Scientists capture first video of atomic chemical bond formation and breakage

According tomedia reports, atoms are known for forming chemical bonds and splitting chemical bonds, a process that is vital to everything in the universe. But because it occurs in a very small area, it is difficult to study and document it. Now, for the first time, researchers from the University of Nottingham and Ulm University have captured the formation of atoms and the rupture of chemical bonds by video.

The team is known to have used a transmissible electron microscope (TEM) to image a pair of molyn atoms, which “walk” hand in hand on carbon nanotubes. Through the four-bond, the two atoms form a Re2 molecule.

Kecheng Cao, one of the study’s authors, said: “The way the two atoms move in pairs is very clear, which clearly shows the connection between them. Importantly, as Re2 moves down the nanotube, the length of the key changes, indicating that the strength of the key depends on the environment around the atom. “

The researchers then saw the atoms separate, stretch into an elliptical shape, and break through constant stretching. After a while they combined again into a Re2 molecule.

“As far as we know, this is the first time that the evolution, fracture, and formation of chemical bonds have been recorded at an atomic scale,” said Andrei Khlobystov, one of the study’s authors. It is also moving towards real-time understanding of individual molecular dynamics. “

Since the chemical bonds between atoms are only 0.1 to 0.3 nanometers long, which is 500,000 times smaller than the width of human hair, imaging becomes very difficult. With many unsolved mysteries still on the atomic scale, this new technology may help provide some answers.
