China’s Tianwen-1 probe radar has revealed the shallow stratification of the Utopia Planitia on Mars, providing crucial evidence for understanding the geological evolution and environmental and climate changes on Mars.

2. FAST Observatory Captures Active and Recurring Fast Radio Bursts

FAST (Five-hundred-meter Aperture Spherical Radio Telescope) has precisely characterized active repeating fast radio bursts, laying the observational foundation for ultimately revealing their origins. Fast radio bursts (FRBs) are the most intense explosions in the cosmic radio wave spectrum, with unknown origins, and are one of the major hot topics in astronomy.

3. New Technology Enables Hydrogen Production from Seawater via Direct Electrolysis

The principle and technical prototype

Research on a new principle for direct seawater electrolysis for hydrogen production has laid the foundation for solving long-standing technical problems in this field for both the scientific community and industry. The side reactions and corrosion caused by the complex components of seawater have always been major challenges for directly producing hydrogen through seawater electrolysis.

4. Mutation Characteristics and Immune Escape Mechanisms of SARS-CoV-2 Discovered

Prediction of the mutation sites in the receptor binding domain of the novel coronavirus that mediate immune escape.

The study has revealed the mutation characteristics and immune escape mechanisms of the new coronavirus, providing scientific guidance for vaccine development and precise treatment.

5. Design and fabrication of bifacial all-perovskite tandem solar cells.

The achievement of efficient all-perovskite stacked solar cells and modules provides new directions for the development of high-efficiency and low-cost solar cells.

6. Elemental electrical switch enabling phase segregation–free operation offers High-Performance Storage Solutions

Femtosecond laser-induced micro-nanostructure formation in complex systems has discovered new mechanisms, laying the foundation for the application of perovskite nanocrystals in photonics and optical devices.

10. Discovery of segmented Fermi surface induced by Cooper pair momentum

Experimental research on the “segmented Fermi surface” in the superconducting state has paved the way for new methods of controlling physical states and constructing novel topological superconductors. Artificial control of the Fermi surface is the most important approach to material property regulation.

These breakthroughs are pushing the boundaries of human knowledge and will undoubtedly have a significant impact on science and technology. Overall, the future looks bright with these significant breakthroughs, and we can eagerly anticipate what further advances may come in 2023 and beyond.
