20120235074SOLVENT-BASED INKS COMPRISING COATED MAGNETIC NANOPARTICLES - Solvent-based ink compositions which can be used for ink jet printing in a variety of applications. In particular, the present embodiments are directed to magnetic inks having desirable ink properties. The ink of the present embodiments comprise magnetic nanoparticles that are coated with various materials to prevent the exposure of the nanoparticles to oxygen, and provides robust prints.09-20-2012
20100012881METHOD FOR MANUFACTURING MAGNETIC SHEET AND MAGNETIC SHEET - In manufacturing a magnetic sheet, the magnetic sheet is formed by applying on a prescribed substrate a magnetic paint made from a mixture of at least flat soft magnetic powder and polymeric binder dissolved in a solvent and drying the magnetic paint. Subsequently, the magnetic paint is further coated on the magnetic sheet formed by drying the magnetic paint and is dried. Thus, an extremely high quality magnetic sheet is made with high productivity.01-21-2010

20120037840USE OF MAGNETIC NANOPARTICLES TO REMOVE ENVIRONMENTAL CONTAMINANTS - Methods and compositions for removing a contaminant from its environment. The method includes forming a magnetic composition comprising the contaminant and an amphiphilic substance, and applying a magnetic field to the magnetic composition so as to separate the magnetic composition from the environment. One composition includes a micelle array confined in a magnetic mesoporous framework. Another composition is formed by adhering an amphiphilic material comprising functional surface groups to a contaminant, then interacting a magnetic material with the functional surface groups of the amphiphilic material. In various versions, the contaminant can be a hydrophobic organic compound, or a fullerene-related nanoparticle. The methods can also be used to purify hydrophobic organic compounds or fullerene-related nanoparticles.02-16-2012
