The Shenyang Institute of Automation of the Chinese Academy of Sciences 中科院沈阳自动化研究所 developed the “Exploration 1000” 探索1000 underwater robot to complete 35 hours in sea trial, obtained a number of polar ocean data. This is the first time an underwater robot has operated at high Antarctic latitudes for extended periods of time.
“Deep Sea 01” hazardous materials emergency command vessel
“Deep Sea 01″深海01 is a hazardous materials emergency command vessel that can be used for monitoring, surveillance, accident response and personnel rescue in the area of LNG and other hazardous gases emergency at sea. It is also the first law enforcement official ship in the world to adopt a micro-positive pressure maintenance system in the cabin to monitor, supervise and navigate in the LNG proliferation zone.
The length of the ship is 78 meters, width 12.8 meters, depth 5.5 meters, design draft 3.4 meters and full load displacement 1,450 tons.The ship uses 3 diesel gensets (3X2080 kW) plus 2 lithium iron phosphate power batteries (2X750 kWh) “oil-electric” hybrid propulsion, dual full-swing pod thrusters, with DP 1 power positioning function. The ship has a crew of 60, a design speed of 18 knots, wind resistance class 12, and a range of 1000 nautical miles. The helicopter landing platform can be used for the landing and take-off of the domestic rescue helicopter at sea. Equipped with advanced equipment such as liquefied natural gas (LNG) gas detection system, ship air pollutant emission detection system, sea surface oil spill monitoring radar, X-band explosion-proof radar and underwater robot (ROV), the ship employs a comprehensive information system that combines maritime law enforcement, emergency command and ship management.
The ship was financed by the Shenzhen Municipal People’s Government, and constructed by the Shenzhen Maritime Bureau. “Deep Sea 01” will be officially commissioned in 2020., will be responsible for the safety supervision, oil spill surveillance, atmospheric monitoring and accident emergency response in Guangdong water, including Hong Kong, Macao and the Greater Bay Area.

70-meter Mars antenna reflector in Tianjin Wuqing
The National Astronomical Observatory installed the 70-meter Mars antenna reflector in Tianjin Wuqing 天津武清 yesterday 4-25-20. The largest single aperture fully movable antenna in Asia, provides a solid foundation for China’s deep space exploration. The high performance receiving antenna with a total weight of about 2,700 tons, 72 meters high, the diameter of the main reflecting surface is 70 meter, composed of 16 laps of 1328 high-precision panels, has an area equivalent to nine basketball courts.
A 5G LEO (low earth orbit) satellite by Beijing-based commercial satellite company Galaxy Space passed the test of a 3-minute-video call
https://bit.ly/2zwZTHM?fbclid=IwAR33fagcq6CMDKPADLTBBdB3CG9tBMXC3yyO1e9OGz3ZIdDstCsGEjcmHCs A 5G LEO (low earth orbit) satellite by Beijing-based commercial satellite company Galaxy Space passed the test of a 3-minute-video call by connecting to the WiFi hotspots provided by the satellite terminal. The picture is clear and the response is swift.
As many satellite startups plan to launch small satellites into low-Earth orbit (LEO) to provide global broadband internet services, a Chinese satellite provider now suggests the use of 5G speeds for the purpose.
The call comes as China attaches more importance to the development of the satellite-enabled mobile internet and includes the area in its “new infrastructure” construction plan, which could offer both short-term relief and a long-term boost to the economy.
Beijing-based private aerospace company Galaxy Space recently held an experimental 3-minute video call by connecting to Wi-Fi hotspots provided by a satellite terminal. Galaxy Space launched China’s first LEO 5G broadband satellite that went into orbit earlier this year.
The clear picture and swift response in the video call on Friday proved that the LEO 5G broadband satellite developed by the private startup is reliable, while a race between the world’s top economic superpowers to roll out 5G networks goes on.
The National Development and Reform Commission included the satellite internet into the “new infrastructure” list on April 20, ramping up its efforts to develop the technology.
China’s National Blockchain Will Change the World
https://finance.yahoo.com/news/china-national-blockchain-change-world-182614309.html Professor Michael Sung is founder and chairman of CarbonBlue Innovations, a tech transfer platform for commercializing internationally sourced blockchain, fintech and digital finance innovation in developing countries. He is also co-director of the Fintech Research Center at the Fanhai International School of Finance at Fudan University.
This week, China will officially launch a major new blockchain initiative called the Blockchain-based Services Network (BSN). The BSN is a critical part of China’s national blockchain strategy that was announced by President Xi in late November 2019, but went largely under the radar as the simultaneous announcement of China’s digital RMB currency, called the DCEP, swept the world by storm. Only recently has the Western media recognized the significance of the BSN, which sees its mainland commercial launch April 25. The portal’s global commercial launch is scheduled for June 25.
Huawei said to tap NEV charging field by launching “HiCharger” DC fast-charging module
Huawei will reportedly launch on April 24 a new DC fast-charging module product, which will act as a solution to NEV charging infrastructures.
The upcoming solution, dubbed “Huawei HiCharger”, has partnered with several Chinese companies, such as State Grid, Star Charge, China Southern Power Grid Electric Vehicle Service Co.,Ltd., Huashang Sanyou, Titans as well as Dalian Luobinsen, according to a local media outlet.
The release of HiCharger signals Huawei’s beginning of the offensive into NEV charging domain. The leading smart device supplier has repeated in the public its ambition to be a core “increment parts” supplier for intelligent-connected vehicle (ICV) rather than a car manufacturer.
Breakthrough in precision bearing research and development: speed increased by 50%
Although China’s bearing industry has developed rapidly for many years, it has now become the third largest bearing country in the world in terms of bearing output and sales, but the key technology areas still need to be strengthened, especially the gap between the aerospace bearing technology and the first bearing is obvious.
It is speculated that hybrid ceramic bearings have been initially applied in the field of China’s new turbofan 15 aero engine and transmission.
China’s new solar telescope is for now the biggest in operation
- Scientist says it will be used to monitor solar activity and provide more accurate data to support research and space weather forecasting
- The world’s largest and most powerful – with a 4-metre aperture – is in Hawaii, and is expected to be ready for use in July https://www.scmp.com/news/china/science/article/3076775/chinas-new-solar-telescope-biggest-operation-now?fbclid=IwAR2Y0SPkvx4gyNCvIgY99agqU6448ulfSSbZW4uERRzzZdI_W3btI7ObWuQ
Scientists in southwest China on Tuesday said they had built the world’s second biggest solar telescope, which they say will provide more accurate data and improve forecasting.
With a 1.8-metre aperture, the Chinese Large Solar Telescope (CLST) was developed by the Institute of Optics and Electronics at the Chinese Academy of Sciences in Chengdu, Sichuan province.
Researchers achieve a 10x supercapacitor energy density breakthrough
Supercapacitors can charge almost instantly, and discharge enormous amounts of power if needed. They could completely erase the Achilles heel of electric vehicles – their slow charging times – if they could hold more energy. And now Chinese and British scientists say they’ve figured out a way to store 10 times more energy per volume than previous supercapacitors.
A team split between University College London and the Chinese Academy of Sciences has released a study and proof of concept of a new supercapacitor design using graphene laminate films and concentrating on the spacing between the layers, the researchers discovering that they could radically boost energy density when they tailored the sizes of pores in the membranes precisely to the size of electrolyte ions.
Using this design, the team says it’s achieved a massive increase in volumetric energy density. Where “similar fast-charging commercial technology” tends to offer around 5-8 watt-hours per liter, this new design has been tested at a record 88.1 Wh/l. The team claims it’s “the highest ever reported energy density for carbon-based supercapacitors.”
