《尚书》政治伦理思想及其发展

《尚书》是我国现存最早的一部政事记录汇编，其中保存了丰富的哲学、伦理学、政治学、社会学等思想史料。本文的意图即在通过《尚书》政治伦理思想的考察，对于先秦儒家以政治为鹄的伦理思想的发展轨迹作一点探本溯源的工作。

Graphene/polyaniline composite sponge of three-dimensional porous network structure as supercapacitor electrode

As a supercapacitor electrode, the graphene/polyaniline(PANI) composite sponge with a three-dimensional(3D)porous network structure is synthesized by a simple three-step method. The three steps include an in situ polymerization,freeze-drying and reduction by hydrazine vapor. The prepared sponge has a large specific surface area and porous network structure, so it is in favor of spreading the electrolyte ion and increasing the charge transfer efficiency of the system.The process of preparation is simple, easy to operate and low cost. The composite sponge shows better electrochemical performance than the pure individual graphene sponge while PANI cannot keep the shape of a sponge. Such a composite sponge exhibits specific capacitances of 487 F·g^(-1) at 2mV/s compared to pristine PANI of 397 F·g^(-1).
