Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing magnetic nanoparticles sufficiently dispersed in a polymer matrix. SOLUTION: Nanoparticles are non-ferromagnetic or weakly ferromagnetic. A dispersion liquid is annealed at the temperature T FM in which non-ferromagnetic nanoparticles are transformed into ferromagnetic nanoparticles and the ferromagnetism in weakly ferromagnetic nanoparticles is increased. A magnetic field is applied to the dispersion liquid, and the nanoparticles are aligned while the dispersion liquid is heated to the temperature T A . COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a composite membrane with a performance enhancing layer, in which resistance to fouling is greatly enhanced in comparison with that of an non-coated membrane. SOLUTION: The composite membrane includes a filtration membrane with a surface and a layer on the surface of the filtration membrane. The layer includes a polymer including a poly(ethylene glycol) moiety cross-linked with ammonium salt or a precursor of the ammonium salt. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
CO-DELIVERY OF CHOLESTEROL LOWERING DRUGS AND NUTRACEUTICALS Star polymer occlusion complexes were prepared comprising i) an amphiphilic unimolecular star polymer having a crosslinked core covalently linked to 6 or more independent amphiphilic polymer arms, ii) a nutraceutical (such as coenzyme Q10), and iii) a cholesterol-lowering drug (such as simvastatin). An initial occlusion complex formed with the nutraceutical and the star polymer exhibited improved binding properties for the cholesterol-lowering drug, resulting in improved loading efficiencies for the cholesterol-lowering drug. The star polymer occlusion complexes have utility in the medical treatment of high blood cholesterol.
