However, if the size of discontinuities are comparable with the size of the rock, continuum based models may lose their accuracy.
The n columns of H0 are designed as an n-dimensional subspace of a full (2n -dimensional space comparable with the size of the row space.
Furthermore, Knudsen diffusion increases because the molecular mean free path becomes comparable with the size of pore throat; in other words, the molecule/wall collisions will dominate particle/particle collisions.
When 200 nm PS nanospheres are used, the RIE process is not necessary to modify the PS nanospheres, for the resulting lateral size of the pits is about 100 nm, which is comparable with the size of QDs.
These tests and observations reveal that void growth and coalescence occurred only within a narrow localized band, whose size is comparable with the size of the graphite nodules; no statistically significant changes in the porosity were observed outside this zone.
The sizes of NPs (from 1 to 100 nm) are comparable with the size of protein globules (2 10 nm), diameter of DNA helix (2 nm), and thickness of cell membranes (10 nm), which allows them to easily enter cells and cell organelles.
