Lanthanum Strontium Manganate Sputtering Targets and Applications

Lanthanum Strontium Manganate (La0.7Sr0.3MnO3) Sputtering Target (Size:1'' ,Thickness:0.250'' , Purity: 99.9%) is an oxide ceramic material with the general formula La1−xSrxMnO3, where x describes the doping level.
Lanthanum Strontium Manganate (La0.7Sr0.3MnO3) Sputtering Target has a perovskite-based crystal structure, which has the general form ABO3. In the crystal, the 'A' sites are occupied by lanthanum and strontium atoms, and the 'B' sites are occupied by the smaller manganese atoms. In other words, the material consists of lanthanum manganite with some of the lanthanum atoms substitutionally doped with strontium atoms. The strontium doping on lanthanum introduces extra holes in the valence band and thus increases electronic conductivity.
This material is commonly used as a cathode material in commercially produced solid oxide fuel cells because it has a high electrical conductivity at higher temperatures. Also, Lanthanum Strontium Manganate cathodes used in solid oxide fuel cells have exhibited enhanced catalytic activity after polarization.
Now let’s see that solid oxide fuel cells and how Lanthanum Strontium Manganate (La0.7Sr0.3MnO3) Sputtering Target is used in this area. Solid oxide fuel cells offer an efficient means to convert chemical energy to electricity, with potential applications in transportation, distributed generation, remote power, defense, and many others. An individual solid oxide fuel cell is composed of a fully dense solid electrolyte, a porous cathode or air electrode, and a porous anode or fuel electrode. Fuel cell stacks consist of individual cells that are joined by electrical interconnect plates, and operate in the temperature range of 700–1000 oC. Below you may see the schematic of solid oxide fuel cell with associated reactions. In this system lanthanum strontium manganate most often serves as anode.

Carbon Nanotube Threads

Since its discovery, carbon nanotube (CNT) has attracted many interests in different technology fields due to its extraordinary properties. Properties such as, high strength, great electrical and thermal conductivity, light weight and flexibility made CNT one of the best materials for wide range of applications. However, from its name it can be understood that CNT is a nanoscale material which is very small to be applied for the production of daily products. Researchers all around the world are working on finding methods and techniques which could produce new materials with the extraordinary properties of CNT. Image retrieved from:  https://worldindustrialreporter.com/strong-light-flexible-carbon-nanotubes-threads-with-ultrahigh-conductivity/ One of these research is focusing on the production of high strength threads that can be used in the manufacturing of fabrics, cables and ropes. An international group of scientists were able to produce a flexible conductive thread th...

Multi Walled Carbon Nanotube Dispersions

Carbon nanotubes (CNTs)  have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product. Figure: Single Walled Carbon Nanotube (SWCNT) It ha...
