Water-resistant coating guards limestone from pollution
Buildings and statues constructed of limestone can be
protected from pollution by applying a thin, single layer of a water-resistant
coating.
That’s the word from a University of Iowa researcher and her
colleagues from Cardiff University in a paper published in the journal
Scientific Reports, from the publishers of Nature. In the study, the
researchers report a new way to minimize chemical reactions that cause
buildings to deteriorate, according to Vicki Grassian, F. Wendell Miller professor
in the UI departments of chemistry and chemical and biochemical engineering.
