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

Formation of iodophors by interactions of poly(2-ethyl-2-oxazoline) and poly(N-vinylpyrrolidone) with molecular iodine dissolved in aqueous solutions with addition of potassium iodide and ethanol has been studied using a range of physicochemical techniques including UV–Vis spectroscopy, viscometry, dynamic light scattering, isothermal titration calorimetry and partitioning through semi-permeable membrane. It was established that poly(2-ethyl-2-oxazoline) exhibits greater ability to bind iodine compared to poly(N-vinylpyrrolidone). Despite the difference in the binding ability of these two polymers, their iodophors exhibited similar antimicrobial properties.
