Using a technique called high-resolution atomic force microscopy (AFM), researchers in China have visualized the molecular structure of a hydrogen bond. Image: AFM images of 8-hydroxyquinoline on a ...

Stress is a very real factor in the structure of our universe. Not the kind of stress that students experience when taking a ...

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 carbon ...

Astronomers have now observed the radio emission from the neutral hydrogen gas (HI) in a nearby galaxy. Hydrogen gas emits radio emission in a spectral line at a very specific frequency of 1420 MHz.

Anti-hydrogen is the antimatter equivalent of the hydrogen atom. The simplest atom in our Universe, hydrogen is usually made of a single proton and a single electron. Hydrogen is also one of the most ...
