The Matter at High Pressure (MALTA) initiative has born to address frontier questions related to high pressure research and technology.

At the present birth stage of MALTA, we shall mainly focus our efforts on materials involving nitrogen, oxygen, carbon and hydrogen (NOCH materials on the following). Far from being a limitation, this choice will allow us to systematise the study of a number of interrelated phenomena from different scientific fields through a careful selection of a few families of NOCH compounds. This choice will allow us to address in a unified way seven mayor challenges such as: 1) High pressure phases of molecular solids, 2) Minerals and life-related processes, 3) Abiotic origin of organic compounds in extreme conditions, 4) Water and hydration in extreme conditions, 5) Life in extreme conditions, 6) Hydrogen and Hydrogen storage, and 7) Earth and Planetary Materials.

The complexity and diversity of high pressure phenomena related to Materials, Earth and Life Sciences require the integration of both theoretical and experimental approaches. Hence there is not only a reliance on the fundamental methodologies of physics and chemistry, but also a significant overlap with geology and biology, as depicted in the diagram inserted on the right. Thus, the key scientific questions of MALTA will be addressed by several interconnected research fields.
