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 Nanotubes Specifications and Properties Carbon Nanotubes, simply CNTs, are allotropes of carbon with a round and hollow nanostructure. These barrel shaped carbon molecules have crucial properties, which are significant for nanotechnology, hardware, optics and other different fields of materials science and innovation. The carbon nanotube’s excellent quality as a strong and firm material laid the basis on many applications. Not to mention carbon nanotubes exceptional heat conductivity, electrical and mechanical properties, Carbon Nanotubes are used as additives to diverse auxiliary materials. In terms of rigidity and flexibility Carbon Nanotubes are the stiffest and strongest materials. These quality outcomes from the covalent sp2 bonds framed between the individual carbon molecules. Unlike Graphene , Carbon Nanotubes are either conductive or semiconducting along the tubular hub. Carbon Nanotubes also have absorption, fluorescence properties. Bulk Carbon nanotubes are util...

Hydroxyapatite Nanopowders and Their Applications

Hydroxyapatite, is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4 ) 3 (OH). Pure hydroxyapatite powder is white. Naturally occurring apatites can, however, also have brown, yellow, or green colorations, comparable to the discolorations of dental fluorosis. Hydroxyapatite Nanopowder/Nanoparticles (50 nm, 99.95+%)  has been widely used as a biocompatible ceramic in many areas of medicine, but mainly for contact with bone tissue, due to its resemblance to mineral bone. In mammals, the skeleton presents a carbonated and partially substituted apatite, based on nanocrystal aggregates, and associated with collagen, building up 3-D structures present in various bone tissue conformations like trabecular or cancellous bone. There has been growing interest in developing bioactive synthetic ceramics that could closely mimic natural apatite characteristics. As mentioned before,  Hydroxyapatite Nanopowder  is the main inorganic constituent of bon...
