Molecular and Ionic Solids02:54

Molecular and Ionic Solids

20.0K
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...

Network Covalent Solids02:18

Network Covalent Solids

16.1K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Metallic Solids02:37

Metallic Solids

20.6K
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....

Structures of Solids02:22

Structures of Solids

17.7K
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...

Thermal expansion and Thermal stress: Problem Solving

2.2K
San Francisco's Golden Gate Bridge is exposed to temperatures ranging from -15 °C to 40 °C. At its coldest, the main span of the bridge is 1275 m long. Assuming that the bridge is made entirely of steel, what is the change in its length between these temperatures?
To solve the problem, first, identify the known and unknown quantities. The initial length (L) of the bridge is 1275 m, the coefficient of linear expansion (α) for steel is 12 x 10-6/°C, and the change in temperature (ΔT) is 55...

Thermal Strain01:19

Thermal Strain

2.8K
Thermal strain is a concept that arises when we consider how temperature changes affect structures. Unlike the conventional assumption that structures remain constant under load, real-world scenarios often involve temperature fluctuations that can significantly impact these structures. Consider a homogeneous rod with a uniform cross-section resting freely on a flat horizontal surface. If the rod's temperature increases, the rod elongates. This elongation is proportional to the temperature...

Area of Science:

  • Polymer physics
  • Surface science
  • Materials science

Background:

  • Interfacial slippage is crucial for polymer film behavior.
  • Understanding slippage in different polymer states (viscous, rubbery, viscoelastic) is key.

Purpose of the Study:

  • To investigate the interfacial slippage dynamics of entangled polystyrene films.
  • To analyze slippage behavior on an adsorbed polydimethylsiloxane layer on silicon.
  • To develop a unified model for slippage across various polymer states.

Main Methods:

  • Studying surface capillary dynamics of polystyrene films.
  • Utilizing polystyrene with varying molecular weights.
  • Analyzing data using a linear equation J=-M∇P with a single friction coefficient ξ.

Main Results:

  • Observed interfacial slippage in both viscoelastic liquid and rubbery solid states.
  • Demonstrated that all data aligns with a single friction coefficient (ξ).
  • Developed distinct expressions for mobility (M) in rubbery films based on dominant deformation mechanisms.

Conclusions:

  • A single friction coefficient effectively describes interfacial slippage dynamics for entangled polystyrene films.
  • The mobility of viscoelastic liquid films is a sum of viscous and rubbery state mobilities.
  • The study provides a unified framework for understanding polymer film slippage.
