A new genus and species of fossil trachypachid Fortiseode pervalimand Jia & Ren gen. et sp. nov., is described and illustrated. The new fossil with large and strong mandibles, short and robust legs, and pronotum widest near apical angle differs from other members of Eodromeinae. It is the first record of fossil trachypachid from the Mesozoic Yixian Formation of Huangbanjigou, Liaoning, China.

In this work, N,N,propyl-trimethoxysilane was prepared as a multidentate functional monomer. The 3D model of the monomer coordinating with Cu 2+ indicated that the monomer is able to provide five ligating atoms like ethylenediaminetetraacetic acid-Cu 2+ to complex with Cu 2+ .When Cu 2+ was used as a template ion, the synthesis conditions of Cu 2+ -imprinted polymers were optimized upon orthogonal design. It is interesting to find that Cu 2+imprinted polymer offers a selectivity coefficient of 192.2 when the molar ratio of Cu 2+ to monomer was exactly 1:1. That means there is no excess ligating atom in the ion-imprinted polymer and therefore, the nonspecific adsorption could be avoided.Benefiting from the excellent selectivity of Cu 2+ -imprinted polymer, even if the concentration of Zn 2+ was 25 times that of Cu 2+ , Cu 2+ -imprinted polymer still affords a high selectivity coefficient. Finally, the optimal synthesis conditions for Cu 2+imprinted polymer, except the pH, were adopted to prepare Ni 2+ -imprinted polymer, and Ni 2+ -imprinted polymer also offered satisfying selectivity to Ni 2+ . That implies this multidentate monomer is adaptable in ion imprinting and, the optimal synthesis conditions of Cu 2+ -imprinted polymer except pH are likely suitable for the imprinting of other ions besides Cu 2+ .
