ICTP’s mission
• Foster the growth of advanced studies and research in physics and mathematics, especially among researchers from developing countries;
• Provide an international forum for the exchange of information and ideas among scientists from the North and South;
• Maintain excellent research facilities for visitors, associates and fellows, principally from developing countries, who participate in the Centre's research and training activities.

Key challenges for research in new materials:
Energy conversion which is:• Scalable (10 – 30 TW, in 2050)• CO2 free• Affordable
Energy storage which is:• Scalable • Affordable
"Energy engineering" knowledge:• For all
