Interfacial Water Coordination on Ruthenium Oxide Nanoparticles Confined Within Covalent Organic Framework and Its Effect on Electrochemical Nitrate Reduction

Advanced Science, EarlyView.
We demonstrate how oxygen‐deficient ruthenium oxide (RuOx) nanoparticles confined within covalent organic framework achieve highly efficient nitrate‐to‐ammonia conversion. Strong interaction between RuOx nanoparticles and COF results in modified interfacial hydrogen‐bond water network and adsorption of nitrogenous intermediates.

Interacting Parallel Fluidic Hysterons

Advanced Science, EarlyView.
The parallel coupling of fluidic hysterons is introduced, establishing advanced functionalities in inflatable soft systems. A pressure–volume framework reveals how preset volumes Δv∗${\Delta }v^*$ tune nonlinear interactions between hysterons and actuation sequences without changing architecture. Experiments validate the predictions, opening new routes

Decentralized Dynamic Channel Allocation for MIMO Systems

, 2007
A common scenario in wireless communication systems is one where several systems coexist in the same area and communicate using the same portion of the spectrum, possibly even using different radio interfaces. Herein, we consider non-cooperative spectrum

Logic-Driven Semantic Communication for Resilient Multi-Agent Systems

IEEE Open Journal of the Communications Society
The advent of 6G networks is accelerating autonomy, intelligence, and interconnectedness in large-scale, decentralized multi-agent systems (MAS). While this evolution enables highly adaptive behavior, it also heightens vulnerability to stressors such as ...

Interfacial Control in Cu–MXene Hybrids Enables Selective NOx‐to‐NH3 Electroconversion: A Critical Review

Advanced Science, EarlyView.
Cu‐MXene interfacial catalysts provide a promising platform for electrochemical NOx upcycling to ammonia. The synergy between Cu active sites and conductive, surface‐tunable MXene supports promotes NOx adsorption, intermediate stabilization, and selective NH3 formation while suppressing competing hydrogen evolution, offering a route toward sustainable ...
