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.

Proving Optical Anisotropy and Polarization Effects in β‐Ga2O3$\left(\text{Ga}\right)_{2} \left(\text{O}\right)_{3}$ Nanomembranes via X‐Ray Excited Optical Luminescence

open access: yesAdvanced Photonics Research, EarlyView.
In this study, the pronounced anisotropy in the optical properties of β‐Ga2O3 nanomembranes has been analized under a synchrotron nanoprobe. We have investigated the site‐specific contributions of distint Ga ions to the emission bands by combining polarization‐dependent X‐ray absorption near‐edge structure and X‐ray excited luminescence.

Effect of Nanoparticle Distribution on Photothermal Absorption in Binary Mixtures of Colloidal Supraballs

open access: yesAdvanced Photonics Research, EarlyView.
This work combines molecular dynamics and finite‐difference time‐domain computational approaches to study the photothermal properties of melanin nanoparticle–based supra‐assemblies. Based on the results of this study, the binary mixtures of melanin and silica with higher concentrations of melanin and with more segregated levels of mixing are able to ...
