Properties of CO clathrate hydrates formed in the presence of MgSO solutions with implications for icy moons
E. Safi, Stephen P. Thompson, Aneurin Evans +6
There is evidence to suggest that clathrate hydrates have a significant effect on the surface geology of icy bodies in the Solar System. However the aqueous environments believed t…
In situ apparatus for the study of clathrate hydrates relevant to solar system bodies using synchrotron X-ray diffraction and Raman spectroscopy
Sarah J. Day, Stephen P. Thompson, Aneurin Evans +1
Clathrate hydrates are believed to play a significant role in various solar system environments, e.g. comets, and the surfaces and interiors of icy satellites, however the structur…
Photoluminescence in amorphous MgSiO_3 silicate
S. P. Thompson, J. E. Parker, S. J. Day +2
Samples of amorphous MgSiO_3 annealed at temperature steps leading up to their crystallisation temperature show a rise in photoluminescence activity, peaking at ~450C. The photolum…
Non-aqueous formation of the calcium carbonate polymorph vaterite: astrophysical implications
Sarah J. Day, Stephen P. Thompson, Julia E. Parker +1
We study the formation of calcium carbonate, through the solid-gas interaction of amorphous Ca-silicate with gaseous CO2, at elevated pressures, and link this to the possible prese…
Carbonate Formation in Non-Aqueous Environments by Solid-Gas Carbonation of Silicates
S. J. Day, S. P. Thompson, A. Evans +1
We have produced synthetic analogues of cosmic silicates using the Sol Gel method, producing amorphous silicates of composition Mg(x)Ca(1-x)SiO3. Using synchrotron X-ray powder dif…
