摘要： 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.

摘要： Disclosed is a separation device and a method for separating charged particles from a liquid stream. The separation is effected by establishing an ion concentration gradient across the direction of the liquid stream by the introduction of a gas which when contacted with the liquid, in a reversible reaction, forms a soluble ionic species. A concentration gradient is maintained across the direction of the liquid stream which in turn induces separation of charged particles within the liquid stream due to the effect of diffusiophoresis. The device operates using little or no power, and dispenses with the need for filtration media or separation membranes. The device and method is adaptable to any of a number of separation processes, including biological separation processes, water purification and industrial processes.
