A combustion engine electromagnetic energy disruptor includes shaped disruptor carried in an enclosure, and configured to disrupt, distort, and/or agitate electromagnetic energy proximate a combustion engine and fuel system. The disruptor incorporates electromagnetically responsive constituents dispersed in a substantially water-free resin hardened above about Shore D 60 into a predetermined volume and density. The resin and constituents are combined to have a mass ratio of about 50% resin and 50% powdered constituents. A permittivity of the enclosure does not exceed about 3.5, and of the resin and constituents in combination substantially exceeds about 3.5. The resin includes a urethane resin that is mixed prior to curing into a substantially homogenous dispersion with the constituents. The constituents include one or more of piezoelectric, diamagnetic, paramagnetic, ferrimagnetic, and ferromagnetic materials. Such materials include one or more of powdered quartz, black tourmaline, magnetite, iron, iron oxide, zinc oxide, copper oxide, aluminum, and graphite.

A toroidal microinductor comprises a nanocomposite magnetic core employing superparamagnetic nanoparticles covalently cross-linked in an epoxy network. The core material eliminates energy loss mechanisms in existing inductor core materials, providing a path towards realizing low form factor devices. As an example, both a 2 H output and a 500 nH input microinductors comprising superparamagnetic iron nanoparticles were modeled for a high-performance buck converter. Both modeled inductors had 50 wire turns, less than 1 cm.sup.3 form factors, less than 1 AC resistance and quality factors, Q's, of 27 at 1 MHz. In addition, the output microinductor had an average output power of 7 W and power density of 3.9 kW/in.sup.3.

A method for producing a magnetic material includes: selecting a mixture of isotopes of a chemical element having a desired magnetic characteristic; identifying an isotope in the mixture of isotopes meeting a selection criterion; removing the identified isotope from the mixture of isotopes using an isotope separation device to produce an enriched mixture of isotopes having a decreased concentration of the identified isotope; wherein the enriched mixture of isotopes is the magnetic material.

The invention is directed to hydrophilic and hydrophobic superparamagnetic nanoparticles and their use as contrast agents for NMR including agents that distinguish oil and water in NMR logging of geological formations containing oil or water. Methods of making these SPIONs are also described.

The present invention is directed to the syntheses of superparamagnetic nanoparticles and the incorporation of the nanoparticles as the magnetic component to form a strongly magnetic nanocomposite. The superparamagnetic nanoparticles possess no hysteresis and are too small to support eddy currents. The invention uses a ligand exchange procedure to produce aminated nanoparticles that are then cross-linked using epoxy chemistry. The result is a magnetic nanoparticle component that is covalently linked and well separated. By using this matrix-free approach, it is possible to substantially increase the magnetic nanoparticle fraction, while still maintaining good separation, leading to a superparamagnetic nanocomposite with strong magnetic properties and low magnetic losses.
