Polymer Classification: Crystallinity01:21

Polymer Classification: Crystallinity

3.2K
Unlike ionic or small covalent molecules, polymers do not form crystalline solids due to the diffusion limitations of their long-chain structures. However, polymers contain microscopic crystalline domains separated by amorphous domains.
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...

Structures of Solids02:22

Structures of Solids

15.7K
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...

Metallic Solids

19.4K
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....

Phase Transitions: Sublimation and Deposition

18.3K
Some solids can transition directly into the gaseous state, bypassing the liquid state, via a process known as sublimation. At room temperature and standard pressure, a piece of dry ice (solid CO2) sublimes, appearing to gradually disappear without ever forming any liquid. Snow and ice sublimate at temperatures below the melting point of water, a slow process that may be accelerated by winds and the reduced atmospheric pressures at high altitudes. When solid iodine is warmed, the solid sublimes...

Structuralism01:26

Structuralism

2.3K
Structuralism, an early psychological theory developed by Wilhelm Wundt and his student Edward Bradford Titchener, sought to dissect the human mind into its most fundamental components. Wundt's groundbreaking work in his laboratory set the stage for Titchener to define structuralism's goal as cataloging the "atoms" of the mind—sensations, images, and feelings—akin to how chemists identify elements of matter.
Titchener's approach to structuralism was unique. He...

Formation of Higher-order Actin Filaments01:11

Formation of Higher-order Actin Filaments

3.1K
The polymerization of G-actin monomers into filamentous F-actin is a multi-step process. Once the F-actins are formed, they can bundle together in different arrangements to form higher-order networks and regulate cellular functions. Common examples include the formation of lamellipodia and filopodia at the cell's leading edge by actin reorganization in a migrating cell. The microvilli on the brush border epithelial cells are also formed through the F-actin network.
The high-order actin...

Summary
This summary is machine-generated.

Amorphous materials can surprisingly exhibit topological electronic order, contrary to expectations. Structural disorder induces electronic topology, leading to robust edge states and quantized conductance in crystals.

Area of Science:

  • Condensed Matter Physics
  • Materials Science
  • Crystallography

Background:

  • Crystalline symmetry dictates electronic properties, with amorphization typically detrimental.
  • Structural disorder often weakens or destroys electron band topology in crystals.

Purpose of the Study:

  • To investigate the counterintuitive induction of electronic topological order by structural disorder in crystals.
  • To analyze the topological phase transition (TPT) from trivial to topological amorphous states.

Main Methods:

  • Theoretical analysis using effective medium theory to map a phase diagram.
  • First-principles calculations to demonstrate TPT in amorphous stanane.

Main Results:

  • Atomic structural disorder can induce electronic topological order in topologically trivial crystals.
  • A nonzero spin Bott index characterizes the nontrivial topology, enabling robust edge states and quantized conductance.
  • Disorder renormalizes the spectral gap, driving the topological phase transition near the phase boundary.

Conclusions:

  • Structural disorder can lead to electronic ordering, creating topological amorphous materials.
  • Topological phase transitions can be induced by amorphization.
  • Experimental observation of electronic ordering coupled with structural disorder is anticipated.
