Reinventing the Colander

Caption

To separate molecules usually a "colander" type of filter is used (Left side). A new type of filter, where the holes of the sieve can be activated is explored. (Right side) Thanks to an external power input, the holes of the sieve (here doors) can be opened and closed. This power input plays the role of a crazy Maxwell Demon -- similar to a bouncer.
