Despite its promising characteristics in condensed matter physics, the triply-degenerate semimetal PtBi2 has been largely unexplored in practical applications, particularly in semiconductor technology. The main difficulties include a lack of empirical data on the integration of PtBi2 with existing semiconductor components and the need for innovative approaches to leverage its unique properties, such as high…

Here's visible proof for the first time ever.

Got a fastener that isn't cooperating? A wrench set provides the versatility—and torque—needed to make it.

The short answer: pretty tough!
