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 ...

Today is the first day of second grade for SteelyKid, and yesterday I took her and her brother, The Pip, to the outdoor pool for an end-of-summer swim. While loading them into the car on the way home, ...

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 ...
