"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.
未来，产品创新的核心标准，将集中在审美力、产品力、渠道力、营销力、运营力、文化力六个方面。很多创业者不适合做大连锁，让他们开1万家店会很痛苦，但让他们一年打造一个小而美品牌能做得很好。王繁星的创始人说：“不让我做品牌，我会睡不着觉。”这就是创新时代的创业者特质。
