Crystallization of pristine cubic ice from liquid at ambient pressure
Chenwei Zheng, Paul F. Henry, Aasim I. Shaffi +11
The phase diagram of frozen water is famously rich: to date, over twenty crystalline polymorphs have been identified. Of the low-pressure 'ice I' family, hexagonal (Ih) is the prin…
Deep-glassy ice VI confirmed with a combination of neutron spectroscopy and diffraction
Alexander Rosu-Finsen, Alfred Amon, Jeff Armstrong +2
The recent discovery of a low-temperature endotherm upon heating hydrochloric-acid doped ice VI has sparked a vivid controversy. The two competing explanations aiming to explain it…
Ammonium Fluoride as a Hydrogen-disordering Agent for Ice
Christoph G. Salzmann, Zainab Sharif, Craig L. Bull +3
The removal of residual hydrogen disorder from various phases of ice with acid or base dopants at low temperatures has been a focus of intense research for many decades. As an anti…
Advances in the experimental exploration of water's phase diagram
Christoph G. Salzmann
Water's phase diagram displays enormous complexity with currently 17 experimentally-confirmed polymorphs of ice and several more predicted computationally. For almost 120 years, it…
Benchmarking acid and base dopants with respect to enabling the ice V to XIII and ice VI to XV hydrogen-ordering phase transitions
Alexander Rosu-Finsen, Christoph G. Salzmann
Doping the hydrogen-disordered phases of ice V, VI and XII with hydrochloric acid (HCl) has led to the discovery of their hydrogen-ordered counterparts ices XIII, XV and XIV. Yet,…
Double-layer ice from first principles
Ji Chen, Georg Schusteritsch, Chris J. Pickard +2
The formation of monolayer and multilayer ice with a square lattice structure has recently been reported on the basis of transmission electron microscopy experiments, renewing inte…
Is High-density Amorphous Ice Simply a 'Derailed' State along the Ice I to Ice IV Pathway?
Jacob J. Shephard, Sanliang Ling, Gabriele C. Sosso +3
The structural nature of high-density amorphous ice (HDA), which forms through low-temperature pressure-induced amorphization of the 'ordinary' ice I, is heavily debated. Clarifyin…
Detailed crystallographic analysis of the ice VI to ice XV hydrogen ordering phase transition
Christoph G. Salzmann, Ben Slater, Paolo G. Radaelli +4
The D2O ice VI to ice XV hydrogen ordering phase transition at ambient pressure is investigated in detail with neutron diffraction. The lattice constants are found to be sensitive…
A new structural relaxation pathway of low-density amorphous ice
Jacob J. Shephard, Stefan Klotz, Martin Vickers +1
Low-density amorphous ice (LDA) is involved in critical cosmological processes and has gained prominence as one of the at least two distinct amorphous forms of ice. Despite these a…
2D ice from first principles: structures and phase transitions
Ji Chen, Georg Schusteritsch, Chris J. Pickard +2
Despite relevance to disparate areas such as cloud microphysics and tribology, major gaps in the understanding of the structures and phase transitions of low-dimensional water ice…
The complex kinetics of the ice VI to ice XV hydrogen ordering phase transition
Jacob J. Shephard, Christoph G. Salzmann
The reversible phase transition from hydrochloric-acid-doped ice VI to its hydrogen-ordered counterpart ice XV is followed using differential scanning calorimetry. Upon cooling at…
Extent of stacking disorder in diamond
Christoph G. Salzmann, Benjamin J. Murray, Jacob J. Shephard
Hexagonal diamond has been predicted computationally to display extraordinary physical properties including a hardness that exceeds cubic diamond. However, a recent electron micros…
Edge-carboxylated Carbon Nanoflakes from Nitric Acid Oxidised Arc-discharge Material
Christoph G. Salzmann, Valeria Nicolosi, Malcolm L. H. Green
Carbon Nanoflakes (CNFs) with average diameters of about 30 nm have been prepared and isolated in bulk quantities by a single-step oxidation procedure using single-wall carbon nano…
Ice XV: a new thermodynamically stable phase of ice
Christoph G. Salzmann, Paolo G. Radaelli, Erwin Mayer +1
A new phase of ice, named ice XV, has been identified and its structure determined by neutron diffraction. Ice XV is the hydrogen-ordered counterpart of ice VI and is thermodynamic…
