BEIJING, Dec. 29 (Xinhua) -- The following is a summary of published science and technology news of China:

NEV

Chinese smartphone maker Xiaomi unveiled its first new energy vehicle (NEV) at a launch event in Beijing on Thursday.

The SU7 has been put into production and is estimated to enter the market in 2024, Xiaomi said.

Xiaomi has invested more than 10 billion yuan (about 1.41 billion U.S. dollars) in its first-stage auto research and development, which involves a team of over 3,400 engineers, the company said.

SAR SATELLITES

China's L-SAR 01 satellite group has been officially put into use after completing in-orbit tests, according to the China National Space Administration.

China's L-SAR 01 is a satellite group composed of two satellites equipped with L-band synthetic aperture radar (SAR), namely the L-SAR 01A and the L-SAR 01B.

The SAR is a microwave-imaging radar system that emits electromagnetic waves to Earth and receives echoes. It can take all-weather, round-the-clock, high-resolution microwave pictures of land surfaces.

ETHANOL

The world's largest ethanol production equipment, with an annual output of 600,000 tonnes, went into trial in Huaibei City, east China's Anhui Province.

The equipment can convert coke oven gas into ethanol, which will massively increase the added value of coal and provide a feasible way for the low-carbon development of steel and petrochemical industries.

Adopting the advanced technology jointly developed by the Dalian Institute of Chemical Physics (DICP) under the Chinese Academy of Sciences and Shaanxi Yanchang Petroleum (Group) Co., Ltd., the equipment was constructed by Tanxin Technology Co., LTD. under the Huaibei Mining Group. Enditem
