Electrostatically Reinforced Double Network Granular Hydrogels

Esther Amstad, John Martin Kolinski, Chenzhuo Li, Tianyu Yuan

Rapid advances in biomedical applications and soft robotics demand load-bearing soft materials that can be processed into complex 3D shapes. Direct ink writing (DIW) enables the fabrication of customizable shapes with locally varying compositions. Hydrogel ...

Additive Manufacturing of Porous Biominerals

Esther Amstad, Matteo Hirsch, Gaia De Angelis, Ran Zhao, Tianyu Yuan

Nature fabricates hard functional materials from soft organic scaffolds that are mineralized. To enable an energy-efficient locomotion of these creatures while maintaining their structural stability, nature often renders parts of these minerals porous. Unf ...

Influence of the Degree of Swelling on the Stiffness and Toughness of Microgel-Reinforced Hydrogels

Esther Amstad, John Martin Kolinski, Tianyu Yuan, Michael David Kessler

The stiffness and toughness of conventional hydrogels decrease with increasing degree of swelling. This behavior makes the stiffness-toughness compromise inherent to hydrogels even more limiting for fully swollen ones, especially for load-bearing applicati ...

Reinforcing hydrogels with in situ formed amorphous CaCO3

Esther Amstad, Matteo Hirsch, Ran Zhao, Tianyu Yuan, Huachuan Du, Michael David Kessler

Hydrogels are often employed for tissue engineering and moistening applications. However, they are rarely used for load-bearing purposes because of their limited stiffness and the stiffness-toughness compromise inherent to them. By contrast, nature uses hy ...
