Treatment of ZSM-5 and Y zeolites with aqueous NH 4 BF 4 (secondary synthesis) yields [B]ZSM-5 and [B]Y. Tetrahedral B 3+ in the zeolite framework was verified by boron MAS NMR (B 3+ shift: ZSM-5=-3.6 ppm; Y=-2.7 ppm). B 3+ chemical shift was found t

It has been proposed that sympatric bumblebee species form mimicry rings to profit from learnt avoidance behaviour by predators. This hypothesis can be tested by comparing the predation rates of local bumblebees with those of imported non-native bumb

In a recent interesting letter Dessau et al. presented FTIR and 29Si (CP) MAS NMR results providing further evidence for the presence of internal silanol groups in ZSM5. The decrease in the silanol groups during a steaming procedure accompanied by a
