A method of: introducing hydrogen and a feed gas containing at least 50 vol % carbon dioxide into a reactor containing a Fischer-Tropsch catalyst; and heating the hydrogen and carbon dioxide to a temperature of at least about 190&#xb0; C. to produce hydrocarbons in the reactor. An apparatus having: a reaction vessel for containing a Fischer-Tropsch catalyst, capable of heating gases to at least about 190&#xb0; C.; a hydrogen delivery system feeding into the reaction vessel; a carbon dioxide delivery system for delivering a feed gas containing at least 50 vol % carbon dioxide feeding into the reaction vessel; and a trap for collecting hydrocarbons generated in the reaction vessel.

A resist composition with enhanced X-ray and electron sensitivity includes a plurality of chemically inert nanoparticles dispersed throughout a base resist material. The nanoparticles have a higher atomic number than the base resist material and each of the nanoparticles is formed by a nanoparticle core, e.g., of a noble metal, coated with an organic capping layer or shell. The latter renders the core dispersible and chemically compatible with the resist material surrounding the nanoparticle. A method of making a resist composition with enhanced X-ray and electron sensitivity is to provide a resist material and disperse chemically inert nanoparticles throughout the resist. The nanoparticles have a higher atomic number than the resist and a have core/shell structure. A resist composition with enhanced X-ray and electron sensitivity can be made by having a nanoparticle core, with a higher atomic number than the resist, that is coated with an organic capping layer. The nanoparticle with the core/shell structure is then dispersed throughout the resist material.

Corrosion protection in hollow metal structures is attained by placing an injected, foam-in-place, closed cell plastic polymer foam into an interior of a hollow metal structure, thereby preventing the ingress of foreign matter, such as dirt or water.
