CARBON FUNCTIONAL MATERIALS DATABASE (cfms_db) - Version 1.0

The cfms_db_1.csv file is in version 1.0 and it was obtained from the processsing of 10,975 articles which contained the terms "biochar" or "hydrochar" either in the title, abstract or keywords. The title of each article indexed in the cfms_db_1.csv is detailed in the file filename_id_1.csv.

The carbon functional materials database (cfms_db) was generated from the processing of scientific articles by the a.RIX engine. Details on the use of the a.RIX engine is presented in:
