«Exposing this multilayer system to a surprisingly small temperature difference in the direction of the layering causes stresses at the liquid - gas interface because of a temperature - dependent surface tension,» said Nejati. (sciencedaily.com)
The variability is also relatively high around the CN violet system, whose strength is very sensitive to even small temperature differences because of the high value of the dissociation potential. (aanda.org)
Which makes sense for very small temperature difference. (judithcurry.com)
