Summary
The study proposes analyzing the structure function S(Q) to understand liquid and glass structures. This method helps characterize medium-range order and density correlations in materials.
Area of Science:
- Materials Science
- Condensed Matter Physics
- Physical Chemistry
Background:
- Characterizing the structure of liquids and glasses is challenging due to the absence of long-range order.
- Understanding medium-range order and density correlations is crucial for material properties.
Purpose of the Study:
- To propose a method for characterizing the structural features of liquids and glasses.
- To define an 'ideality index' based on the structure function S(Q) to quantify structural coherence.
Main Methods:
- Analysis of the height and shape of the first peak of the structure function S(Q).
- Application of the analysis to S(Q) data from metallic alloy liquids obtained via x-ray diffraction and simulation.
Main Results:
- The first peak of S(Q) provides significant information on medium-range order and density correlations.
- The proposed 'ideality index' can characterize the degree of structural ideality in liquids.
Conclusions:
- The height and shape of the first peak in S(Q) are key indicators of liquid and glass structural properties.
- The 'ideality index' offers a universal parameter for comparing structural coherence across different liquids and glasses.

Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.

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...

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...

01:17Theory of Metallic Conduction
1.7K
The conduction of free electrons inside a conductor is best described by quantum mechanics. However, a classical model makes predictions close to the results of quantum mechanics. It is called the theory of metallic conduction.
In this theory, Newton's second law of motion is used to determine the acceleration of an electron in the presence of an applied electric field. Then, its velocity is expressed via this acceleration.

17.2K
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...
