Internal Friction and Dynamic Modulus in Ultra-High Temperature Ru-Nb Functional Intermetallics / Tarcie Wewnętrzne I Moduł Dynamiczny W Bardzo Wysoko Temperaturowych Funkcjonalnych Związkach Międzymetalicznych Z Układu Ru-Nb

open access: yesArchives of Metallurgy and Materials, 2015
In the present work we have studied the high-temperature shape memory alloys based on the Ru-Nb system by using two mechanical spectrometers working in temperature ranges from 200 to 1450ºC and -150 to 900ºC.

Viscoelastic behaviour of basaltic lavas. [PDF]

open access: yes, 2004
The rheological properties of basaltic lavas from Etna, Hawai′i and Vesuvius have been investigated at temperatures between 500 and 1150°C using a small-strain oscillatory shear. The viscoelastic response of the lavas to small, forced, sinusoidal torques

The Internal Friction of Proteins [PDF]

open access: yesBiophysical Journal, 2014
The rates of protein conformational changes are usually not only limited by external but also internal friction, however, the origin and significance of this latter phenomenon is poorly understood. It is often found experimentally that a linear fit to the reciprocal of the reaction rate as a function of the viscosity of the external medium has a non ...

The role of memory-dependent friction and solvent viscosity in isomerization kinetics in viscogenic media

open access: yesNature Communications
Molecular isomerization kinetics in liquid solvent depends on a complex interplay between the solvent friction acting on the molecule, internal dissipation effects (also known as internal friction), the viscosity of the solvent, and the dihedral free ...

Effect of Hydrogen on the Elastic and Anelastic Properties of the R Phase in Ti50Ni46.1Fe3.9 Alloy

open access: yesMetals, 2017
The linear and non-linear internal friction, effective Young’s modulus, and amplitude-dependent modulus defect of a Ti50Ni46.1Fe3.9 alloy have been studied after different heat treatments, affecting hydrogen content, at temperatures of 13–300 K, and ...

The Influence of Internal Friction on Dilute Polymer Solution Dynamics

open access: yes, 2021
The time rate of spatial reorganisation in polymer molecules is modulated both by solvent friction, and solvent-viscosity-independent intramolecular interactions, collectively termed as ``internal friction''.
