摘要： Methods of obtaining a titanium dioxide nanofilm or microfilm are provided herein. A pure sheet of titanium is irradiated with a CO2 laser to produce the titanium dioxide nanofilm or microfilm. The titanium sheet can optionally be doped with an oxide, such as barium oxide. The method produces titanium dioxide nanofilms or microfilms that can be produced in more than one phase, such as a rutile phase, an anatase phase, or both combined. The titanium dioxide nanofilms or microfilms can be directly fabricated with high purity without any further processing.

摘要： Methods of patterning semiconductor devices comprising selective deposition methods are described. A blocking layer is deposited on a metal surface of a semiconductor device before deposition of a dielectric material on a dielectric surface. Methods include exposing a substrate surface including a metal surface and a dielectric surface to a heterocyclic reactant comprising a headgroup and a tailgroup in a processing chamber and selectively depositing the heterocyclic reactant on the metal surface to form a passivation layer, wherein the heterocyclic headgroup selectively reacts and binds to the metal surface.

摘要： A problem to be solved by the present invention is to provide a method for forming a multilayer coating film, the method being capable of achieving excellent finished appearance and excellent corrosion resistance without affecting electrodeposition coatability even when a part or all of the water-washing step is omitted after chemical conversion treatment, and to provide a coated article. The invention provides a method for forming a multilayer coating film, comprising forming a chemical conversion coating film and an electrodeposition coating film on a metal substrate by Step 1 of immersing a metal substrate in a chemical conversion treatment solution to form a chemical conversion coating film, and Step 2 of omitting a part or all of the water-washing step, and performing electrodeposition coating on the metal substrate using a cationic electrodeposition coating composition to form an electrodeposition coating film, wherein when the electrodeposition coating is performed in Step 2, the solution adhered to and/or deposited on the metal substrate has an electrical conductivity of less than 10,000 μS/cm.
