The invention provides a slow-release material comprising particles, wherein the particles comprise a core comprising an active component and a multilayer shell, wherein the multi-layer shell comprises a molecular layer deposition (MLD) multi-layer, wherein the active component comprises one or more of a pharmaceutical compound and a nutraceutical compound, for use in the treatment of a disease.

A continuous tubular reactor includes a rotary reaction tube having a reactant inlet and a product outlet, and including a ceramic; a heating device disposed outside the rotary reaction tube; and an angle adjuster adjusting an angle of a rotation axis of the rotary reaction tube. The angle of the rotation axis is 75° or less with respect to a horizontal surface.

The present invention relates to photocatalytic materials for use in the conversion of CO.sub.2 to non-CO.sub.2 carbon containing products. The photocatalytic materials comprise a metal nanofiber and a carbon-based nanostructure bound to the surface of the metal nanofiber. Methods for preparing such materials are described, as well as their use in the conversion of CO.sub.2 to non-CO.sub.2 carbon containing products. For example, the photocatalytic materials of the invention may be used to convert CO.sub.2 to methanol and/or ethanol with high conversion rates.

Systems and methods of pyrolyzing gaseous hydrocarbons include a reaction chamber and a plenum in fluid communication therewith. A light source directs electromagnetic radiation through a window into the reaction chamber. A first recirculation conduit connected between an offtake and an intake of the reaction chamber recirculates to the intake of the reaction chamber a portion of an aerosol product from the offtake of the reaction chamber. A filter operatively associated with the offtake of the reaction chamber receives un-recirculated amounts of the aerosol product and produces a retentate that includes particulate matter removed from the aerosol product. First and second gas separators operatively associated with the filter separate hydrogen and unreacted hydrocarbons from a filtrate of the filter. A second recirculation conduit connected between the second gas separator and the intake of the plenum recirculates unreacted hydrocarbons from the filtrate to the plenum.
