Publication number: 20140076818Abstract: A device for crystalline-enhanced magnetic activation of water and aqueous materials includes a target material container, a crystalline material, an optional conductive metal layer, and a magnet, whereby a target material can be activated by the magnetic field, which radiates through the crystalline material and the conductive metal layer. A method for magnetic activation includes exposing a target material to a magnetic field, while heating the target material, then subsequently cooling the target material to an ambient temperature, and finally actively cooling the target material. Also disclosed is a method to replicate a natural water source, comprising analyzing a natural water source, adding minerals to pure water, heating the re-mineralized pure water, cooling the target material water, while the target material water is exposed to a crystalline-enhanced magnetic field.Type: ApplicationFiled: September 8, 2013Publication date: March 20, 2014Inventor: Douglas Benjamin Kankiewicz

Publication number: 20140076819Abstract: New multifunctional synthetic nanoparticles are adapted for water treatment, with environmentally-functional layers, optional capping layers, and synthetic antiferromagnetic cores. With high surface-to-volume ratio, these nanoparticles are very efficient in water treatment, including but not restricted to water disinfection, photo-catalytic degradation, contaminant adsorption, etc., in the context of drinking water or waste water treatment. Meanwhile, their magnetic cores are highly magnetically responsive and can be separated by 99% within 10 min using simply a permanent magnet. Moreover, once some non-degradable chemicals (like perfluorinated compounds) are absorbed to the particle surface, these chemicals can be further degraded by introducing hyperthermia or eddy current heating. These particles can be redispersed after the external magnetic field is removed, and can therefore be used in a regenerative treatment process, substantially reducing the cost while eliminating contaminated byproducts.Type: ApplicationFiled: September 19, 2013Publication date: March 20, 2014Inventors: Mingliang Zhang, Xing Xie, Shan X. Wang, Craig S. Criddle

Patent number: 8673048Abstract: Iron impurities may be removed from volumes of molten aluminum or magnesium metals or alloys by applying a static magnetic field gradient to each of the molten metal volumes, or melts. The magnetic field gradient is applied to each of the melts so that separate-phase iron impurities suspended therein will move in the direction of the applied magnetic field and become concentrated in a predetermined region of the of the melts, thereby forming an iron-rich region. The remaining iron-depleted region of each of the melts can be physically separated from the as-formed iron-rich region and cast into shaped articles of manufacture or into semi-finished articles for further processing. Such articles will have a lower iron-content than the original molten metal volumes.Type: GrantFiled: December 12, 2011Date of Patent: March 18, 2014Assignee: GM Global Technology Operations LLCInventors: Guangling Song, Jan F.

Patent number: 8673153Abstract: A method for dividing an analyte present in a solution and that is fixed on magnetic particles, and devices to be used in the method and systems for implementing the method. The method includes sedimentation of the magnetic particles together with separation into a plurality of residues. One implementation: forms at least a residue of magnetic particles in a first receptacle; and displaces the at least the residues towards a plurality of second receptacles, preferably by relative translation of a magnetic system. The second receptacle is connected to the first receptacle through a fluid channel.Type: GrantFiled: December 13, 2004Date of Patent: March 18, 2014Assignees: Commissariat a l'Energie Atomique, Biomerieux SAInventors: Raymond Campagnolo, Christian Jeandey, Frederic Ginot, Patrick Pouteau
