Researchers at Iowa State University, has created a novel liquid metal particles. It can remain liquid at room temperature, also can make material between integration. The new solid-liquid mixture can be no heat welding, as well as electronic circuit repair aspects play a practical role. But this is a metal found some by accident, because the researchers wanted to find a way to prevent liquid metals at below the normal freezing point temperature back to solid.
This is called "supercooled" (undercooling) technique, often used to analyze the internal structure of the metal, is also an alternative to metal processing, but the biggest obstacle is made difficult to a stable supply of "cold" metal.
The team at Iowa State University, thought through and evenly thin coating to keep small drops of molten metal to form a balanced contains super-cooled liquid metal particles.
In order to create these particles, the researchers used a high-speed rotary tool, to be cut up into tiny droplets of liquid metal, and suspended in the acetic acid/diethylene glycol in the mixture. Victorias Secret iPhone 6 Case
This new type of liquid metal particles can be at room temperature no heat welding and repair of electronic circuits play an important role in such areas.
When exposed to the air, can oxidize and produce metal foam on the surface of the material. After the oxidation process, the team will be polished smooth.
Liquid metal particle diameter of only 10 microns (red blood cells), the team will observe the bubbles and repair microscopic defects and micro jointing and splicing "macro" section.
It says in the paper: "experiment proves new material at room temperature under non-destructive surface welding process without sophisticated equipment, complex materials, or high temperature metal joining process".
Thuo has applied for a patent and established startups, they are currently testing and improving the new liquid metal electrical and mechanical reliability. More papers have been published in a recent issue of the scientific report (Scientific Reports) journal.
