Hierarchically organized zeolites are materials retaining the crystalline order and associated functionality of bulk zeolites while also integrating a multilevel pore network. Here, the authors review the raft of techniques applied to characterize their crystal, pore and active site structures.

The results of a new search for positronium decays into invisible final states are reported. Convincing detection of this decay mode would be a strong evidence for new physics beyond the standard model (SM): for example, the existence of extra\char21{}dimensions, of milli-charged particles, of new light gauge bosons or of mirror particles. Mirror matter could be a relevant dark matter candidate. In this paper the setup and the results of a new experiment are presented. In a collected sample of about
