How this score is calculated

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.

Abstract

A new algorithm is suggested for the calculation of energies and fractions of adsorption sites of different kinds from adsorption isotherms. The method is recommended for the investigation of crystalline surfaces when the number of distinguishable adsorption sites is not too large (≃1−5). The algorithm was applied in the treatment of the adsorption isotherm of nitrogen on the surface of maximally hydroxylated silica at 78 K. The procedure, which allows one to calculate the isosteric heat of adsorption with a correction for effects of multilayer adsorption, is used for calculation of the energies of adsorption.
