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 structure and the morphology of the nickel nanopowders synthesized by an electric explosion of a metallic wire are comprehensively studied. The results of scanning and transmission electron microscopies show that the nickel nanoclusters have a spherical shape with an average diameter of 50 nm. An analysis of X-ray diffraction patterns demonstrates that the lattice parameter of the electric explosion nanopowder particles is larger than the standard parameter. The results of computer experiments agree well with the conclusions drawn from X-ray diffraction data. However, the causes of the lattice distortion in the nickel nanoclusters are still debatable.
