'Opposite charges attract; “Charge repulsion” is a well-established fundamental principle of physics that you may have heard in school. But your teacher was probably wrong.
A new Oxford University study published in the journal Nature nanotechnology It has been found that similarly charged particles can sometimes attract each other rather than repel each other.
Researchers based at the University of Oxford's Department of Chemistry found that similar charged particles immersed in solutions were able to attract each other from long distances.
This depends on the solvent used and the sign of the charge mentioned in the study.
“I am really very proud of my graduate students, as well as the undergraduate students, who have all worked together to move the needle on this fundamental discovery,” said Madhavi Krishnan, a professor at the University of Oxford, who led the study.
