Research Topics

Researh Topics:

Atualmente, nos dedicamos ao estudo de materiais cerâmicos produzidos através do processo sol-gel. Dentro deste tópico, alguns interesses se destacam:

1) Proton conducting ceramic membranes as electrolytes in fuel cell systems:

2) Ceramic membranes for separations

3) Ceramic materials for corrosion protection and art conservation
