Deterministic transfer of two-dimensional materials by all-dry viscoelastic stamping [PDF]
, 2013 The deterministic transfer of two-dimensional crystals constitutes a crucial step towards the fabrication of heterostructures based on the artificial stacking of two-dimensional materials. Moreover, controlling the positioning of two-dimensional crystals

Viscoelastic microfluidics: progress and challenges
Microsystems & Nanoengineering, 2020 The manipulation of cells and particles suspended in viscoelastic fluids in microchannels has drawn increasing attention, in part due to the ability for single-stream three-dimensional focusing in simple channel geometries.

Biophysical 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 ...

Chemical control of the viscoelastic properties of vinylogous urethane vitrimers
Nature Communications, 2017 Vinylogous urethane based vitrimers are polymer networks that have the intrinsic property to undergo network rearrangements, stress relaxation and viscoelastic flow, mediated by rapid addition/elimination reactions of free chain end amines.

Measuring nanoscale viscoelastic parameters of cells directly from AFM force-displacement curves
Scientific Reports, 2017 Force-displacement (F-Z) curves are the most commonly used Atomic Force Microscopy (AFM) mode to measure the local, nanoscale elastic properties of soft materials like living cells.
