Süsinike

I’m not finding a reliable source for a topic specifically named “süsinike.” In Estonian, “süsinik” means carbon, and “süsinike” isn’t a standard term in common scientific or encyclopedic references. Could you clarify what you mean by “süsinike”? For example:

- Do you mean carbon (süsinik) or carbon compounds in general?

- Do you mean carbonic acid (süsinikhape) or carbon dioxide (süsinikdioksiid)?

- Is Süsinike a proper noun, place, organization, or a fictional concept?

If you provide context, I can write a concise, neutral wiki-style article under 300 words. If you’d like, I can also draft a brief article on one of the interpreted topics above.
