US Patent - Methods For the Production of Cathode Materials for Lithium Ion Batteries
______
The present discloure provides methods for producing cathode materials for lithium ion betteries. Cathode materials that contain manganese are emphasized. The process includes reactions of carboxylate precursors of nickel, manganese and/or cobalt and lithiation with a lithium precursor. The carboxylate precursors are made from reactions of pure metals or metal compounds with carboxylic acids. The manganese precursor contains bivalent manganese and the process controls the oxidation state of manganese to avoid formation of higher oxidation states of manganese.

US Patent - Hydrogen Storage and Delivery System
______
A method for storing and delivering hydrogen gas is described. The method includes reacting a chemical hydride with water in the presence of a synergist. The synergist advances the extent of reaction of the chemical hydride with water to increase the yield of hydrogen production. The synergist reacts with byproducts formed in the reaction of the chemical hydride with water that would otherwise inhibit progress of the reaction. As a result, a greater fraction of hydrogen available from a chemical hydride is released as hydrogen gas.

US Patent - Synthesis of Higher Germanes and Higher Silanes
______
The Present invention provides an efficient method of drying higher germanes and higher silanes to prevent their further hydrolysis. Another synthetic process involves the reaction of germanium oxide, borohydride and boron oxide with water. Still another process comprises hydrolyzing the Si1-xGex alloy with a very dilute base solution. The method enable production of higher germanes from a wide range of germanium-starting materials, including germanium byproducts, impure germanium compounds, and waste products generated in the plasma deposition of thin films containing germanium.

US Patent - Cathode Materials for Lithium Ion Batteries
______
The present disclosure relates to cathode materials for lithium ion bateries. Most particularly, the present disclosure relates to methods for producing transition metal oxide materials. Most particularly, the present disclosure relates to methods for preparing oxide materials with layers of lithium that alternate with layers of oxides of nickel, manganese, and/or cobalt("NMC"), or nickel and manganese without cobalt("NM"), or nickel, manganese and/or cobalt and/or other elements. The materials feature a controlled degree of mixing of transition metal cations in the lithium layers and minimization of the presence of Mn4+ and higher oxidation states of manganese during the synthesis.

US Patent - Germane
______
A method for the production of germane includes reacting an oxide of germanium and/or a non-oxide of germanium compound with a borohydride in a base solution. The method permits production of germane from impure germanium-containing starting materials. Catalysts for the reaction include transition metal elements, as well as oxides, hydroxides, halides, and other complexes or compounds of transition metals. Application of heat increases the efficiency of the catalyst. The methods also include production of germane through oxidation of pure or impure oxide or non-oxide of germanium.
