From the National Astronomical Observatories, CAS

Using the data from LAMOST, the research team has undertaken systematic inquiries into the cutting-edge field of the early formation and evolution of the Milky Way, and achieved original breakthroughs. The team identified the chemical signature of a pair-instability supernova (PISN) resulting from the evolution of a first-generation very massive star, opening up a new direction for the study of the Milky Way’s initial mass function at the massive end. The team also proposed a novel approach for identifying accretion remnants using stellar orbital parameters and unique chemical tags, and provided observational evidence of dwarf galaxies accreted by the Milky Way in orbital and chemical spaces, respectively. The team discovered that lithium-rich stars are primarily red clump stars that have undergone helium flashes, and proposed that helium flashes are a universal new mechanism for lithium production, which reshaped the theory of lithium formation and evolution. These research findings have unveiled key physical processes in the early formation and evolution of the Milky Way, having a significant impact on frontier research of the Milky Way.


Discovery of novel effects in metals at extremely-fine grain sizes

By LI Xiuyan, XU Wei, ZHANG Baobing and LUO Zhaoping

From the Institute of Metal Research, CAS

The research group has focused on the structures and properties of metals with extremely fine grains. Utilizing independently developed extreme deformation equipment and technology, they have refined the grains of various metals to below ten nanometers and discovered the spontaneous grain boundary relaxation, anomalous phase transformations and Schwarz crystal structure. Their discovery of Schwarz crystal structure reveals that, when the grains are small enough, the polycrystals evolve into a metastable state where the grain boundaries are three-dimensional minimal-interfaces, instead of transforming into amorphous. Schwarz crystal exhibits a strength in the vicinity of the theoretical value – a high-level stability close to the equilibrium melting point, and extremely low diffusion coefficients. Based on these effects, new superalloys, aluminum alloys, and wear-resistant rollers have been developed, and some of them have been applied in industry.

From the Institute of Geology and Geophysics, CAS, and the National Astronomical Observatories, CAS

The research group has carried out interdisciplinary studies on major frontier issues regarding Martian environment evolution, achieving significant breakthroughs in the research field of multi-scale aqueous activity on Mars. They developed innovative methods of weak-signal extraction and high-resolution imaging for planetary radar exploration. Using these methods, for the first time they revealed fine subsurface structural layering and lateral variations, uncovering a long history of aqueous activity and long-timescale environmental changes on Mars.

The group was also the first to discover key evidence of liquid water on the dune surface of Martian low-latitude regions, and revealed short-term environmental changes characterized by alternating aeolian and aqueous activities. These findings open up a new direction for studying aqueous activity on Martian dunes.

Furthermore, the group developed independently a high-precision Mars rover magnetometer and a novel data calibration method, achieving the first ground magnetic survey on Mars. Their findings show that significant magnetic field changes and the weak magnetic field are essential to maintain Martian long-term aqueous activity.

These achievements have refreshed our understanding of Martian aqueous activity and provide original insights into the long-term evolution of paleomagnetic field and paleoenvironment on Mars.
