Advanced Functional Materials, EarlyView.Guided by the golden ratio, a class of aperiodic architected metamaterials is introduced to address the intrinsic trade‐off between strength and toughness. By unifying local geometric heterogeneity with global order, the golden‐ratio‐guided aperiodic architecture promotes spatial delocalization of damage tolerence regions, leading to more tortuous ...

Crack‐Growing Interlayer Design for Deep Crack Propagation and Ultrahigh Sensitivity Strain Sensing
Advanced Functional Materials, EarlyView.A crack‐growing semi‐cured polyimide interlayer enabling deep cracks for ultrahigh sensitivity in low‐strain regimes is presented. The sensor achieves a gauge factor of 100 000 at 2% strain and detects subtle deformations such as nasal breathing, highlighting potential for minimally obstructive biomedical and micromechanical sensing applications ...

Charge‐Induced Morphing Gels for Bioinspired Actuation
Advanced Functional Materials, EarlyView.This study introduces a novel electroactive actuation mechanism that enables the gel material to generate substantial and reversible shape‐changing while preserving topological and isochoric (volumetric) equivalence. The resultant morphing behaviors can mimic the movements of muscle‐driven organelles in nature, including cilia‐like beating and ...

Freeze-dried embedded specimens for biological microanalysis. [PDF]
Scanning electron microscopy, 1986 The main problems associated with freeze-drying of biological material for electron microscopy concern the freeze-drying temperatures and times necessary to minimize artifacts. Due to the many parameters involved these problems have to be resolved experimentally.

Precursor Mineral Phases of Forming Mollusk Shell Nacre: A Study of Hydrated Samples
Advanced Functional Materials, EarlyView.Mineral, organic phase, and water are the essential components in mollusk shell nacre formation. Their interplay is not well understood, because the hydrated material is difficult to observe at high resolution, under close to native conditions. Forming nacre is studied using environmental and cryo‐electron microscopy and hydrated ACC phases, together ...
