嫦娥六号月球样品中首次发现天然单壁碳纳米管与石墨碳

Group 1 - The research team from Jilin University has discovered and confirmed the existence of naturally formed single-walled carbon nanotubes and graphite carbon in lunar soil samples from the Chang'e 6 mission, marking a significant advancement in understanding lunar geological activity [1][2] - The study utilized various microscopic and spectroscopic techniques to systematically characterize the lunar samples, revealing the formation and evolution processes of graphite carbon and confirming the presence of single-walled carbon nanotubes without artificial intervention [1] - The formation of these carbon nanotubes is believed to be closely related to multiple factors such as micro-meteorite impacts, volcanic activity, and solar wind irradiation, showcasing nature's ability to synthesize key materials under extreme conditions [1] Group 2 - The research indicates that the carbon structure in the Chang'e 6 samples exhibits more pronounced defect characteristics compared to the Chang'e 5 samples, likely due to a more intense history of micro-meteorite impacts on the lunar far side [1] - This finding reveals a new asymmetry in the material composition and evolutionary processes between the lunar near side and far side, contributing to the understanding of the moon's evolutionary history [1]
