Could super metallic glue replace soldering and welding?

MesoGlue, developed by Hanchen Huang, a Northeastern University professor of mechanical and industrial engineering, works by interlocking metal nanorods that are treated with a coating of gallium or indium. The two substances are kept separate until a bond is desired. The gallium-coated nanorods are applied to one metal surface, while the indium-coated rods are applied to the other surface you wish to glue. The nanorods, once applied, stand up at an angle like the teeth on a comb. When the two surfaces are pressed together, the nanorods interlock in a similar way to Velcro. The gallium and indium react with each other to form a liquid that oozes into any open space. The liquid mixture then reacts with the exposed metal cores of the nanorods, solidifies, and binds the two surfaces together.
