Chinese Academy of Sciences condensed physicists study or influence the energy revolution in the future

<

According to the report of Anhui Commercial Daily, in Hefei Science Island, there is the only domestic inflatable device that can be loaded with hydrogen. Prof. Eugene Gregorains from the University of Edinburgh in the United Kingdom presided over the high-pressure (200GPA) hydrogen at low temperature (6K). Experiments on helium and cesium and their mixtures have refreshed the current record of extreme conditions in laboratories in mainland China. The study will have a profound effect on people's understanding of basic material laws and future energy revolutions. Because of his significant contribution to the economic and social development of Hefei, Prof. Eugene received the first Hefei Friendship Award. In recent days, Zhang Yong, deputy director of the Bureau of Human Resources and Social Affairs of Hefei City, came to the Hefei Institute of Physical Chemistry of the Chinese Academy of Sciences to award Professor Eugene.

Study on Extreme Conditions on the Micrometer Scale

Professor Eugene, born in 1966, is an internationally renowned condensed matter experimental physicist. His research area is condensed matter physics. Since 2014, Prof. Eugene has collaborated with the Hefei Institute of Physical Sciences of the Chinese Academy of Sciences to conduct experimental research on the behavior of hydrogen and its isotopes, helium, and their mixtures under high pressure, filling the research gap of the scientific project in Mainland China.

Under the auspices of Prof. Eugene, Science Island built a high-pressure inflatable system that can be charged with hydrogen, making the Hefei Research Institute the first real unit in China to carry out experimental research on high-pressure hydrogen. He conducted experiments on hydrogen, helium and their mixtures under high pressure and low temperatures, setting a new record for extreme conditions in laboratories in mainland China. How extreme is this condition? According to reports, hydrogen, helium and their mixtures were tested at 200 GPA (20 billion atmospheres) at 6 K (minus 267 degrees Celsius).

The team led by Prof. Eugene also used diamond-to-top anvil technology to operate on a micron-scale platform to reach the pressure limit beyond the center of the earth, and obtained evidence of the existence of a fifth phase of hydrogen at high pressure (before the scientific community did not observe The fifth phase of hydrogen). This phase is thought to be a precursor to the atomic state of hydrogen in the theory predicted 80 years ago. “Hydrogen metal atom states may have superconductivity and superconductivity. This theoretical study will disrupt the future of power transmission.” said Ding Junfeng, a researcher at the Hefei Branch of the Chinese Academy of Sciences, and because the mass of the sun is 75%. Consisting of hydrogen and 25% helium, Professor Eugene’s research has also contributed to human exploration of the composition of planets.

Hefei colleagues are enthusiastic and diligent

After three years with Hefei, Professor Eugene felt that Hefei was very enthusiastic and his colleagues were very diligent. One thing that Eugene remembered was that once an experiment was done, it needed to be done at 12 o'clock in the afternoon from 6 pm. Professor Eugene asked his colleague to go to the lab at 12 o'clock in the evening to see the results of the experiment. The colleagues agreed to say nothing. . "This is impossible at the university where I used to teach." Eugene likes to run and run. Everyone who sees such a high nose will take the initiative to say hello. "Sometimes I can't read the street signs and can't read the names of products. Everyone is very warm, friendly and willing to help."

He spent more than four months each year in Hefei, and Professor Eugene enjoyed his scientific research in Hefei. "The platform here is even better than abroad. I have completed many experiments and achieved major breakthroughs in my field of research." Eugene said that he also likes Hefei's food, especially lamb.
