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

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 concentration...
Surface Tension and Surface Energy01:16

Surface Tension and Surface Energy

When a paint brush is immersed in water, the bristles wave freely inside the water. When it is taken out, the bristles stick together. The reason behind this effect is surface tension.
Consider a beaker filled with liquid. The bulk molecules in the liquid experience equal attractive forces on all sides with the surrounding molecules. However, the surface molecules experience a net attractive force downward due to the bulk molecules. The surface of the liquid behaves like a stretched membrane,...
Surface Tension01:24

Surface Tension

Surface tension is defined as the force per unit length (γ) acting along the surface of a liquid. It arises due to strong intermolecular forces of attraction. A molecule located inside the bulk of the liquid is surrounded by other molecules and experiences equal forces in all directions. However, a molecule at the surface experiences unbalanced forces because there are more neighboring molecules below than above. This creates a net inward force that pulls surface molecules toward the interior,...
Intermolecular Forces03:13

Intermolecular Forces

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 bonds, and dispersion...

Area of Science:

  • Materials Science
  • Physical Chemistry
  • Computational Chemistry

Background:

  • Controlling water behavior at silica interfaces is crucial for technologies like solar water splitting and nanoporous membranes.
  • Understanding water-surface interactions is key to optimizing material performance.

Purpose of the Study:

  • To develop an accurate machine learning interatomic potential for simulating water confined between hydroxylated silica surfaces.
  • To investigate the influence of silanol coverage and slit width on water structure and dynamics.

Main Methods:

  • Employed machine learning interatomic potential trained via active learning.
  • Achieved ab initio accuracy for simulations.
  • Studied water confined between hydroxylated silica surfaces with varying silanol coverages and slit widths.

Main Results:

  • Partially hydroxylated surfaces (50% and 75% OH) exhibit stronger water-surface hydrogen bonding than fully hydroxylated surfaces (100% OH).
  • Translational diffusion decreases with increasing slit width and OH coverage.
  • Rotational dynamics show nonlinear responses, with specific coverages at narrow slit widths significantly altering water ordering and hindering reorientation.

Conclusions:

  • Coupled control of pore size and surface chemistry allows for nonlinear tuning of interfacial water structure and transport.
  • Provides a design strategy for optimizing porous silica for specific applications, such as enhanced stability or controlled transport.
