As a class of important crystalline porous materials,zeolites which were first found in 1756 have now been widely used in chemical industries for catalysis,adsorption and separation.35232 patents with the title including Hzeolite*n are documented by Derwent Innovations Index on January 2,2020[1].Despite of spread applications of zeolites and related-materials in industry,fundamental research of zeolites and their applications are still desired in both academia and industry,as shown in Fig.1.

We concentrate on the skin effects and topological properties in the multilayer non-Hermitian su−Schrieffer−Heeger (SSH) structure, by taking into account the nonreciprocal couplings between the different sublattices in the unit cells. Following the detailed demonstration of the theoretical method, we find that in this system, the skin effects and topological phase transitions induced by nonreciprocal couplings display the apparent parity effect, following the increase of the layer number of this SSH structure. On the one hand, the skin effect is determined by the parity of the layer number of this SSH system, as well as the parity of the band index of the bulk states. On the other hand, for the topological edge modes, such an interesting parity effect can also be observed clearly. Next, when the parameter disorders are taken into account, the zero-energy edge modes in the odd-layer structures tend to be more robust, whereas the other edge modes are easy to be destroyed. In view of these results, it can be ascertained that the findings in this work promote to understand the influences of nonreciprocal couplings on the skin effects and topological properties in the multilayer SSH lattices.

Monolayer chemically converted graphene （CCG） nanosheets can be homogeneously self-assembled onto silicon wafer modified by 3-aminopr- opyl triethoxysilane （APTES） to form very thin graphene film. The CCG film was characterized by FT-IR, XRD, SEM, TEM and AFM. Results show that CCG sheets formed monolayer film after assembled onto silicon wafer and there is a very tight chemical bond between sheets and wafer. Furthermore, the electrical measurements revealed that the monolayer graphene film has an excellent electrical conductivity.

Hierarchy is present everywhere in our planet, from family, society, urban construction, ecological systems to living organisms,although usually we neglect it. In the biosystem, to achieve transfer, exchange and transformation of substances and energy with extremely high efficiency and minimized energy consumption,evolution by natural selection has endowed many classes of organisms with hierarchically porous networks.
