Hydrogen Hydrates Under Extreme Conditions: Insights Into High-pressure Phases and Implications for Planetary Interiors

Richard Gaal, Livia Eleonora Bove Kado, Tomasz Poreba

Hydrogen hydrates, formed from hydrogen and water under high-pressure and low-temperature conditions, exhibit a rich phase behavior governed by intricate intermolecular interactions. Their structural evolution under extreme conditions provides a unique pla ...

Transport Properties of Supercritical Methane

Livia Eleonora Bove Kado

The experimental results on molecular diffusion in supercritical methane in a wide pressure range reported by [U. Ranieri et al., Nat. Commun. 15, 4142 (2024)] are compared with the theoretical expectations based on the Lennard-Jones model. In the low-pres ...

Observation of plastic ice VII by quasi-elastic neutron scattering

Richard Gaal, Livia Eleonora Bove Kado, Maria Rescigno

Water is the third most abundant molecule in the universe and a key component in the interiors of icy moons, giant planets and Uranus- and Neptune-like exoplanets1, 2–3. Owing to its distinct molecular structure and flexible hydrogen bonds that readily ada ...

Large-cage occupation and quantum dynamics of hydrogen molecules in sII clathrate hydrates

Richard Gaal, Livia Eleonora Bove Kado, Umbertoluca Ranieri

Hydrogen clathrate hydrates are ice-like crystalline substances in which hydrogen molecules are trapped inside polyhedral cages formed by the water molecules. Small cages can host only a single H-2 molecule, while each large cage can be occupied by up to f ...

Crossover from gas-like to liquid-like molecular diffusion in a simple supercritical fluid

Livia Eleonora Bove Kado

According to textbooks, no physical observable can be discerned allowing to distinguish a liquid from a gas beyond the critical point. Yet, several proposals have been put forward challenging this view and various transition boundaries between a gas-like a ...

Observation of the most H2-dense filled ice under high pressure

Richard Gaal, Livia Eleonora Bove Kado, Lorenzo Monacelli, Maria Rescigno

Hydrogen hydrates are among the basic constituents of our solar system's outer planets, some of their moons, as well Neptune-like exo-planets. The details of their high-pressure phases and their thermodynamic conditions of formation and stability are funda ...

Observation of a Plastic Crystal in Water-Ammonia Mixtures under High Pressure and Temperature

Livia Eleonora Bove Kado

Solid mixtures of ammonia and water, the so-called ammonia hydrates, are thought to be major components of solar and extra-solar icy planets. We present here a thorough characterization of the recently reported high pressure (P)-temperature (T) phase VII o ...

Low-Temperature Dynamics of Water Confined in Unidirectional Hydrophilic Zeolite Nanopores

Livia Eleonora Bove Kado, Umbertoluca Ranieri, Maria Rescigno

The dynamical properties of water molecules confinedin the unidirectionalhydrophilic nanopores of AlPO4-54 are investigated withquasi-elastic neutron scattering as a function of temperature downto 118 K. AlPO4-54 has among the largest pores known foralumin ...

Temperature- and pressure-dependence of the hydrogen bond network in plastic ice VII

Livia Eleonora Bove Kado, Umbertoluca Ranieri, Maria Rescigno

We model, via classical molecular dynamics simulations, the plastic phase of ice VII across a wide range of the phase diagram of interest for planetary investigations. Although structural and dynamical properties of plastic ice VII are mostly independent o ...

Observation of methane filled hexagonal ice stable up to 150 GPa

Richard Gaal, Philippe Gillet, Livia Eleonora Bove Kado, Umbertoluca Ranieri

Gas hydrates consist of hydrogen-bonded water frameworks enclosing guest gas molecules and have been the focus of intense research for almost 40 y, both for their fundamental role in the understanding of hydrophobic interactions and for gas storage and ene ...

Quantum Dynamics of H-2 and D-2 Confined in Hydrate Structures as a Function of Pressure and Temperature

Richard Gaal, Philippe Gillet, Livia Eleonora Bove Kado, Umbertoluca Ranieri

We present an extensive study of the quantum dynamics of molecular hydrogen trapped within the nanocavities of two hydrate structures at low temperatures, namely, clathrate structure II and filled ice structure Cl. By inelastic neutron scattering measureme ...

Salt- and gas-filled ices under planetary conditions

Livia Eleonora Bove Kado, Umbertoluca Ranieri

In recent years, evidence has emerged that solid water can contain substantial amounts of guest species, such as small gas molecules-in gas hydrate structures-or ions-in salty ice structures-and that these 'filled' ice structures can be stable under pressu ...

Ice VII from aqueous salt solutions: From a glass to a crystal with broken H-bonds

Livia Eleonora Bove Kado

It has been known for decades that certain aqueous salt solutions of LiCl and LiBr readily form glasses when cooled to below approximate to 160 K. This fact has recently been exploited to produce a "salty" high-pressure ice form: When the glass is compress ...

X‑ray and Neutron Scattering of Water

Quantum versus classical protons in pure and salty ice under pressure

Richard Gaal, Livia Eleonora Bove Kado

It is generally accepted that nuclear quantum effects (NQEs) trigger the transition to the nonmolecular form of ice under increasing pressure. This picture is challenged in salty ice, where Raman scattering measurements up to 130 GPa of molecular ice VII c ...
