"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.

He decided to create a new kind of visual communications company, called SpeedPro. The vision was simple but ambitious: Don’t just print, be the last mile of visual marketing. Make a brand impossible to ignore — on walls, windows, floors, vehicles, and every surface a customer might see. The tagline is: “Great. Big. Graphics.”
