“Spatterned Neutron Source National Major Science and TechnologyBabaylanInfrastructure”
The first national large scientific facility in the Pearl River Delta, a “weapon” for scientific research and intelligent manufacturing
Chen Hesheng, an academician of the Chinese Academy of Sciences and commander-in-chief of the Spatterned Neutron Source Engineering Command, introduced that the Spattered Neutron Source is like a “super microscope” and is an ideal probe for studying the microstructure of material materials. In January 2006, the Chinese Academy of Sciences launched a prefabricated research project for spalling neutron sources. In the same year, the project was chosen to settle in Dalang Town, Dongguan. By October 2011, the China Komiks spalling neutron source device with a total investment of approximately RMB 2.3 billion was laid in Dongguan, ending the history of no national large scientific equipment in the Pearl River Delta region.
In the autumn of 2017, China’s spall neutron sources successfully obtained a neutron beam that was fully in line with expectations for the first time, and the debugging speed was far higher than that of foreign spall neutron sources. In March 2018, China Spallation Neutron Source passed the process test and appraisal organized by the Chinese Academy of Sciences. All performance indicators met or were better than the acceptance indicators. The engineering construction tasks were completed according to the indicators, according to the construction period and with high quality. The technology and comprehensive performance entered the list of similar international devices. The project has officially passed the national acceptance, filling the gap in the field of pulse neutron application in China, and is open to domestic and foreign users.
As of now, spalling neutron sources have completed about 700 user experimental projects, carried out major innovative research in many fields, and carried out residual stress and service performance detection of large-scale engineering components such as deep-sea submersibles, providing a key technical platform for the research and development of many high-performance structural materials urgently needed by the country.
China’s spallingBabaylanSubsources are the first major scientific and technological infrastructure in the Guangdong-Hong Kong-Macao Greater Bay Area. The most direct benefit of its construction is to bring research to scientific researchers, especially to provide unprecedented convenience for Hong Kong and Macao scientists to use spalling neutron sources. At the same time, the Greater Bay Area is a highland of advanced manufacturing in the country and has an urgent need for materials science research. The layout of spalling neutron sources in Dongguan is of great significance.
Chen Hesheng also revealed that the second phase of the spalling neutron source project was officially included in the major national scientific and technological infrastructure in the first half of 2021.In the construction of the “14th Five-Year Plan”, all preliminary preparations have been approved by relevant departments and are expected to officially start this year. The number of spectrometers in the future will increase to 20, covering all research fields of users. The power of accelerator target shooting and target stations will be increased from 100 kilowatts to 500 kilowatts. The equipment research capabilities will be greatly improved, which can greatly improve the accuracy and speed of experiments, measure smaller samples, study faster dynamic processes, meet the needs of more users at home and abroad, provide a more advanced research platform for cutting-edge scientific research, major national needs and national economic development, and make more contributions to achieving high-level scientific and technological self-reliance.

Part 1 Prize of Natural Science Award
Research on the stratigraphic structure of the Loess Plateau: Refreshing the understanding of the origin and migration history of ancient humans
This time I won the first prize of Natural Science AwardThe project “Age of the Loess Stratigraphy and Paleoenvironment and its Early Human Evolution in the Southern Loess Plateau” was led by the Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, and the results are sufficient to change the understanding of the traditional migration and diffusion patterns of ancient humans.
It is understood that this project belongs to the basic research of Quaternary geology. The origin and evolution of human beings are major scientific issues in the study of Quaternary and “paleoglobal changes”. At present, high-resolution environmental evolution sequences of paleozoos, paleoplants and even archaeobacteria have been established. However, the research on “high-resolution environmental evolution sequences” of ancient human beings is very rare. The biggest difficulty is that a good sedimentary sequence and activity place has not been found. Zhu Zhaoyu, a researcher at the Guangzhou Institute of Geochemistry, Chinese Academy of Sciences and the first completed project, introduced that Lantian, Shaanxi in the southern part of the Loess Plateau, has 37 loess-paleosoil strata sequences, recording the 37 ice-interglacial climatic cyclones of Komiks during the Quaternary period, and several ancient human fossils and stone sites in Cinema have been discovered. From 2001 to 2018, Zhu Zhaoyu took the lead in joining a research team composed of more than ten scientific research and university scholars at home and abroad to conduct cross-cooperation surveys and research in the Lantian area, and accumulated thousands of first-hand data.
