International Classification:

F21V 9/16
H01L 33/06

US Classification:

2504591, 2504581, 977773, 977950

Abstract:

An embodiment of the invention is a device for photo-stimulated color emission having at least one plurally doped semiconducting nanoparticle comprising at least one semiconducting material and a plurality of at least one dopant coupled with an irradiation source such that the plurally doped semiconducting nanoparticle emit electromagnetic radiation at two or more wavelengths where the intensities of the emissions depend on the intensity of the irradiation. In an embodiment of the invention, the plurally doped semiconducting nanoparticle can be a doped core/shell nanoparticle where the plurality of dopants can reside in exclusively the core, exclusively the shell, or in both the core and shell.

Abstract:

The present invention concerns size- and shape-controlled, colloidal superparticles (SPs) and methods for synthesizing the same. Ligand-functionalized nanoparticles such as nonpolar-solvent-dispersible nanoparticles, are used, and the solvophobic interactions can be controlled. Advantageously, supercrystalline SPs having a superlattice structure, such as a face-centered cubic structure, can be produced. Further, the methods of the invention can provide SPs that self-assemble and are monodisperse. The SPs can be doped with organic dyes and further assembled into more complex structures.

Abstract:

A chemical process captures and convert hydrogen sulfide (HS) gas into elemental sulfur, polysulfide, sulfur dioxide and/or sulfuric acid while regenerating sodium hydroxide capture agent for further use in an initial HS capture step. Processing may include initial sodium hydroxide scrubbing of gas streams containing HS, electrochemical regeneration of the sodium hydroxide from sodium hydrosulfide or sodium sulfide, recovery of sulfur and/or sulfur dioxide from the electrochemical processing, and production of sulfuric acid from such sulfur and/or sulfur dioxide.
