Superpolymers, ultraweak solids and aggregates

OCT 01, 1984
Particles up to 1000 Å in size act like atoms or molecules and come together to form flexible chains, periodic lattices and entities with fractal geometries.

In elementary science courses, we learn that matter can exist in the gaseous, liquid or solid states. In more advanced courses, we divide the solid state into regular periodic solids, possibly with defects, and amorphous solids such as glasses. Although these classifications are useful, they are incomplete and do not reflect the full variety of states of natural and synthetic materials.
