Photo-induced viscoelasticity in cytocompatible hydrogel substrates [PDF]

open access: yesNew Journal of Physics, 2019
Human mesenchymal stem cells (hMSCs) sense and respond to the bulk elastic and viscoelastic properties of their microenvironment, as well as the spatial distribution of these mechanical signals.

Viscoelasticity of ECM and cells—origin, measurement and correlation

open access: yesMechanobiology in Medicine
The extracellular matrix (ECM) and cells are crucial components of natural tissue microenvironments, and they both demonstrate dynamic mechanical properties, particularly viscoelastic behaviors, when exposed to external stress or strain over time.

An approach to nonlinear viscoelasticity via metric gradient flows [PDF]

open access: yes, 2013
We formulate quasistatic nonlinear finite-strain viscoelasticity of rate type as a gradient system. Our focus is on nonlinear dissipation functionals and distances that are related to metrics on weak diffeomorphisms and that ensure time-dependent frame ...

Effect of PMMA polymer on the dynamic viscoelasticity and plasticizer leachability of PEMA-based tissue conditioners [PDF]

open access: yes, 2010
The purpose of this study was to determine the effect of PMMA polymer on dynamic viscoelasticity and plasticizer leachability of PEMA-based tissue conditioners. One PEMA polymer and one PMMA polymer were used in powder form with four formulations.

Bubble dynamics in polymeric foams [PDF]

open access: yes, 2004
The effects of fluid viscoelasticity on the expansion of gas bubbles in polymer foams for both non-reactive and reactive polymers are investigated. Polymer foams are used extensively in consumer products, from car parts to upholstery.

Relative entropy in diffusive relaxation [PDF]

open access: yes, 2012
We establish convergence in the diffusive limit from entropy weak solutions of the equations of compressible gas dynamics with friction to the porous media equation away from vacuum.

Influence of supramolecular forces on the linear viscoelasticity of gluten [PDF]

open access: yes, 2016
Stress relaxation behavior of hydrated gluten networks was investigated by means of rheometry combined with μ-computed tomography (μ-CT) imaging. Stress relaxation behavior was followed over a wide temperature range (0–70 °C).

Membrane viscoelasticity

open access: yesBiophysical Journal, 1976
In this paper, we develop a theory for viscoelastic behavior of large membrane deformations and apply the analysis to the relaxation of projections produced by small micropipette aspiration of red cell discocytes. We show that this relaxation is dominated by the membrane viscosity and that the cytoplasmic and extracellular fluid flow have negligible ...
