On February 10, mainland scholars published 6 papers in Nature! Five of them are from institutions affiliated with the Chinese Academy of Sciences.
What's more, 3 of them are from the same university, the University of Science and Technology of China, and just last week, the team of the University of Science and Technology of China just appeared in the journal Science.
1. Pan Jianwei and Zhao Bo of the University of Science and Technology of China cooperated with the Bai Chunli Group of the Institute of Chemistry of the Chinese Academy of Sciences, and the relevant results were published in Nature under the title of "Evidence for the association of triatomic molecules in ultracold 23Na40K + 40K mixtures".
The research team synthesized triatomic molecules for the first time in an ultra-cold mixture of atoms and molecules, an important step towards quantum simulations based on ultracold atoms and molecules and the study of ultracold quantum chemistry.

It is worth mentioning that only a week ago, Pan Jianwei, Yao Xingcan, Chen Yuao, etc. cooperated with Australian scientist Hu Hui to achieve research results that are "expected to become a milestone in the field of quantum simulation", which was published in the journal Science, which can be described as the top journal "get soft".
In 2020, the team of academician Pan Jianwei of the University of Science and Technology of China cooperated with the Chinese Academy of Sciences to build a prototype of the "Nine Chapters" quantum computer, making China the second country in the world to achieve "quantum superiority".
Up to now, their academic achievements on "quantum communication" and "quantum simulation" that have attracted the world's attention are still endless, and it can be said that the status of the University of Science and Technology of China is irreplaceable in undertaking major national basic scientific research projects and key "card neck" technical problems.
2. The scientific research team composed of Chen Xianhui, Wu Tao and Wang Zhenyu of the Hefei National Research Center for Microscale Physical Sciences of the University of Science and Technology of China recently discovered a new type of electron lentis in the cage superconductor CsV3Sb5, and the relevant results were published in Nature.
This finding not only provides important experimental evidence for understanding the abnormal competition between charge density waves and superconductivity in cage-structured superconductors, but also provides a new research direction for further studying the interleaved sequences in associated electronic systems that are closely related to unconventional superconductivity.

3. Professor Liu Haiyan and Associate Professor Chen Quan of the Faculty of Life Sciences and Medicine of the University of Science and Technology of China have opened up a new protein design route based on the principle of data drive, and the relevant results were published on Nature.
In the frontier technology field of protein design, the original innovation of key core technologies has been realized, laying a solid foundation for the design of functional proteins such as industrial enzymes, biomaterials, and biomedical proteins.

4. Gao Caixia and Xiao Jun, researchers of the Institute of Genetics of the Chinese Academy of Sciences, and Qiu Jinlong, researchers of the Institute of Microbiology of the Chinese Academy of Sciences, published a research paper entitled "Genome-edited powdery mildew resistance in wheat without growth penalties" in Nature, which elucidated the molecular mechanism of the new mlo mutant of wheat that is both resistant to powdery mildew and high yield And through genome editing, the MLO-related genetic alleles of the susceptible gene MLO are accurately manipulated in the main wheat varieties, and the new germplasm with broad spectrum anti-powdery mildew and high yield and high quality is quickly obtained. This study provides a new path for the practical application of disease-susceptibility genes in disease resistance breeding.
5. The team of Li Heping, He Yu and Sun Shichuan, researchers of the High Pressure Room of the Institute of Geochemistry of the Chinese Academy of Sciences, cooperated with Mao Heguang, a foreign academician of the Chinese Academy of Sciences and director of the Beijing High Pressure Science Center, Duck Young Kim, and Dr. Bo Gyu Jang to perform computational simulations of the properties of various ferroalloys (at the temperature and pressure of the Earth's core), and found that the hexagonal phase (hcp) Fe-H, Fe-C and Fe-O alloys were transformed into superionic states under the temperature pressure of the core. Superionic hcp-Fe alloys and their seismic velocities in Earth's inner core" was published in the main issue of Nature on February 10, 2022.
6. Yong Yang, City University of Hong Kong, D. Lee, University of Hong Kong J. Srolovitz and Chun-Wei Pao of Taipei University, published a research paper in Nature online titled "A highly distorted ultraelastic chemically complex Elinvar alloy", reporting a chemically complex alloy that exhibits high elastic strain limits and very low internal friction at room temperature.
More interestingly, the alloy maintains a nearly constant modulus of elasticity between room temperature and 627 degrees Celsius (900° Kelvin), which is unmatched by existing alloys reported so far.
