Summary
Particle properties, specifically the three-phase water contact angle, are crucial for forming stable gas marbles. An optimal intermediate contact angle is essential for successful gas marble formation and stability in edible materials.
Area of Science:
- Colloid and Surface Science
- Food Science and Technology
Background:
- Three-phase water contact angle is vital for stabilizing particle-stabilized foams and emulsions.
- Gas marbles, particle-stabilized bubbles in a gas phase, are hypothesized to be similarly influenced by this parameter.
Purpose of the Study:
- To investigate the dependence of gas marble formation on the three-phase water contact angle.
- To determine the optimal contact angle range for gas marble stabilization using various edible particles.
Main Methods:
- Examined gas marble formation with diverse edible particles (varying size, shape, composition).
- Measured the three-phase water contact angle for each particle type.
- Assessed the structure and stability of the formed gas marbles.
Main Results:
- Gas marble formation critically depends on the three-phase water contact angle.
- Hydrophobic (high angle) and highly hydrophilic (low angle) particles failed to form gas marbles.
- Moderately hydrophilic particles (intermediate angle) successfully formed stable gas marbles.
Conclusions:
- An optimal range of three-phase water contact angle is essential for gas marble formation, irrespective of particle size and shape.
- This study highlights the critical role of contact angle in gas marble stabilization.
- The resulting gas marbles exhibit remarkable stability, suggesting potential applications in edible materials.

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...

01:23Factors Affecting Dissolution: Particle Size and Effective Surface Area
1.5K
Dissolution kinetics, an essential aspect of oral drug delivery, is significantly influenced by the drug's particle size. According to the Noyes-Whitney dissolution model, the dissolution rate correlates directly with the drug's surface area. The larger the surface area, the higher the drug's solubility in water, leading to a faster drug dissolution rate. Reducing particle size increases the effective surface area, enhancing the dissolution process. Micronization and nanosizing are...

01:20Porosity and Absorption of Aggregate

Aggregates contain pores of varying sizes; while some are completely enclosed within the particles, others open onto the surface, allowing water to penetrate. The porosity of aggregates is a major factor contributing to the overall porosity of concrete, given that aggregates constitute about three-quarters of concrete's volume.
When all pores in an aggregate are filled with water, the aggregate is considered saturated and surface-dry. If left in dry air, water will evaporate until the...

In precipitation gravimetry, the precipitating agent should react specifically or selectively with the analyte. While a specific reagent reacts with the analyte alone, a selective reagent can react with a limited number of chemical species.
The obtained precipitate should be either a pure substance of known composition or easily converted to one by a simple process, such as ignition or drying. In addition, the precipitate should be insoluble and easily filterable. In general, filterability...
