With the extensive applications of the Sc element in superconducting materials [1], as well as in automotive [2], aerospace, military [3], fluorescence [4] and solid oxide fuel batteries [5,6,7,8], the requirements for the quality of scandium or its alloys are also increasing. However,...
Thermal barrier coatings are currently used, in conjunction with air cooling, to prolong the life of metallic “hot-section” Ni-based super alloy components used in military and civilian aircraft engines with an estimated annual market size of about $1.5 billion. The life of state-of-the-art...
Since the damage did not show signs of military or other human involvement, and, in any case, was too excessive, he argued that repeated seismic activity might have been responsible. E. Schaeffer was not taken seriously in 1948, but since then natural scientists have found widespread and ...
