Methods for producing oxygen from metal oxides bearing minerals, e. g. ilmenite, the process including producing a slurry of the minerals and hot sulfuric acid, the acid and minerals reacting to form sulfates of the metal, adding water to the slurry to dissolve the minerals into an aqueous solution, separating the first aqueous solution from unreacted minerals from the slurry, and electrolyzing the aqueous solution to produce the metal and oxygen; and in one aspect, a process for producing a slurry with ferrous sulfate therein by reacting ilmenite and hot sulfuric acid, adding water to the slurry to dissolve the ferrous sulfate into an aqueous solution, separating the aqueous solution from the slurry, and electrolyzing the aqueous solution to produce iron and oxygen. In one aspect, these process are suitable for producing oxygen in outer space, e. g. on the moon or Mars.

A method for increasing the compressive modulus of aerogels comprising: providing aerogel substrate comprising a bubble matrix in a chamber; providing monomer to the chamber, the monomer comprising vapor phase monomer which polymerizes substantially free of polymerization byproducts; depositing monomer from the vapor phase onto the surface of the aerogel substrate under deposition conditions effective to produce a vapor pressure sufficient to cause the vapor phase monomer to penetrate into the bubble matrix and deposit onto the surface of the aerogel substrate, producing a substantially uniform monomer film; and, polymerizing the substantially uniform monomer film under polymerization conditions effective to produce polymer coated aerogel comprising a substantially uniform polymer coating substantially free of polymerization byproducts. Polymer coated aerogel comprising aerogel substrate comprising a substantially uniform polymer coating, said polymer coated aerogel comprising porosity and having a compressive modulus greater than the compressive modulus of the aerogel substrate, as measured by a 100 lb. load cell at 1 mm/minute in the linear range of 20% to 40% compression.
