Periodic mesoporous materials of the type (R'O) 3Si-R-Si(OR') 3 with benzene as an organic bridge and a crystal-like periodicity within the pore walls were functionalized with SO 3H or SO 3 - groups and investigated by ...

Functionalization by changing the topography of workpiece surfaces is interesting for many applications. Lasers - especially ultrashort pulse lasers - are flexible tools for this kind of tasks. Besides deterministic ...
