Amorphous CaCO3: Influence of the Formation Time on Its Degree of Hydration and Stability

Francesco Stellacci, Esther Amstad, Huachuan Du, Mathias Steinacher, Anna Murello

Calcium carbonate (CaCO3) is one of the most abundant biominerals that is prevalent in rocks and often used as a structural material in marine animals. Many of these natural CaCO3-based materials display excellent mechanical properties that are difficult t ...

Additives: Their Influence on the Humidity- and Pressure-Induced Crystallization of Amorphous CaCO3

Esther Amstad, Huachuan Du, Mathias Steinacher

Nature possesses a unique control over the formation of CaCO3 crystals that imparts fascinating mechanical properties to many CaCO3-based biomaterials. This high level of control is, at least in part, achieved through the use of certain soluble additives t ...

Production of Additive‐Free Amorphous Nanoparticles with a SAW‐Based Microfluidic Spray‐Dryer

Duncan Christophe Emmanuel Gilbert, Esther Amstad, Huachuan Du, Mathias Steinacher

Spray‐drying is a widely employed, cost‐effective process to formulate solutions into solid particles of controlled sizes and compositions. In addition, this process can also offer control over the structure of spray‐dried particles: if the solvent is evap ...

Reinforcing hydrogels with in situ formed amorphous CaCO3

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

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 ...

Monodisperse Selectively Permeable Hydrogel Capsules Made from Single Emulsion Drops

Esther Amstad, Alexandre Louis André Persat, Huachuan Du, Mathias Steinacher, Alice Cont

Capsules are often used to protect chemical and biological entities from the environment, to control the timing and location of their release, or to facilitate the collection of waste. Their performance depends on the thickness and composition of their she ...

Water: How does it influence the CaCO3 formation?

Esther Amstad, Huachuan Du

Nature produces biomineral‐based materials with a fascinating set of properties using only a limited number of elements. This set of properties is obtained by closely controlling the structure and local composition of the biominerals. We are far from obtai ...

Fabrication of Hexagonal-Prismatic Granular Hydrogel Sheets

Esther Amstad, Huachuan Du, Mathias Steinacher, Alice Cont

Natural soft materials are often composed of proteins that self-assemble into well-defined structures and display mechanical properties that cannot be matched by manmade materials. These materials are frequently mimicked with hydrogels whose mechanical pro ...
