70383 results about "Inorganic chemistry" patented technology

Inorganic chemistry deals with the synthesis and behavior of inorganic and organometallic compounds. This field covers all chemical compounds except the myriad organic compounds (carbon-based compounds, usually containing C-H bonds), which are the subjects of organic chemistry. The distinction between the two disciplines is far from absolute, as there is much overlap in the subdiscipline of organometallic chemistry. It has applications in every aspect of the chemical industry, including catalysis, materials science, pigments, surfactants, coatings, medications, fuels, and agriculture.

Ruthenium containing layer deposition method

An exemplary apparatus and method of forming a ruthenium tetroxide containing gas to form a ruthenium containing layer on a surface of a substrate is described herein. The method and apparatus described herein may be especially useful for fabricating electronic devices that are formed on a surface of the substrate or wafer. Generally, the method includes exposing a surface of a substrate to a ruthenium tetroxide vapor to form a catalytic layer on the surface of a substrate and then filling the device structures by an electroless, electroplating, physical vapor deposition (PVD), chemical vapor deposition (CVD), plasma enhanced CVD (PECVD), atomic layer deposition (ALD) or plasma enhanced ALD (PE-ALD) processes. In one embodiment, the ruthenium containing layer is formed on a surface of a substrate by creating ruthenium tetroxide in an external vessel and then delivering the generated ruthenium tetroxide gas to a surface of a temperature controlled substrate positioned in a processing chamber. In one embodiment, a ruthenium tetroxide containing solvent formation process is used to form ruthenium tetroxide using a ruthenium tetroxide containing source material. In one embodiment, of a ruthenium containing layer is formed on a surface of a substrate, using the ruthenium tetroxide containing solvent. In another embodiment, the solvent is separated from the ruthenium tetroxide containing solvent mixture and the remaining ruthenium tetroxide is used to form a ruthenium containing layer on the surface of a substrate.

Modified polymers prepared with lanthanide-based catalysts

InactiveUS6977281B1Active polymerLanthanide
A method for preparing a functionalized polymer comprising the steps of preparing a pseudo-living polymer by polymerizing conjugated diene monomer with a lanthanide-based catalyst, where said pseudo-living polymer is characterized by having greater than about 85 percent of the polymer in the cis microstructure and less than about 3 percent of the polymer is in the 1,2- or 3,4-microstructure, and reacting the pseudo-living polymer with at least one functionalizing agent defined by the formula (I) or (II)
where Z is a substituent that will react or interact with organic or inorganic fillers; R1 is a single bond or a divalent organic group; R2 is a monovalent organic group or a divalent organic group that forms a cyclic organic group with R13 or R14; R3 is a single bond, a divalent organic group, or a trivalent organic group that forms a cyclic organic group with R4 or R5; R13 is a single bond, a divalent organic group, or a trivalent organic group that forms a cyclic organic group with R2 or R14; R4 is a monovalent organic group or a divalent organic group that forms a cyclic organic group with R3 or R5; R14 is a monovalent organic group or a divalent organic group that forms a cyclic organic group with R2 or R13; and R5 is a monovalent organic group or a divalent organic group that forms a cyclic organic group with R3 or R4; with the proviso that each group attached to the imino carbon is attached via a carbon atom and R1, R2, R3, R4, R5, R13, R14 and Z are substituents that will not protonate a pseudo-living polymer.

Electrode structure for lithium secondary battery and secondary battery having such electrode structure

In an electrode structure for a lithium secondary battery including: a main active material layer formed from a metal powder selected from silicon, tin and an alloy thereof that can store and discharge and capable of lithium by electrochemical reaction, and a binder of an organic polymer; and a current collector, wherein the main active material layer is formed at least by a powder of a support material for supporting the electron conduction of the main active material layer in addition to the metal powder and the powder of the support material are particles having a spherical, pseudo-spherical or pillar shape with an average particle size of 0.3 to 1.35 times the thickness of the main active material layer. The support material is one or more materials selected from a group consisting of graphite, oxides of transition metals and metals that do not electrochemically form alloy with lithium. Organic polymer compounded with a conductive polymer is used for the binder. There are provided an electrode structure for a lithium secondary battery having a high capacity and a long lifetime, and a lithium secondary battery using the electrode structure and having a high capacity, a high energy density and a long lifetime.
