Production of Metallic Foam Precursors Using Current‐Activated Pressure‐Assisted Densification
Advanced Engineering Materials, EarlyView.A powder compaction metallurgical method, known as current‐activated pressure‐assisted densification, is applied to enhance the compaction of metal foam precursors. This method improves precursor quality by achieving higher density, lower electrical resistivity, and more uniform pore nucleation in the resulting foams, reducing energy consumption and ...

Structural and electronic properties of grain boundaries in graphite: Planes of periodically distributed point defects [PDF]
, 2008 We report on scanning tunneling microscopy and spectroscopy of grain boundaries in highly oriented pyrolytic graphite. Grain boundaries showed a periodic structure and an enhanced charge density compared to the bare graphite surface.
