Crystallization is the process by which solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. Attributes of the resulting crystal depend largely on factors such as temperature, air pressure, and in the case of liquid crystals, time of fluid Web2 days ago · Various terpolymers consisting of ethylene, 1-hexene and styrenic monomer were synthesized using a metallocene catalyst and cocatalyst system.
