国际上首次！我国科研团队又一重要发现

Core Viewpoint - The research team from Jilin University has made a significant discovery by identifying naturally formed single-walled carbon nanotubes and graphite carbon in lunar samples from the Chang'e 6 mission, providing critical data for understanding the Moon's evolutionary history [1][2]. Group 1 - The study utilized various microscopy and spectroscopy techniques to systematically characterize the lunar samples collected from the far side of the Moon, marking the first international confirmation of naturally occurring single-walled carbon nanotubes [1]. - The research indicates that the formation of these carbon nanotubes is closely related to multiple factors, including micro-meteorite impacts, volcanic activity, and solar wind irradiation, showcasing nature's ability to synthesize key materials under extreme conditions [1]. - A comparative study between the Chang'e 6 samples and those from the Chang'e 5 mission revealed that the carbon structures in the Chang'e 6 samples exhibit more pronounced defect characteristics, likely due to a more intense history of micro-meteorite impacts on the Moon's far side [2]. Group 2 - This discovery follows the previous finding of few-layer graphene in the Chang'e 5 lunar samples, highlighting a new asymmetry in the material composition and evolutionary processes between the Moon's near and far sides [2]. - The research findings have been published in the academic journal "Nano Letters," further contributing to the scientific understanding of lunar geology [2].
