An article having: a nonconductive fiber and a RuO2 coating. A method of: immersing a nonconductive article in a solution of RuO4 and a nonpolar solvent at a temperature that is below the temperature at which RuO4 decomposes to RuO2 in the nonpolar solvent in the presence of the article; and warming the article and solution to ambient temperature under ambient conditions to cause the formation of a RuO2 coating on a portion of the article. An article having: a nonconductive fiber and a coating. The coating is made by electroless deposition, sputtering, atomic-layer deposition, chemical vapor deposition, or physical vapor deposition.
摘要:
In a system and method for enhancing organic oxidation reactions, an orga reactant is brought in contact with a stable, non-soluble, porous, electronically non-conductive, inorganic solid (reaction enhancer) in a fluidic medium to form a reaction mixture of low ionic strength. The reaction mixture so formed is then subjected to an electrifying force thereby enhancing the chemical reaction. Oxidation reaction products are then collected.

摘要:
A carbon nanopipe comprising a durable graphitizable carbon wall of tunable thickness of about 10-500 nm formed by exposing a silica fiber network to a carbon precursor vapor and thereby depositing a carbon film onto the silica fiber network at a temperature suitable for complete pyrolysis of the carbon precursor and removing the silica fibers. The atmosphere of the step of depositing is controlled by a two-stage gas manifold wherein stage 1 purges the reaction chamber with pure argon and stage 2 introduces the carbon precursor.

摘要:
A photoelectrode is disclosed having a conductive lead and a titania aerogel in electrical contact with the lead. The aerogel is coated with a photosensitive dye. The photoelectrode may be made by forming a film of a titania aerogel paste on a conductive substrate and coating the film with a dye.
摘要:
Increased lithium capacity of defective oxide materials and methods for preparation are described herein. Point defects may be introduced into a metal oxide to increase its lithium ion capacity. Defective metal oxides can be prepared by heating the metal oxide under O2/H2O at elevated temperatures. These increased lithium capacity metal oxides may be suitable for use as high specific energy cathodes in lithium metal and lithium ion batteries.
