    摘要： A process for preparing a coated substrate in which mist particles are created from a dilute liquid, the mist particles are contacted with a pressurized carrier gas and contacted with radio frequency energy while being heated to form a vapor, and the vapor is then deposited onto a substrate. The coated substrate is then heated to a temperature of 450 to 1,400 degrees centigrade for at least ten minutes.

    摘要： A process for moving a magnetized object at a velocity in excess of 10 kilometers per second is provided. In this process, a symmetrical chamber which contains alternating portions of superconductive material and electromagnetic coils is provided. A magnetized object is disposed within the chamber and caused to levitate there because of the Meissner effect. The magnetized object is accelerated within the chamber by supplying asynchronous direct current pulses to the coils within the chamber.

    摘要： In accordance with the present invention, there is provided a composition of matter comprised of about 90% by weight of particles smaller than about 100 nanometers comprised of magnetic atoms. These nanomagnetic particles have a first magnetic moment between about 2 to about 3,000 emu per cubic centimeter, and a magnetic durability such that after about 6 months the magnetic moment does not vary by more than 5%. The nanomagnetic material, when used with implantable medical devices, upon exposure to magnetic resonance imaging (MRI) radiation, reduces the eddy currents, improves the imageability, cancels the positive susceptibility, improves the magnetic field about such devices, and may be used to modify the magnetic susceptibility of such devices. Also provided in accordance with the present invention is a preferred process for preparing such nanomagnetic material, certain preferred devices that comprise the nanomagnetic material, and a process for preparing certain flexible implantable medical devices that comprise the nanomagnetic material.

    摘要： An assembly for shielding an implanted medical device from the effects of high-frequency radiation and for emitting magnetic resonance signals during magnetic resonance imaging. The assembly includes an implanted medical device and a magnetic shield comprised of nanomagnetic material disposed between the medical device and the high-frequency radiation. In one embodiment, the magnetic resonance signals are detected by a receiver, which is thus able to locate the implanted medical device within a biological organism.
