Li/Al‐LDH Reinforced Polyacrylamide/Xanthan Gum Semi‐Interpenetrating Network Nano‐Conductive Hydrogels for Stress Sensing and Wearable Device Applications

Advanced Science, EarlyView.
PXL hydrogel is prepared by in situ polymerization of acrylamide (AM) between Li/Al‐LDH nanosheets and forming a semi‐interpenetrating network structure with xanthan gum (XG). The in situ polymerization of AM ensures the uniform distribution of Li/Al‐LDH within the hydrogel network.

Cu3SbSe3‐Alloying‐Induced High Thermoelectric Performance and Mechanical Robustness in Bi2Te3‐Based Thermoelectric Materials

Advanced Science, EarlyView.
Combining microstructural engineering with Cu3SbSe3 alloying significantly improves the performance of Bi2Te3‑based thermoelectric materials, yielding a high zT of ≈1.45 (average zT ≈1.3 over 303–503 K), excellent mechanical robustness (Vickers hardness of 96 Hv and compressive strength of 187 MPa), and an impressive conversion efficiency of ≈6.9% at a
