Stochastic models for solution dynamics: The friction and diffusion coefficients [PDF]
The Journal of Chemical Physics, 1988 Molecular dynamics simulations are reported for a solute immersed in a monatomic solvent; systems modeled represent monatomic and diatomic solute species (whose atoms are larger and heavier than the solvent), with varying force constant and bond length for the diatomic.

Establishment and Numerical Analysis of Rolling Force Model Based on Dynamic Roll Gap
Applied Sciences, 2023 Applying mathematical models and numerical methods is crucial for describing and simulating the metal cold-rolling process, wherein the accurate prediction of rolling force is an effective way to improve the quality of rolled sheets. This paper considers

Speed and Atmosphere Influences on Nanotribological Properties of NbSe2 [PDF]
, 2009 Nanotribological properties of NbSe2 are studied using an atomic friction force microscope. The friction force is measured as a function of normal load and scan speeds ranging from 10 nm s−1 to 40 μm s−1 under two atmospheres (air and argon).

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Proposal of the road surface friction coefficient real-time estimation method
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2018 For Autonomous Driving (AD) system or vehicle behavior control, it is important to know the friction coefficient of the road surface accurately. It is because the lateral and the longitudinal force characteristics of the tire depend on the road surface ...

Fluctuating-friction molecular motors [PDF]
, 2001 We show that the correlated stochastic fluctuation of the friction coefficient can give rise to long-range directional motion of a particle undergoing Brownian random walk in a constant periodic energy potential landscape.

Predictive multiscale computational model of shoe-floor coefficient of friction
Journal of Biomechanics, 2018 Understanding the frictional interactions between the shoe and floor during walking is critical to prevention of slips and falls, particularly when contaminants are present. A multiscale finite element model of shoe-floor-contaminant friction was developed that takes into account the surface and material characteristics of the shoe and flooring in ...
