Creating Designer Isotopes
Roland Piquepaille writes "According to a Michigan State University (MSU) news release, 'Made-to-order isotopes hold promise on science's frontier,' nuclear physicists can now start a new career as isotope designers. These scientists can build specific rare isotopes to solve scientific problems and open doors to new technologies. The lead researcher says this approach has already given us the Positron Emission Tomography (PET) scan technology. He's now going further, saying that he wants to build objects 100,000 times smaller than the atomic nucleus. He calls this 'femtotechnology.' Also available are additional details and pictures of the tools used for this kind of research, picked from a 415-page design paper." Update: 05/11 14:30 GMT by SS: Readers have noted that the summary inaccurately portrays the scale of the 'femtotechnology.' The MSU researcher refers to "the capacity to construct objects on an even more minute scale, that of the atomic nucleus 100,000 times smaller."
I don't see how Sue Nichols is wrong.
:).
She said: "Isotopes are the different versions of an element. Their nuclei have different numbers of neutrons, and thus give them different properties".
It is fairly accurate to say that isotopes are different versions of an element.
As for your remark: "Maybe she was in a hurry to go shopping", maybe you should slow down a bit?
