Magnetic Response of Hydrothermally Prepared Self-Assembled Co3O4 Nano-platelets
In the present communication, we report a strong ferrimagnetic behavior of self-assembled Co3O4 nano-platelets, which most likely originates from the intrinsic spin structure of the unique Co3O4 structure. The mi...

Effect of Cu content on the mechanical reliability of Ni/Sn-3.5Ag system
Copper was supplied to Sn–3.5Ag by electroplating Cu/Ni double under-bump metallization (UBM), and the amount of Cu was controlled by varying the Cu UBM thickness. Supposed Cu contents in the solder were; 0.2,...
