Structures of Solids02:22

Structures of Solids

17.8K
Solids in which the atoms, ions, or molecules are arranged in a definite repeating pattern are known as crystalline solids. Metals and ionic compounds typically form ordered, crystalline solids. A crystalline solid has a precise melting temperature because each atom or molecule of the same type is held in place with the same forces or energy. Amorphous solids or non-crystalline solids (or, sometimes, glasses) which lack an ordered internal structure and are randomly arranged. Substances that...

Phase Transitions: Melting and Freezing02:39

Phase Transitions: Melting and Freezing

11.6K
Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...

Molecular and Ionic Solids

16.4K
Crystalline solids are divided into four types: molecular, ionic, metallic, and covalent network based on the type of constituent units and their interparticle interactions.
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...

Molecular Comparison of Gases, Liquids, and Solids

50.1K
Particles in a solid are tightly packed together (fixed shape) and often arranged in a regular pattern; in a liquid, they are close together with no regular arrangement (no fixed shape); in a gas, they are far apart with no regular arrangement (no fixed shape). Particles in a solid vibrate about fixed positions (cannot flow) and do not generally move in relation to one another; in a liquid, they move past each other (can flow) but remain in essentially constant contact; in a gas, they move...

States of Water01:23

States of Water

46.5K
Water exists in any one of the three classical states: solid (ice), liquid (water), and gas (steam or water vapor). The state of water depends on i) the intermolecular forces that draw molecules together and ii) the kinetic energy that leads to movements that pull them apart.
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...

This summary is machine-generated.

We introduce two new structural fields, scalar volume and vectorial geometric polarization, derived from Voronoi tessellations in fluids. These fields offer insights beyond standard correlations, revealing unique relaxation behaviors in supercooled liquids.

Area of Science:

  • Physics
  • Materials Science
  • Computational Chemistry

Background:

  • Standard 2-point density correlation functions incompletely capture fluid structure.
  • Supercooled liquids exhibit complex dynamics and structural arrest.

Purpose of the Study:

  • Introduce novel conserved fields from Voronoi tessellations.
  • Characterize static and dynamic properties of these fields in glass-forming liquids.
  • Investigate the relationship between new fields and established liquid properties.

Main Methods:

  • Voronoi tessellation analysis of fluid configurations.
  • Calculation of scalar (volume) and vectorial (geometric polarization) fields.
  • Study of static correlations and dynamical properties in the supercooled regime.

Main Results:

  • Two new conserved fields, volume and geometric polarization, are proposed.
  • Geometric polarization shows static correlation with the force field.
  • Geometric polarization exhibits a distinct plateau regime upon cooling, unlike the force field.

Conclusions:

  • The proposed fields provide structural information beyond 2-point correlations.
  • The distinct relaxation of geometric polarization is linked to the cage effect in glass-forming liquids.
  • These findings enhance understanding of structural dynamics in supercooled systems.
