Colloids

18.7K
Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible to the naked eye or can be seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. On the other hand, a solution is a homogeneous mixture in which no settling occurs and in which the dissolved...

Intermolecular Forces03:13

Intermolecular Forces

63.7K
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...

Comparing Intermolecular Forces: Melting Point, Boiling Point, and Miscibility

47.6K
Intermolecular forces are attractive forces that exist between molecules. They dictate several bulk properties, such as melting points, boiling points, and solubilities (miscibilities) of substances. Molar mass, molecular shape, and polarity affect the strength of different intermolecular forces, which influence the magnitude of physical properties across a family of molecules.
Temporary attractive forces like dispersion are present in all molecules, whether they are polar or nonpolar. They...

Bioavailability Enhancement: Drug Solubility Enhancement

18
Body:Bioavailability is a critical factor in determining a drug's effectiveness. It refers to the proportion of a drug that enters the circulation when introduced into the body and is, as a result, able to have an active effect. Enhancing bioavailability is essential for drugs with poor solubility, as it can significantly impact their therapeutic efficacy. Various methods are employed to increase the solubility of drugs, thereby enhancing their bioavailability.Micronization and nanonization are...

Theories of Dissolution: The Danckwerts' Model and Interfacial Barrier Model

514
Various dissolution theories provide insight into the factors that influence the dissolution rate. Danckwerts' Model suggests that turbulence, rather than a stagnant layer, characterizes the dissolution medium at the solid-liquid interface. In this model, the agitated solvent contains macroscopic packets that move to the interface via eddy currents, facilitating the absorption and delivery of the drug to the bulk solution. The regular replenishment of solvent packets maintains the...

  • Surface Chemistry
  • Colloid Science
  • Chemical Engineering

Background:

  • Surfactant micellization and interfacial adsorption are key to enhanced oil recovery.
  • Understanding mixed surfactant systems is vital for optimizing these processes.

Purpose of the Study:

  • Investigate micellization and interfacial adsorption of anionic (DAS) and nonionic (OP-n) surfactants.
  • Determine how nonionic surfactants influence the adsorption behavior of DAS.

Main Methods:

  • Molecular dynamics simulations were employed.
  • Analyzed number density profiles, interaction energies, radial distribution functions, solvent-accessible surface area, and solvation free energy.

Main Results:

  • Nonionic surfactants (OP-n) form mixed micelles with DAS.
  • Mixed micelles significantly enhance interfacial adsorption.
  • Nonionic surfactants reduce the hydrophilicity of mixed micelles, driving adsorption.

Conclusions:

  • Mixed surfactant systems offer improved interfacial adsorption compared to single surfactants.
  • Nonionic surfactant addition is a viable strategy to enhance oil recovery through improved interfacial adsorption.
