Nb and Cu co-doped (La,Sr)(Co,Fe)O: a stable electrode for solid oxide cells.

Solid oxide cells (SOCs) are electrochemical devices that convert the chemical energy of a fuel into electricity. With regard to electrodes, the development of materials with mixed conduction properties is a key issue for improving the performance of SOCs at high temperatures. New Cu and Nb co-doping La Sr Fe Co O (LSCF) materials were studied as electrode materials on yttria-stabilized zirconia (YSZ) supports.

On the texture, phase and tensile properties of commercially pure Ti produced via selective laser melting assisted by static magnetic field.

Tensile strength and ductility of Selective Laser Melting (SLM) processed commercially pure Ti (CP-Ti) were simultaneous enhanced by preforming the melting/solidification processes under Static Magnetic Field (SMF). The effects of SMF on microstructure and tensile properties were examined. The SMF-SLMed CP-Ti sample presents a microstructure of fine acicular martensitic α'-Ti and lath-shaped α-Ti.
