It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
The hydrogenation of a light fraction of primary coal tar was carried out in the presence of ß-FeOOH, Fe 2 O 3 , and Fe 3 O 4 nanocatalysts in a temperature range from 298 to 1000 K. Phenols were removed by extraction with an alcoholic solution. The thermodynamic functions, such as heat capacity, entropy, enthalpy, and Gibbs energy, of the fraction of primary coal tar and a dephenolized fraction of the primary coal tar were calculated.
