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

A method was developed to prepare sulfur nanoparticles (nanosulfur) via reaction between sodium thiosulfate and sulfuric acid in the presence of water-soluble poly-N-vinylpyrrolidone (PVP) with different molecular weights. Polymeric hydrogel ointments were prepared from agar-agar, PVP, poly(ethylene glycol) solutions with virable concentrations of sodium thiosulfate and sulfuric acid. The ointment samples showed antibacterial and antifungal activities against Staphylococcus aureus, Escherichia coli and Candida guilliermondii.
