The hydrogen atom (blue) hits the graphene surface (black) and forms an ultra-fast bond with a carbon atom (red). The high energy of the impinging hydrogen atom is first absorbed by neighboring ...

Birefringent crystalline materials are essential in advanced optical technologies such as isolators and modulators due to ...

Hydrogen atoms are close together. The electron from each atom feels the attraction from the proton in the nucleus of the other atom. This attraction pulls the atoms together and the electrons are ...
