  • Patent number: 9914074
    Abstract: A polar liquid mixture containing suspended or dissolved particles or solute is exposed to air or a hydrophilic surface. An exclusion zone having a reduced concentration of particles or solute is formed in the polar liquid adjacent to the interface with air or the hydrophilic surface. One or more fractions of purified polar liquid and/or concentrated particles or solute are collected. A sensor can provide feedback to the collector.

  • Patent number: 7819259
    Abstract: Systems and methods are described for separating components of aqueous mixtures, including aqueous solutions and suspensions. In one implementation, an apparatus flows the aqueous mixture over a hydrophilic surface to form a first region of purified water and a second region of at least one concentrated non-aqueous component. The apparatus can draw off either the purified water or the concentrated non-aqueous components. In one implementation, an array of tubules performs the differential extraction. In another implementation, various hydrophilic and/or hydrophobic surfaces are disposed in multiple differential extractors and some effluents may be recycled to perform complex assaying and separation. In a further implementation, an apparatus can draw off purified water just beneath the air-water interface.

  • Patent number: 6991927
    Abstract: A method is disclosed for irradiating a biological sample with far infrared (FIR) irradiation, including providing tunable FIR irradiation, removing X rays from the irradiation, and irradiating at least one biological sample with the tunable FIR irradiation, wherein at least a component of the biological sample undergoes at least one of a conformational change or a phase change in response to the irradiating. An FIR irradiation device is disclosed, including an FIR source producing an FIR irradiation having a tunable wavelength, the source being capable of continuous-wave output, and a filter receiving the irradiation from the source.
