A hidden Markov model for describing turbostratic disorder applied to carbon blacks and graphene
A G Hart, T C Hansen, W F Kuhs
We present a mathematical framework to represent turbostratic disorder in materials like carbon blacks, smectites, and twisted -layer graphene. In particular, the set of all pos…
A Markov theoretic description of stacking disordered aperiodic crystals including ice and opaline silica
Allen G Hart, Thomas C Hansen, Werner F Kuhs
We review the Markov theoretic description of 1D aperiodic crystals, describing the stacking-faulted crystal polytype as a special case of an aperiodic crystal. Under this descript…
Cage occupancies of methane hydrates: Results from synchrotron X-ray diffraction and Raman spectroscopy
Junfeng Qin, Christiane D. Hartmann, Werner F. Kuhs
An accurate knowledge of cage occupancy of methane is central for understanding the physical-chemical properties of gas hydrates, the actual inventory of natural gas in hydrate dep…
The structure and cage filling of gas hydrates as established by synchrotron powder diffraction data
Christiane D. Hartmann, Susanne Hemes, Andrzej Falenty +1
Synchrotron powder diffraction data were measured on various gas hydrates prepared at different fugacities and recovered to low temperatures. The data extend to sin θ/λ values of a…
Formation of porous gas hydrates
Andrey N Salamatin, Werner F Kuhs
Gas hydrates grown at gas-ice interfaces are examined by electron microscopy and found to have a submicron porous texture. Permeability of the intervening hydrate layers provides t…
CO2 hydrate dissociation at low temperatures - formation and annealing of ice Ic
Andrzej Falenty, Thomas C. Hansen, Werner F. Kuhs
Dissociation of gas hydrates below 240 K leads to the formation of a metastable form of water ice, so called cubic ice (Ic). Through its defective nature and small particle size th…
Lattice constants and expansivities of gas hydrates from 10K up to the stability limit
Thomas C. Hansen, Andrzej Falenty, M. Mangir Murshed +1
In a combination of neutron and synchrotron diffraction the lattice constants and expansivities of hydrogenated and deuterated CH4-, CO2-, Xe- (structure type I) and N2-hydrate (st…