The research work independently discovered the ancient human stone tools in the loess layer 2.12 million years ago. Using a variety of technical methods and high-resolution paleomagnetic dating, two most important paleomagnetic events – the Oduwee and Reunion positive polarity sub-phase, were detected, and the stone tools in the oldest loess formation were determined to date by 2.12 million years ago, 270,000 years earlier than the internationally recognized Demanisi stone tools (1.85 million years) in Georgia, which is the internationally recognized internationally. This new discovery makes Lantian Shangchen Village one of the oldest human activity sites known outside Africa to date, rewriting the history of early human origins and migrations.
The study also re-determined the age of the skull of Gongwangling from 1.15 million years ago to 1.63 million years ago, making it the second oldest skull fossil known beyond Africa to date. It determined that Homo erectus had appeared in East Asia at least 1.6 million years ago, changing the understanding of the traditional ancient human migration and diffusion patterns. In addition, the team independently discovered 23 Paleolithic layers from 450,000 to 2.12 million years in Shangchen Village, Lantian, and used various ancient ring environment indicators to reveal the evolutionary characteristics of the living environment of ancient humans for a long time. This is CinemaThe world’s unique new discoveries with long scale, multi-stage and high frequency are currently known, which have laid the foundation for making Lantian a global time mark and landmark. At the same time, it has opened a breakthrough in the weak links of “high-resolution evolutionary sequences of ancient humans and their living environment” in the study of “paleoglobal changes”.
The project results have won the “Top Ten Progress in Chinese Science in 2018″ in the country, and are also the only ones in Guangdong Province so far. href=”https://comicmov.com/”>BabaylanThe only geological scientific achievement obtained by the first author of the first unit, and was rated as the “most important discovery in the field of human evolution in the past decade (2010-2019).
Mesenchymal stem cell technology: providing new therapeutic strategies for difficult and serious diseases
Series of “Mesenchymal stem cell functional characteristics, therapeutic mechanism and clinical transformation completed by Sun Yat-sen University’s Stem Cell and Regenerative Medicine Innovation Platform “The project won the first prize in the Natural Science Award.
Xiang Peng, head of the Stem Cell and Regenerative Medicine Innovation Platform of Sun Yat-sen University and the first completed project, introduced that stem cell technology is currently the need for the treatment of major diseases. Regenerative medicine with stem cells as the core is expected to become the third disease treatment method after drug treatment and surgical treatment, providing new treatment strategies for major refractory diseases. After nearly 20 years of research, the research team has achieved a series of breakthrough results in the functional characteristics, treatment mechanism and clinical transformation of mesenchymal stem cells.
Xiang Peng said that almost every organ and tissue in the body has mesenchymal stem cells (MSCs). This cell is not only widely sourced, but also easily isolated and amplified. It can differentiate multiple times and participate in hematopoietic support, immune regulation, tissue damage repair, etc., and has a broad clinical application scenario. However, as of now, China and the United States have not approved any MSC product to be marketed. The reason is that MSC clinical transformation still faces a series of bottlenecks that need to be solved urgently.
In response to the bottleneck, the project team focused on how to “discover functional subgroups and reveal the The team has carried out cooperative research on scientific issues such as the mechanism of treatment and precise selection of indications, and has made important breakthroughs.
The team took bone marrow MSC as the entry point to deeply analyze the mode of action of MSC in different pathological microenvironments, revealing the multi-dimensional and multi-target immune regulation mechanism of MSC, and providing a scientific basis for the clinical precise selection of MSC indications. On this basis, the team accurately selected indications and took the lead in conducting clinical clinical research on MSC treatment of transplant rejection diseases in the world, confirming the safety of MSC in the treatment of chronic graft-versus-host disease. href=”https://comicmov.com/”>Komiks is effective and reveals for the first time that regulatory B cells are the key targets for MSC treatment. Based on an in-depth understanding of MSC, the team took the lead in formulating the first domestic group standard for “Human Mesenchymal Stem Cells” and the first domestic allogeneic human bone marrow M developed.SC injection has been approved by the National Medical Products Administration for Drug Clinical Trials, and is expected to achieve breakthrough treatment for major refractory diseases.
