Sheets of bismuth, gallium, indium, tin and lead can now be made just a few atoms thick by crushing them at a high ...

Bismuth exhibits iridescence due to the formation of a thin oxide layer on its surface when it cools and solidifies from its molten state. This oxide layer varies in thickness, causing light waves ...

[Robin] starts with a demonstration of just how far a little bismuth depresses the melting point of tin solder — to about 135°. That allows plenty of time to work, and freeing leads from pads ...

Javier Sanchez-Yamagishi, a physicist who studies 2D materials at the University of California, Irvine, likens the ...

A similar effect can occur in metals where the molten metal cools in such a way ... temperature using Field’s metal (a combination of bismuth, indium, and tin). The key is a process that coats ...
