The Effect of Hydrophilic Headgroup Chemistry on Peptoid‐Directed Mineralization of CaCO3
Advanced Functional Materials, EarlyView.Amphiphilic peptoids alter the pathway and outcome of calcium carbonate crystallization, which progresses through amorphous calcium carbonate (ACC) to vaterite to calcite rhombs in the absence of peptoids. In contrast, amine‐terminated peptoids produce vaterite disks and carboxyl‐terminated peptoids produce calcite mesocrystals.

Asymmetry in Skipping Enhances Viability Against Control Input Noise
Advanced Robotics Research, EarlyView.Quadruped animals use asymmetric galloping gaits at high speeds, yet the functional role of this asymmetry remains unclear. This study shows that left–right asymmetry in touchdown angles enhances robustness to control noise. Using a simple two‐legged locomotion model and viability theory, it demonstrates that asymmetric skipping substantially enlarges ...
