Abstract
A free standing liquid membrane is disclosed that can selectively separate objects based on the kinetic energy value of the objects such that either an object having a first kinetic energy value can pass through the free standing liquid membrane while retaining the membrane and/or an object having a second kinetic energy value is prevented from passing through the membrane while retaining the membrane. Advantageously, the free standing liquid membrane can remain intact for seconds to hours with multiple objects passing through the membrane.
Claims13
A method of selectively separating objects, the method comprising
- passing a first object having a first kinetic energy value through a free standing liquid membrane while retaining the membrane and/or preventing a second object having a second kinetic energy value from passing through the membrane while retaining the membrane;
- wherein the first kinetic energy value is greater than the second kinetic energy value;
- and wherein the free-standing liquid membrane comprises at least one liquid and at least one surfactant.
A free-standing liquid membrane comprising at least one liquid and at least one surfactant wherein the free standing liquid membrane can remain intact for at least 5 minutes with at least 10 perturbations.
