"Comprehensive Experimental Research Device Based on Adjustable Extreme UV Coherent Light Source" (hereinafter referred to as Dalian Coherent Light Source) project has recently received good news - Jiang Ling, a researcher at the National Key Laboratory of Molecular Reaction Kinetics and Dalian Light Source Science Research Office, and Yang Xueming, an academician of the Chinese Academy of Sciences, cooperated with the Professor of , Li Jun, Research Group, using the independently developed neutral cluster infrared spectroscopy experimental method based on Dalian coherent light sources, multiple prism-shaped and cage-shaped structures were found in the heptamer of neutral water clusters like ice, in order to uncover the hydrogen bond network of liquid water to micro ice from liquid water to micro ice. The network evolution mechanism provides new ideas.
For Yang Xueming, who led the research and development of the device, the important discoveries of the team members are worth celebrating, and the continuous output of heavyweight results of Dalian's coherent light sources is even more exciting.
As the director of the National Key Laboratory of Molecular Reaction Dynamics, Yang Xueming has traveled in the beloved academic world for decades, and has achieved a series of major achievements in the field of international molecular reaction dynamics , which has enhanced my country's international status in this field. What makes Yang Xueming even more proud is that he promoted and led the design and development of many original scientific research instruments, which greatly improved the level of scientific research instruments in my country.
"I am a very lucky person. I have been doing things I particularly like throughout my life, and these things have made some contributions to the country. "Yang Xueming sighed.
started from scratch and returned to China to join Dalian Institute of Chemical Physics
The turning point of Yang Xueming's academic career occurred in 2001.
Previously, after obtaining a doctorate degree from the University of California, Santa Barbara, Yang Xueming worked for several years at Princeton University and the University of California, Berkeley, and then went to Taiwan at the invitation of Li Yuanzhe, the Nobel Prize winner in Chemistry. Working in the Institute of Subschool and Molecular Sciences, from an associate researcher to a lifelong researcher, it lasted for 6 years.
In 2001, Yang Xueming visited Dalian Institute of Chemical Physics, Chinese Academy of Sciences (hereinafter referred to as Dalian Institute of Chemical Physics, Chinese Academy of Sciences). Back at his alma mater where he was pursuing a master's degree, Yang Xueming was filled with emotion. His heart that wanted to return to China to do something more passionate.
At that time, due to his outstanding academic achievements, Yang Xueming was already famous in the industry. He was on a business trip abroad, and As director of Dalian Institute of Chemical Physics, Chinese Academy of Sciences, Bao Xin and learned about his visit, and immediately called him to ask if he was interested in working in the institute.
Yang Xueming accepted the invitation happily. This reply means that everything must start from scratch. The original thriving scientific research career will be interrupted, and the scientific instruments that have been hard-working cannot be relocated and accompanied, and a scientific research team must be formed from scratch... Yang Xueming knows very well what kind of hardships he will face when he is over forty years.
, but he is still very firm. After
returned to China, Yang Xueming served as director of the State Key Laboratory of Molecular Reaction Kinetics, Dalian Institute of Chemical Physics, Chinese Academy of Sciences. The Dalian Institute of Chemical Physics, Chinese Academy of Sciences opened a "green channel" for it, allocated 10 million yuan of start-up funds to Yang Xueming, and provided him with a free and superior scientific research environment as much as possible. After
joined the company, Yang Xueming's first work was to study the resonant state of fluorine hydrogenation reaction. "The fluorine hydrogen system is one of the most important research contents in the field of chemical lasers. "Yang Xueming said that fortunately, he quickly achieved a series of important achievements in this field. The research work led by Yang Xueming was selected as one of the "Top Ten Science and Technology Progress in China" for two consecutive years. In just a few years, the team he led became an internationally renowned research team in the field of chemical reaction " resonance state ", and the National Key Laboratory of Molecular Reaction Dynamics has also become an internationally influential research base in this field.
Looking back on the past, Yang Xueming said emotionally: "Nothing is more important than the value of his own achievements to national scientific research."
has a lofty position. He led the research and development of high-end scientific research instruments. In addition to producing a series of major achievements, what makes Yang Xueming even more proud are scientific research instruments designed and developed independently.
