[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 ...

These relativistic effects are responsible for many of bismuth's surprising properties, such as its unconventional ...

"It is noteworthy that similar structural anomalies are observed in the melt of pure bismuth, which, like antimony, belongs to the chemical group of pnictogens. We have discovered that near the ...
