China’s steel scrap standards implemented
11-29-20 At a closed-door conference held in Beijing on November 29, Chinese government bodies including the Ministry of Ecology and Environment finally approved new classification standards for the country’s steel scrap sector. Though the details are yet to be released, the new standards classify categories of steel scrap and are comparable to those in use internationally, paving the way for China to re-open its ports to approved types of foreign steel scrap. Despite the size of the China’s steel scrap industry, until now the country has lacked a unified system of steel scrap classifications and those that Chinese steelmakers and scrap collectors are presently using have been described as “crude” and at odds with those of other countries.
The release of the new China steel scrap standards may mark the first step in China’s push to diversify raw materials for steel production, a move that analysts say will reduce reliance on Iron Ore imports from Australia amid fraught bilateral ties, souring prices and in align with China’s pursuit for carbon neutrality by 2060.
12-31-20 Ministry of Ecology and Environment, National Development and Reform Commission and other five departments jointly issued a “Notice on matters relating to the standardization of the import management of recycled iron and steel raw materials,” the announcement said that products that meet the national standard of “recycled iron and steel raw materials” are not solid waste and can be imported freely. The announcement aims to regulate the management of China’s imports of recycled iron and steel materials to clarify requirements and form a synergy. According to China’s import and export regulations for recycled iron and steel materials to clarify the customs commodity code, while proposing that does not meet the “recycled iron and steel materials” national standards will be prohibited from import. The announcement will be implemented from January 1, 2021. Steel scrap standards have been officially released on December 17, the standard for the integrated use of domestic and international recycled steel raw materials resources to provide standard technical support, is conducive to promoting the high-quality development of China’s steel industry.
Irradiation technology
Irradiation technology is expected to be used to kill coronavirus found in cold chain food, said China National Nuclear Corporation on Thurs. There have been multiple reports in China of imported cold-chain food packaging testing positive for COVID19.
China prepares to launch Long March-8 Y1 rocket
China’s Long March-8 Y1 rocket was vertically transported to the launching area of the Wenchang Spacecraft Launch Site in south China’s Hainan Province on Wednesday. Next, the rocket will be filled with propellant and readied for launch in late December.

China launches two satellites for gravitational wave detection
12-10-20 China sent two satellites for the detection of gravitational waves into planned orbit from the Xichang Satellite Launch Center in Sichuan Province.
The two satellites, which compose the Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor (GECAM) mission, were launched by a Long March-11 carrier rocket( 355th mission).
The GECAM satellites will be used to monitor high-energy celestial phenomena such as gravitational wave gamma-ray bursts, high-energy radiation of fast radio bursts, special gamma-ray bursts and magnetar bursts, and to study neutron stars, black holes and other compact objects and their merger processes.
In addition, they will also detect high-energy radiation phenomena in space, such as solar flares, Earth gamma flashes and Earth electron beams, providing observation data for scientists.
Gaofen-14
China launched Gaofen-14, an optical satellite, onboard the Long March 3B carrier rocket on Sunday 11:58 am from Xichang Satellite Launch Center in SW China’s Sichuan Province.
First ArF photoresist production line
The first ArF photoresist production line by Nanda Optoelectronics has been officially put into production. It is estimated that the annual sales will reach 1 billion yuan after the project is fully operational.
Photoresist 光刻胶 is the core material for the production of integrated circuits, which mainly plays the role of “transferring the designed image from the template to the appropriate position on the wafer surface”. Therefore, the quality and performance of the photoresist have an important impact on the final product and performance of the chip. High-end types such as ArF photoresist almost rely 100% on imports.
The criteria for hypersonic airbreathing propulsion and its experimental verification
It is the first time to verify the oblique detonation engine concept successfully with wind tunnel tests and the standing oblique detonation undergoes the initiation, transition and full-developed stages. The experiments also demonstrated well the criteria proposed in this paper. According to research progresses on oblique detonation engines, the Sodramjet engine is very promising for hypersonic airbreathing propulsion because that the engine system is simple in its structure, efficient in the thermo-cycle, broad in its operation Mach number range and low in aerothermodynamic heating load.
