摘要: A pharmaceutical composition containing a metal oxide coated particle comprising 1) an amorphous solid dispersion (ASD) core containing an active pharmaceutical ingredient (API) and a polymer; and 2) a metal oxide coating, and the method of making said metal oxide coated particle by atomic layer deposition (ALD). The metal oxide coated particle is useful because it prevents the ASD from crystallization and helps maintain the ASD in an amorphous form.

摘要: A method of forming and controlling air gaps between adjacent raised features on a substrate includes forming a silicon-containing film in a bottom region between the adjacent raised features using a flowable deposition process. The method also includes forming carbon-containing material on top of the silicon-containing film and forming a second film over the carbon-containing material using a flowable deposition process. The second film fills an upper region between the adjacent raised features. The method also includes curing the materials at an elevated temperature for a period of time to form the air gaps between the adjacent raised features. The thickness and number layers of films can be used to control the thickness, vertical position and number of air gaps.

摘要: Using the systems and methods discussed herein, CMAS corrosion is inhibited via CMAS interception in an engine environment and/or is prevented or reduced by the formation of a metal oxide protective coating on a hot engine section component. The CMAS interception can occur while the engine is in operation in flight or in a testing or quality control environment. The metal oxide protective coating can be applied over other coatings, including Gd-zirconates (GZO) or yttria-stabilized zirconia (YSZ). The metal oxide protective coating is applied at original equipment manufacturers (OEM) and can also be applied in-situ using a gas injection system during engine use in-flight or during maintenance or quality testing. The metal oxide protective coating contains a rare earth element, aluminum, zirconium, chromium, or combinations thereof and can have a thickness from 1 nm to 3,000 nm.
