Web1 day ago · 1. In a recent study published in Science Advances, a team of researchers have created a new method of making photonic time crystals, which is a type of artificial material capable of amplifying the light that is shined on them. This study holds the potential to improve both lasers and wireless communication. Time crystals were first discovered ... WebIsomorphism (crystallography) In chemistry isomorphism has meanings both at the level of crystallography and at a molecular level. In crystallography, compounds are isomorphous if their symmetry is the same and their unit cell parameters are similar [1] Molecules are isomorphous if they have similar shapes.
