"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.
Stepping into the role, he recognized that the company needed a reset, and set off to rebuild trust and focus among his staffers. Soon enough, ideas progressed faster, team collaboration improved, and employees were striving for even greater success, Rascoff said.，这一点在旺商聊官方下载中也有详细论述
