Dependence of boundary lubrication on the misfit angle between the sliding surfaces

, 2010
Using molecular dynamics based on Langevin equations with a coordinate- and velocity-dependent damping coefficient, we study the frictional properties of a thin layer of "soft" lubricant (where the interaction within the lubricant is weaker than the ...

Evaluation of coefficient of friction in similar conditions to ejection of molding parts [PDF]

, 2014
The injection molding is the technique most used for processing polymers. Nowadays, due to economic demands the ejection of the parts occur as soon as possible to lead to a short cycle times.

Effects of Microscale Texture on the Tribological Behavior of Paper-Based Friction Materials for a Wet Clutch

Tribology Online, 2015
Paper-based friction materials used for wet clutches in automatic transmissions require various tribological functions such as a high and stable friction coefficient, good μ-V (friction coefficient-sliding velocity) characteristics, heat resistance ...

The Role of Solid Friction in the Sedimentation of Strongly Attractive Colloidal Gels

, 2006
We study experimentally and theoretically the sedimentation of gels made of strongly aggregated colloidal particles, focussing on the long time behavior, when mechanical equilibrium is asymptotically reached.

Frictional Effects in Biomimetic Scales Engagement

, 2015
Scales engagement can contribute significantly to nonlinear bending behavior of elastic substrates with rigid biomimetic scales. In this letter, we investigate the role of friction in modulating the nonlinearity that arises due to self-contact of scales ...

Surface property effects of compounding a nanoclay masterbatch in PP injection moulding [PDF]

, 2010
Indicado para o prémio de melhor artigo mais inovador.The interest on the use of nanofillers in injection mouldings has been going on for more than a decade but a real breakthrough has not been achieved yet, especially in that mechanical properties are ...

Rheological aging and rejuvenation in solid friction contacts

, 2002
We study the low-velocity (0.1--100 $\mu$m.s$^{-1}$) frictional properties of interfaces between a rough glassy polymers and smooth silanized glass, a configuration which gives direct access to the rheology of the adhesive joints in which shear localizes.

Calibration and Analysis of Seeding Parameters of Soaked Cyperus esculentus L. Seeds

Applied Sciences
The seeds of Cyperus esculentus L. exhibit an uneven surface and irregular shape, which adversely affect precision seeding. Pre-sowing seed soaking treatment not only improves seeding performance, but also enhances the germination capability of C ...
