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.

Programmable Wide‐Spectrum Complex Microcavity Laser Controlled by Liquid Crystal Elastomer Braking Mechanism

open access: yesAdvanced Photonics Research, EarlyView.
A nematic liquid crystal elastomer (LCE) exhibiting dynamic laser oscillation behavior modulated by mechanical stretching and contraction is synthesized. This study investigates the influence of liquid crystal elastomer deformation characteristics on multidimensional complex microcavity laser systems.

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.
