49_50/2010Cover Picture: High-Surface-Area Silica Nanospheres (KCC-1) with a Fibrous Morphology (Angew. Chem. Int. Ed. 50/2010)

The chemist's first choice for heterogeneous catalysts is often porous silica because of its high surface area. However, these surface areas are mostly due to the pores and are thus not always accessible. V. Polshettiwar, J. M. Basset, and co-workers describe in their Communication on page 9652 ff. how they synthesized fibrous silica nanospheres with a high surface area. Such a fibrous morphology observed in these nanospheres has not been seen before in silica materials.
