Metamorphic materials: Restructuring siliceous mesoporous materials*

Effective tailoring of pore sizes in mesoporous molecular sieves (see Figure) has been achieved by a novel method involving the restructuring of the mesopores under mild aqueous conditions. A studyis reported aimed at elucidating the underlying chemistry. It is suggested that further investigation could provide insight into natural biomineral resorption and lead to materials with enhanced biocompatibility characteristics magnified image .
