Amorphous calcium carbonate (ACC) is regularly listed as one of the known calcium carbonate phases, first being identified in 1984. Although ACC is inherently unstable, it is a...

We are convinced that a careful study of the atomic structure of a-FePO4 would provide very interesting insights into several phosphate systems, including phosphate glass...

Amorphous calcium sulfate (ACS) is transitory phase in the precipitation of calcium sulfate minerals such as gypsum. ACS is also be present in mineral systems which may be...

The present proposal is part of a larger EPSRC project advancing the vibrational spectroscopy of silicate glasses. The project involves the techniques of IR and Raman...

Amorphous iron sulfate pentahydrate has been identified as one of the iron sulfates found on the Martian surface during the Spirit and Opportunity Rover missions in recent...

Amorphous calcium carbonate (ACC) is a transient phase in one of the most important biomineralisation systems in animals (s.g.) such as crustaceans. The literature reports many...

We wish to perform neutron diffraction measurements on glass samples of SiO2 and 30CaO.70SiO2 containing both natural oxygen and 18O. The oxygen scattering lengths are almost...

One important structural application of oxide glasses is for nuclear waste immobilisation. Recent reports have highlighted the possibility of iron phosphate glasses as an...
