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

Methods for the synthesis of nanoparticles (NPs) of zinc oxide in an aqueous-alcohol medium are described. Using scanning electron microscopy (SEM), it is shown that NPs with a size of 5–49 nm are formed. Optimal conditions for the treatment of cellulose materials with aqueous solutions of zinc-oxide NPs are developed. SEM studies confirm the presence of zinc-oxide NPs on the surface of cellulose materials, which are rather unevenly distributed. Antimicrobial activity is assessed by the degree of inhibition of bacterial growth ( Escherichia coli ) on materials treated with zinc-oxide NPs compared to the control samples. Cellulose materials modified with zinc oxide NPs are shown to have antibacterial activity against bacteria and molds.
