Multimetallic Pt-based alloys with excavated structures have attracted great interest owing to their compositional and morphological tunability, high specific surface areas, and impressive electro-catalytic activities. Herein, we report the first facile one-pot synthesis of trimetallic Pt-Ni-Cu highly excavated rhombic dodecahedrons （ERDs） with a yield approaching 100%. More importantly, these highly uniform nanocrystals have three-dimensionally accessible excavated surfaces, where abundant stepped atoms are observed. Benefiting from the highly excavated rhombic dodecahedral structures, electronic and synergistic effects within the trimetallic allo3~ and abundant stepped atoms, the as-prepared trimetallic Pt-Ni-Cu ERDs exhibit an enhanced electro-catalytic performance for the electro-oxidation of methanol compared to commercial Pt/C and bimetallic Pt-Cu ERDs and Pt-Ni-Cu solid rhombic dodecahedrons solid rhombic dodecahedrons （SRDs）.

Sanyangzhuang settlement sites is a ancient villages, which are flooded by the Yellow River in early Western Han Dynasty. A large number of pottery tiles as a part of ancient villages excavated from Sanyangzhuang sites has great value in the study of early Chinese village building. In order to preserved those well, we analyzed the properties of pottery tile by XRD（X-ray diffraction）, ESEM（Environment scanning electron microscope） and Electronics omnipotent material trial instrument for the component, structure and mechanical. The results shown that the pottery tile’s main ingredients is silicide with loose structure, low mechanical strength and high salt content, which is main reasons for pottery tile weather.

There has been an increasing interest in the Chinese excavated documents of western *** different version of excavated Laozi,it attracts the attention of *** paper examines the study of unearthed Laozi by western scholars by using Mawangtui and Guodia Laozi,attempts to give readers a basic picture of unearthed Laozi study in western *** there is no way that I can hope to introduce all western studies of unearthed Laozi,this paper will restrict the presentation to just the following topic:Mawangtui Laozi,Guodian Laozi,“Tai Yi Sheng Shui”,“Wu Xing”,and Methodology.
