Model predictions of the distribution and dynamical transport of hydrogen atoms in the terrestrial atmosphere have long-standing discrepancies with ultraviolet remote sensing measurements, indicating ...

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 ...

A model of a nanocluster catalyst featuring ruthenium atoms as green and white (with the white atoms highlighting the active centre) arranged as a flattened pyramid on a carbon support (represented by ...

Everything we can see and touch, and quite a lot that we can’t as well, is made of tiny particles called atoms. Some substances, like particles of this iron, contain only one kind of atom. Iron is an ...

An infinite chain of hydrogen atoms is just about the simplest bulk material imaginable -- a never-ending single-file line of protons surrounded by electrons. Yet a new computational study combining ...

A new map reveals the most detailed picture of hydrogen atoms in the Milky Way ever made. Benjamin Winkel and the HI4PI collaboration When it comes to the atoms and elements of the universe, hydrogen ...
