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

It has been established that, with increase in the silver concentration in polymer film, there is a shift in position of the maximum in absorption spectra into the longwave region. Bands in the absorption spectra in the range 400–510 nm correspond to surface plasmon resonance (SPR) of the silver nanoparticles. It is shown that silver-containing film is an adsorbent in relation to water vapour over saturated solutions of ammonium chloride, potassium nitrate, and sodium sulphate, with maximum sorption observed in the case of Na2SO4.
