Moreover, advancement in subcutaneous drug delivery requires effective tissue mimics such as hydrogels for which similar gaps of poroelastic data exist. Porcine subcutaneous samples and gelatin hydrogels were tested under confined compression at physiological conditions and strain rates of 0.01%/s in 5% ...
1b). Mean orientation angle of the PCL fibers was 8.5° (σ² = 48.5) before compression and 8.2° (σ² = 42.6) after compression (Fig. 1c). The MC microfibrils that formed by a collagen-induced biomimetic mineralization process and uniformly encapsulated within the PCL ...
A hydrogel system that is capable of mitigating energy under hydrostatic compression has been developed by the incorporation of HNPs into PAM hydrogel network. Compare to the neat hydrogel, which has negligible energy mitigation capacity, the LN-hydrogels exhibit much enhanced energy mitigation capacity...
In agarose gels, only the cells in the middle zone of the gel deformed significantly under compression while cells in the other zones underwent deformation that was not statistically significant. These findings indicate that deformation of chondrocytes seeded hydrogels under compression is both ...
Energy-dissipation elastomers relying on their viscoelastic behavior of chain segments in the glass transition region can effectively suppress vibrations and noises in various fields, yet the operating frequency of those elastomers is difficult to control precisely and its range is narrow. Here, we repo...
Xerogel SPH-1 adsorbent water spheres (1441 ± 11μm; sphericity of 0.98; ΔV/V ∼87%; soft gels (Leonard, 1997) with mechanical resistance to compression of 24.7 ± 1.9 MPa) remain intact, while xerogel SPH-2 adsorbent water spheres (∼1732μm; sphericity of 0.98; ΔV/V ∼...
Our objective was to enhance the precision of force measurements and improve sample visibility during compression testing. We compared the performance of our innovative 3D-printed confined compression setup to a conventional setup by performing stress relaxation testing on hydrogels with variab...
Particle inclusions also suppress stiffening in shear deformation; when the particle volume fraction is low, they have little effect on the elasticity of the polymer networks. However, as the particles become more closely packed, the material switches from compression softening to compression stiffening...
