Phase systems consisting of polymers or polymers with saltwater can be used to separate cells, membranes, viruses, proteins and other biomolecules. Aqueous two-phase systems, also known as ATPS, use ...

A new phase shifter does not need clean-room facilities for fabrication, so is inexpensive to manufacture. The liquid-metal enabled phase shifting elements have a 'passive' nature, unlike the 'active' ...

When discussing electronic circuits, I often lock onto the circuit's magnitude characteristics. For example, we refer to filters as high pass, low pass, or band pass, which is a shorthand way to ...
