A unit cell of polyethylene showing the long, parallel macromolecules that pass through many such unit cells. The cell has an orthorhombic structure. The molecular sections shown may be different ...

The atoms of a solid are strongly attracted to each other. Solids keep their shape because of these strong attractions. The atoms vibrate but do not move past each other.

This Review highlights the synthesis principles and strategies towards controllable and predictive fabrication of high-entropy materials with complex chemical compositions, engineered ...

In this article, we explore how the molecular structure, chemical properties and ... upon freezing Ordering molecules in crystalline solid results in more void space than in the liquid phase ...
