electricity

The piezoelectric effect is the key to the operation of this artificial tree that produces energy.

New scientific milestone after 80 years of study. They manage to transform hydrogen into metal.

The electricity that circulates through conventional copper cables is made up of the movement of free electrons.

Materials with numerous applications in astronomy, electronics, biomedicine ... can be obtained from this element.

It is the state of matter that is most present on the planet and occupies the fourth place, after solid, liquid and gas.

For the first time, a team of scientists from the Georgia Institute of Technology and Columbia University (USA) has managed to demonstrate the piezoelectric properties of a material as flexible as graphene, generating electric current through mechanical deformations in molybdenum disulfide, which has resulted in the finest electrical generator ever achieved.

When the famous novel Frankenstein was published in 1818, electricity was little less than a living room rarity, although there were already scientists experimenting with it for useful purposes.

Each ray is about 5 kilometers long by only 1 centimeter wide. In that journey, he unleashes an enormous energy. So much so that if all the lightning strikes in the world were united in one day, they would be equivalent to exploding 2 million tons of dynamite.
