Provided herein are composite conductors, characterized by having copper deposits inside the bulk rather than on the outer surface of a non-metallic conductive porous matrix, such as CNT fabric, as well as a process for obtaining the same. The composite conductors provided herein are also characterized by a low specific weight and a high ampacity compared to metal conductors of similar size and shape.

Carbon-nanotubes copper composite conductors

Provided herein is forward osmosis-based water purification process, that includes contacting a solution of a soluble draw agent with a dehydrated insoluble draw agent, separating the now hydrated insoluble draw agent from the now concentrated draw solution, and exerting a stimulus on the hydrated insoluble draw agent for extracting water therefrom, thereby regenerating a dehydrated insoluble draw agent, wherein the osmotic concentration (osmolality) of the insoluble draw agent is greater than the osmotic concentration of the diluted draw solution, and the insoluble draw agent is impermeable to the soluble draw agent.

Apparatus and process for separation of water from dissolved solutes by forward osmosis

Disclosed is a method for activating a surface of metals, such as self-passivated metals, and of metal-oxide dissolution, effected using a fluoroanion-containing composition. Also disclosed is an electrochemical cell utilizing an aluminum-containing anode material and a fluoroanion-containing electrolyte, characterized by high efficiency, low corrosion, and optionally mechanical or electrochemical rechargeability. Also disclosed is a process for fusing (welding, soldering etc.) a self-passivated metal at relatively low temperature and ambient atmosphere, and a method for electrodepositing a metal on a self-passivated metal using metal-oxide source.

Method for passive metal activation and uses thereof

Silicon-oxygen batteries comprising a silicon anode as chemical fuel, an air-cathode for dissociating oxygen and a non-aqueous electrolyte, and applications using the same are provided. The silicon-batteries may utilize air for generating oxygen.

Silicon-air batteries

A novel process of preparing a Grignard reagent is disclosed. The process is effected by electrochemically reacting a Grignard precursor with an electrode which comprises a metal for forming the Grignard reagent, in the presence an electrolyte solution that comprises a room temperature ionic liquid (RTIL). Electrochemical cells and systems for performing the process, and uses thereof in various applications are also disclosed.

Process of preparing Grignard reagent

Silicon-oxygen batteries comprising a silicon anode as chemical fuel, an air-cathode for dissociating oxygen, and an electrolyte, and applications using the same are provided. The silicon-batteries may utilize air for generating oxygen.

A composition that rapidly passivates copper-containing surface to yield a uniform layer of insoluble copper oxide, the composition being useful in chemical-mechanical planarization of copper-containing surfaces is disclosed. The composition is a solution having a pH of equal to or greater than 9 and having an oxidation potential sufficient to oxidize the surface to form non-soluble copper oxides. Also disclosed are methods of making and using the composition.

Copper CMP slurry composition

A method for electrochemical etching of a semiconductor material using positive potential dissolution (PPD) in solutions that do not contain hydrofluoric acid (HF-free solutions). The method includes immersing an as-cut semiconductor material in an etching solution, and positive biasing at atypically highly positive (anodic) potentials, thereby significantly increasing the value of the anodic current density (measured as A/cm) of the semiconductor material. The application of positive biasing at atypically highly positive (anodic) potentials, is combined with specifically controlling and directing illumination on the semiconductor material surface contacted and wetted by the etching solution. This is done for a necessary and sufficient period of time to enable a positive synergistic effect on the rate and extent of etching of the semiconductor material therefrom.
