An international team has discovered a simple and environmentally friendly way to power the next generation of self-charging electronics. The work is published in Nano Energy.
Perhaps few physical concepts have received less attention relative to their importance than friction. Learning the 'effective' notions of static and sliding friction, students of mechanics can easily ...
