Researchers report measuring different friction forces when a carbon nanotube slides along its axis compared to when it slides perpendicular to its axis. The observation could provide a new means for ...

Friction is an intrinsic physical phenomenon to curling. Without it, objects in motion would move endlessly, without slowing down. This would cause many safety-related problems: Cars or trains could ...

Nanotubes and nanowires are promising building blocks for future integrated nanoelectronic and photonic circuits, nanosensors, interconnects and electro-mechanical nanodevices. But some fundamental ...
