Biocompatible but Antibacterial Mechanism of Graphene Oxide for Sustainable Antibiotics

open access: yesAdvanced Functional Materials, EarlyView.
Graphene oxide (GO) exhibits selective antibacterial activity through specific interactions between its oxygen functional groups and bacterial membrane phospholipid POPG, causing membrane destabilization while maintaining biocompatibility. Model membrane studies and infected wound models in mice and pigs demonstrate effective bacterial suppression and ...

Magnetothermal‐Triggered Response and Self‐Healing of Recyclable and Reprocessable Nanocomposites for Actuation Systems

open access: yesAdvanced Functional Materials, EarlyView.
Developing recyclable materials for magnetic robotics that combine rapid response and self‐healing properties is challenging. Hence, this study focuses on the integration of magnetothermal nanoparticles into a dynamic sorbitol‐based vitrimer, a recyclable composite capable of remote actuation and self‐healing by magnetic heating.

Fast Track to the Overdoped Regime of Superconducting YBa2Cu3O7‐δ Thin Films via Electrochemical Oxidation

open access: yesAdvanced Functional Materials, EarlyView.
Overdoping high temperature superconductors, such as YBa2Cu3O7‐δ (YBCO), is expected to maxime the critical current density by optimising the condensation energy for a given defect landscape, providing new thrust for the development of fusion enabling coated conductors. Here, precise oxygen control is achieved via an electrochemical method allowing for

Fast Fault-Tolerant Grid Frequency Measurement

open access: yes2025 IEEE Power & Energy Society General Meeting (PESGM)
As power systems adopt greater levels of asynchronous generation, operators increasingly need to accurately monitor and manage their systems. With inverter-based generation progressively displacing traditional synchronous generators, power systems generally experience increased rate of change of grid frequency and wider propagation of voltage ...

Mapping Nanoscale Protein‐Corona Kinetics of DoE‐Optimized Perfluorocarbon Encapsulated‐PLGA Nanoparticles by In Situ, Time‐Resolved Synchrotron SAXS

open access: yesAdvanced Healthcare Materials, EarlyView.
A two‐phase workflow (OFAT screening followed by central composite design) maps how processing variables tune PFCE‐PLGA nanoparticle size, dispersity, surface charge, loading, and 19F‐MRI signal. In situ, time‐resolved synchrotron SAXS tracks albumin‐corona growth on intact dispersions and reveals PFCE‐dependent adsorption pathways.
