Programma esteso
PYROCHLORES as prototypes of materials with a wide variety of technologically important functional properties. They have the ability to incorporate REE and possess fluorescence and phosphorescence properties with potential optical applications, the presence of defects and vacations can change its conductivity, may be materials capable of incorporating nuclear waste actinides, and have interesting dielectric properties
GARNET is an important material for technical issues, e.g. the well-known yttrium aluminium garnet (YAG)-Laser, and now finds new applications, e.g. in the field of energy storage. Although the chemical composition varies considerably all garnets have the same crystal structure in common. For example, lithium oxide garnet has recently been identified as a promising material in the field of energy storage, (e.g. in lithium-ion batteries)
PEROVSKITES are characterized by a structure that when changing the chemical composition change physical properties such as ferroelectricity, magnetic properties, themoelectric property making them suitable for energy conversion applications.
SPINEL. Synthetic analogues of spinel are used in the fields of photovoltaic, piezoelectric, catalysis, batteries and thermoelectric
NANOSTRUCTURED MATERIALS. nanostructured catalytic materials based on metallic oxides (Fe, Ni, Al, Zn, Ti) for energy storage, magnetic nanostructured materials from microbial reduction of iron minerals.
Acid mine drainage (AMD) origin, prevention and remediation
BIOMINERALIZATION for environmental remediation and as resource.
