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.

Electrochemically‐Assisted Low Power Density Laser Writing on Stainless Steel via Enrichment of Chromium Oxides

open access: yesAdvanced Materials Interfaces, EarlyView.
This research describes the invention of a new method to color the surface of stainless steel with brown to blue hues at micron resolution using a low‐power laser. This method is safer and lower cost than previous methods. The study determines that the main coloring compound is chromium oxide.

Direct‐Write Laser Patterning of PDMS/Graphite Composites for Dual‐Functional Surfaces with Tunable Conductivity and Wettability

open access: yesAdvanced Materials Interfaces, EarlyView.
A novel approach for creating multifunctional PDMS surfaces combines PDMS/graphite composites with blue laser processing. By controlling graphite concentration and laser power, tunable electrical conductivity and wettability in a single step is achieved.
