Yang Xueming, winner of the Future Science Award for Material Science, Jamaica Sugar dating – “Do something that others can’t do”
“If you want to do a good job in experimental scientific research, you should first make good scientific instruments and master key technologies.” For more than 20 years, an academician of the Chinese Academy of Sciences and a researcher at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences Member Yang Xueming has been working hard to explore and move forward on the road of developing advanced scientific instruments. At the end of 2022, he was reminded of the development of a new generation of high-resolution and high-sensitivity molecular beam scientific instruments for state discrimination. He won the 2022 Future Science Award “Material Science Award” for his achievements in quantum resonance phenomena and geometric phase effects in chemical reactions. Jamaicans Escort
Yang Xueming
More than 20 years ago, Yang Xueming decided to return to work at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences. He still feels that this is the right choice!
In 1985, Yang Xueming obtained a master’s degree from the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and continued to study for a doctorate the next year. For many years since then, he has been engaged in scientific research work outside… In 2001, he received an invitation from the then director Bao Xinhe, and he accepted it with pleasure; at that time, he had just obtained the position of lifelong researcher at a research institute, and making this decision meant giving up the good work. many.
Self-developed instruments and obtained a series of scientific research results
After returning, Yang Xueming served as the director of the National Key Laboratory of Molecular Reaction Dynamics at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences; the institute provided him with a good scientific research environment, and Yang Xueming lived up to expectations, using self-developed, internationally leading methods with his team. The molecular beam science instrument has pushed experimental research on reaction scattering dynamics to a high level of full quantum state discrimination, and has made important system achievements in the study of chemical reaction quantum transition states and resonance state dynamics.The results are listed, which solves some internationally recognized difficulties in the field of reaction kinetics and contributes to the development of chemical reaction kinetics.
In addition to producing a series of results, Yang Xueming is proud of the scientific research instruments he independently designed and developed.
The first time Yang Xueming started making complex scientific instruments was when he was a postdoctoral fellow abroad. At that time, with the encouragement of his mentor, he spent a whole year working with the engineers in the laboratory to make the design drawings of the first set of complex instruments in his personal work life on the computer… He said: ” Scientific instruments play an increasingly important role in the development of modern scientific technology. In the research field I am engaged in, almost no important results have been obtained with off-the-shelf instruments. ”
Follow your hobbies and change the scientific research track
In 1962, Yang Xueming was born in a small village in Deqing, Zhejiang. In middle school, he was particularly interested in chemistry, but he failed in chemistry in the college entrance examination and was eventually admitted to the physics department of Zhejiang Normal University. “When I took the postgraduate entrance examination, I decisively chose the direction of chemistry.” Yang Xueming said.
In 1982, Yang Xueming was successfully admitted to the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, opening the door to chemical physics. His specialization in physics research background in college has become his advantage in the field of chemical kinetics research.
In 1985, after obtaining his master’s degree, Yang Xueming went abroad to study. Later, he came up with the idea of changing his scientific research track. “Before, I was doing research on molecular spectroscopy, but I didn’t find anything at that time. I was particularly interested in the direction, and then I started to turn to chemical kinetics research. This shift inspired me not to give up my past accumulation, but to make full use of it to explore new directions. ”
So, Yang Xueming began to try to learn how to use computers to help design advanced scientific instruments and use synchrotron radiation Using advanced light sources to study chemical kinetics, “I particularly like to do instrument design and find this direction very interesting. Drawing design drawings and then making the instrument you want gives me a sense of accomplishment.”
Find new tools and new methods to conduct unique research
Dalian Relevant Light Source, a major national scientific research instrument and equipment project spearheaded by Yang Xueming, passed the acceptance test in 2018. This is China’s first large-scale unfettered electronic laser user device and the brightest extreme ultraviolet light source in the world. He said: “The extreme ultraviolet light source is the most effective light source for excitation and soft ionization of molecules, which helps scientists conduct a series of studies at the atomic and molecular level.”
Development A high-brightness extreme ultraviolet untethered electron laser light source was Yang Xueming’s dream when he was doing postdoctoral research. Fortunately, with the strong support of the National Natural Science Foundation of China and the National Institute of Natural Science, this dream has come true!
At present, Yang Xueming is promoting the international new generation of high repetition frequency unfettered electronic laser equipment Jamaicans Sugardaddyequipment aims to provide scientific research workers with the world’s most advanced extreme ultraviolet and soft X-ray light sources. “We want to do something that others can’t do and make very unique research.” Yang Xueming said.
