Characteristics of clathrate hydrate equilibria in mesopores and interpretation of experimental data
Article Abstract:
The features of the clathrate hydrate equilibria in mesoporous media are discussed in terms of a conceptual model, with the aim of resolving current inconsistencies concerning experimental and interpretative methods employed in studies of such systems. It is concluded that the Gibbs-Thomson (or Kelvin) relationship used to model clathrate inhibition in porous media must be modified correctly to reflect the hysteries between growth and dissociation.

Experimental measurement of methane and carbon dioxide clathrate hydrate equilibria in mesoporous silica
Article Abstract:
Experimental structure-I clathrate hydrate equilibrium and ice-melting data for mesoporous silica glass is presented. The Gibbs-Thomson relationship is used to describe the temperature depression of clathrate dissociation conditions in cylindrical pores. It is observed that in both cases, high capillary pressures result in depressed solid decomposition temperatures, as a function of pore diameter.

Fast photoreduction of a heme peptide encapsulated in nanostructured materials
Article Abstract:
Photoreduction of the microproxidase-11 Fe(super III) center is observed to occur in the immobilized samples and results in a long-lived stable reduced heme. The source of the electron resulting in reduction of the heme is proposed to originate from the silica matrix, and functionalization of silica surface is suggested to facilitate electron transfer to the heme.
