Nano-friction behavior of phosphorene

Nanotechnology, 2017
Nano-friction of phosphorene plays a significant role in affecting the controllability and efficiency of applying strain engineering to tune its properties. So far, the friction behavior of phosphorene has not been studied. This work studies the friction of single-layer and bilayer phosphorene on an amorphous silicon substrate by sliding a rigid tip ...

CHAOTIC BEHAVIOR OF FRICTION FORCE

International Journal of Bifurcation and Chaos, 1992
Experimental results of friction in a mechanical system are reported. Strange properties of the friction force-velocity dependence are shown, where this relationship does not follow the typical assumption of the force proportional to the sign of the relative velocity.

Frictional Behavior of Polystyrene

The Journal of Chemical Physics, 1967
The frictional coefficients of three fractions of polystyrene, each of sharp molecular-weight distribution, have been determined both from diffusion and sedimentation velocity experiments in cyclohexane at 35°C and in cyclohexane at 25°C. The coefficients obtained from the two methods agree within experimental error.

An elastoplastic friction compensator with improved static friction behavior

2016 55th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE), 2016
Mahvash and Okamura's elastoplastic friction compensator is one of successful friction compensators for robotic joints with compliant transmissions. A limitation of the scheme is that, in the static friction state, the compensator continues commanding non-zero output force, which hampers the system's reaction to external forces.

Frictional Behavior of Textile Fabrics

Textile Research Journal, 2000
In this paper, the dynamic response for sliding friction is considered through dynamic models. A new interpretation of the non-uniform sliding phenomenon response is given, based on new topographic details of the fabric surface in front of the leading edge of the sled in movement.

Frictional behavior in superconducting coil

IEEE Transactions on Magnetics, 1985
Experiments were made to obtain information on the role of friction in instability of superconducting coil. We constructed a pin slide type device for friction test which works at cryogenic temperature. The pin slides on the inner most part of the coil wound by Nb-Ti-Zr-Ta conductor.

Friction Behavior in Microsystems

2011
In active microsystems, low lateral propulsive forces act under high contact pressures, thereby requiring a low friction coefficient ??for successful operation. The maximum acceptable friction coefficient is determined by the available driving forces.

A strange behavior of friction

The Physics Teacher, 1999
We investigate the effects of dry, sliding friction between a felt-covered wood block and a wooden table. By measuring the applied force and the acceleration of the block, we experimentally determine the force of kinetic friction and find that it is constant when the applied force is larger than a terminal frictional force Ft=μtmg.

Nanoscopic friction behavior of pharmaceutical materials

International Journal of Pharmaceutics, 2007
The characteristics of various pharmaceutical dosage forms are influenced by surface properties such as the friction behavior. For example, die wall friction is a key issue in developing a solid dosage form. However, the friction properties are not completely understood mainly because of the lack of fundamental measurements.

Frictional behavior of sputtered TiN

Wear, 1987
Abstract In this research, reciprocating sliding experiments were conducted on films of sputtered TiN. The primary emphasis was to evaluate the effect of the applied film thickness on the friction coefficient. Other parameters namely, surface roughness, substrate hardness and applied load were also varied and their effects were studied.
