Scientists discovered a new substance that upset the rules of physics – Cyprus Newspaper

American researchers discovered an extraordinary substance that shrinks when heated and expanded when compressed. With these features, the new material, which challenges the rules of physics, can ensure that the electric vehicle (home) batteries are performed on the first day.

Scientists from the University of Chicago Molecular Engineering and San Diego California University discovered a new class of substances that contradict the basic laws of thermodynamics.

These newly discovered metastabil substances are shrinking in volume when heated, and expanding under high pressure.

Leading the research team. Dr. Shirley Meng, « We think we can adjust the properties of these materials through Redox chemistry. This can open the door to very exciting applications, » he said. The results of the study were published in Nature magazine.

Features that challenge the rules of physics

According to the thermodynamic rules, when a substance is heated, the volume is reduced when compressed. However, researchers have developed metastabil materials that act in contrast to these rules.

Prof. Meng, « when you heat the material, the volume shrinks. This is quite unusual, » he said.

This behavior of matter is a revolutionary not only in terms of basic sciences, but also in terms of practical technologies.

It offers great opportunities especially in areas such as renewal of electric vehicle batteries, structural battery systems and heat -resistant material production.

Structural battery and zero thermal expansion may be possible

Dr. Minghao Zhang said that these new class substances can be adjusted to show zero thermal expansion. This can be groundbreaking in the construction sector.

“The heat -related volume changes of different building materials used in each building can cause serious problems. However, such problems can be prevented thanks to these materials,” he said.

In addition to heat, its behavior under pressure is surprising: the substance continues to expand even under intense pressure at the Gigapascal level.

Dr. Zhang explained this feature with the words, « If you compress a substance from all directions, you naturally expect the volume to shrink. But this substance is doing the opposite, » he said.

Aging batteries can return to the first day

Researchers also examined the reactions of these substances to electro-chemical energy. When electrical voltage is applied to these metastic substances, they can return to their original stable state. This means that the capacity of used home batteries can be increased again.

Dr. “With a voltage application, the battery can return to the first day with a voltage application.

The transition from scientific discovery to industry is aimed

Another contribution of the research is that it gives a new dimension to the understanding in the basic sciences. Prof. Meng, « This is not only technological, but also scientifically creates a paradigm change, » he said.

Researchers aim to make it applicable in many areas from energy storage systems to space technologies by examining the chemical behavior of the new substance in more detail.
