After the pioneering work by Iijima in 1991 [7], recent developments in the field of carbon nanostructured materials, such as Carbon Nanofibers (CNF) and Nanotubes (CNT), have generated tremendous interest particularly towards their application as catalyst supports.
The purity of Ni target material was 99.99%, and at least 99.95% for adhesion metals.

These values of maximum stress are above the range of the material elasticity limit (760-790 N/mm2).
Conversely, the calculated stresses in the outer ring of the 6317 bearing are substantially below the critical values of the material characteristic.

Introduction Iron chromium alloys are extensively investigated for their potential application as interconnect materials in solid oxide fuel cells (SOFCs).
Since the coatings contained organic solvent, the first few hours of oxidation in the furnace result in a weight decrease because of the burn-off of the organic material.
The 1C44Mo20 test alloys was kindly supplied by Sandvik Materials Technology (Sweden); the LSM slurry coatings were provided by Haldor Topsoe A/S (Denmark).
