Billionth-of-a-meter-thick gold layers created in ten minutes

We’ve reported on some rather questionable products of gold plating technology before, including a gilded iPhone, Wii gaming system and barbecue. There are legitimate reasons to coat things in gold, however, such as in the production of nanoelectronics and semiconductors. The coatings used in these applications are infinitely thinner than what you would typically use on an iPhone, so it is of the utmost importance that they be as smooth and uniform as possible. Recently, researchers at Troy, New York’s Rensselaer Polytechnic Institute announced that they have devised a quick and simple method of producing just such coatings.
