Scientist Professor Peter Schwerdtfeger, whose research has helped explain the physics and chemistry behind the colour of gold, has been awarded a prestigious Humboldt Research Award.
The award, also known as the Humboldt Prize, is given by the Alexander von Humboldt Foundation, in Bonn, Germany, to academics whose new theories, discoveries or insights have had a significant impact on their discipline and who expect to continue producing cutting-edge research in the future.
