Most … Web2 days ago · However, amorphous solids tend to crystallize and lose their advantages in in vitro performance because of their higher energy [17,19]. It has been widely reported that the use of mesoporous materials provides promising results for maintaining the physical stability of amorphous solids [10,20,21,22].
In condensed matter physics and materials science, an amorphous solid (or non-crystalline solid) is a solid that lacks the long-range order that is characteristic of a crystal. The terms "glass" and "glassy solid" are sometimes used synonymously with amorphous solid; however, these terms refer specifically to … See more The term comes from the Greek a ("without"), and morphé ("shape, form"). See more Amorphous materials will have some degree of short-range order at the atomic-length scale due to the nature of intermolecular chemical bonding. Furthermore, in very small crystals, short-range order encompasses a large fraction of the See more Amorphous thin films Amorphous phases are important constituents of thin films.
