Discovery of a low-density filled-ice phase in nitrogen hydrate at high pressure
Selene Berni, Sophie Espert, Tomasz Poreba +7
We map the high-pressure phase diagram of nitrogen hydrate up to 16 GPa at room temperature by combining neutron diffraction, Raman spectroscopy, and crystal structure prediction.…

Hydrogen bond symmetrization in high-pressure ice clathrates
Lorenzo Monacelli, Maria Rescigno, Alasdair Nicholls +3
Hydrogen bond symmetrization is a fundamental pressure-induced transformation in which the distinction between donor and acceptor sites vanishes, resulting in a symmetric hydrogen-…
