A highly hydrophobic melamine sponge with outstanding magnetic response and fire resistance has been fabricated by a simple two-step method including spontaneous deposit of Fe3O4 nanoparticles onto the sponge and dip coating of lignin. The obtained sponge, combining excellent self-cleaning, compressibility with high porosity, can be magnetically driven to absorb the oils from polluted water. The oil-absorbed...
Ag-alloy wire has been recognized to be a good candidate for interconnect in light-emitting diode (LED) technology. This study employed fine Ag-alloy wires bonded on Al-Si pad to investigate their failure mechanism under current stressing of 8×104A/cm2 at ambient temperature of 150°C and 175°C, respectively. We report a novel polarity effect that the spontaneous whisker growth of Ag near bonded area...
