[quick news] March 14, 2018: MIT plans to build a nuclear fusion power plant by 2033

MIT plans to build a fusion plant by 2033 MIT announced that it is carrying out a research project and plans to build a fusion plant by 2033 Compared with other energy production methods, nuclear polymerization change is more efficient, cleaner and safer, but it is very difficult to implement - the process produces extremely high temperature, which requires a large amount of energy input (currently more than energy output) MIT plans to use new superconducting materials to develop large electromagnets that can produce a magnetic field four times stronger than the current level, which will allow more energy to be generated The era of Engadget lithium battery ushers in dusk A new generation of battery power technology recently, researchers from Oxis, a British start-up company, are developing a battery composed of lithium battery and sulfur battery The energy stored per kilogram is almost twice that of the current lithium-ion battery, but after about 100 charging cycles, the battery will fail Although the battery cannot be used for a long time at present, the company said that the battery energy is more important than the price or service life in the application of systems such as UAVs, submersibles and power devices Science Apple watch can detect the blood potassium content with a sensor compatible with ECG Apple watch Alivecorkardiaband can be used to detect the risk level of blood potassium with an accuracy of 94% At present, the detection of potassium in blood is done with invasive needles In addition, when users touch the sensor, they can also detect ECG If there is arrhythmia and atrial fibrillation, the sensor will send information to the application program However, the U.S Food and drug administration has not yet approved the use of the sensor Professor Tan Weihong of theverge won the 2018 spectrochemical analysis award of the American Chemical Society Recently, academician Tan Weihong, director of the State Key Laboratory of chemical biosensor and metrology, Professor of the school of chemical engineering and the school of biology of Hunan University, won the ACS of the American Chemical Society for his fruitful achievements in the frontier research field of biological analytical chemistry Division of Analytical Chemistry Award in spectrochemical analysis), the award ceremony will be held in Boston in August this year The large-scale commercial demonstration project of the new generation of uranium enrichment centrifuges developed by CNNC will be completed on March 20, according to Wang Liming, member of the National Committee of the Chinese people's Political Consultative Conference and President of the Institute of physical and chemical engineering of nuclear industry This marks the upgrading of domestic uranium concentration centrifuges, the availability of large-scale commercial conditions, the further improvement of technical level and economy, and the international advanced level Science and Technology Daily
