　　Ongoing research and development of ultra-high performance concrete (UHPC) in the Czech Republic has been utilized in design and implementation of light-weight segmental deck of the cable-stayed footbridge over the Labe River in Celakovice with main span of 156 m.Detailing, design issues, construction method and efficiency of using UHPC on this large span lightweight bridge is described in the paper.The superstructure of the Celakovice footbridge was completed in the December 2013 and the bridge was opened for the public in April 2014.Main advantages of this project is not only low maintenance and reasonable life cycle cost but also favourable tender price which was achieved by the contractor Metrostav a.s.due to combination of high-strength modem materials steel and UHPC.

氟盐体系制备SmFe合金的电化学机理研究
金属钐是重要的稀土元素之一，是制备高性能稀土永磁材料、储氢材料、核控制材料等高技术材料必不可少的基础材料。目前，镧热还原蒸馏法是工业生产金属钐的唯一方法，属间歇生产，设备要求高、生产周期长、加工成本很高，因此，科技工作者一直在探索廉价金属钐生产工艺的可能性，其中熔盐电解法是生产稀土金属及合金最主要方法，其生产成本最低，但由于Sm的变价特性，工业上采用熔盐电解法制备金属钐及其合金一直未获得成功。
