Thus, there is a clearly defined relationship between the properties of concrete and the features of the structure of cement stone: increasing the number of low-basic calcium hydrosilicates as well as increasing gel content and, correspondingly, reducing capillary porosity, especially at the submicroscopic level, predetermine the increase in strength and decrease in the permeability of concrete.
By showing the alignment of molecular bonds and submicroscopic shapes, polarized light offered a way to bridge the resolution gap between light and electron microscopy, while observing living cells.

Researchers have long known that the Moon's surface darkens over time because tiny meteorites pepper the lunar dust, momentarily flash-melting iron-bearing silicate minerals and creating submicroscopic bits of metallic iron.
We would like to note that, in this article, we do not intend to analyze the theoretical basis of the "segmentation principle" or study how visual tools help enhance learning submicroscopic processes, like enzymes under action.
