Natural high-performance materials inspire the pursuit of ordered hard/soft nanocomposite structures at high fractions of reinforcements and with balanced molecular interactions. Herein, we develop a facile, waterborne...

Approaches to Program the Time Domain of Self-Assemblies

December 27, 2015

Laura Heinen, and Andreas Walther

Get the full paper here: Soft Matter, 11, 7857 (2015).

Self-regulating reconfigurable soft matter systems are of great interest for creating adaptive and active material properties. Such complex functionalities emerge from non-linear and interactive behavior in space an...

Biocatalytic Feedback-Driven Temporal Programming of Self-Regulating Non-Equilibrium Peptide Hydrogels

December 25, 2015

Thomas Heuser, Elisabeth Weyandt, and Andreas Walther

Get the full paper here: Angew. Chem. Int. Ed, 54, 13258 (2015).

Switchable self-assemblies respond to external stimuli with a transition between near-equilibrium states. Although being a key to present-day advanced materials, these systems respond rather passively, and...

Polyacid Microgels with Adaptive Hydrophobic Pockets and Ampholytic Character: Synthesis, Solution Properties and Insights into Internal Nanostructure by cryogenic-TEM

December 23, 2015

Rahul Tiwari, Thomas Heuser, Elisabeth Weyandt, Baochun Wang, and Andreas Walther
