居住在上海的德商麥永剛（Juergen Meyer），2013年以德國財務與風險管理經理的身份來到中國，之後長居上海，在金融及IT領域工作，專注於企業整體獲利與風險管理。最近他與上海夥伴合著《與中國做生意的企業風險管理》一書，詳細剖析在中國經商的逾50種風險。
"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.
