Abstract: A process for producing nanoparticles of a substance, including in a first chamber, forming a dispersion of a substance in a fluid and bringing the fluid into a supercritical state; passing the dispersion from the first chamber through a cooling device or into a cooling zone in a second chamber, wherein the cooling device or cooling zone configured to reduce temperature of the dispersion below a temperature at which the fluid forms solid particles such that nanoparticles of the substance are formed, wherein the second chamber comprises a surface configured to receive the solid particles of the fluid and the nanoparticles of the substance; allowing pressure to decrease and/or temperature to increase in the second chamber to transform the solid particles into a gaseous state, removing the fluid in the gaseous state and with the nanoparticles remaining on the surface; and collecting the nanoparticles from the surface.

Abstract: Apparatus, and an associated method, for facilitating formation of content streams formed of content for distribution to content consumers. A request detector detects indications of demand for content. Selection of what content to be included in a content stream is based, in part, upon the demand for the content indicated by the request detector. Once selection of the content is made, the content streams are generated by retrieving the selected content. And, the content streams, once formed, are made available for distribution to the content consumers.

Abstract: Apparatus, and an associated method, for facilitating distribution of revenue generated pursuant to distribution of content, such as recorded music files or other entertainment files, to content consumers. Identification is made by an identifier of includable distribution entities that are includable in distributions of revenue derived as a result of downloading content to content consumers. A revenue allocator allocates revenues to the includable distribution entities according to a selected formula. The selected formula is dynamically alterable, depending upon demand indications, as well as other criteria.
