    • Provided is an apparatus and method for interacting with objects of interest. A filtering apparatus can comprise a channel system, through which objects of interest are able to diffuse. The channel system can comprise a channel of suitably configured non-uniform cross-sectional area along the length of the channel. In some embodiments, the channel system can be provided by a suitably configured porous bulk material. In some embodiments, channel system can comprise an interior chamber comprising filtered objects, where the filtered objects are contained on a first side by a first filtering surface, such as a semi-permeable membrane, and on a second side by second filtering surface, where the cross-sectional areas of a representative channel of the first and second filtering surfaces are not identical. The filtered objects can also be configured to interact with an externally applied body force, such as an electric field acting on charged filtered objects. The channel system is configured to interact with objects of interest on a scale which is smaller than a value several orders of magnitude larger than the mean free path of an object of interest. Some embodiments are configured to interact with particles, such as air molecules, water molecules, or aerosols. Other plate embodiments are configured to interact with waves or wavelike particles, such as electrons, photons, phonons or acoustic waves.

    • A body force per unit mass acting on mobile charge carriers within a first electrically conducting material is configured to induce at least one region of accumulation of charge within at least a portion of the first material. The magnitude of the associated change in the voltage between two given points within the first material is a function of the relevant electrical properties of the material. A second electrically conducting material can be electrically coupled to the first material via a first electrical contact. The relevant electrical properties of the second material can be configured to be different to the relevant electrical properties of the first material. The voltage difference between the two points in the first material can be different to the voltage difference between two equivalent points in the second material. The difference in the voltage difference can be employed to increase the voltage of mobile charge carriers within a portion of an open or closed electrical circuit relative to another portion of said circuit. A voltage conversion apparatus and method can be used to convert thermal energy into electrical energy, for example.
