Study on dealloying of Ag40Zn60 alloy
Procedia Engineering, 2012 AbstractThe solid solution of Ag40Zn60 alloy can exhibit phase structure of hcp (-phase and body-centered cubic (-phase at room temperature. The alloy was dealloyed at the potential of 0.6V in 0.1M H2SO4 solution. The result shows that corrosion potential and critical potential decreases with increasing concentration of H2SO4 solution. After dealloying,

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A one‐step gas‐phase synthesis directly assembles amorphous Si nanoparticles with few‐layer graphene heterostructures via in‐flight mixing. Compositions with only 15 wt.% FLG deliver ~2800 mAh g−1 (Si + FLG) at 0.05 C and retain ~1400 mAh g−1 after 100 cycles at a high cycling rate of 1 C, enabled by a percolated, strain‐buffering graphene network that
