    摘要: A method for converting depleted uranium tetrafluoride (UF4) to triuranium octaoxide (U3O8), and producing sulfur tetrafluoride, using a two step process. The first step uses heat and a mixture of the uranium tetrafluoride and an alkaline compound, either an alkaline oxide or an alkaline hydroxide, to produce U3O8 and a water-soluble metal halide. The second step uses heat, sulfur and a halogen to produce sulfur tetrafluoride and triuranium octaoxide.

    摘要: Several crystals have been identified which can be grown using standard single crystals growth techniques and which have a high birefringence. The identified crystals include Li.sub.2 CO.sub.3, LiNaCO.sub.3, LiKCO.sub.3, LiRbCO.sub.3 and LiCsCO.sub.3. The condition of high birefringence leads to their application as optical polarizer materials. In one embodiment of the invention, the crystal has the chemical formula LiK.sub.(1-w-x-y) Na.sub.(1-w-x-z) Rb.sub.(1-w-y-z) Cs.sub.(1-x-y-z) CO.sub.3, where w+x+y+z=1. In another embodiment, the crystalline material may be selected from a an alkali metal carbonate and a double salt of alkali metal carbonates, where the polarizer has a Wollaston configuration, a Glan-Thompson configuration or a Glan-Taylor configuration. A method of making an LiNaCO.sub.3 optical polarizer is described. A similar method is shown for making an LiKCO.sub.3 optical polarizer.

    摘要: A method for converting thermal energy to chemical energy by reducing a reactive oxide substrate at a constant temperature under a first atmosphere with a lower oxygen partial pressure, and then contacting the reduced oxide at the same temperature with a second atmosphere with a higher oxygen partial pressure, during which oxygen is driven into the reduced oxide by the oxygen chemical potential difference between the two atmospheres, thereby leaving fuel behind, i.e. producing fuel. A method for preparing the reactive oxide substrate by using liquid media as a binder and pore former and heating the mixture of the reactive oxide and the liquid media, thereby forming the reactive oxide substrate.
