EFree focuses on developments in the following four thrust areas and associated strategies:
1. Novel superconducting, electronics, and magnetic materials under extreme P-T
2. Novel hydrogen and hydrogen-bearing systems under extreme P-T
3. Novel light-element and covalent materials under extreme P-T
4. Novel nanophase, composite, amorphous and geological materials under extreme P-T

The subcontract is awarded for five year starting from 2009.
