According to the research plan of the EAST physics experiment, two sets of neutral beam injectors （4-8 MW, 10-100s） were built and operated in 2014. We present the development of the EAST neutral beam injector （NBI） and the latest experiment results obtained on the test-stand about operation of ion source, beam extraction, and measurement of key parameters. Those results show that all targets reach or almost reach the design targets. All these lay a solid foundation for the achievement of plasma heating and current drive for EAST in 2014.展开更多

Using the DBC technologythick copper foils (0.125mm - 0.Tmm) arecladded to Alumina or Aluminum Nitride,The strong adhesion of the copper to ceramicbond reduces the thermal expansion coefficientin horizontal direction only slightly above theTEC of the ceramic itself. This allows directsilicon attach of large dies without using TECcontrolling layers.As DBC technology is using copper foils,integralleads overhanging the ceramic can be realized...展开更多

Hence, considering the vast naturally available resources of potassium all over the world and its encouraging intercalation chemistries, it has recently enticed attention in electrochemical energy storage industry in the form of potassium ion batteries (PIBs). The major factor in this K+ based battery, is to develop efficient approaches to manufacture electrode substance to intercalate its big size potassium ions with considerable voltage, kinetics, charge/discharge capacity, capacity retention, cost, etc. This study contributes in the recent developments of anode and cathode materials for PIBs, including several electrode materials in regards to synthesis, structure, electrochemical performance, and K-storage mechanisms. Finally, the review contributes to provide helpful sources for the increasing number of scientists working in this industry regarding its critical issues and challenges and also to indicate the future direction of electrode materials in PIBs.展开更多

Prof. NIE Hong, the Vice President of NUAA, represented the host address and expressed welcome and gratitude to all the guests from home and abroad. He said the development of the technologies, environmental protection and the trade globalization require to continually improve the performance of products, and accurately select proper material and the manufacturing technology. As the revolutionary technology in casting development history, LFC technology has brought a brand-new change for the machine design and casting production. He hoped the conference would be beneficial to the development of Chinese LFC technololy and wished the symposium a complete success! Prof. YE Sheng-ping, the Executive Chairman of the conference and the Director of LFC Committee of FICMES, gave the opening address and read out the congratulations of F. J.
