"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.,推荐阅读im钱包官方下载获取更多信息

The US is a key market though, second only to China by some counts. Last year, Vigloo opened an office in LA. The firm wants to target American women who they believe will spend more than their Korean counterparts.
