Summary: Conductive yarns have shown potential as a replacement for metallic wires in e-Textile devices. However, the parasitic capacitance induced by their micro-structure is not fully understood. This study proposes a model to analyze and quantify the parasitic elements of conductive yarns in air-core helical inductors. The results show that the parasitic capacitance of commercial conductive yarns ranges from 1 fF/cm to 3 fF/cm depending on the yarn's microstructure, providing valuable insights for the design and use of conductive yarns in e-textile devices.

Summary: A flexible on-skin electronic device with multifunctional sensing properties and self-driven anti-infection therapy was successfully developed using cellulose nanocrystals/iron(III) ion/polyvinyl alcohol (CNC/Fe3+/PVA) composite. The composite films exhibited robust mechanical performance, outstanding conductivity, and distinguished breathability due to the multiple interactions of weak hydrogen bonds and Fe3+ chelation, and synergistic effects among CNC, PANI, and PVA. The device could actively monitor real-time physical and infection related signals and act as a self-driven therapist to eliminate bacteria by releasing Fe3+ driven by high temperature caused by infection at wound sites.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
