if by Kalapas, you are referring to sub-atomic particles, then i have not come across these in my readings of the Nikayas

generally, the Nikayas refer to phenomena that fall within the range of consciousness perception

for example:

(THE ELEMENTS)

When he knows and sees these eighteen elements, a monk can be called skilled in the elements.
