Abstract: A method for producing aluminum oxide is provided. The method uses an aluminum-oxide-forming agent containing a partially hydrolyzed aluminum alkyl compound containing an aluminum trialkyl or a mixture thereof, and a solvent. It is thus possible to produce an aluminum oxide thin film or aluminum oxide particles on or in a substrate that is not resistant to polar solvents. A method of producing a polyolefin-based polymer nanocomposite containing zinc oxide particles or aluminum oxide particles using a solution containing a partially hydrolyzed zinc alkyl or a solution containing a partially hydrolyzed aluminum alkyl is also provided. The polyolefin-based polymer nanocomposite contains a polyolefin substrate and zinc oxide particles or aluminum oxide particles, and does not contain a dispersant. The zinc oxide particles or aluminum oxide particles have an average particle size of less than 100 nm.

Abstract: Methods of forming two-dimensional transition metal dichalcogenide sheets are provided. The methods include adding a cross-linking agent to an activating agent to form a solution and mixing a two-dimensional transition metal dichalcogenide with the solution to form a mixture. The methods also include adding a cleaving agent to the mixture to form one or more contiguous sheets of transition metal dichalcogenide.

Abstract: A pulverulent cathode material contains at least one mixed oxide containing the metal components Li, at least one further metal component selected from the group consisting of Mn, Ni and Co. The pulverulent cathode material is produced by a process in which an ammonia-containing aerosol containing metal compound of the metal components is converted in a high-temperature zone of a reaction space and then the solids are removed.
