With 13C and carbon source as the core, 13C and carbon source are in a key position in the composition of matter. 13C has unique nuclide characteristics, and is an essential tool for exploring the mysteries of microanalysis in many researches. Its trace on the logo shows the transition and rheology of matter, which is like a guiding star in the dark night, allowing researchers to glimpse the trajectory of matter.

Carbon source is the foundation of all living things. All kinds of organisms, from microscopic bacteria and algae to huge living things, rely on carbon sources for energy and quality for their growth and reproduction. The types of carbon sources are different, either organic glyoxal or inorganic carbonic acid, each of which is suitable for different environments and promotes different biochemical processes.

Researching 13C and carbon sources is like holding a key lock, which can unlock the mystery of biological metabolism and ecological cycle. In industrial production, using 13C as the standard to observe the conversion and utilization of carbon sources can help the improvement of technology, improve production and quality; in the ecological field, the circulation of carbon sources and the distribution of 13C can reveal the maintenance and change of ecological balance, providing the most important evidence for environmental conservation and resource planning. Therefore, studying 13C and carbon sources in detail is of great benefit to all things scientific, and it is also an important way to explore nature and serve the world.
