Frictional coefficient during flossing of teeth
Dental Materials, 2018This in-vitro study aimed to develop a technique to measure the frictional forces and determine the frictional coefficient (μ) associated with the rubbing of dental floss against teeth. Incorrect flossing technique and the etiology of grooves at the cementoenamel junction (CEJ) of proximal area of teeth has long been a controversial topic.

Robust Estimation of Road Frictional Coefficient
IEEE Transactions on Control Systems Technology, 2011Vehicle active safety systems stabilize the vehicle by controlling tire forces. They work well only when the commanded tire forces are within the friction limit. Therefore, knowledge of the tire/road friction is important to improve the performance of vehicle active safety systems.

Direct measurements of colloidal friction coefficients
Physical Review E, 2001The time-independent hydrodynamic forces operating between two hard spheres were studied as a function of the interparticle separation r. Two colloids were positioned a distance r apart using a dual-beam optical tweezer similar to that described by Meiners and Quake [Phys. Rev. Lett. 82, 2211 (1999)].

SummaryA summary is presented of information collected on coefficients of friction (rolling and sliding) between rubber tyres and road or runway surfaces. Nearly all the data collected are from tests on automobile tyres and are limited to speeds of about 40 m.p.h.

Coefficient of Friction of Watermelon
Transactions of the ASAE, 1996The static and dynamic coefficients of friction for two watermelon cultivars against six different surfaces were measured at three sliding speeds and three normal forces. The sliding speed, measurement (harvest) date, and type of abrasive surface had a significant effect on both coefficients, except sliding speed did not affect the dynamic coefficient ...

Coefficient of Friction of Human Corneal Tissue
Cornea, 2015A novel property evaluation methodology was used to determine the elusive value for the human corneal coefficient of friction (CoF).Using a microtribometer on 28 fresh human donor corneas with intact epithelia, the CoF was determined in 4 test solutions (≥5 corneas/solution): tear-mimicking solution (TMS) in borate-buffered saline (TMS-PS), TMS in ...
