Webb10 apr. 2024 · The study explores the corrosion mechanisms and kinetics that are related to materials dissolution, oxidation, and diffusion of Ni-based alloys (Hastelloy N and Hastelloy X) and Fe-based alloy (SS316) in molten fluoride salt (LiF-NaF-KF, known as FLiNaK) at 750 °C for various exposure times in Ni crucibles. These three alloys were … WebbAfter 36 h, naproxen was released at 88 and 81% according to r= 0.20 and r= 0.15 hydrogels, respectively, while for r= 0.05 and r= 0.10, up to 12 h was required to reach the maximum release rate. As a result, the poly (NIPAAm-co-γ-PGA-AGE) hydrogels can be considered as a controlled drug release carrier. 30.
