The Chinese Academy of Sciences (CAS), is a Chinese research institute. It has historical origins in the Academia Sinica during the Republican era and formerly also known by that name, is the national academy for the natural sciences of the People's Republic of China (PRC). Collectively known as the "Two Academies (两院)" along with the Chinese Academy of Engineering, it functions as the national scientific think tank and academic governing body, providing advisory and appraisal services on issues stemming from the national economy, social development, and science and technology progress. It is headquartered in Xicheng District, Beijing, with branch institutes all over mainland China. It has also created hundreds of commercial enterprises, Lenovo being one of the most famous.

Massive Neutron Star Has a Strange Heart

“At the end of a star’s life, nuclear fusion ceases, and the resulting pressure is no longer sufficient to counteract the gravitational force. This collapse can lead to the formation of neutron stars, which are composed of the densest …

Researchers Discover Twisted Fields Around Mysterious Fast Radio Burst

“Fast Radio Bursts (FRBs) are the brightest millisecond-duration cosmic explosions in radio bands. Their unknown origin poses challenges for astronomy as well as physics. The Commensal Radio Astronomy FAST Survey (CRAFTS), a key program of the Five-hundred-meter Spherical radio Telescope …

3D-printed Polymer Substrate Coated with Photocatalytic Film Developed for Efficient Water Purification

“A research team led by Prof. ZHANG Dun from the Institute of Oceanology of the Chinese Academy of Sciences (IOCAS) has developed a novel in-situ growing bismuth oxyiodide (BiOI) film on 3D-printed polymer substrate through successive ion layer adsorption reaction …

China’s FAST Telescope Detects More Than 740 Pulsars

“Scientists have identified over 740 pulsars since October 2017 with the help of the 500-meter Aperture Spherical Radio Telescope (FAST), also dubbed as the “China Sky Eye.” Jiang Peng, chief engineer of FAST and researcher at the National Astronomical Observatories …

Tuning Local Coordination of Catalysts for Better Lithium-Sulfur Batteries

“A research team led by Prof. ZHU Qingshan from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences investigated the electronic structure transition from NiAs- to MnP- type CoPxS1-x compounds and how the transition influences catalytic activity …

New Strategy Proposed for Ultra-long Cycle Lithium-ion Battery
