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

In the proposed research paper, we considered the pattern of formation of copper powders during the polarization of electrodes by transient currents. When a copper-titanium pair of electrodes is polarized with an industrial alternating current of 50 Hz in a solution of copper (II) sulfate, it is shown that copper powders with a high current yield are formed on the surface of the titanium electrode. Under optimum conditions, the current yield is 80%. The size of the formed copper powders is 0.5-2 µm. The analysis of the obtained oscillograms showed that when titanium is used in the circuit, the asymmetrical sinusoidal current flows.
