    Lockheed Martin, the largest 3D printing satellite component in history, has built the largest 3D printing component ever used in outer space: a titanium dome with a diameter of four feet and a cap for a satellite fuel tank (the largest before was just the size of a toaster) Moreover, the biggest advantage of 3D printing is to save titanium materials, improve production speed and reduce costs: "we can produce satellites twice as fast as before, and the cost is only half of it." Https:// experiment flash technology It is planned to manufacture a kind of optogenetic technology detected by scientists of high precision hearing aids in gerbils If it can be replicated in humans, better hearing aids can be developed German scientists have successfully used flash to restore the hearing of gerbils If this technology is developed for human beings, it can provide more precise and high-resolution hearing experience than existing hearing devices, such as cochlear implants, and help people with hearing impairment to know the world through sound and sound again Https://spectrum.ieee.org/the-human-os/biomedical/devices/device-restores-hearing-using-light machine learning design model helps break the world record At present, the world bicycle speed record is maintained by the Dutch in 2012, but now Switzerland plans to reverse this record They developed an aerodynamically trained algorithm that could simplify their bikes, reduce air drag and create new records The researchers say that machine learning has great flexibility in situations where traditional methods cannot be applied The technology has been split into an independent company, and the research team will apply the model in the world human speed challenge Https://techcrunch.com/2018/07/12/machine-learning-boosts-swiss-startups-shot-at-human-powered-land-speed-record/pure carbon negative electrode material can make electric vehicles achieve a 600 km endurance A special carbon anode material for high capacity and high density lithium battery with pure carbon as the main component has been developed in Keda Coal Chemical Research Institute At present, the new lithium battery for electric vehicle based on this material has been officially trial produced in Chengdu Nanguang new energy company According to the experimental data and product performance test, the lithium battery made of the new material can achieve the vehicle range of more than 600 km Http:// the electric drive system of domestic maximum power 5500hp shale gas fracturing pump was offline July 13 It was learned from CRRC Yongji Electric Co., Ltd that the electric drive system of domestic maximum power 5500hp shale gas fracturing pump was offline, which marks the breakthrough of core technical equipment for shale gas exploitation in China According to the introduction, this system is the first domestic six phase frequency conversion electric drive fracturing pump system, which can realize the multi-phase redundant control of the motor and greatly enhance the reliability http://
