The present invention relates to novel chromatography stationary phases comprising non-polysaccharide carbohydrate polyethers and methods for their preparation. Particularly, the invention relates to chromatography stationary phases comprising said carbohydrate polyethers and more particularly to chiral stationary phases. Also, since the carbohydrate polyethers of the present invention can be conveniently prepared with controlled functionality, molecular weights and polydispersity indices as well as controlled microstructure, tertiary structure stationary phases prepared from these polymers can be conveniently modified or custom synthesized to accommodate specific separation requirements.

Carbohydrate polyethers for chromatographic media

An electrochemical cell with an alkali metal containing anode having high discharge capacity, charge efficiency and low self-discharge. The addition of at least one nitramide or dinitramide salt of a metal cation to the electrochemical cell electrolyte unexpectedly lowers first cycle irreversible capacity, adds higher cycle life, lowers self-discharge and beneficially addresses several additional degrees of freedom with respect to electrolyte solvent selection while providing higher charge capacity. Additives include the lithium metal salts of nitramide or dinitramide, and the electrolyte consists essentially of a lithium metal salt dissolved in a at least one of an aqueous solvent, molten salt solvent system and a non-aqueous solvent mixture of at least one of organic ethers, esters, carbonates, acetals.

An adsorbent material fabricated into a reinforcement-free, self-supported coherent thin sheet and configured for use as a parallel passage contactor element in adsorption/separation applications with gases and liquids is disclosed. The adsorbent sheet material is obtained by enmeshing fine adsorbent particulates in a polymer binder. Particulates include but are not limited to carbon particles, inorganic oxides particles, or ceramic particles, or synthetic polymer resin particles. The adsorbent sheet advantageously contains a large volume percentage of active adsorbent particles. The parallel passage contactor device fabricated from the adsorbent sheet material is characterized by minimal mass transfer resistance and better separation efficiency expressed as height equivalent to a theoretical plate, while it maintains most of the adsorptive properties of the starting particulates, and can be used in gas separation applications with short adsorption cycles, such as rapid pressure swing adsorption, rotary concentrators, rapid electric swing adsorption.

An apparatus for depositing synthetic diamond on a surface of a substrate includes a deposition chamber and a cooling block having a surface in the deposition chamber that is cooled by heat exchange. The substrate is supported from the cooling block so that the bottom surface of the substrate is spaced from the cooling block surface by a gap, and a gas is provided in the deposition chamber and in the gap, the gas comprising at least 30 percent hydrogen gas. A plasma deposition system forms in the chamber a plasma containing hydrogen gas and a hydrocarbon gas for depositing synthetic diamond on the top surface of the substrate.

A deposition target medium is disclosed for use in CVD of a diamond film wherein a hydrocarbon gas and atomic hydrogen are utilized in depositing the diamond film on the deposition target medium, which comprises a substrate having a Young's modulus of less than 50 GPa; and a coating on said substrate, said coating comprising a binder and diamond grit, said binder comprising a glass-forming oxide.

Deposition target medium for diamond film deposition

A plasma jet CVD system includes gas injectors and a stand-off ring. The gas injectors have outlet holes preferably flared to approach the expansion angle of the injected jet, thereby keeping the holes substantially free from entrained atomic hydrogen. The injectors are arranged counter-rotational to the swirl of the primary jet, providing a more uniform mixture of hydrocarbons and atomic hydrogen. The stand-off ring provides vents for cooler gases to enter the nozzle, thereby decreasing the overall temperature of the injectors and decreasing the temperature gradient experienced by the injectors, thereby preventing injector cracking. In addition the vents reduce shear, thereby increasing jet velocity and increasing the deposition rate for the coating. In addition, a new method of injector design permits optimal mixing characteristics to be obtained across various recipes whereby the ratio of the mass flux of the primary flow of the jet to the mass flux of the injected flow from the downstream injectors is kept constant.

A method for producing a diamond film is disclosed, which comprises the steps of providing a substrate having a Young's modulus of less than 50 GPa; applying a coating material comprising a glass-forming oxide binder and diamond grit to the substrate; and depositing said diamond film on said coating by CVD.

Diamond film deposition

A method is disclosed for depositing diamond film, including the following steps: providing an environment comprising hydrogen gas and a hydrocarbon gas; dissociating hydrogen gas of the environment by dielectric barrier discharge to obtain atomic hydrogen; and providing a deposition surface in the environment and implementing diamond deposition on the deposition surface from the hydrocarbon gas, assisted by the atomic hydrogen. In a preferred embodiment, the atomic hydrogen is transported by molecular diffusion from its dissociation site to the deposition surface.
