Data confidence 70 medium
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 deals with the problem of the appearance of the grain boundary nanopores in polycrystalline materials of the parquet type. The mechanism of their formation is proposed, as well as appropriate modeling is carried out, which allowed to establish the condition for the appearance of nanopore instead of stress concentrator. These studies are important for understanding the nature of the grain boundary defects in polycrystalline materials for their applications in photovoltaic energy converters.
