Researchers at Northeastern University have developed a new method for welding and soldering that does not require heat. The glue-like compound called MesoGlue bonds metals together at room temperature with minimal pressure needed to initiate a bond. “It’s like welding or soldering but without the heat,” says Hanchen Huang, professor and chair of Northeastern’s department of mechanical and industrial engineering.

The technology hinges on the reaction between the metal-coated nanorods When the metal-coated nanorods come in contact with each other, they slide together, allowing the indium and gallium to come into contact. This pairing kicks off a chemical reaction that causes the two elements to liquefy. This liquid amalgam then is hardened by the metal core of each rod, creating a single structure that holds together like glue

Oh yeah, the glue is interesting as well.
It may well find it's uses but for my hobby jacking the fact that I can unsolder things is rather important.
You mean with this glue we might have an easy way to create our own Nixie tubes, thermionic valves and such?
How cool would that be?
In a lab environment, though, it is common to have vacuum chambers and other devices semi-permanently attached to a roughing pump and molecular diffusion pump. That's more the sort of use that I was thinking of.
