摘要: In one implementation, a method of depositing a material on a substrate is provided. The method comprises positioning an aluminum-containing substrate in an electroplating solution, the electroplating solution comprising a non-aqueous solvent and a deposition precursor. The method further comprises depositing a coating on the aluminum-containing substrate, the coating comprising aluminum or aluminum oxide. Depositing the coating comprises applying a first current for a first time-period to nucleate a surface of the aluminum-containing substrate and applying a second current for a second time-period, wherein the first current is greater than the second current and the first time-period is less than the second time-period to form the coating on the nucleated surface of the aluminum-containing substrate.

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.
