1Refresh the world record! A breakthrough has been made in the field of lithium-ion batteries. Recently, Chen Jun, an academician of the Chinese Academy of Sciences and a professor at the School of Chemistry of Nankai University, and his team designed and synthesized an ultra-high-capacity organic cathode material for lithium-ion batteries - cyclohexanexone, which contains the earth's abundant carbon. , hydrogen, and oxygen elements, and this type of organic cathode material shows the highest capacity value currently reported for lithium-ion batteries, setting a new world record for the capacity of organic cathode materials for lithium-ion batteries. 2 State Grid has launched the construction of the "National and Local Joint Engineering Research Center for Chips". State Grid announced that it has launched the construction of the "National and Local Joint Engineering Research Center for Energy Internet Intelligent Terminal Core Chip Reliability Technology." The center will be dedicated to the research of key technologies of power chips and is a national-level experimental research platform for strategic emerging industries and solving key core technical problems. 3 Samsung Semiconductor’s second-phase project investment in Xi’an will exceed US$14 billion. We learned from Samsung (China) Semiconductor Co., Ltd. located in Xi’an High-tech Zone that the total investment in the second-phase Samsung Semiconductor high-end memory chip project will exceed US$14 billion. The second phase of the project started construction in March 2018 and is expected to be completed in July this year and mass production will be achieved in the first quarter of 2020. 4 Borealis strengthens its global supply of short glass fiber compounds. Borealis, together with its customers and local distinguished guests, announced the opening of its new polypropylene (PP) compounds plant in Taylorsville, USA, marking its global expansion. . The 50,000-square-foot facility adds 66 million pounds of initial capacity to strengthen Borealis and Borouge's global supply capabilities in thermoplastic olefins and short glass fiber compounds. The first batch of compounds produced at the new plant will be used primarily to produce automotive interior and exterior parts for major OEMs and Tier 1 suppliers. 5 Preparation and visual strain measurement of flexible photonic crystals inspired by chameleons Recently, the team of Li Bo and Chen Hualing of the Institute of Robotics and Intelligent Systems, School of Mechanical Engineering, Xi'an Jiaotong University proposed and demonstrated a method for preparing flexible photonic crystals based on nanoimprint transfer. , and the prepared material is applied to high-sensitivity visual strain measurement in the low strain range. 6 Qidong International Economic and Trade Fair attracted 27.8 billion yuan in investment. The Qidong International Economic and Trade Fair opened recently, and a large project order worth 27.8 billion yuan was signed on site. During the Economic and Trade Fair, Qidong signed a total of 30 projects, involving offshore engineering, logistics, cultural tourism, electronic information, new materials, new energy, etc. Among them, there are 10 foreign-invested projects with a total investment of US$1.22 billion.
