Steenstra, E.S. (author), Klaver, M. (author), Berndt, J. (author), Flemetakis, S. (author), Rohrbach, A. (author), Klemme, S. (author)Phlogopite and K-richterite constitute important carrier phases for H and F in Earth's lithosphere and mantle. The relative importance depends on their stabilities at high pressure and temperature, which in turn depends on bulk composition. Most previous experimental studies focused on the thermal stability of phlogopite and K-richterite were...journal article 2024

Teertstra, Bouke (author)The company H2 Marine Solutions has designed a zero-emission hydrogen powered boat. This boat is compared to its fossil fuel counterpart more than twice as heavy. The reason for this is that the system components that are used in the hybrid powertrain of the hydrogen powered boat are heavier. The main question of this research is: How can we...master thesis 2023
