Liquid metal from "Terminator" has become a reality
Usually, when it comes to liquid metal, most immediately think about mercury. And if we talk about specific products, then the image of the invulnerable liquid T-1000 Terminator Robot from the James Cameron movie most likely pops up in my head. To create such a "destruction machine" is not yet possible for people, but any happy owner of a 3D printer will soon be able to print objects from similar material.
According to the magazine Advanced Materials Technologies, scientists from Oregon under the leadership of Yeghit Mengiuc have developed a new metal alloy that can be used in any 3D printer. With its help it is possible to create, for example, conductors flexible at room temperature. Oregon creators were able to solve the problem of low viscosity and high surface tension due to Galinstan, an alloy of gallium, indium and tin. Such material is melted already at 30 degrees Celsius, and the low viscosity was overcome by adding nickel particles, the diameter of which varies from 800 nanometers, to 7 micrometers.
Produce new material at such Technology: First, the alloy is poured into a vessel with particles of nickel, then placed inside the ultrasonic emitter for uniform oxidation, which ultimately increases the viscosity. The result of these manipulations is a paste-like metal. One of the practical applications of the material is the creation of expandable microcircuits in which a liquid alloy is clamped between elastic polymers.
