With a theoretical model to explore the wear-resistant thermocouple measurement under different environmental conditions

Solid material, in fact, is not as strong as it seems. Usually, each atom vibration is usually around a specific location in the materials. Most aims to define the theoretical model of wear-resistant thermocouple are based on this concept, namely the atoms will not keep its position and they are very far apart.

perovskite recognition through its crystal structure, and in a variety of forms. Their elements can be either molecules, or atoms. Atoms in the molecule vibration, but also the whole molecule can rotate, this means that the movement of the atoms is much more mobile than calculation often assume. Dynamic disorder of wear-resistant thermocouple

show this kind of material called & other atypical behavior; Dynamic disorder of wear-resistant thermocouple & throughout; 。 Wear-resistant thermocouple in the application of environmentally sensitive shows great potential. Good ion conductor materials such as in the fuel cell and battery and thermoelectric application shows a potential in the development of the solid electrolyte.

however, the characteristics of the material is difficult to calculate in theory, and scientists have repeatedly forced to use a arduous experiment.

jonas & middot; Carat Berlin ( 乔纳斯Klarbring) Developed a kind of computing technology, the technology can accurately describe when the wear-resistant thermocouple is heating and phase change happened. John & middot; Crabbe (Lin Johan Klarbring） And his mentor, sergei & middot; SMS ( 谢尔盖看到) Professor in science magazine reports the research results on physical review letters.

bismuth oxide bismuth oxide (they studied Bi2O3) , bismuth oxide is a kind of excellent ion conductor. The current by the ionic conduction of oxides, is the most established wear-resistant thermocouple of all thin oxide ion conductor. Experiments show that it has low conductivity at low temperature, but will experience in heating phase transition into a dynamic disorder with high ionic conductivity phase.

perovskite next

the theoretical calculation and the role of material in the laboratory experiment.

the scientists now plan in other excitant material ( Perovskite, for instance) And materials with high lithium ionic conductivity test the technology. The latter is very interested in for the development of high-performance batteries.

“ Once we have a deep theoretical understanding on the material, and it will provide the possibility of the application for a specific tuning them with more opportunities, & throughout; Johan Klarbring concluded.

the study by the Swedish research council and the Swedish government the support of the strategic initiative in the study area, the initiative functional materials provided by the linkoping university materials science. Recommendation:
