Structures of Solids02:22

Structures of Solids

18.9K
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...

Factors Affecting Dissolution: Polymorphism, Amorphism and Pseudopolymorphism01:21

Factors Affecting Dissolution: Polymorphism, Amorphism and Pseudopolymorphism

755
Polymorphism refers to the existence of a drug substance in multiple crystalline forms, known as polymorphs. Recently, this term has been expanded to include solvates (forms containing a solvent), amorphous forms (non-crystalline forms), and desolvated solvates (forms from which the solvent has been removed).
Some polymorphic crystals possess lower aqueous solubility than their amorphous counterparts, leading to incomplete absorption. For instance, the oral suspension of Chloramphenicol, which...

pH Scale

Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

Additional Subnuclear Structures

5.4K
The eukaryotic nucleus is a double membrane-bound organelle that contains nearly all of the cell’s genetic material in the form of chromosomes. It is rightly called the “brain” of the cell as it shoulders the responsibility of responding to various physiological processes, stress, altered metabolic conditions, and other cellular signals. 
The nucleus contains many membrane-less subnuclear organelles or nuclear bodies, such as nucleoli, Cajal bodies, speckles,...

Scaling01:26

Scaling

604
In designing and analyzing filters, resonant circuits, or circuit analysis at large, working with standard element values like 1 ohm, 1 henry, or 1 farad can be convenient before scaling these values to more realistic figures. This approach is widely utilized by not employing realistic element values in numerous examples and problems; it simplifies mastering circuit analysis through convenient component values. The complexity of calculations is thereby reduced, with the understanding that...

Thermometers and Temperature Scales01:22

Thermometers and Temperature Scales

7.8K
Any physical property that depends consistently and reproducibly on temperature can be used as the basis of a thermometer. For example, volume increases with temperature for most substances. This property is the basis for the common alcohol thermometer and the original mercury thermometers. Other properties used to measure temperature include electrical resistance, color, and the emission of infrared radiation.
As many physical properties depend on temperature, the variety of thermometers is...

Summary

Amorphous ices exhibit hyperuniformity, a state with suppressed density fluctuations. Pressure-induced transitions to high-density amorphous ice disrupt this, challenging the "frozen-liquid" glass model.

Area of Science:

  • Condensed matter physics
  • Materials science
  • Physical chemistry

Background:

  • Amorphous ices, including low-density amorphous ice (LDA) and high-density amorphous ice (HDA), are critical in various scientific fields.
  • Understanding their large-scale structure and phase transitions is essential for materials science and physical chemistry.

Purpose of the Study:

  • To investigate the large-scale structure of amorphous ices and their transitions.
  • To quantify density fluctuations and assess hyperuniformity in LDA and HDA.
  • To challenge the prevailing "frozen-liquid" model of glasses.

Main Methods:

  • Simulating the isothermal compression of LDA and hexagonal ice to form HDA.
  • Quantifying large-scale density fluctuations to characterize structural properties.
  • Analyzing the degree of hyperuniformity and hyposurficiality in different ice phases.

Main Results:

  • Both LDA and HDA exhibit near hyperuniformity, characterized by suppressed large-scale density fluctuations.
  • Nonequilibrium phase transitions to HDA lead to structural heterogeneities that significantly reduce hyperuniformity.
  • The system transitions to a hyposurficial state, lacking surface-area fluctuations, during these transformations.

Conclusions:

  • The study reveals that amorphous ices possess unique large-scale structural properties, including hyperuniformity.
  • Pressure-induced transitions alter these properties, challenging the conventional understanding of glasses as simple arrested liquids.
  • Findings offer new insights into pressure-induced structural transformations in amorphous materials, with implications beyond water ice.
