In the eyes of laymen, chemistry always deals with colorful bottles and jars. When you see the term "theory and computational chemistry", you feel like you want to open a profound book of heaven. This is exactly the teaching and research field that Academician of the Chinese Academy of Sciences and Vice President of the Chinese University of Science and Technology Yang Jinlong has been engaged in for a long time.
"Chemistry is a science that studies the changes of matter, and its main purpose is to create matter and control the transformation of matter. The transformation of matter has its own internal laws, which are the research content of theoretical chemistry. Because the material world is rich and complex, relying on analytical expression alone is far from enough, so mathematical operations must be applied and combined with computational science, which is computational chemistry." Yang Jinlong explained in simple words, "In short, theory and computational chemistry are a basic discipline of chemistry, mainly providing theoretical predictions and experimental explanations."
UST China University of Science and Technology single molecule science team is an internationally renowned single molecule team, and Yang Jinlong is one of the leaders of the team. This stage for studying microscopic world is exactly where Yang Jinlong "started".
In 2001, a single molecule image that can distinguish carbon 60 chemical bonds was taken, and the world successfully directly observed the internal structure of the molecule for the first time; in 2005, a "single-molecular surgery" was performed on the cobalt phthalocyanine molecule adsorbed on the metal surface, and the world realized single-molecular spin state control for the first time; in 2013, the spatial imaging resolution with chemical recognition ability was increased to 0.5 nanometers, and the world realized sub-nanometer-resolved single-molecular optical Raman imaging for the first time... Over the past 20 years, Yang Jinlong has cooperated with colleagues to continuously make major breakthroughs in the field of single-molecular science, and his achievements have been selected as the "Top Ten Science and Technology Progress in China" selected by academicians of the two academies.
"Integrated circuit devices have now reached a scale of several nanometers, but from the perspective of quantum mechanics , the ultimate limit of these devices is a single molecule or even a single atom . For more than 20 years, we have been at the forefront of the world in the field of single molecule device research." Yang Jinlong said that he hopes that one day in the future, the devices in integrated circuits can really reach the level of single molecules and single atoms.
In May 2021, General Secretary Xi Jinping mentioned at the 10th National Congress of the Academicians of the Chinese Association for Science and Technology in recent years at the Academicians of the Chinese Academy of Sciences and Technology , at the 10th National Congress of the my country Association for Science and Technology in the past, including the "Shenwei, Taihu Light" supercomputer has achieved ten million core parallel first-principle computing simulation for the first time. Yang Jinlong’s research team is the main accomplisher of this major research result.
"Shenwei·Taihu Light" supercomputer system is my country and the world's first supercomputer system with theoretical floating-point computing power reaching the order of 1 billion times. "Only good hardware and good software can we do good scientific research. We effectively apply the independently developed software on the best computers in the world." Yang Jinlong said that the combination of the theory of the University of Science and Technology of China and the low-scale theoretical algorithms of computing chemistry and the advantages of domestic high-performance parallel computing software and hardware allows "Shenwei Taihu Light " to fully utilize its powerful computing capabilities.
The undergraduate major is physics, and has achieved a series of major achievements in the field of single-molecular chemistry. Now Yang Jinlong has entered the palace of computing science again. "Most major breakthroughs in scientific research occur at the forefront of interdisciplinary disciplines. From physics to chemistry to computers, this is my growth trajectory." Yang Jinlong said that he encouraged students to carry out interdisciplinary research on . Some of the students recruited have a foundation in physics and chemistry, some have a computer foundation, and some have obtained double degree .
"China's development cannot be separated from technological innovation, and the younger generation of scientific and technological workers have made great achievements. I hope they will make more and greater breakthroughs at the forefront of disciplines and in the field of source innovation!" Yang Jinlong has high hopes for students.
