The term used to describe the structure and properties of matter is material science. This interdisciplinary field encompasses the study of the relationship between the microstructure and macroscopic properties of materials, including metals, ceramics, polymers, and composites. Material scientists investigate how the atomic arrangement and bonding of materials influence their mechanical, thermal, and electrical properties. Research in material science is crucial for developing new materials and improving existing ones, impacting various industries including engineering, electronics, and nanotechnology.
