bioassay-based results are not always congruent, and conventional methods generally underestimate the effects. Likewise, the choice of reference substance (metals or organics) influences the quantification of impact. Appropriate batteries of biological assays could therefore be utilized to complement LCA (...
The $\text{ Mn }$ have a positive charge compared to other metals. Thus it is not easy for the manganese to donate its electron density to the antibonding orbitals. Therefore, $\text{ Mn }$ would form a weak metal –carbonyl bond. ...
35 35 548 describes a method for preparing a an MCrAlY coating. By galvanic dispersion deposition, a metal matrix is produced of Ni or Co having intercalated particles made of CrAlY. Upon subsequent tempering, the actual protective layer is then created. SUMMARY An example embodiment of the ...
