"Tuning frictional behavior on the fly has been a long-standing engineering dream," said co-author Katia Bertoldi of Harvard University. "This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.” In addition, the dynamics revealed by these results are similar to those of tectonic faults and thus give scientists a new model for the mechanics of earthquakes, according to their new paper published in the journal Nature.
"I told him not to participate. Things can happen at protests," she told the BBC. But Shreeyam was deeply engaged with politics, his father said. "He said corruption had hollowed out [Nepal]. He was far more informed than I was."
