A liquid purification and separation apparatus for separation of pollutants in stormwater runoff is disclosed. This apparatus utilizes gravitational separation and tortuosity, resulting from a plurality of baffles both perpendicular to and oblique to the primary water flow direction, to trap substances less-dense and more-dense than water. The apparatus features improved resistance to pollutant remobilization through treatment of water volume rather than flow rates, using vertically stacked wate...

A thermoelectric transducer comprising an emitter (1) for emitting electrons according to the action of heat or an electric field, a collector (2) disposed so as to face the emitter (1) and collect electrons emitted from the emitter (1), and an electron transport layer (3) held between the emitter (1) and the collector (2) to serve as a region for transferring the electrons emitted from the emitter (1), the electron transport layer (3) being a porous body having a mixed structure of a vapor phas...
