  • Publication number: 20140170328
    Abstract: An electroless plating Ru bath for the deposition of Ru on the surface of a substrate comprises a Ru stock solution and hydrazine as a reducing reagent. Ru layers may be applied, for example, for use in membranes for the separation of hydrogen gas from mixtures of gases or to protect materials from corrosion. An example Ru stock solution comprises Ru chloride, hydrochloric acid, ammonia, nitrite salt, alkali hydroxide, and deionized water. The electroless plating bath may be applied to deposit ruthenium layers onto palladium layers to prepare Pd—Ru composite or alloy membranes or multilayer Pd—Ru composite or alloy membranes. Such membranes have example application to the separation of hydrogen from mixtures of gases.

  • Patent number: 8703232
    Abstract: The present disclosure describes an article and a method of forming a microstructure. The method includes providing a substrate having a structured surface region comprising one or more recessed features with recessed surfaces. The structured surface region is substantially free of plateaus. The method includes disposing a fluid composition comprising a functional material and a liquid onto the structured surface region. The method includes evaporating liquid from the fluid composition. The functional material collects on the recessed surfaces such that a remainder of the structured surface region is substantially free of the functional material.
