Ion Exchange01:17

Ion Exchange

632
Ion exchange chromatography separates charged molecules from a solution by reversibly exchanging them with mobile, or 'active', ions associated with the oppositely charged stationary phase. This method can be used to separate ions, soften and deionize water, and purify solutions. The polymers comprising the ion-exchange column are high-molecular-weight and chemically stable polymers, crosslinked to be porous and essentially insoluble. They are also functionalized with either acidic or...

Pore Transport and Ion-Pair Transport01:17

Pore Transport and Ion-Pair Transport

557
Pore transport and ion-pair formation are critical mechanisms for the absorption and distribution of drugs in the body.
Pore transport, also known as convective transport, is a process where small molecules like urea, water, and sugars rapidly cross cell membranes as though there were channels or pores in the membrane. Although direct microscopic evidence is limited  but the concept of pores or channels is widely accepted based on physiological evidence. Despite the lack of direct...

Crystal Field Theory - Tetrahedral and Square Planar Complexes

43.7K
Tetrahedral Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...

Intermolecular Forces03:13

Intermolecular Forces

59.0K
Atoms and molecules interact through bonds (or forces): intramolecular and intermolecular. The forces are electrostatic as they arise from interactions (attractive or repulsive) between charged species (permanent, partial, or temporary charges) and exist with varying strengths between ions, polar, nonpolar, and neutral molecules. The different types of intermolecular forces are ion–dipole, dipole–dipole, hydrogen bonds, and dispersion; among these, dipole–dipole, hydrogen...

Protein Diffusion in the Membrane01:24

Protein Diffusion in the Membrane

4.5K
Proteins show rotational as well as lateral diffusion across the membrane. The lateral diffusion of proteins was confirmed through the cell fusion experiment where mouse and human cells were fused, resulting in hybrid cells. When the human and mouse cells fused, the specific membrane proteins on human and mouse cells were marked with the red and green-fluorescent markers, respectively. Initially, the red and green fluorescence was located on the respective hemisphere of the cell. As time...

Dialysis01:15

Dialysis

764
Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...

Background:

  • Ion transport in solid polymer electrolytes (SPEs) is complex, involving ion solvation, ion-ion, and ion-polymer interactions, alongside free volume dynamics.

  • Review and analysis of existing literature on ion transport mechanisms in SPEs.
  • Discussion of theoretical frameworks explaining ion-polymer and ion-ion interactions.
  • Examination of experimental evidence for decoupled mobility in various SPE systems.

Main Results:

  • Identified conditions for decoupled mobility: polar environments, percolated free volume, high ion concentrations, and labile ion-electrolyte interactions.
  • Highlighted the potential of structured electrolytes to overcome limitations of homogeneous systems.
  • Emphasized the role of free volume percolation in achieving high ionic conductivity.

Conclusions:

  • Structured electrolytes present a viable strategy for achieving high ionic conductivity and selectivity, surpassing simplified fluid models.
