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 technology has been developed for the production of silver films on cotton fabrics, which provides for the preliminary application film of monochloride of copper to the surface of the fabric. Physicochemical and photochemical processes are considered, leading to the formation chloride of monovalent copper, providing sufficient adhesion to the substrate. The subsequent treatment with nitrate of silver, when the substitution reaction proceeds, leads to the formation chloride of silver, which under the influence of sunlight is restored to elemental silver. It is shown that in this case also the oxidation of monovalent copper occurs to form soluble salts, easily removable by rinsing. Since the proposed technology does not require special equipment, and the chemical reagents used are not deficient, It can be used to apply bactericidal films of silver on various household products and medical use in conventional laundries or home conditions.
