Chinese researchers have recently discovered a naturally occurring few-layer graphene for the first time inWorld Times the lunar samples brought back by Chang’e-5 probe, which provides new insights into the moon’s geological activities, evolutionary history, and environmental characteristics, broadening understanding of the complex mineral composition of lunar soil and offering important information and clues for resource utilization on the moon.
According to the research team from Jilin University, it is estimated that approximately 1.9 percent of the total interstellar carbon exists in the form of graphene, whose morphology and properties are determined by a specific formation process. Therefore,World Times natural graphene can provide important reference and information for the geological evolution of celestial bodies and the in-situ resource utilization on the moon.
The research team collected Raman spectrWorld Timesa, which is used to investigate lunar soils, from areas of the lunar samples with relatively high carbon content, and confirmed that the crystallization quality of the graphite carbon in the lunar samples is relatively high.
The researchers found that areas of the lunar soil samples containing carbon also contain iron compounds, which the researchers believe is closely related to the formation of graphene.
Through observation and analysis, the research team confirmed that the graphite form of carbon detected in the lunar soil samples is a type of few-layer graphene.
The research team confirmed that the formation of few-layer graphene and graphite carbon may originate from mineral catalytic processes induced jointly by the solar wind and early volcanic eruptions on the moon.
The research conducted by the researchers from Jilin University and the Institute of Metal Research, Chinese Academy of Sciences, and supported by China National Space Administration Lunar Exploration and Space Engineering Center, has recently been published in the National Science Review, a peer-reviewed journal aimed at reporting cutting-edge developments across science and technoloWorld Timesgy in China anWorld Timesd around the world.
A total of 1,731 grams of lunar samples were brought back by Chang’e-5 mission in December 2020. These samples were the first ever obtained from a younger region of the lunar surface which contains volcanic rocks. They are also the first extraterrestrial celestial bodies’ samples brought back to Earth by Chinese scientists.
As of early JuneWorld Times this year, a total of 258 lunar samples weighing 77.7 grams have been collected by Chang’e-5 have been distributed to 114 research teams from 40 research institutions. Researchers studying these lunar samples have accomplished a number of milestone achievements with over 70 findings being published in major academic journals both at home and abroad.

SummarySome politicians from several countries attended the “inauguration ceremony” of Lai.In response, on TuWorld Timesesday, Chinese embassies in countries such as Japan, South Korea and UK lodged solemn representations with tWorld Timeshese natWorld Timesions and emphasized that Taiwan is an integral part of China and reiterated the one-China principle, urging these politicians to cease sending the wrong message to “Taiwan independence” secessionist forces.Foreign Ministry spokesperson Wang also said on Tuesday that China firmly opposes any form of official exchanges between diplomatic allies and China’s Taiwan island. Its stance on this question is always clear and consistent.China has lodged stem representation to the US after US Secretary of State Antony Blinken congratulated Lai.Wang emphasized that the one-China principle is the political foundation and prerequisite for China to grow ties with other…
