Abstract: A method of selectively heating targeted cells within a specimen while avoiding heating of non-targeted cells is provided. The method comprises the steps of:(a) determining at least one combination of magnetic field strength and radio wave frequency (strength-frequency combination) at which only the targeted cells will resonate when the magnetic field and the electromagnetic radiation are applied to the specimen orthogonal to one another; and(b) applying a magnetic field and a radio frequency wave to the targeted cells, the strength of the magnetic field and the frequency of the radio wave corresponding to the strength-frequency combination to the targeted cells, in order to cause nuclear magnetic resonance in the targeted cells, thereby increasing the temperature of only the targeted cells.

Abstract: Halides of tungsten and molybdenum are described for use as working fluids in power plants. Specifically, tungsten pentachloride, tungsten hexachloride, molybdenum hexafluoride and molybdenum hexachloride are used as working fluids in power plants. These working fluids can be used alone in a single cycle. However, they are preferably used in one or two loops of a binary system. The working fluids can be used in combination with other known working fluids in a binary system. Specifically useful, working fluids would include water-Hg, aluminum iodide, water, and nitrogen tetroxide. The use of the novel boiler fluids of the present invention provide numerous advantages, particularly, improved efficiency.
