Described herein is an etching solution suitable for the selective removal of TiSiN over hafnium oxide from a micro-electronic device, which consists essentially of: water; at least one alkaline ammonium compound selected from the group consisting of ammonium hydroxide, a quaternary ammonium hydroxide, ammonium fluoride, and a quaternary ammonium fluoride; at least one peroxide compound; a water-miscible organic solvent; at least one nitrogen containing compound selected from the group consisting of a C.sub.4-12 alkylamine, a polyalkylenimine, and a polyamine; and optionally at least one chelating agent.

Device for producing energy by nuclear fission, and methods of using same. The device comprises a core container of a core container material, which core container encloses an inner tubing of an inner tubing material. The inner tubing and/or the core container has(have) an inlet and an outlet. The device also comprises a molten fuel salt with a fissionable material and a molten moderator salt comprising metal hydroxide(s), metal deuteroxide(s) or a combination thereof and a redox-element having a reduction potential, which is larger than that of the inner tubing material or of the inner tubing material and the core container material. The molten moderator salt is located in the core container, and the molten fuel salt is located in the inner tubing. Alternatively, the molten fuel salt is located in the core container, and the molten moderator salt is located in the inner tubing.

A corrosion-resistant coating on an aluminum-containing substrate such as an aluminum substrate, an aluminum alloy substrate (e.g., AA 2024, AA 6061, or AA7075), or other aluminum-containing substrate includes a corrosion inhibitor-incorporated ZnAl layered double hydroxide (LDH) layer and a sol-gel layer. A zinc salt and a corrosion inhibitor (e.g., a salt of an oxyanion of a transition metal such as a vanadate) is dissolved to form a zinc-corrosion inhibitor solution, and the substrate is immersed in or otherwise contacted with the solution to form the corrosion inhibitor-incorporated ZnAl LDH layer on the substrate. A sol-gel composition is applied on the corrosion inhibitor-incorporated ZnAl LDH layer of the substrate to form a sol-gel layer, and the sol-gel layer is cured.
