Partially alloyed copper powder
Abstract Generally copper-based sintered materials are manufactured by compacting and sintering either a mixture of copper powder and other metal powders, or atomized alloy powders. However, the mixed powder is easy to segregate and the alloyed powder is inferior in compactibility.

Josephson squelch filter for quantum nanocircuits
We fabricated and tested a squelch circuit consisting of a copper powder filter with an embedded Josephson junction connected to ground. For small signals (squelch-ON), the small junction inductance attenuates strongly from DC to at least 1 GHz, while ...
