Core Viewpoint - The ninth batch of scientific experiment samples from the Chinese space station has successfully returned, enabling scientists to conduct further research on various scientific fields, including life sciences, materials science, and combustion [1][3][5]. Group 1: Life Sciences - The returned life science samples include 9 types of experiments involving mice, zebrafish, and other organisms, weighing approximately 46.67 kilograms in total [3][5]. - Researchers will analyze the behavior and physiological biochemical indicators of the returned mice to understand their stress responses and adaptive changes in a space environment, providing scientific evidence for the effects of space on living organisms [3][5]. - Further biological analyses, such as transcriptome sequencing and proteomics, will be conducted on the life cell samples to explore the impact of microgravity on biological mechanisms and potential intervention targets for related diseases [5][6]. Group 2: Materials Science - The materials science samples include tungsten-hafnium alloys, soft magnetic materials, and relaxor ferroelectric single crystals, which will be tested for their morphology, chemical composition, and distribution differences [5][6]. - The research aims to understand how gravity affects material growth, segregation, solidification defects, and performance, which will contribute to the development of high-performance materials for satellite communication and space exploration [5][6]. Group 3: Combustion Science - The combustion samples, including burners and soot collection plates, will be analyzed for the characteristics of flame-synthesized products and nano-carbon particle generation [6]. - The findings are expected to support the development of extraterrestrial nano-materials, new energy systems, space fire prevention technologies, and advanced functional nano-carbon materials [6].
