Thèmes de recherche

L'objectif principal de l'équipe est l'élaboration de nano matériaux fonctionnels, capables d’interagir avec leur environnement ; matériaux pour la détection de gaz, de rayonnements, dégradation de polluants, conversion et stockage d'énergie. L'équipe s'intéresse plus particulièrement :

-à la compréhension des mécanismes de formation et croissance de nanomatériaux, et des processus de mise en forme

-aux relations micro-nanostructure /propriétés/réactivité : propriétés en relation avec la réactivité des matériaux à leur environnement (gaz, liquide, rayonnement), catalyse, transports électronique et ionique, transport thermique, luminescence, photocatalyse.

Auto organisation de nanocristaux de SrWO4 .
Les cinétiques de photo-dégradation de colorants dans l'eau sont différentes suivant les types d'auto-organisation (fleurs, navettes, sphères).

Nanooctaèdre de Co_1.5Fe_1.5O₄, qui présente uniquement des faces {111} au gaz. L'obtention de nanocristaux de forme spécifique permet l'étude de la réactivité de faces cristallographiques en présence de gaz.

Nanooctaèdre

Imagerie Hyperspectrale d'une valve de diatomée

Imagerie Hyperspectrale 4D (x,y,z,w) d'une valve de diatomée.

La structure multi-échelle des diatomées leur confère une efficacité remarquable pour le piégeage de la lumière en associant des propriétés de type guide d'onde et cristal photonique.
