Influence of Chain Extender on The Thermal, Rheological, and Supercritical Foaming Behavior of Polyamide‐12

open access: yesMacromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Chain extender concentration strongly influence the batch foaming behavior of PA 12 under supercritical CO2. Increasing CE content improves melt stability, raises viscosity and broadens the foaming window, enabling fine, uniform cellular structures. The optimal 0.5 wt.% CE yields the highest nucleation density and lowest foam density, about 0.06–0.09 g/

InSe‐Enabled Wearable Triboelectric Nanogenerator for Biomechanical Energy Harvesting and Motion Sensing

open access: yesChemistryOpen, Volume 15, Issue 8, August 2026.
An InSe‐enabled wearable triboelectric nanogenerator is developed using a PTFE/InSe friction pair for biomechanical energy harvesting and self‐powered motion sensing. The compacted InSe layer promotes interfacial contact and charge generation, enabling high electrical output, capacitor charging, durable operation, and wearable detection of finger ...
