The phenomenon whereby atoms take a positive or negative charge by losing or gaining one or more electrons forms the basis of the known chemical or physical processes. However, atoms that have outer shell of valence electrons unfilled execute electronic transitions while heating locally depending on ...
Seeing with photons is fine if you want to look at things that are much bigger than atoms. But if you want to see things that are smaller, photons turn out to be pretty clumsy and useless. Just imagine if you were a master wood carver, renowned the world over for the finely carved ...
OpenQuantum’s platform is a fully open-source magneto-optical trap which can be used to collect, control, and manipulate ultracold rubidium atoms.The design is fully open-source, and includes all the CAD files, machining instructions, electronics schematics, PCB files, firmware, and software ...
Shohini Gose quantum physicist says in her TED talk that quantum physics describes the behaviour of atoms and fundamental particles, like electrons or photons. A quantum computer operates by controlling the behaviour of these particles, which is very different from the way our traditional computers wo...
A silicon atom will always look for ways to fill up its last shell, and to do this, it will share electrons with four nearby atoms. It's like each atom holds hands with its neighbors, except that in this case, each atom has four hands joined to four neighbors. That's what forms th...

The reason for this degradation is straightforward: including impurities like boron to create p-type silicon also causes inclusions of other atoms. One such atom is oxygen – this is more or less unavoidable and comes from the physical tools used to refine silicon. Unfortunately, oxygen ...
When the ultraviolet light strikes atom of the phosphors (shown here as white dots), it excites their electrons in just the same way that the mercury atoms were excited. This makes the phosphor atoms unstable, so they give off their excess energy as photons—which, this time, happen to be...
With enough heat and pressure, our protostar's heart ignites, starting nuclear fusion. Hydrogen gas atoms begin to fuse, creating helium and releasing an immense amount of energy. At this point, however, the outward force of this fusion isn't quite enough to counteract the inward pull of gra...
