Bioinspired Smart Nanogels for Rapid Blue Laser‐Activated Hemostasis in Gastrointestinal Bleeding

open access: yesAdvanced Materials, EarlyView.
Waxberry‐inspired branched‐silica nanogel can swiftly stop bleeding upon blue laser endoscopy for gastrointestinal hemostasis in the esophagus, stomach, and duodenum of mini‐pigs. Abstract Gastrointestinal bleeding (GIB) is a critical condition that requires rapid and effective intervention.

GelMA/AgNWs Hydrogel Combined with Electrical Stimulation Effectively Promotes Skin Wound Healing

open access: yesAdvanced Materials Interfaces, EarlyView.
The doped AgNWs in GelMA hydrogel prevent the wound from being infected and introduce the electrical field into the wound region. COMSOL simulation guides the introduced electric field to be conducive to promoting cell migration and proliferation. Thus, the GelMA/AgNWs hydrogel combined with ES effectively accelerated the healing process of skin wounds.

An Atomic‐Scale View at γ’‐Fe4N as Hydrogen Barrier Material

open access: yesAdvanced Materials Interfaces, EarlyView.
This study demonstrates the efficacy of γ’‐Fe4N nitride layers, formed via gas nitriding, as hydrogen permeation barriers. Advanced characterization, hydrogen permeation analysis, and DFT calculations reveal a 20 fold reduction in hydrogen diffusion at room temperature.
