摘要:
A method is disclosed for the separation of coal from run of mine (ROM) coal containing particles of coal and refuse, which comprises conditioning the ROM coal with a coupling agent capable of selectively coating the particulate coal to the substantial exclusion of coating the refuse, which coupling agent is at least one alcohol containing from about 6 to about 22 carbon atoms. Combined with said coupling agent is a fluorescent dye in a quantity to make the coated particles of coal fluoresce upon excitation to a degree sufficient to distinguish the coated coal particles from the substantially non-coated refuse. Exciting (e.g. as with ultraviolet light) the fluorescent dye coupled to the coal particles induces fluorescence and enables separating the fluorescing, coated coal particles from substantially non-fluorescing, non-coated refuse particles.
摘要:
A method of separating a mineral component from particulate ore consisting of many components, such as oxides, silicates, carbonates, sulfides etc. is disclosed. The particulate ore is conditioned with a surface-active agent capable of selectively coating one of the components of the ore to the substantial exclusion of coating the other components. A coloring agent having an affinity towards the coating of surface active agent is combined with the surface active agent, providing the coated ore particles with a distinguishable color from the non-coated ore particles. The distinguishable color-coated ore particles are separated from the non-coated ore particles.

A method is disclosed for the separation of oil shale from run of mine (ROM) oil shale containing particles of oil shale and refuse, which comprises conditioning the ROM oil shale with a coupling agent capable of selectively coating the kerogen hydrocarbons in the particulate oil shale to the substantial exclusion of coating the non-hydrocarbonaceous refuse, which coupling agent is one or more compounds selected from the group consisting of an alcohol, at least one carboxylic acid, preferably containing from about 5 to about 28 carbon atoms and a ketone. Combined with said coupling agent is a fluorescent dye in a quantity to make the coated particles of oil shale fluoresce upon excitation to a degree sufficient to distinguish the coated oil shale particles from the substantially non-coated refuse. Exciting (e.g. as with ultraviolet light) the fluorescent dye coupled to the oil shale particles induces fluorescence and enables separating the fluorescing, coated oil shale particles from substantially non-fluorescing, non-coated refuse particles.

摘要:
Functionalized fullerenes are used in a method of combating fungal growth on surfaces and treating fungal diseases of patients. Surfaces that can be treated by the materials comprising an effective amount of functionalized fullerenes include those of fruits, vegetables, harvested grains, plants, or plant seeds. The method of combating fungal growth on a surface can be augmented but is not dependent on irradiation of the surface by light. Functional fullerenes are employed in various dosage forms such as topical, ingestible or administration.
摘要:
Functionalized fullerenes, when excited at any of a broad range of wavelengths in an oxygen free environment, undergo luminescence. The oxygen sensitive luminescence of functionalized fullerenes is used for numerous applications including oxygen detection; irradiation induced healing of polymeric materials; and phosphors for optical location and display applications. The degradation of the functionalized fullerenes allows for the detection of oxygen by diminished luminescence when the fullerenes are exposed to an irradiation source, such as a laser beam, in the presence of oxygen. The luminescence from a portion of a surface of a material with functionalized fullerenes allows for the location of the surface containing a functionalized fullerene target in the absence of oxygen or to heat the object in the area irradiated that is exposed to oxygen. The localized heating can be used to repair defects to a material containing the functionalized fullerenes. Materials containing functionalized fullerenes can be used as phosphors in display applications.
摘要:
Electromagnetic irradiation of functionalized fullerenes in an oxygen-free environment induces conversion of the functionalized fullerenes to carbon nanotubes, carbon nanohorns, carbon onions, diamonds and/or carbon schwarzites. The carbon nanotubes can be multi-wall carbon nanotubes. Advantageously, the subject invention can be used for in-situ synthesis of carbon nanostructures within a matrix to form a carbon nanostructure composite, where positioning of the carbon nanostructures is controlled by the manner of dispersion of the functionalized fullerenes in the matrix. Carbon nanotube comprising features, such as electrical connects, can be formed on a surface by irradiating a portion of a functionalized fullerene coating with a laser beam.

Fullerenes, when irradiated with electromagnetic radiation, generate acoustic waves. A photoacoustic tomography method using a material comprising fullerenes is disclosed that includes irradiating the material with a radiation beam such as a laser. The resultant photoacoustic effect produced by the material is detected by at least one detector. A photoacoustic tomography system using a material comprising fullerenes is also described.
