[Stosh]

Very lame summary in the original article.

What’s actually happening is a conversion to a form of copper that provides some catalytic properties similar to those of gold. They start off with copper and they finish with copper and at no point do they actually have gold.

Now if they want to refer to their finished material as “gold-like” in some chemical properties, especially as regards some specific catalytic properties, that’s maybe reasonable, but whoever slapped together the original article probably learned to write about science from Al Gore.

That's what I wanted to see. I don't remember enough chemistry to be able to judge.
The ignorant author of the article thinks we don't see the apostrophes around 'gold'. We ain't stoopid! Gold is not 'gold'.
Some authors will do anything and say anything to get an article in print.
