Viscoelasticity of Liposomal Dispersions

open access: yesNanomaterials, 2023
Janus-faced viscoelastic gelling agents—possessing both elastic and viscous characteristics—provide materials with unique features including strengthening ability under stress and a liquid-like character with lower viscosities under relaxed conditions ...

Active Viscoelasticity of Sarcomeres [PDF]

open access: yesFrontiers in Robotics and AI, 2018
The perturbation response of muscle is important for the versatile, stable and agile control capabilities of animals. Muscle resists being stretched by developing forces in the passive tissues and in the active crossbridges.

Viscoelastic Snapping Metamaterials [PDF]

open access: yesJournal of Applied Mechanics, 2019
Abstract Mechanical metamaterials are artificial composites with tunable advanced mechanical properties. Particularly, interesting types of mechanical metamaterials are flexible metamaterials, which harness internal rotations and instabilities to exhibit programable deformations.

Passive odd viscoelasticity

open access: yesPhysical Review E, 2022
Active chiral viscoelastic materials exhibit elastic responses perpendicular to the applied stresses, referred to as odd elasticity. We use a covariant formulation of viscoelasticity combined with an entropy production analysis to show that odd elasticity is not only present in active systems but also in broad classes of passive chiral viscoelastic ...

Viscoelastic surface electrode arrays to interface with viscoelastic tissues

open access: yesNature Nanotechnology, 2021
Living tissues are non-linearly elastic materials that exhibit viscoelasticity and plasticity. Man-made, implantable bioelectronic arrays mainly rely on rigid or elastic encapsulation materials and stiff films of ductile metals that can be manipulated with microscopic precision to offer reliable electrical properties.

Viscoelastic hydrodynamics and holography [PDF]

open access: yesJournal of High Energy Physics, 2020
Abstract We formulate the theory of nonlinear viscoelastic hydrodynamics of anisotropic crystals in terms of dynamical Goldstone scalars of spontaneously broken translational symmetries, under the assumption of homogeneous lattices and absence of plastic deformations. We reformulate classical elasticity effective field theory using

Viscoelastic levitation

open access: yesJournal of Fluid Mechanics, 2022
The effects of viscoelasticity have been shown to manifest themselves via symmetry breaking. In this investigation, we show a novel phenomenon that arises from this idea. We observe that when a dense sphere is rotated near a wall (the rotation being aligned with the wall-normal direction and gravity), it levitates to a fixed distance away from the wall.

Decoupling between Translational Diffusion and Viscoelasticity in Transient Networks with Controlled Network Connectivity

open access: yesGels, 2022
The mobility of sustained molecules is influenced by viscoelasticity, which is strongly correlated with the diffusional property in polymeric liquid. However, the study of transient networks formed by a reversible crosslink, which is the viscoelastic ...

Photoacoustic viscoelasticity imaging dedicated to mechanical characterization of biological tissues [PDF]

open access: yesJournal of Innovative Optical Health Sciences, 2017
Since changes in mechanical properties of biological tissues are often closely related to pathology, the viscoelastic properties are important physical parameters for medical diagnosis.

Viscoelasticity, Like Forces, Plays a Role in Mechanotransduction

open access: yesFrontiers in Cell and Developmental Biology, 2022
Viscoelasticity and its alteration in time and space has turned out to act as a key element in fundamental biological processes in living systems, such as morphogenesis and motility.
