High temperature thermal stability of innovative nanostructured thin coatings for advanced tooling
منشور في 2014"…The main problem with steel, isthat itexhibits a relatively low hardness (below 10 GPa) which strongly decreases upon annealing above about 600 K.Thus, the majority of modern tools are nowadays coated with hard coatings that increase the hardness, decrease the coefficient of friction and protect the tools against oxidation. …"

Pd nanocrystals encapsulated in MOF-derived Ni/N-doped hollow carbon nanosheets for efficient thermal CO oxidation: unveiling the effect of porosity
منشور في 2023"…The obtained Pd/Ni-MOF-HNC possesses hollow carbon sheets with a great surface area (153.05 m2 g−1), pore volume (0.12 cm3 g−1), rich Pd/Ni-Nx active sites, Ni-metal defects, rich N-content (7.53 at%), mixed Pd/Ni-oxide phases, and uniformly distributed ultra-small Pd nanocrystals (7.03 ± 1.10 nm); meanwhile, Pd/Ni-MOF-NC formed without etching had no porosity and less Ni-metal defects. …"
