Robots acting as macroscale analogs of active nanoparticles stop moving through friction alone, revealing a self-sustained ...

Friction force microscopy (FFM) of materials with well-defined crystalline surfaces is interpreted within the framework of the Prandtl–Tomlinson (PT) model. This model portrays the interaction with a ...

July 29 (UPI) -- SpaceX scrubbed a static fire test for a Falcon 9 rocket that will carry the Crew-11 team to the ...

A new mouse study of spatial memory suggests that the brain's representation of places "drifts" over time. Memories of places "drift" across the brain as they are carried by different sets of neurons ...

Robot grasping with deformable gripper jaws results in nonplanar surface contacts if the jaws deform to the nonplanar local geometry of an object. The frictional force and torque that can be ...

Friction between meshing gears is one of the principal exciting sources of vibration in gears. Numerous literature have been devoted to investigate the influence of friction on the system. In this ...

Solid-state lubrication at the micro- and nanoscale poses challenges for high-performance microelectromechanical systems and space mechanisms, as conventional liquid lubricants are impractical.
