Ionic Bonding and Electron Transfer02:48

Ionic Bonding and Electron Transfer

Ions are atoms or molecules bearing an electrical charge. A cation (a positive ion) forms when a neutral atom loses one or more electrons from its valence shell, and an anion (a negative ion) forms when a neutral atom gains one or more electrons in its valence shell. Compounds composed of ions are called ionic compounds (or salts), and their constituent ions are held together by ionic bonds: electrostatic forces of attraction between oppositely charged cations and anions.
Molecular and Ionic Solids02:54

Molecular and Ionic Solids

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...
Ionic Crystal Structures02:42

Ionic Crystal Structures

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...
Formation of Complex Ions03:45

Formation of Complex Ions

A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...
Ionic Association01:28

Ionic Association

The ionic association is the association of oppositely charged ions in an electrolyte solution to form ion pairs. Bjerrum defined ion pairs as two oppositely charged ions whose electrostatic attraction exceeds the thermal energy of the system, typically expressed as 2kT. Electrostatic attraction depends on ionic charge, separation distance, and the dielectric constant of the medium. Thermal energy, represented by kT, reflects the tendency of ions to move independently due to molecular motion.
Theory of Strong Electrolytes01:23

Theory of Strong Electrolytes

The interionic forces of the strong electrolytes depend on the solvent's dielectric constant, which is the ability of a solvent to store electrical energy, based on its polarizability. and the solution's concentration. In high-dielectric solvents and in dilute solutions, weak electrostatic forces keep ions apart. However, in low-dielectric solvents or concentrated solutions, stronger interionic forces may cause ions to pair up as ionic doublets despite being fully ionized. The theory of strong...

Area of Science:

  • Materials Science
  • Solid-state Chemistry
  • Condensed Matter Physics

Background:

  • Solid electrolytes, such as silver iodide (AgI) and silver selenide (Ag2Se), are crucial components in advanced materials.
  • These electrolytes are incorporated into network glasses (chalcogenides, oxides) to enhance electrical conductivity for applications in batteries, sensors, and displays.

Purpose of the Study:

  • To investigate the molecular structures of composite glasses containing AgI and Ag2Se.
  • To understand the relationship between molecular structure, glass transition temperatures, and ion transport mechanisms.
  • To differentiate between homogeneously alloyed and phase-separated composite glasses.

Main Methods:

  • Analysis of composite glass structures using glass transition temperature measurements.
  • Characterization of phase separation and homogeneous network formation.
  • Quantitative analysis of bimodal glass transition temperatures based on network connectivity.

Main Results:

  • Composite glasses exhibit either intrinsic phase separation (bimodal glass transition temperatures) or a microscopically homogeneous network (single glass transition temperature).
  • Identified glass transition temperatures for AgI and Ag2Se phases as 75°C and 230°C, respectively.
  • Demonstrated that bimodal glass transition temperatures can be explained by network connectivity and fast-ion motion of Ag+ cations.

Conclusions:

  • The study provides a method to distinguish between phase-separated and homogeneously alloyed composite glasses.
  • Understanding these structures is key to optimizing ion transport in superionic conductors.
  • Findings offer insights for designing high-performance solid electrolytes for energy storage and sensing devices.
