High quality development research in orange, purple, blue, green... When we entered the China Spallation Neutron Source Experiment Hall, we saw a variety of spectrometers like colorful petals, stretching out from the center of the target station. What is the use of these different colored spectrometers? "It's very useful!" Chen Hesheng, an academician of the CAS Member and the chief commander of the China Spallation Neutron Source Project, told reporters that the spallation Neutron source is like a "super microscope", and the neutrons generated by it are like "probes". Through different spectrometers, the internal structure of materials can be clearly detected: from mobile phone chips and DNA to deep-sea Submersible and high-speed rail wheels. "For example, how many miles should the wheels of the high-speed railway be replaced? This requires the use of engineering material stress diffractometer." Chen Hesheng introduced that by measuring and studying the residual stress of the wheels with this spectrometer, we can evaluate the mileage and time of use to ensure safety and give consideration to economy. "In the last month, we were measuring the domestic high-speed railway wheels. These key data related to the operation safety and performance evaluation of the high-speed railway will lay the foundation for the identification and mass use of our domestic high-speed railway wheels," said Chen Hesheng. The China Spallation Neutron Source, located in Songshan Lake Science City, Dongguan City, Guangdong Province, is the first major scientific and technological infrastructure in the Guangdong–Hong Kong–Macao Greater Bay Area. The advantage of being located at an important node of the Guangzhou Shenzhen Hong Kong Science and Technology Innovation Corridor has enabled it to maintain close cooperation with scientific research institutions and universities in Hong Kong and Macao since the beginning of construction. Conducting experiments at home is so convenient! "Said Professor Huang Mingxin from the University of Hong Kong, unable to suppress her excitement. Since the China Spallation Neutron Source was put into operation, it is no longer necessary for him to apply to foreign spallation Neutron source for each experiment, and the experiment efficiency has been greatly improved. The "Super Steel" developed by Huang Mingxin's team has amazed the world with its super strength and super toughness. "A sample of 'super steel' with the size of 1 square centimeter and the thickness of 1.5 mm can bear the weight of 3 tons, which is equivalent to the weight of an adult Asian elephant," said Huang Mingxin. The microscopic principle discovered by the general powder diffractometer of China Spallation Neutron Source provides key data support for continuous improvement of fracture, toughness and corrosivity of this steel. The reporter learned that since it was put into operation in August 2018, China Spallation Neutron Source has more than 4500 registered users worldwide and completed more than 1000 projects. Its scientific achievements cover energy, physics, materials, life sciences and other frontier and cross cutting fields, and constantly attract advanced scientific research institutions, high-tech talents and foreign scientists to settle down in the Bay Area. On the east bank of the the Pearl River, many small and medium-sized enterprises that introduce advanced technology into daily applications also burst out with strong innovation and creativity. Entering the exhibition hall of Guangdong Boliwei Technology Co., Ltd., a national high-tech enterprise, a dazzling array of new energy products allows people to glimpse the green innovation of their way of life: from the popular electric bicycles in Europe to the essential mobile power supply for outdoor camping; From the "little assistant" intelligent robots in daily life to the household energy storage system for dealing with power shortages - behind these products, there is a core that cannot be separated, which is lithium batteries. From starting a company in 2010 to becoming a Chinese lithium-ion battery manufacturer
