Measuring viscoelasticity of soft biological samples using atomic force microscopy.
Soft Matter, 2019Mechanical properties play important roles at different scales in biology. At the level of a single cell, the mechanical properties mediate mechanosensing and mechanotransduction, while at the tissue and organ levels, changes in mechanical properties are

Shear viscoelasticity of suspensions of biological cells with viscoelastic membrane
Biorheology, 1984To discuss the relaxation phenomena of biological cell suspensions, we have calculated the complex intrinsic viscosity of the dispersion of spherical cells with a viscoelastic membrane as a function of the frequency taking account of interfacial tension at both the interfaces of the membrane.

Charge-Density-Dominated Phase Behavior and Viscoelasticity of Polyelectrolyte Complex Coacervates
Macromolecules, 2019The composition dependence of the phase behavior and viscoelasticity of polyelectrolyte complex coacervates was investigated in a series of model acrylamide copolymers with varying charge density a...

Curing and viscoelasticity of vitrimers
Soft Matter, 2017We present an experimental investigation of the curing kinetics and viscoelasticity for a number of "vitrimers" recently developed by Leibler and coworkers.1-3 Vitrimers are covalently crosslinked networks that can relax stress at elevated temperatures due to thermoreversible bond-exchange reactions.

Analysis of Linear Viscoelasticity of a Crosslinking Polymer at the Gel Point
, 1986We suggest a very simple memory integral constitutive equation for the stress in crosslinking polymers at their transition from liquid to solid state (gel point).

Experientia, 1970
Untersuchungen mit dem Weissenberg-Rheogoniometer zeigen, dass Speichel viskoelastisch ist und dass dessen dynamische Viskositat sich uber einen Frequenzbereich von 2.5×10−3 bis 10 Hz und von 400 bis 0.1 Poise bewegt.

Viscoelastic micropolar continuum and viscoelastic waves
Czechoslovak Journal of Physics, 1976Generalized Kelvin model is applied to isotropic viscoelastic micropolar continuum. Constitutive equations in integral and differential form, generalized Lame equations, and wave equations for displacement and microrotation are derived for this model. For damped viscoelastic waves, which are realized in the continuum under examination, the wave vectors

Dynamics of a viscoelastic cylinder on a viscoelastic half-space
Acta Mechanica, 2020The deceleration of a viscoelastic cylinder rolling with slipping on a viscoelastic half-space of the same material without driving forces and torques is studied. The interaction of the cylinder and the half-space is described from the solution of the 2D quasistatic contact problem of viscoelasticity (Goryacheva in J Appl Math Mech 37(5):877–885, 1973,

We study wall and center migration of viscoelastic droplets in a Poiseuille flow of viscoelastic medium (PVP) at low Reynolds numbers (Re ≪ 1) and propose the existence of a new lift force whose origin lies in the viscoelasticity of the droplet phase.

Dilational Viscoelasticity of Proteins Solutions in Dynamic Conditions.
Langmuir, 2018Drop profile analysis tensiometry used in the oscillating drop mode provides the dilational viscoelasticity of adsorption layers at liquid interfaces. Applied during the progress of adsorption the dynamic surface rheology can be monitored.
