Quantum calculations amount to sophisticated estimates. But in 1931, Hans Bethe intuited precisely how a chain of particles ...

In simple terms, that assertion is correct, but for those with an expertise in the field, the longer answer to who did it ...

Antimatter is a fascinating kind of matter made up of antiparticles, which have a mass equivalent to that of their normal ...

From helping catalyze interstellar reactions and fueling the birth of stars to its presence in neighborhood gas giants like ...

A study on gas adsorption in platinum-gold structures shows hydrogen's rapid, reversible binding and carbon monoxide's ...

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 ...

Researchers from Tokyo Metropolitan University have elucidated how hydrogen and carbon monoxide is adsorbed into solids ...

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 ...

Sucrose has many O–H bonds which are polar. These polar areas are shown with a + near the hydrogen atom and a − near the oxygen atom. The second space-filling model shows two sucrose molecules held ...

The typical size of atoms and small molecules is around 1 × 10-10 m (0.1 nm). For example: diameter of a hydrogen atom, H 1.0 × 10-10 m width of a hydrogen molecule, H 2 2.9 × 10-10 m ...
