(Phys.org)—A small team of researchers at IBM Research–Zürich, has found a new way to measure the friction involved when two planes of highly ordered pyrolytic graphite (HOPG) are moved against one ...

Friction is the enemy of all things mechanical, and without regular maintenance, machinery service life becomes severely reduced until, ultimately, the machines cease to function. Anyone who owns a ...

Structural superlubricity, a state of nearly zero friction and no wear between two contact surfaces under relative sliding, holds immense potential for research and application prospects in ...

Icequake observations were combined with an analytical friction model to measure friction and slip at the bed of an Antarctic ice stream. Friction and slip are found to be highly variable in space and ...

Evaluating tribological properties such as friction coefficients, friction forces, and torques for arbitrary material pairs, with high precision is crucial for multiple areas of research and industry.

A specially equipped Volvo VHD 430 totes a Sideway-force Coefficient Routine Investigation Machine (SCRIM) – to evaluate friction on roadways to determine whether highway improvements could reduce ...

Researchers at Surrey have developed the first low-cost sensor which can accurately measure skin friction drag, using off-the-shelf components. The sensor has primarily been designed for the aerospace ...

Robots may soon mimic the human sense of touch, with advances in flexible tactile detection aiming to endow them with the ability to sense friction and slip. Polymer optical fiber knots are at the ...
