Ultrasonic Particle Surface Functionalization.
Removal of passivating layers from the particle surface.
Furthermore, the particle surface area is activated.
Particle Surface Cleaning, e.g. of glass beads or milling media.
Ultrasonic dispersion gives a high particle surface and homogeneous distribution.
The particle surfaces were rich in hydroxyl groups, giving them high hydrophilicity.
Ultrasonic cavitation improves the material transfer at particle surfaces, too.
Cavitational erosion on particle surfaces generates unpassivated, highly reactive surfaces. .
The mass transfer is furtherincreased due to the removal of passivating layers from the particle surface.
Cavitational erosion on particle surfaces generates unpassivated, highly reactive surfaces. .
This leads to a reduction of the average particle distance and increases the particle surface area.
In order for new functional groups to get to the particle surface, this boundary layer needs to be broken up or removed.
Ultrasonication improves the mixing of the pre-cursors and increases the mass-transfer at the particle surface.
In order for new functional groups to get to the particle surface, this boundary layer needs to be broken up or removed.
This stress helps to overcome the attracting forces andcarries the functional molecules to the particle surface.
When reagents react at a catalyst particle surface, the products of the chemical reaction accumulate at the contact surface. .
This stress helps to overcome the attracting forces andcarries the functional molecules to the particle surface.
During catalytic and chemical reactions, the particle surface can be blocked by residue deposition, boundary layer formation, oxide layers and fouling.
Ultrasonication improves the mixing of the pre-cursors and increases the mass-transfer at the particle surface.
Furthermore, sono-chemical effects are well known to activate the particle surface area, which leads to advantages such as faster reactions and enhanced product quality.
When dispersed,particles are typically surrounded by a boundary layer of molecules attracted to the particle surface.
By ultrasonic cavitation and the thereby caused inter-particle collision,the residues on the particle surface are broken-off and washed away by ultrasonic streaming in the liquid.
When dispersed,particles are typically surrounded by a boundary layer of molecules attracted to the particle surface.
In particular the highshear of the liquid jets causes fissure at particle surfaces and inter-particle collisions.
This means an even and fine dispersion is required as the well-dispersed particles aresurrounded by a boundary layer of molecules attracted to the particle surface.
For almost every product, it is important that particles are separated from other particles in order toenlarge the particle surface area and to achieve an uniform distribution.
It is shown that consistency of analytic approximations(the superposition of Debye and Coulomb potentials) with the results of calculations can be significantly improved by use of a screening length scaling which depends on a dusty particle size andis associated with a significant deviation of a charge density near the particle surface from the unperturbed value.
All these contributions was cross linked due to the electric charge of colloidal particles(more precisely, the electric double layer,consisting of charges on the particle surface and compensating diffusion layer in solution).
Ultrasonic cavitation causes high-speed liquid jets,high hydraulic shear and inter-particle collisions resulting in particle surface cleaning.
Beside of the mechanical effects, the powerful sonication can create free radicals, shear molecules,and activate particles surfaces.
