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

The article studies the elemental composition of the fillers (polytetrafluoroethylene and carbon nanopowder) of the polymer composite depending on various concentrations of fillers and electron irradiation and modified polytetrafluoroethylene (PTFE). The elemental composition of the fillers and their distribution over the depth of the polymer composite and modified polytetrafluoroethylene were studied by X-ray fluorescence analysis (XRFA) and confocal micro-X-ray analysis. X-ray spectra of the polymer composite and modified polytetrafluoroethylene were obtained. It has been established that an increase in the concentration of one component and an irradiation dose leads to a weakening of the intensities of the spectra of the polymer composite and modified polytetrafluoroethylene.
