摘要:The present invention relates to methods and apparatus for activation of a low reactivity, non-polar chemical compound. In one example embodiment, the method comprises introducing the low reactivity chemical compound to a catalyst. At least one of (a) an oxidizing agent or a reducing agent and (b) a polar compound is provided to the catalyst and the chemical compound. An alternating current is applied to the catalyst to produce an activation reaction in the chemical compound. This activation reaction produces a useful product. The present invention also relates to a method for oxidizing aromatic compounds by electrocatalysis to oxidized products.

摘要:A hexagonal NaLnF 4 :Yb 3 + , Er 3 + (Ln represents the elements Y, La, Gd and/or Lu) has been found to be an efficient phospor emitting green light with infrared excitation, which can be prepared by firing a mixture of Na 2 SiF 6 and coprecipitated Ln 1 -y -z Yb y Er z F 3 . Optimum firing conditions for synthesis of NaLnF 4 :Yb 3 + , Er 3 + have been found to be such that: n A. the decomposition reaction of Na 2 SiF 6 to (2NaF + SiF 4 ) is complete, n B. liquid NaF-Ln 1 -y -z Yb y Er z F 3 and hexagonal NaLn 1 -y -z Yb y Er z F 4 are co-existent, and n C. the hexagonal-to-cubic phase transition does not occur in NaLn 1 -y -z Yb y Er z F 4 . n When pumped by a Si-doped GaAs diode, properly prepared NaY 0 .57 Yb 0 .39 Er 0 .04 F 4 emit under infrared stimulation green light 4 to 5 times as bright as commercially available LaF 3 :Y 3 + , Er 3 + .

摘要:A process is provided for synthesizing synthesis gas from carbon dioxide obtained from atmospheric air or other available carbon dioxide source and water using a sodium-conducting electrochemical cell. Synthesis gas is also produced by the coelectrolysis of carbon dioxide and steam in a solid oxide fuel cell or solid oxide electrolytic cell. The synthesis gas produced may then be further processed and eventually converted into a liquid fuel suitable for transportation or other applications.
