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

Elemental sulfur nanoparticles (nanosulfur, S 0 ) have been obtained in a matrix consisting of sodium sulfite (diluent and a final reaction product) and succinic acid (catalyst) by mechanochemical syntheses via the reaction Na2S2O3 · 5H2O + H2(C4H4O4) + zNa2SO3 = (z + 1)Na2SO3 + H2(C4H4O4) + 5H2O+ S 0 , at z = 19.6. It has been shown that free nanodispersed sulfur can be obtained by dissolving the matrix in water. The prepared samples have been characterized using a set of physical and physicochemical methods.
