Alkali Halide Nanotubes Structure and Stability

201231 The fact that stable nanotube structures were also found for NaCl and KBr suggests that this geometry may be widely implemented in material sciences and that ionic nanotubes can be as stable as the typical B1 and B2 crystal structures normally associated with ionic solids thus opening a new possibility for the 3D macroassely of alkali halide

AlkaliResistant Mechanism of a Hollandite DeNOx

A thorough understanding of the deactivation mechanism by alkalis is of great importance for rationally designing improved alkaliresistant deNOx alysts but a traditional ionexchange mechanism cannot often accurately describe the nature of the deactivation thus hampering the development of superior alysts Here we establish a new exchangecoordination
