Expert Reviews

Dr. Myron Rubenstein Ph.D (Polytechnic University of Turin, Italy)

Lanthanum strontium magnetite nanoparticles for fuel cell cathode applications utilizing solid-state processing to produce single-phase perovskite structures with various doping levels and surface areas (SSA) for use in thin-film layers. This material is commonly used as a cathode material in commercially produced solid oxide fuel cells (SOFCs) because it has a high electrical conductivity at higher temperatures, and its thermal expansion coefficient is well-matched with yttria-stabilized zirconia (YSZ), a common material for SOFC electrolytes.

Dr. Huojin Chan  (University of Science and Technology of China, Hefei, Anhui, China)

Lanthanum strontium magnetite nanoparticles are white spherical high surface area metal particles. Lanthanum strontium manganite Nano-particles are typically 10-30 nanometers (nm) with specific surface area (SSA) in the 130-150 m2/g range.  Lanthanum strontium magnetite nanoparticles  (LSM or LSMO) is an oxide ceramic material with the general formula La1−xSrxMnO3, where x describes the doping level. LSM has a rich electronic phase diagram, including a doping-dependent metal-insulator transition, paramagnetism, and ferromagnetism. The existence of a Griffith phase has been reported as well. It has a perovskite-based crystal structure, which has the general form ABO3. It is highly electronically conductive and has proven long term stability

Lanthanum strontium magnetite nanoparticles are black in color and have a density of approximately 6.5 g/cm3. The actual density will vary depending on the processing method and actual stoichiometry. LSM is primarily an electronic conductor, with a transference number close to 1. In other words, the material consists of lanthanum manganite with some of the lanthanum atoms substitutionally doped with strontium atoms. The strontium (valence 2+) doping on lanthanum (valence 3+) introduces extra holes in the valence band and thus increases electronic conductivity.

Dr. Bruce Perrault Ph.D (Georgia Institute of Technology (Georgia Tech), USA)

Lanthanum strontium magnetite nanoparticles are highly electronically conductive and have proved long term stability. Lanthanum strontium manganite belongs to a class of "A" site and "B" site doped perovskite structures with these properties. It is show the colossal magnetoresistance (CMR) effect and is also an observed half-metal for compositions around x=0.3. Lanthanum strontium magnetite nanoparticles will partially sinter to form well-defined necks and open gas paths to permit simultaneous gas and electrical transfer.
