Needle‐free, Liquid Metal‐embedded Electrospray Deposition System for Controlled Microdroplet Printing

open access: yesAdvanced Science, EarlyView.
The liquid metal‐embedded electrospray deposition (LM‐ESD) system combines stable droplet spray, clog‐free and recoverable operation, and simplified fabrication in a single polydimethylsiloxane (PDMS) microfluidic platform. By eliminating external electrodes, it offers needle‐free, robust, and scalable droplet array printing, ensuring reproducibility ...

Punicalagin Enhances Autophagy Through Sirtuin 1/FoxO3a Axis to Inhibit Intracellular Mycobacterium Abscessus Infection

open access: yesAdvanced Science, EarlyView.
Punicalagin, a pomegranate molecule, helps the body fight Mycobacterium abscessus. It preferentially boosts interstitial macrophages in the lung, stabilizing mitochondria and switching on the autophagy via SIRT1/FoxO3a, which lowers bacterial load without directly killing bacteria.

Two Types of Non‐Abelian Topological Phase Transitions Under Duality Mapping in 1D Photonic Chains

open access: yesAdvanced Science, EarlyView.
In this work, two types of non‐Abelian phase transitions are revealed. The first type is the braided‐node type, signified by the Dirac degeneracy node moving into or out of the unit circle. The second type corresponds to the emerging of nodal‐line degeneracy which intersects with unit circles.

Volumetric Additive Manufacturing of Dormant Catalytic Chemistries to Generate Silicone Micro‐ and Millifluidic Devices and Instant Molds

open access: yesAdvanced Science, EarlyView.
We describe use of a novel zero‐dose approach to tomographic volumetric additive manufacturing that has enabled us to print silicone micro‐ and millifluidic devices and instant molds within minutes. The silicones are polymerized using photoactivated dormant platinum photohydrosilylation catalysts that would traditionally be difficult to access in ...

Near‐Infrared Switch‐Driven Macrophage Dynamically Reprogramming for Anti‐Infection and Tissue Healing on Polyetheretherketone Implants

open access: yesAdvanced Science, EarlyView.
This study develops a Mg‐H‐SPEEK implant with NIR‐switchable immunomodulatory properties. Under NIR, it promotes M1 macrophages for antibacterial action; without NIR, it induces M2 reprogramming to enhance tissue healing. This dual‐function material offers a smart strategy for reducing infection and improving integration in percutaneous implants ...
