How does understanding radioactive decay scientists?

Radioactive decay involves the unplanned transformation of one element into another. The only way that this can happen is by changing the number of protons in the nucleus (an element is described by its number of protons). There are a number of ways that this can happen and when it does, the atom is forever changed. There is no going back -- the process is irreversible.

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.
