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 ...

A microscopic 2D lattice model of dimer granular compaction with friction

, 2002
We study by Monte Carlo simulation the compaction dynamics of hard dimers in 2D under the action of gravity, subjected to vertical and horizontal shaking, considering also the case in which a friction force acts for horizontal displacements of the dimers.

Comparative Braking Performance Evaluation of a Commercial and Non-asbestos, Cu-free, Carbonized Friction Composites

Medžiagotyra, 2021
Carbonization treatment contributes to improvement of tribological properties of friction composites. Pure Non-asbestos organic (NAO) friction raw materials were selected, friction composite specimens had been made using a new mixing process and ...

Coarse-grained model for spring friction study of micron-scale iron by smoothed particle hydrodynamics

, 2018
The paper constructs a coarse-grained model to investigate dry sliding friction of the body-centered-cubic Fe micron-scale system by smoothed particle hydrodynamics simulations and examines influences of the spring force on the characters of friction ...

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.

Running-In Behavior and Failure Mechanism Between AgCuNi Alloy and Au-Electroplated Layer

Sensors
To avoid wear and tear of the slip ring due to electrical corrosion, the slip ring needs to undergo the running-in process under atmospheric conditions without current after assembly.

Friction hysteretic behavior of supported atomically thin nanofilms

npj 2D Materials and Applications, 2023
Hysteretic friction behavior has been observed on varied 2D nanofilms. However, no unanimous conclusion has yet been drawn on to the exact mechanism or relative contribution of each mechanism to the observed behavior.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...
