Abstract: Combustion flue gas containing NOX and SOX is treated to remove NOX in a multistep system in which NOX is reduced in the flue gas stream via selective catalytic reduction or selective non-catalytic reduction with ammonia or an ammonia-forming compound, followed treatment with hydrogen peroxide to remove residual ammonia and, optionally, treatment with an alkali reagent to reduce residual NOX in the flue gas stream. The NOX-depleted flue gas stream may also be subjected to a desulfurization treatment for removal of SOX.
Abstract: A method is disclosed for directly preparing an alkaline earth metal borohydride, i.e. Mg(BH4)2, from the alkaline earth metal boride MgB2 by hydrogenating the MgB2 at an elevated temperature and pressure. The boride may also be doped with small amounts of a metal chloride catalyst such as TiCl3 and/or NiCl2. The process provides for charging MgB2 with high pressure hydrogen above at least 70 MPa while simultaneously heating the material to about 350° C. to about 400° C. The method is relatively simple and inexpensive and provides a reversible hydride compound having a hydrogen capacity of at least 11 wt %.

Abstract: Disclosed herein is a core-shell spinel cathode active material for lithium secondary batteries. The core portion of the active material is made of a spinel manganese-containing material substituted with fluorine or sulfur, having 4V-grade potential and showing low-cost and high-output characteristics, and the shell portion, which comes into contact with an electrolyte, is made of a spinel transition metal-containing material, having excellent thermal stability and cycle life characteristics and showing low reactivity with the electrolyte. Thus, the cathode active material shows significantly improved cycle life characteristics and excellent thermal stability.
Abstract: Compositions including an amido-group-containing vapor deposition precursor and a stabilizing additive are provided. Such compositions have improved thermal stability and increased volatility as compared to the amido-group-containing vapor deposition precursor itself. These compositions are useful in the deposition of thin films, such as by atomic layer deposition.
