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 ...

When a tiny hydrogen atom is in a molecule with a much bigger ... positive charge on the large atom of another molecule. In the image to the right you can see the big red atoms (oxygen in this ...

Like ordinary water—H 2 0—each molecule of heavy water contains two hydrogen atoms and one oxygen atom. The difference, though, lies in the hydrogen atoms. In ordinary water, each hydrogen ...

Two experiment collaborations, the g2p and EG4 collaborations, combined their complementary data on the proton’s inner ...

C3N4 photocatalysts offers new insights into efficient hydrogen production, supporting the shift to renewable energy.

When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...

This image illustrates the general structure of an amino acid.The central carbon atom (C) is bonded to a hydrogen atom (H), an amino group (NH2), a carboxyl group (COOH), and a variable side chain (R ...
