They transform water into a metallic material that conducts electricity They transform water into a metallic material that conducts electricity. It is a well-known fact that pure distilled water is an almost perfect insulator and does not conduct electricity. It consists of H2O molecules that are linked together through hydrogen bonds. However, any impurities, such as salts, in water allow it to conduct electricity. To create a conduction band with freely moving electrons, the water would have to be pressurized to such an extent that the orbitals of the outer electrons overlap, something that only exists inside large planets like Jupiter. Now, a team of researchers from 11 institutions around the world has used a completely different approach to create metallic water for the first time . They achieved this by forming a thin layer of gold-colored metallic water on the outside of a drop of liquid metal and documented this phase transition at the BESSY II facility in Berlin.



They transform water into a metallic material that conducts electricity The key to the breakthrough was pairing water with alkali metals, which release their external electron very easily. They transform water into a metallic material that conducts electricity. Solar - powered desalination device aims to supply water to 400,000 Kenyans The problem is that water and alkali metals are very Cell Phone Number List difficult to mix: the metals can spark, ignite, and even explode when dropped into water. But the researchers managed to avoid a potential explosion not by putting the metal in water, but by pouring some water over the alkali metal, an alloy of sodium and potassium (Na-K), which is liquid at room temperature. The experimental setup consists of a high-vacuum sample chamber containing a fine nozzle from which the liquid Na-K alloy drips. The silver drop grows for about 10 seconds until it detaches from the nozzle.



As the droplet grows, some water vapor flows into the sample chamber and forms an extremely thin skin on the surface of the droplet, just a few layers of water molecules. This almost immediately causes the electrons and metal cations to dissolve from the alkaline alloy into the water, creating conductive metallic water.

The silver droplet of sodium and potassium is covered with a golden glow, which is very impressive!, reports Dr. Robert Seidel, who supervised the experiments on BESSY II. This configuration leads to the formation of a transient golden-colored layer of metal water solution covering the metal alloy droplets. The thin layer remains visible for a few seconds, allowing researchers to demonstrate with spectroscopic analyzes on the BESSY II that it is in fact water in a metallic state. “Our study not only shows that metallic water can indeed be produced on Earth, but also characterizes the spectroscopic properties associated with its beautiful golden metallic luster,” says Seidel.
