"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.

在西贡，杜耀豪寻访二舅时得知，他在越南彼时的生活异常艰辛，“不能做生意，全是合作社，找工作也很困难”。他因偷渡在1976年和1977年两次坐牢，第一次在黑暗里关了一个月，没有灯，没有太阳；第二次关了一年，虽要劳动但相对自由。，详情可参考91视频
