Types of Coprecipitation01:10

Types of Coprecipitation

5.5K
Coprecipitation is the contamination of a precipitate by otherwise soluble species and occurs via different processes. In colloidal precipitates, coprecipitation occurs via surface adsorption. For instance, barium sulfate has a primary layer of adsorbed barium ions and a secondary layer of nitrate counterions. This results in contamination of the precipitate by barium nitrate.
Sometimes, ions in a crystal lattice can undergo isomorphous replacement by inclusions of similar charge and size. For...

Imperfections in Crystal Structure: Point, Line and Plane Defects

150
A perfect crystal, in theory, has a uniform structure with the same unit cell and lattice points throughout. However, any deviation from this periodic arrangement is known as an imperfection or defect. These defects can be categorized into three types: point, line, and plane defects.Point defects occur when there is a deviation from the ideal due to missing atoms, displaced atoms, or additional atoms. These imperfections might occur due to imperfect packing during crystallization or because of...

Washing, Drying, and Ignition of Precipitates00:52

Washing, Drying, and Ignition of Precipitates

5.8K
After filtration, the precipitate is washed to remove coprecipitated impurities and any remaining mother liquor. Colloidal precipitates, such as silver chloride, are washed with an electrolyte (such as dilute nitric acid) to prevent the peptization of the precipitate. In the case of slightly soluble precipitates, the wash solution contains a common ion to reduce solubility. Lead sulfate, which is slightly soluble in water, is washed with dilute sulfuric acid. Similarly, wash solutions may be...

Area of Science:

  • Physics
  • Materials Science
  • Fluid Dynamics

Background:

  • Controlling droplet motion on surfaces is vital for natural phenomena and technologies like heat exchangers and cleaning.
  • Surface heterogeneities (topographic and chemical) create pinning forces that can capture and direct droplet movement.

Purpose of the Study:

  • To determine the physical conditions for capturing sliding droplets on surfaces with electrically tunable wetting defects.
  • To explore the use of these tunable defects for actively guiding droplet motion.

Main Methods:

  • Mapping droplet dynamics to one-dimensional point mass motion.
  • Identifying key dimensionless parameters controlling droplet trapping: trapping strength and the ratio of viscous to inertial timescales.
  • Conducting experiments on superhydrophobic surfaces with wetting defects.

Main Results:

  • Droplet trapping is governed by two dimensionless parameters: trapping strength and the ratio of viscous to inertial timescales.
  • Electrically tunable defects effectively capture and steer sliding droplets.
  • Demonstrated the general applicability of the concept on superhydrophobic surfaces.

Conclusions:

  • Electrically tunable wetting defects offer a method for precise control of droplet motion on surfaces.
  • This control enables the development of actively switchable tracks for guiding droplets, with significant potential in microfluidics.
