Magnetic non-contact friction from domain wall dynamics actuated by oscillatory mechanical motion [PDF]

open access: yes, 2019
Magnetic friction is a form of non-contact friction arising from the dissipation of energy in a magnet due to spin reorientation in a magnetic field.

Experimental Verification of New Function Theories of Particles (1)-Experimental Verification of New Kinetic Energy Theorem of Rigid Body Fixed Axis Rotation

open access: yesMATEC Web of Conferences, 2017
Sliding friction torque does dissipative work on the force-bearer, transforming the kinetic energy of the bearer into internal energy and others of the bearer.

Determination of soil shear properties on a soil to concrete interface using a direct shear box apparatus

open access: yesInternational Journal of Geo-Engineering, 2017
Direct shear experiments were carried out both to investigate the interaction between a predominantly cohesion less soil and in-situ concrete and the validation of the tangent of two-third of the angle of internal friction angle normally assumed in ...

Rheophysics of dense granular materials : Discrete simulation of plane shear flows [PDF]

open access: yes, 2005
We study the steady plane shear flow of a dense assembly of frictional, inelastic disks using discrete simulation and prescribing the pressure and the shear rate.

Amplitude Dependent Internal Friction in a Mg-Al-Zn Alloy Studied after Thermal and Mechanical Treatment

open access: yesMetals, 2017
The amplitude-dependent internal friction of continuously-cast and rolled AZ31 magnesium alloy was measured in this study. Samples were annealed and quenched step by step; immediately after the treatment, the amplitude dependence of the logarithmic ...

Crack Growth in Hydrous Soda-Lime Silicate Glass

open access: yesFrontiers in Materials, 2020
Stable crack growth was measured for nominal dry and water-bearing (6 wt%) soda-lime silicate glasses in double cantilever beam geometry and combined with DMA studies on the effects of dissolved water on internal friction and glass transition ...

Looping dynamics of flexible chain with internal friction at different degree of compactness

open access: yes, 2015
Recently single molecule experiments have shown the importance of internal friction in biopolymer dynamics. Such studies also suggested that the internal friction although independent of solvent viscosity has strong dependence on denaturant concentration.

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

open access: yesMolecular Oncology, EarlyView.
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Monitor for physical property changes in solid propellants [PDF]

open access: yes, 1973
Specially designed sensor is attached to or imbedded in propellant. When sensor is driven into vibration, it moves with a phase lag directly proportional to internal friction or loss coefficent.

Internal Friction and Vulnerability of Mixed Alkali Glasses

open access: yes, 2005
Based on a hopping model we show how the mixed alkali effect in glasses can be understood if only a small fraction c_V ofthe available sites for the mobile ions is vacant. In particular, we reproduce the peculiar behavior of the internal friction and the
