To create such miniature metal figures, experts experimented with gallium. It is a soft silvery metal used in semiconductors. Its property is the ability to turn into a liquid at a temperature slightly above room temperature.
Scientists report that the technique they developed will make it possible to develop more durable and at the same time lighter materials in the future. This will help clean up the environment or produce innovative electronic products.
In their current experiments, the experts studied nickel, copper, zinc, tin, platinum, bismuth, silver and aluminum. They dissolved the metal in gallium at high temperatures and then cooled it. This is how metal crystals were formed.
