxo-clusters are not only excellent spectroscopic references but also  potential building blocs of a variety of nanomaterials  and more complex and original hybrids architectures. 

The laboratory make uses of a great variety of experimental techniques to establish fundamental knowledge needed for the realization of  "à la carte" materials through soft chemistry. Among the techniques available in the lab: 

  • Multinuclear NMR of liquids and solids
  • X-rays diffraction
  • Mössbauer Spectroscopy
  • Light Scattering
  • Electrical conductivity measurements
  • FTIR spectroscopy
  • Scanning Electron Microscopy
  • Transmission electron Microscopy
  • Raman Scattering
  • Adsorption - desorption and specific surface area measurements 
  • Thermal analysis (DTA, TGA, DSC)
  • EPR

The lab has also access to shared big facilities : EXAFS, XANES, DPAX

The group in the last five years has generated more than 300  papers and 35 PhD thesis.
