Multiphysics‐Driven Assembly of Biomimetic Vesicles

Advanced Materials, EarlyView.
Artificial extracellular vesicles, derived from cell membranes, are manufactured using a multiphysics‐integrated microfluidic platform that combines nanoknife membrane rupture, herringbone chaotic mixing, and acoustothermal modulation. This standardizable workflow enables the predictable control of vesicle formation and therapeutic loading, while ...

Serotonergic System‐Targeted Nucleic Acid Hydrogel Coordinates Excitability Restoration and Circuit Reconstruction for Spinal Cord Injury Therapy

Advanced Materials, EarlyView.
The study reports a DNA/RNA heteroduplex hydrogel (SeroPTEN‐CG) that undergoes DNase‐mediated hydrogel‐to‐nanogel transition for spinal cord injury therapy by targeting the serotonergic system, combining 5‐hydroxytryptamine (5‐HT)‐mediated excitability restoration to reactivate dormant interneurons with phosphatase and tensin homolog (PTEN)‐targeted ...

Nonequilibrium Period with Emergence of Marangoni Circulations in Meniscus Splitting

Advanced Materials Interfaces, EarlyView.
The emergence and evolution of Marangoni convection in the meniscus splitting phenomenon are investigated. During the mass circulation of viscous fluids, the confluence and bifurcation of polymer dispersions beneath the evaporative interface lead to the inhomogeneous densification of the skin layer.

Interfacial Behavior of Methane in Methane/p‐Xylene/Water Systems: First Principles Inspected Using Neutron Imaging and Molecular Dynamics Simulations

Advanced Materials Interfaces, EarlyView.
Pressurized gases reduce interfacial tension (IFT) at the gas‐liquid interfaces, their influence on the liquid–liquid interfaces remains unclear. For model compounds methane, water, and p‐xylene, neutron imaging observation of pressurized three‐phase systems is combined with Molecular Dynamics simulations.