These instruments are Yang Xueming's most powerful "weapons" for the academic battlefield and are the tools for him to dialogue with his beloved chemical world. Over the past 20 years, it is precisely because of the self-developed and original internationally leading scientific instruments that Yang Xueming has achieved highly-respected research results in the research of chemical reaction dynamics .
"My job is to study chemical reactions using experimental physics methods, and the level of research work depends on the design of experimental ideas and the development of special instruments and equipment. "Yang Xueming said, "In most contemporary scientific fields, advanced scientific instruments play a very important role, and scientific instruments are also an important reflection of the national scientific and technological hard power level. "
The national major scientific research instrument and equipment special project with a total budget of 140 million yuan, led by Yang Xueming, passed the acceptance in 2018.
This is my country's first large-scale free electron laser user device, and it is also the only free electron laser device operating in the extreme ultraviolet band in the world. It is the brightest extreme ultraviolet light source in the world.
The extreme ultraviolet light source is the most effective light source for excitation and soft ionization of molecules, and it helps scientists conduct a series of major scientific issues at the level of atom molecules. Developing a high-bright extreme ultraviolet free electron laser light source is a dream that Yang Xueming had when doing postdoctoral research at the University of California, Berkeley.
"This is also one of the things I want to do most when I returned to the Dalian Institute of Chemical Physics, Chinese Academy of Sciences. Fortunately, I received strong support from Natural Science Foundation of China . This dream was finally realized. "Yang Xueming said that the National Science Foundation of China funded the research and development of relatively large scientific research instruments and equipment that year, which reflected its courage and foresight. Using this advanced light source, scientific researchers have achieved a series of important research results in the experimental research carried out.
At present, Yang Xueming is actively promoting the development of my country's new generation of high-frequency free electron laser devices, and strives to promote the construction of Shenzhen's planned energy X-ray free electron laser and Dalian extreme ultraviolet free electron laser projects, and provide scientific researchers with the world's most advanced extreme ultraviolet and soft X-ray light sources.
is just like the construction of Dalian's coherent light sources back then. Yang Xueming knows that the construction of high-frequency X-ray free electron laser devices is also a very difficult thing. "But we just want to do something that others have not done before. "Yang Xueming said.
"In the past few decades, our country has made great progress in many technological fields, but the foundation for scientific research and development is still relatively weak. The scientific research field is subject to many aspects because we do not have enough strength in the research and development of high-end scientific research instruments. "As the representative of National People's Congress , Yang Xueming was in different occasions to develop high-end scientific research instruments.
followed interests and devoted himself to the field of chemistry research
Yang Xueming's research content is atomic and molecular chemical reaction process. Atoms, molecules... This tiny but endless world fascinated him.
and many well-known scientists have developed a strong interest in science due to various opportunities since childhood. Yang Xueming admitted that he did not have a preliminary understanding of science until he entered university.
"Although I was very interested in chemistry when I was in junior high school, it was mainly because I met a good teacher and had little to do with the subject itself. "Yang Xueming said with a smile.
Although I studied physics in college, my strong interest in chemistry in middle school ultimately brought Yang Xueming to the world of chemistry.
" When I took the postgraduate entrance examination, I chose the direction of chemistry very firmly. "Yang Xueming said, "If a person is not interested in a direction, it is difficult for him to truly have a good development in scientific research. Interest is the internal driving force for engaging in scientific research. "
There is no way to go in vain in life." The background in physics in college later became my advantage in chemical dynamics research. "Yang Xueming said.
personal experience made him deeply aware of the importance of being a good teacher and the urgency of promoting cross-integration of disciplines at a time when major changes in the scientific research paradigm have taken place. In November 2017, Yang Xueming had a new identity - the dean of the School of Science, Southern University of Science and Technology.
"I am very fortunate to be at the forefront of scientific research, and I am also very excited to have the opportunity to participate in the development and construction of the School of Science and Technology of Southern University of Science and Technology. I hope I can do something for the reform and development of higher education in China, especially in the cross-integration of disciplines." Yang Xueming said.
Although the business is complicated now, Yang Xueming still leaves at least half of his working time for scientific research.
"What makes me feel the happiest is probably thinking about scientific issues in the laboratory all day long and discussing with students." Yang Xueming said, "For me, scientific research work is like southerners who eat rice every meal. If they don't eat a meal, it seems like something is missing." (Reporter Cao Xiuying)
