Advanced Materials, EarlyView.A universal weakly‐solvated electrolyte design principle is established for phosphorus‐based anodes through systematic evaluation. Based on this criterion, the fluorinated solvent of FEC emerges as the optimal co‐solvent, effectively suppressing the dissolution of lithium polyphosphides while enhancing desolvation/charge‐transfer kinetics and ...

P3HT‐Based Electroactive Films for In Vitro Neuronal Cell Interfacing
Advanced Materials Interfaces, EarlyView.Reducing the mechanical mismatch between bioelectronic devices and tissue is crucial for enhancing the characteristics of biointerfaces that better mimic the biological tissues. This work investigates the physico‐chemical properties of tunable nanostructured surfaces obtained from a blend of P3HT and MWCNT electroactive polymer.

Wafer‐Scale Synthesis of Topological Insulator Sb2Te3 Thin Films
Advanced Materials Interfaces, EarlyView.This work demonstrates how the topologically protected conduction in Sb2Te3 thin films can be extended from few‐mm2 samples’ area up to larger areas of several cm2 Si(111) wafers. The reported findings represent a breakthrough for the future technology scale‐up of topological insulators for applications such as spintronics, thermoelectrics, and quantum

A Sharded Blockchain-Based Secure Federated Learning Framework for LEO Satellite Networks [PDF]
arXivLow Earth Orbit (LEO) satellite networks are increasingly essential for space-based artificial intelligence (AI) applications. However, as commercial use expands, LEO satellite networks face heightened cyberattack risks, especially through satellite-to-satellite communication links, which are more vulnerable than ground-based connections. As the number
