Abstract
Methods of inducing or controlling particle motion in suspensions and colloids are described. In one aspect, a method of inducing particle motion in a suspension comprises contacting the suspension with a gas phase to establish at least one interface between the gas phase and continuous phase of the suspension. One or more gases of the gas phase are transferred across the interface to provide a solute gradient in the continuous phase, the solute gradient inducing motion of the suspended particles.
Claims21
A method of inducing or affecting particle motion in a suspension comprising:
- contacting the suspension with a gas phase to establish at least one interface between a gas phase and aqueous-based suspension continuous phase, the aqueous-based suspension continuous phase comprising one or more additives selected from the group consisting of protic species, polar aprotic species, ionic species, and mixtures thereof;
- transferring one or more gases of the gas phase across the interface to provide a solute gradient in the continuous phase, the solute gradient inducing or affecting motion of the suspended particles.
A method of inducing or affecting particle motion in a suspension comprising:
- contacting the suspension with a gas phase to establish at least one interface between a gas phase and suspension continuous phase;
- transferring one or more gases of the gas phase across the interface to provide a solute gradient in the continuous phase, the solute gradient inducing or affecting motion of the suspended particles, wherein the suspended particles comprise inorganic particles, polymeric particles, or combinations thereof.
