Tough Injectable Hydrogels Enabled by Integrating Rigid Homogeneous Framework With Flexible Chains

Advanced Functional Materials, EarlyView.
Tough injectable hydrogels are constructed by integrating a rigid, homogeneous hyaluronic acid framework with flexible long‐chain connectors. This framework–flexible structure simultaneously enhances network uniformity and promotes effective energy dissipation by enlarging plastic deformation zones under compression.

Design Strategies and Emerging Applications of High‐Performance Flexible Piezoresistive Pressure Sensors

Advanced Functional Materials, EarlyView.
Flexible piezoresistive pressure sensors underpin wearable and soft electronics. This review links sensing physics, including contact resistance modulation, quantum tunneling and percolation, to unified materials/structure design. We highlight composite and graded architectures, interfacial/porous engineering, and microstructured 3D conductive networks

Group association and vocal behaviour during foraging trips in Gentoo penguins

Scientific Reports, 2017
In contrast to their terrestrial call, the offshore call of penguins during their foraging trips has been poorly studied due to the inaccessibility of the foraging site—the open ocean—to researchers.

Polymer Interface Enables Reversible Quasi‐Solid Sulfur Conversion in Sodium‐Sulfur Batteries

Advanced Functional Materials, EarlyView.
The polymer interface enables a stable quasi‐solid sulfur conversion pathway in room‐temperature Na─S batteries. The coating regulates Na+ transport, stabilizes the cathode–electrolyte interphase, and accommodates mechanical stress, suppressing electrolyte decomposition and sulfur migration, thereby improving reaction uniformity, reducing polarization,

A proposal for epithelial dominance in extremely high fundamental frequency vocalizations

The Journal of the Acoustical Society of America
In this hypothesis article, we explore the upper limit of the fundamental frequency in vocalization. Most mammalian vocalizations are produced by airflow-induced, self-sustained vibration of vocal folds, with fundamental frequency being determined by multiple tissue layers in the folds, including muscle, ligament, and epithelial tissues.
