Sandra Ninet

Présentation

Résumé : Mes activités de recherche sont centrées sur la détermination expérimentale des propriétés structurales et vibrationnelles des constituants les plus simples de l’Univers (H2O, NH3, CO2, He, N2, H2…) sous conditions extrêmes de pression (1-300 GPa) et de température (20-5000 K). Les applications sont pluridisciplinaires : physique fondamentale, sciences planétaires et science des matériaux.

Mots-clés : systèmes moléculaires, glaces, liaison hydrogène, conditions extrêmes de pression et de température, propriétés structurales et vibrationnelles

Techniques expérimentales : dispositifs haute pression, diffraction des rayons X/des neutrons, spectroscopies (Raman, infrarouge, Brillouin), chauffage laser en cellule à enclumes de diamant
