Anisotropic Wetting Behavior on Gradient Surface Structures Fabricated by Direct Laser Interference Patterning on Stainless Steel

open access: yesAdvanced Materials Interfaces, EarlyView.
In this work, anisotropic line‐like textures with gradually increasing spatial periods from 2.0 to 4.8 µm are fabricated on stainless steel by two‐beam Direct Laser Interference Patterning using a picosecond (ps)laser source. The spontaneous motion of water droplets deposited on these gradient structures in the direction of increasing periodicity is ...

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.

Implantable Microarray Patch: Engineering at the Nano and Macro Scale for Sustained Therapeutic Release via Synthetic Biodegradable Polymers

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This review focuses on the application of synthetic biodegradable microarray patches (MAPs) in sustained drug delivery. Compared to conventional MAPs which release drugs into the skin in an immediate manner, these implantable MAPs release drugs into skin microcirculation gradually as the biodegradable polymers degrade, thus offering sustained release ...
