One hypothesis is that the atomic structure of bismuth constrains electron movement in a way that mimics the behavior of topological materials, recently discovered exotic substances whose surfaces ...

Ram Mohan looks at how bismuth — a remarkably harmless element among the toxic heavy metals in the periodic table — has sparked interest in areas varying from medicinal to industrial chemistry.

Admittedly, we have a pretty low bar for that kind of stuff, but eye candy aside, [Robin Debreuil]’s quick outline of his technique for desoldering with the help of bismuth is worth watching.

A BISMUTH are, operating in a hydrogen atmosphere at reduced pressure (10–20 mm.), emits the line λ4722 of bismuth (Bi) with great brilliance. A faint band spectrum was found to occupy the ...
