Understanding the friction mechanisms between the human finger and flat contacting surfaces in moist conditions

open access: yes, 2010
Human hands sweat in different circumstances and the presence of sweat can alter the friction between the hand and contacting surface. It is, therefore, important to understand how hand moisture varies between people, during different activities and the ...

Existence of long‐time solutions to dynamic problems of viscoelasticity with rate‐and‐state friction [PDF]

open access: yes, 2019
We establish existence of global solutions to a dynamic problem of bilateral contact between a rigid surface and a viscoelastic body, subject to rate‐and‐state friction.

Research progress in inertia friction welding of nickel-based superalloys

open access: yesCailiao gongcheng
Nickel-based superalloys are widely used in high-temperature turbine components of aviation engines, and inertia friction welding (IFW) is widely used for the connection of nickel-based superalloy disc and shaft due to its solid-phase bonding property ...

Environmental effects on the wear characteristics of phenolic resin composite (Confirmation of water vapor effects and proposal of tribo-degraded gas effects)

open access: yesNihon Kikai Gakkai ronbunshu, 2016
For the purpose of clarifying the water vapor effect on brake pad wear, two experiments were performed. In the first set of experiments, wear tests were conducted using four pads under three relative humidity conditions (0.8%RH, 35%RH and 65%RH).

On the association between microhardness, corrosion resistance and microstructure of probeless friction stir spot welded Al–Li joint

open access: yesJournal of Materials Research and Technology, 2021
The precipitation behavior and development of grain structure have been investigated to reveal their association with the microhardness and corrosion resistance of probeless friction stir spot welded (P-FSSW) joint of an Al–Li alloy.

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

open access: yesFEBS 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 ...

Voltage-Induced Friction with Application to Electrovibration

open access: yesLubricants, 2019
Due to the growing interest in robotic and haptic applications, voltage-induced friction has rapidly gained in importance in recent years. However, despite extensive experimental investigations, the underlying principles are still not sufficiently ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Investigating the Feasibility of Integrating Pavement Friction and Texture Depth Data in Modeling for INDOT PMS [PDF]

open access: yes, 2012
Under INDOT’s current friction testing program, the friction is measured annually on interstates but only once every three years on non-interstate roadways.
