Ligament coarsening in nanoporous gold: Insights from positron annihilation study

R. N. Viswanath, V. A. Chirayath, and R. Rajaraman et al.

Positron lifetime experiments, coupled with scanning electron microscopy studies, have been used to follow the coarsening of the ligaments of nanoporous Au (np-Au), prepared by electrochemical dealloying of Ag75Au25. Positron lifetime measurements in the as-prepared np-Au indicate two lifetime com ... [Appl. Phys. Lett. 102, 253101 (2013)] published Mon Jun 24, 2013.

Magnetic nanoparticles of core-shell structure for recoverable photocatalysts

Ying Jing, Shi-Hai He, and Jian-Ping Wang

Si doped iron-iron oxide core-shell magnetic nanoparticles are presented in this paper for photocatalysis applications. The nanoparticles were fabricated by a gas phase method with control of small size. Enhanced optical absorption was observed in them compared to the ones without Si, particularly ... [Appl. Phys. Lett. 102, 253102 (2013)] published Mon Jun 24, 2013.
