Microrheology and microstructure of poly(vinyl alcohol)-based physical gels
We study the microrheology and microstructure of physically cross-linked poly(vinyl alcohol) (PVA) gels using atomic force microscopy, dynamic light scattering and particle tracking. We compare the microscopic rheological properties with the bulk properties measured using conventional shear …

Time-resolved linear and non-linear rheology of thixotropic and aging complex fluids: Application to particulate and biopolymeric physical gels
… ubiquitously observed in materials such as hydrogels, food products and drilling fluids. These materials are in general known as mutating materials and the build-up or breakdown of microstructure is commonly both time– and shear-rate (or shear-stress)–dependent resulting in a range of complex …

Rheometric measurement of hydrogel toughness
As soft physical gels become more popular due to their biological applications, there is increased interest in measuring mechanical properties such as toughness. However, traditional tensile testing methods do not work for such materials due to the intrinsic softness of the material. We present a …

Uncoupled Stability of Haptic Simulation of Viscoelastic Virtual Environments
… environments, the stable implementable range of physical deformable objects implemented as a VE is also found. Physical gels with known Young’s Moduli are experimentally tested to determine their point of contact apparent stiffness and damping for varying penetration. These parameters are …

Synthesis, nanostructure, and mechanics of thermoresponsively tough biomaterials from artificial polypeptides
Artificial protein hydrogels have attracted interest as injectable fillers and scaffolds for tissue engineering and regeneration, but the same features that enable minimally-invasive implantation of these biomaterials typically make them susceptible to mechanical degradation in the tissue …
