Liquid-like relaxation in hyperquenched water at < or = 140 K.

Physical chemistry chemical physics : PCCP

Kohl I, Bachmann L, Hallbrucker A, Mayer E, Loerting T.
PMID: 16240034
Phys Chem Chem Phys. 2005 Sep 07;7(17):3210-20. doi: 10.1039/b507651j. Epub 2005 Aug 01.

Micrometre-sized water droplets were hyperquenched on a solid substrate held at selected temperatures between 150 and 77 K. These samples were characterized by differential scanning calorimetry (DSC) and X-ray diffraction. 140 K is the upper temperature limit to obtain...

Structure of a new dense amorphous ice.

Physical review letters

Finney JL, Bowron DT, Soper AK, Loerting T, Mayer E, Hallbrucker A.
PMID: 12443486
Phys Rev Lett. 2002 Nov 11;89(20):205503. doi: 10.1103/PhysRevLett.89.205503. Epub 2002 Oct 29.

The detailed structure of a new dense amorphous ice, VHDA, is determined by isotope substitution neutron diffraction. Its structure is characterized by a doubled occupancy of the stabilizing interstitial location that was found in high density amorphous ice, HDA....

Water Behaviour: glass transition in hyperquenched water?.

Nature

Kohl I, Bachmann L, Mayer E, Hallbrucker A, Loerting T.
PMID: 15917753
Nature. 2005 May 26;435(7041):E1; discussion E1-2. doi: 10.1038/nature03707.

It has been unclear whether amorphous glassy water heated to around 140-150 K remains glassy until it crystallizes or whether instead it turns into a supercooled and very viscous liquid. Yue and Angell compare the behaviour of glassy water...

Carbonic acid in the gas phase and its astrophysical relevance .

Science (New York, N.Y.)

Science. 1998 Feb 27;279(5355):1332-5. doi: 10.1126/science.279.5355.1332.

In outer space, high-energy irradiation of cryogenic ice mixtures of abundant water and carbon dioxide is expected to form solid carbonic acid. Experiments and thermodynamic analyses show that crystalline carbonic acid sublimates without decomposition. Free-energy considerations based on highly...

Structures of high and low density amorphous ice by neutron diffraction.

Physical review letters

Finney JL, Hallbrucker A, Kohl I, Soper AK, Bowron DT.
PMID: 12059427
Phys Rev Lett. 2002 Jun 03;88(22):225503. doi: 10.1103/PhysRevLett.88.225503. Epub 2002 May 17.

Neutron diffraction with isotope substitution is used to determine the structures of high (HDA) and low (LDA) density amorphous ice. Both "phases" are fully hydrogen bonded, tetrahedral networks, with local order similarities between LDA and ice Ih, and HDA...

About the stability of sulfurous acid (H2SO3) and its dimer.

Chemistry (Weinheim an der Bergstrasse, Germany)

Voegele AF, Tautermann CS, Loerting T, Hallbrucker A, Mayer E, Liedl KR.
PMID: 12693045
Chemistry. 2002 Dec 16;8(24):5644-51. doi: 10.1002/1521-3765(20021216)8:24<5644::AID-CHEM5644>3.0.CO;2-9.

The characterization and isolation of sulfurous acid (H2SO3) have never been accomplished and thus still remain one of the greatest open challenges of inorganic chemistry. It is known that H2SO3 is thermodynamically unstable. In this study, however, we show...

The preparation and structures of hydrogen ordered phases of ice.

Science (New York, N.Y.)

Salzmann CG, Radaelli PG, Hallbrucker A, Mayer E, Finney JL.
PMID: 16556840
Science. 2006 Mar 24;311(5768):1758-61. doi: 10.1126/science.1123896.

Two hydrogen ordered phases of ice were prepared by cooling the hydrogen disordered ices V and XII under pressure. Previous attempts to unlock the geometrical frustration in hydrogen-bonded structures have focused on doping with potassium hydroxide and have had...

The local and intermediate range structures of the five amorphous ices at 80 K and ambient pressure: a Faber-Ziman and Bhatia-Thornton analysis.

The Journal of chemical physics

Bowron DT, Finney JL, Hallbrucker A, Kohl I, Loerting T, Mayer E, Soper AK.
PMID: 17129118
J Chem Phys. 2006 Nov 21;125(19):194502. doi: 10.1063/1.2378921.

Using isotope substitution neutron scattering data, we present a detailed structural analysis of the short and intermediate range structures of the five known forms of amorphous ice. Two of the lower density forms--amorphous solid water and hyperquenched glassy water--have...

Two Calorimetrically Distinct States of Liquid Water Below 150 Kelvin.

Science (New York, N.Y.)

Johari GP, Hallbrucker A, Mayer E.
PMID: 8688057
Science. 1996 Jul 05;273(5271):90-2. doi: 10.1126/science.273.5271.90.

Vapor-deposited amorphous solid and hyperquenched glassy water were found to irreversibly transform, on compression at 77 kelvin, to a high-density amorphous solid. On heating at atmospheric pressure, this solid became viscous water (water B), with a reversible glass-liquid transition...
