A universal passive logic element of positive and negative logic, made on just one transistor, is proposed. The logic element has at least two inputs, as well as three outputs: an OR, an XOR, and an ...
The group of rare earth elements (REEs) comprises a total of 17 elements, all of which possess similar chemical properties. In addition to the two lightest elements, scandium and yttrium, the group ...
The two most promising potential element candidates are element 119, tentatively named ununennium, and element 120, aka unbinilium. These elements are so massive that they do not fit in any of the ...
Are we made of stars? This video segment adapted from NOVA features scientists studying light emissions from exploding stars, called supernovas. Their observations and analyses can tell us the origin ...
Primordial nucleosynthesis during the early universe generated hydrogen, helium, and minor lithium-7 before the cosmos cooled, halting further fusion. Stellar interiors synthesize elements up to iron ...
