摘要:
Disclosed are a method for adjusting the pore size of a porous metal material and the pore structure of a porous metal material. The method comprises: permeating at least one element into the surface of the pores of the material to generate a permeated layer on the surface of the pores, so that the average pore size of the porous material is reduced to within a certain range, thus obtaining a pore structure of the porous metal material having the pores distributed on the surface of the material and the permeated layer provided on the surface of the pores.

摘要:
The present invention comprises artificial nucleic acid constructs comprising a bidirectional promoter having minimal promoter and a common promoter, wherein said minimal promoters is operably linked to said common promoter, in opposite orientation to said common promoter, and 5′ to said common promoter. Those artificial nucleic acid constructs, wherein said bidirectional promoter further comprises at least one gene operably linked to said minimal promoter and said common promoter are preferred.
