Compression and reswelling of microgel particles after an osmotic shock
Jelle F. Sleeboom, Panayiotis Voudouris, Melle T. J. J. M. Punter +4
We use dedicated microfluidic devices to expose soft hydrogel particles to a rapid change in the externally applied osmotic pressure and observe a non-monotonic response: After an…
Mechanics from Calorimetry: A New Probe of Elasticity for Responsive Hydrogels
Frank J. Aangenendt, Johan Mattsson, Wouter G. Ellenbroek +1
Temperature-sensitive hydrogels based on polymers such as poly(N-isopropylacrylamide) (PNIPAM) undergo a volume phase transition in response to changes in temperature. During this…
Diffusing-Wave Spectroscopy in a Standard Dynamic Light Scattering Setup
Zahra Fahimi, Frank Aangenendt, Panayiotis Voudouris +2
Diffusing-Wave Spectroscopy (DWS) treats the transport of photons through turbid samples as a diffusion process, thereby making it possible to extract the dynamics of scatterers fr…
Capillary micromechanics: Measuring the elasticity of microscopic soft objects
Hans M. Wyss, Thomas Franke, Elisa Mele +1
We present a simple method for accessing the elastic properties of microscopic deformable particles. This method is based on measuring the pressure-induced deformation of soft part…
Strain-Rate Frequency Superposition (SRFS) - A rheological probe of structural relaxation in soft materials
Hans M. Wyss, Kunimasa Miyazaki, Johan Mattsson +3
The rheological properties of soft materials often exhibit surprisingly universal linear and non-linear features. Here we show that these properties can be unified by considering t…
Nonlinear viscoelasticity of metastable complex fluids
Kunimasa Miyazaki, Hans M. Wyss, D. A. Weitz +1
Many metastable complex fluids such as colloidal glasses and gels show distinct nonlinear viscoelasticity with increasing oscillatory-strain amplitude; the storage modulus decrease…
