Hydrophobic hydration of the hydrocarbon adamantane in amorphous ice.

Hydrophobic molecules are by definition difficult to hydrate. Previous studies in the area of hydrophobic hydration have therefore often relied on using amphiphilic molecules where the hydrophilic part of a molecule enabled the solubility in liquid water. Here, we show that the hydrophobic adamantane (CH) molecule can be fully hydrated through vapour codeposition with water onto a cryogenic substrate at 80 K resulting in the matrix isolation of adamantane in amorphous ice.

Medium-density amorphous ice.

Amorphous ices govern a range of cosmological processes and are potentially key materials for explaining the anomalies of liquid water. A substantial density gap between low-density and high-density amorphous ice with liquid water in the middle is a cornerstone of our current understanding of water. However, we show that ball milling "ordinary" ice I at low temperature gives a structurally distinct medium-density amorphous ice (MDA) within this density gap.

Structure and nature of ice XIX.

Ice is a material of fundamental importance for a wide range of scientific disciplines including physics, chemistry, and biology, as well as space and materials science. A well-known feature of its phase diagram is that high-temperature phases of ice with orientational disorder of the hydrogen-bonded water molecules undergo phase transitions to their ordered counterparts upon cooling. Here, we present an example where this trend is broken.

Preparation and Structure of the Ion-Conducting Mixed Molecular Glass GaI.

Modern functional glasses have been prepared from a wide range of precursors, combining the benefits of their isotropic disordered structures with the innate functional behavior of their atomic or molecular building blocks. The enhanced ionic conductivity of glasses compared to their crystalline counterparts has attracted considerable interest for their use in solid-state batteries. In this study, we have prepared the mixed molecular glass GaI and investigated the correlations between the local structure, thermal properties, and ionic conductivity.

Detailed crystallographic analysis of the ice V to ice XIII hydrogen-ordering phase transition.

Ice V is a structurally highly complex material with 28 water molecules in its monoclinic unit cell. It is classified as a hydrogen-disordered phase of ice. Yet, some of its hydrogen-bonded water molecules display significant orientational order.

The crystallography of Pluto.

Maynard-Casely and co-workers [ (2020). , 844-851.] investigate two of Pluto's most abundant minerals with neutron diffraction.

Amorphous Mixtures of Ice and C Fullerene.

Carbon and ice make up a substantial proportion of our universe. Recent space exploration has shown that these two chemical species often coexist such as on comets and asteroids and in the interstellar medium. Here, we prepare mixtures of C fullerene and HO by vapor codeposition at 90 K with molar C/HO ratios ranging from 1:1254 to 1:5.
