A British research team recently discovered through high-pressure experiments that hydrogen has a new state of matter—a solid metal hydrogen atom, and it is called the fifth phase of hydrogen's material form, confirming previous conjectures of scientists.
Hydrogen is an element that people are familiar with, and generally exists as a gas composed of diatomic molecules. This element is widely distributed on the earth, and it can be found in water, soil, air, petroleum, plants and animals. The proportion of hydrogen in the universe is even greater. Scientists have speculated that the hydrogen atoms in the universe The quantity is more than the sum of the atoms of all other elements.
Previously, scientists have predicted that under extremely high pressure, hydrogen molecules will decompose to form a completely new material form—solid metal hydrogen atoms. However, it has not been confirmed by experiments. Recently, the experiment closest to this description is that applying a pressure of up to 230 gigapascals (GPa) to hydrogen under conditions close to room temperature results in a mixed state of hydrogen molecules and hydrogen atoms.
Philip Dowler-Simpson and his team at the University of Edinburgh in the United Kingdom pushed the experiment further with diamonds on the anvil (DAC). The diamond to top anvil is an ultra-high pressure generating device that produces a very large static pressure in a very small area. Finally, at the pressure of 325 gigapascals (GPa) and close to room temperature (27 degrees Celsius), they observed the traces of the fifth stage of the expected hydrogen form of matter. Then they found the minimum conditions for this condition by limiting the temperature and pressure. The researchers speculate that the fifth phase of hydrogen is very likely to be the precursor of metal hydrogen, which is completely composed of hydrogen atoms.

Nickel coating is a type of metal coating that is applied to a variety of substrates, including stainless steel, copper, and aluminum, to enhance their properties for specific industrial applications. This process involves the electroplating of a thin layer of nickel onto the surface of the substrate, providing it with excellent corrosion resistance, wear resistance, and surface smoothness.
Nickel coating is widely used in industries where materials require protection from corrosion, such as in the automotive, aerospace, and manufacturing industries. It is particularly effective in environments where exposure to harsh chemicals or high temperatures can cause metal parts to degrade over time. The nickel coating acts as a barrier layer, preventing the substrate from coming into contact with these harmful agents.
In addition to its protective properties, nickel coating also improves the mechanical and physical qualities of the substrate. The smoothness of the nickel surface reduces friction, which can extend the lifespan of the substrate. Nickel coating also enhances the substrate's electrical conductivity, making it an ideal choice for electronic components and circuit boards.
Nickel coating can be customized to suit specific applications. For example, the thickness of the nickel layer can be increased to increase corrosion resistance and hardness. Other variations of nickel coating include nickel-cobalt alloy and nickel-phosphorous, which offer even greater protection and superior chemical and heat resistance.
In conclusion, nickel coating is a highly effective solution for protecting substrates from corrosion, wear, and tear. Its versatility and customizability make it an attractive choice for a wide range of industries and applications. By providing superior protection and enhancing the performance of substrates, nickel coating plays an important role in ensuring the longevity and reliability of industrial systems and components.
