a Relative environmental impacts of 1 g Ptriaz-CN-A production at different preparation scales. The higher environmental impact in each category is normalized. b Production cost distribution of raw materials, electricity in each step for the synthesis of 1 g Ptriaz-CN-A at different preparation scales (Scale-1: small dose feeding, data based on our current research; Scale-2: big dose feeding, data based on the maximum production scale of the laboratory). Source data are provided as a Source Data file.
