The circuit element has a first layer composed of an electrically insulating substrate material and a first electrically conductive material which is in the form of at least one discrete area such that it is embedded in the substrate material and/or is applied to the substrate material. Furthermore, it has a second layer having a second electrically conductive material, and a monomolecular layer composed of redox-active bispyridinium molecules, which is arranged between the first layer and the second layer. The bispyridinium molecules are immobilized on the electrically conductive material which is in the form of at least one discrete area, and make electrical contact with the second electrical material of the second layer. Furthermore, electrically inert molecules are immobilized on the first layer, which molecules form a matrix which surrounds the at least one discrete area with the monomolecular layer composed of bispyridinium molecules.

A polythiophene polymer with high charge-carrier mobilities, a method for fabricating the polymer, and a semiconductor component and an organic field effect transistor including the polymer are provided. The polymer has electrical semiconductor characteristics and includes a backbone formed from thiophene groups.

摘要:
A material is utilized with an electropositive metal. This can be used as post-oxyfuel process for oxyfuel power stations. Here, an energy circuit is realized by the material utilization. An electropositive metal, in particular lithium, serves as energy store and as central reaction product for the conversion of nitrogen and carbon dioxide into ammonia and methanol. The power station thus operates without CO2 emissions.
