Photoluminescent nanodiamond particles of dynamic synthesis have enhanced photoluminescent properties produced as a result of minimizing the nitrogen content of impurities or imperfections in the nanodiamond lattice and by location of photoluminescent structures on the outer surface of the nanodiamond particles. This inhibits suppression (i.e. inactivity) of emission and enhances the intensity of the emission. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

Photoluminescent nanodiamond material

A preparation provides light or radiation attenuation between about 190 and 800 nm has an amount of diamond nanoparticles in a medium, where the diamond nanoparticles have a size between about 1 nm and 1000 nm are modified to enhance absorption or photoluminescence. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

Light attenuating formulations

Alterations utilizing nanoparticles. Certain embodiments of the invention are methods of delivering a substance to a target using a delivery-aid which includes nanoparticles. Those nanoparticles may be nanocarbon particles. Other embodiments are methods of delivering nanoparticles to a target involving placing a mask between a source of ballistic delivery of nanoparticles and the target. Other embodiments include irradiating a target to cause localized heating of the region of the target in which the nanodiamonds or OLC particles are present. Other embodiments utilize nanoparticles to make cells competent for genetic transformation. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

Nanodiamond UV protectant formulations

Polymer nanocomposites with improved resistance to high energy ionizing radiation. Certain embodiments involve methods for providing a nanocomposite material with resistance to high energy ionizing radiation using nanodiamond, zinc oxide and mixtures of these nanoparticles with other nanoparticles dispersed within the matrix. Other embodiments relate to methods of delivering and dispersing the nanoparticles through the material or a surface layer. Other embodiments include methods of forming chemical bonds between the nanoparticles and the material.

Polymer nanocomposites with improved resistance to ionizing radiation

A field emitter device consistent with certain embodiments has a substantially planar conductor forming a gate electrode. A conductive stripe forms a cathode on the insulating layer. An insulating layer covers at least a portion of the surface between the cathode and the gate. An anode is positioned above the cathode. An emitter structure, for example of carbon nanotubes is disposed on a surface of the cathodes closest to the anode. When an electric field is generated across the insulating layer, the cathode/emitter structure has a combination of work function and aspect ratio that causes electron emission from the emitter structure toward the anode at a field strength that is lower than that which causes emissions from other regions of the cathode.
