Superior Impact‐Resistant Composite Hydrogels Through an Ionic Coupling Strategy
An ionic coupling strategy is developed to simultaneously reinforce networks and interfaces in composite hydrogels. Sodium citrate acts as a single multifunctional ionic coupler to strengthen the poly(vinyl alcohol) matrix via the Hofmeister effect, reinforce the chitosan–sodium alginate nanofiber network via desolvation and electrostatic crosslinking,

This study presents the rational design and synthesis of a highly luminescent polymeric nanocomposite. Initially, highly fluorescent carbon quantum dots (CQDs) are synthesized via a facile hydrothermal method using citric acid and β‐alanine as precursors, followed by rigorous purification through centrifugation and filtration.

Hydrogel‐Based 3D‐Printable Stretchable Pressure Sensor
We present a carbon‐black‐functionalized double‐network granular hydrogel (DNGH) pressure sensor capable of detecting pressures from 200 Pa, equivalent to a light finger touch, up to 500 kPa. The sensor exhibits signal drifts below 3.5% after 800 cycles and response times around 80 ms. Leveraging this broad sensing range, we 3D print this material into
