Molecular Dynamic Simulations of Clathrate Hydrate Anomalous Preservation: The Effect of Coating Clathrate Hydrate Phases

open access: yesThe Journal of Physical Chemistry C, 2019
In this work, the effect of cyclopentane (CP) clathrate hydrate on the anomalous preservation of tetrahydrofuran (THF) hydrate under conditions outside its stability region is studied by using molecular dynamics simulations. The decompositions of pure structure II THF and CP clathrate hydrate, and also THF hydrate coated by CP hydrate, all with outer ...

Refined Structure of Metastable Ice XVII from Neutron Diffraction Measurements

open access: yes, 2016
The structure of the recently identified metastable ice XVII, obtained by release of hydrogen from the C$_0$ D$_2$O-H$_2$ compound (filled ice), has been accurately measured by neutron powder diffraction.

Crystalline Water Structure in Room‐Temperature Clathrate State: Hydrogen‐Bonded Pentagonal Rings

open access: yesSmall Structures
Water hydrogen bonding is extremely versatile; ≈20 ice structures and several types of clathrate hydrate structures are identified. These crystalline water structures form at temperatures below room temperature and/or at high pressure.

On the Scale-up of Gas-Hydrate-Forming Reactors: The Case of Gas-Dispersion-Type Reactors

open access: yesEnergies, 2015
For establishing hydrate-based technologies for natural-gas storage/transport, CO2 capture from industrial flue gases, etc., we need appropriate guidelines for the scale-up of hydrate production/processing equipment from laboratory scales to industrial ...

Clathrate type 2 hydrate formation in vacuo under astrophysical conditions [PDF]

open access: yes
The properties of clathrate hydrates were used to explain the complex and poorly understood physical processes taking place within cometary nuclei and other icy solar system bodies.

CO2-SO2 clathrate hydrate formation on early Mars

open access: yesBIO Web of Conferences, 2014
Most sulfate minerals discovered on Mars are dated no earlier than the Hesperian. We showed, using a 1-D radiative-convective-photochemical model, that clathrate formation during the Noachian would have buffered the atmospheric CO2 pressure of early Mars

Clathrate hydrate FTIR spectroscopy - infrared signatures, astrophysical significance

open access: yesBIO Web of Conferences, 2014
Clathrate hydrates, ice inclusion compounds, are of major importance for the Earth’s permafrost regions and may control the stability of gases in many astrophysical bodies such as the planets, comets and possibly interstellar grains.
