The contact of a steel electrode with water dispersion medium in an open-air system leads to the development of various polymorphic iron oxides and oxyhydroxides on the steel surface. Whereas the usage of distilled water causes the obtaining of Fe(II)-Fe(III) layered double hydroxides (green rust) as a primary mineral phase, but in the presence of inorganic 3d-metal water salt solutions, mixed ...

We focus on the development of a remote temperature sensing technology, i.e., an optical laser-based sensor, using thermographic phosphors for medical applications, particularly within an electromagnetically hostile magnetic resonance imaging (MRI) environment. A MRI scanner uses a strong magnetic field and radio waves to generate images of the inside of the body. The quality of the image impro...

The La modified bismuth ferrite perovskite Bi0.6La0.4FeO3 (BLF) is prepared by cost-effective high solid-solution casting technique. Formation of composite checked through X-ray diffraction and also notable that there phase transition from rhombohedral (R3c) to orthorhombic (Pbnm). average crystalline size (DSC) mechanical lattice strain are 63.8 nm 0.147% respectively as calculated Williamson-...

Abstract Lanthanum strontium cobalt ferrite (LSCF) is an appreciable cathode material for solid oxide fuel cells (SOFCs), and it has been widely investigated, owing to its excellent thermal chemical stability. However, poor oxygen reduction reaction (ORR) activity, particularly at a temperature of ⩽ 800 °C, causes setbacks in achieving peak power density > 1.0 W·cm −2 , limiting application ...
