Morphology

Definition

Morphology refers to the study of the form, structure, and arrangement of materials, particularly at the microscopic level. This concept is crucial in understanding how the physical characteristics of materials, especially nanomaterials, affect their properties and behaviors. Morphological analysis helps in revealing how variations in size, shape, and surface texture can influence the performance of materials in applications ranging from electronics to drug delivery.
