Anomalous Enhancement in MXene‐Based Electrochemical Actuators: Pseudo‐Capacitance‐Induced Multi‐Charge Accumulation in Confined Space

Advanced Science, EarlyView.
We elucidate the electrochemical actuation mechanism of 2D material‐based electrodes within a MXene‐centered framework, linking atomic‐scale surface chemistry to macroscopic performance (see schematic). Mechanistically, the reduction of Ti─O─Ti sites in H2SO4 triggers the accumulation of hydrated ions at confined active sites, resulting in anomalous ...

A Multidimensional Engineering Strategy Reprograms Microglia via Targeted and Sustained‐Release Extracellular Vesicles for Spinal Cord Injury Repair

Advanced Science, EarlyView.
A multifunctional EV‐based nanoplatform (Ang‐TEVs@Gel) was engineered via preconditioning, surface targeting, and ROS‐responsive hydrogel encapsulation to reprogram microglia. This system restored autophagy via miR‐664a‐3p/PIK3CA axis, cleared myelin debris, resolved neuroinflammation, and promoted axon remyelination, ultimately achieving robust motor ...

Application and Single‐Cell Regulation Mechanism of Engineered EVs Combined With 4D‐Printed Hydrogel for Infected Burn Repair

Advanced Science, EarlyView.
4D bioprinted hydrogel loaded with FGF2‐modified extracellular vesicles (4D@F‐EVs) targets dermal fibroblasts and elevates local wound FGF2 levels via sustained release of F‐EVs. It activates PI3K‐Akt signaling, restores critical KGF+ fibroblast–KGFR+ keratinocyte crosstalk, enhances robust angiogenesis and collagen deposition to efficiently repair ...

Multipreconditioned GMRES for simulating stochastic automata networks

Open Mathematics, 2018
Stochastic Automata Networks (SANs) have a large amount of applications in modelling queueing systems and communication systems. To find the steady state probability distribution of the SANs, it often needs to solve linear systems which involve their ...
