1,056 seconds, a new pulse length world record for high temperature tokamak plasma has been achieved on the "artificial sun" in Institute of Plasma Physics, Hefei Institutes of Physical Sciences (HFIPS), Chinese Academy of Sciences (ASIPP). On December 30th, the experimental advanced superconducting tokamak (EAST) set this milestone of tokamak operation for longer than 1,000 seconds by the end of 2021.
Many scientists of science island, young and old, gathered on a big assembly on Dec. 20 to celebrate the 20th anniversary of HFIPS. Some government officers were also invited. In the meeting, people looked back the accomplishments of HFIPS in the past 20 years, summarized past experience and drew up a blueprint for the future.
This week is the big moment for China’s domestic fusion community since the China Fusion Energy Conference (CFEC) kicked off on Dec.5 in Hefei.
With the rapid development of industrialization and urbanization, large amount of volatile organic compounds (VOCs) have been emitted into the atmosphere, causing serious air pollution. VOCs monitoring，like metal oxide semiconductor VOCs sensor, is usually small and low-cost. However, poor selectivity, especially for VOCs molecules, is the bottleneck that limits its applications. A research group led by prof. MENG Gang conducted a series of study on VOCs molecule recognition. Important breakthroughs were made recently. The expanded NiO based sensors and smart recognition system, which was constructed by thermally modulated metal oxide sensors, realized successful discrimination of multiple VOCs with similar structure and properties.
