A diffusion-barrier-contained Hf-doped (Ni,Pt)Al coating was prepared by firstly composite electroplating and then aluminising. The TEM study of the microstructure showed that Hf serves as a solid solution in (Ni,Pt)Al lattice and forms HfO2 in the H

Bis(p-phenylene)-34-crown-10-based substituted macrocycles bearing a dibenzylammonium side arm form sailboat-shaped self-complexes, in which the arm of the substituted macrocycle sticks into the cavity of the crown ether instead of threading into it.

Two Pt modified NiCoCrAlY coatings were prepared with the Pt-rich zone located at the coating surface (NiCoCrAlY + Pt) or at the substrate/coating interface (Pt + NiCoCrAlY). The microstructures of two coatings were studied with TEM. The hot corrosio
