We demonstrate a generic approach for the synthesis of single-crystal complex oxide nanostructures of various structure types, such as perovskites, spinels, monoclinic, corundum, CaF(2) structured, tetragonal, and even metal hydroxides. The method is based on a reaction between a metallic salt and a metallic oxide in a solution of composite-hydroxide eutectic at approximately 200 degrees C and ...

In order to increase the efficiency and working life of mettalic interconnects used in solid oxide fuel cells, protective coatings with high electrical conductivity are used. In this study, AISI 430 ferritic stainless steel was coated in a cobalt-base pack mixture by pack cementation. The effect of oxide thickness on the area specific resistance (ASR) was investigated by applying isothermal ox...

Because of its superior properties, stainless steel has been widely used for many applications. Nonmetallic inclusions can influence the quality products. A set samples was to track response inclusion composition during processing a heat titanium-bearing 18% chromium steel, from deoxidation after decarburization, solidified slab. The oxide responded as expected additions deoxidizers and calcium...
