Structures of Solids

20.8K
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...

Ionic Crystal Structures

20.0K
Ionic crystals consist of two or more different kinds of ions that usually have different sizes. The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size.
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

Determination of Crystal Structures

44
In the late 1800s, the revelation that light extended beyond visible wavelengths led to the discovery of X-rays by Wilhelm Roentgen. Recognized as high-energy electromagnetic radiation with short wavelengths, X-rays prompted exploration into their interaction with crystals. Max von Laue proposed in 1912 that the periodic arrangement of atoms, ions, or molecules in crystals would cause them to diffract X-rays, a hypothesis confirmed through experiments with copper sulfate and zinc sulfide...

Structure of Benzene: Molecular Orbital Model

13.5K
According to the molecular orbital (MO) model, benzene has a planar structure with a regular hexagon of six sp2 hybridized carbons. As shown in Figure 1, each carbon is bonded to three other atoms with C–C–C and H–C–C bond angles of 120°. The C–H bond length is 109 pm, and the C–C bond length is 139 pm which is midway between the single bond length of sp3 hybridized carbons (154 pm) and sp2 hybridized carbons (133 pm).

Unit Cells

A crystal's internal structure is an orderly array of atoms, ions, or molecules, and the details of this array significantly influence the solid's properties. In a crystal, periodically repeating 'structural motifs' - which could be atoms, molecules, or groups thereof - create a 'space lattice.' This is essentially a three-dimensional, infinite array of points, each surrounded by its neighbors in an identical way, forming the basic structure of the crystal.A 'unit cell' is a theoretical...

Area of Science:

  • Geotechnical Engineering
  • Clay Science
  • Material Science

Background:

  • Clay structure significantly impacts macro-mechanical behavior, necessitating quantitative characterization.
  • Existing methods lack explicit parameters to define clay structure's influence on mechanical properties.

Purpose of the Study:

  • To develop and validate quantitative parameters for characterizing clay structure.
  • To establish a model for assessing the impact of clay structure on mechanical behavior.

Main Methods:

  • A quantification model based on system theory and energy conservation was established.
  • Three parameters were proposed: deformation structure potential, strength structure potential, and comprehensive structure potential.
  • Experimental tests were conducted to validate the proposed parameters.

Main Results:

  • The proposed quantitative parameters accurately reflect clay structure's influence on deformation and strength.
  • The parameters effectively indicate the relative magnitude of structural influence on mechanical behaviors.

Conclusions:

  • The developed quantitative parameters possess clear mechanical meanings.
  • These parameters serve as effective tools for characterizing the structural influences of clay on its mechanical behavior.
