Focused Xe‐Ion Plasma Beam Milling of Coumarin‐153 Single Crystals Into Photonic Cavities–Experimental and Theoretical Investigations

open access: yesAdvanced Physics Research, EarlyView.
The geometrical shaping of coumarin‐153 single crystals into next‐generation disc and ring resonators using Xe‐plasma FIB milling is demonstrated. Optimized beam parameters (30 kV, 100 pA/50 pA) enabled precise fabrication. This approach minimizes structural damage while ensuring high‐quality photonic traits.

Enhanced Photoelectrochemical Water Splitting Using Bismuth/Bismuth Selenide Nanocomposites

open access: yesChemistry – An Asian Journal, Volume 20, Issue 6, March 17, 2025.
Bismuth/Bismuth Selenide (Bi/Bi₂Se₃) nanocomposites exhibit enhanced photoelectrochemical (PEC) water splitting performance due to optimized energy band alignment and efficient charge separation. The figure illustrates the impact of synthesis temperature on bandgap tuning, leading to improved photocatalytic activity and hydrogen evolution.

Ru‐Based Catalysts Deposited by Atomic Layer Deposition for Non‐Alkaline Zn‐Air Batteries

open access: yesBatteries &Supercaps, EarlyView.
This study investigates the use of atomic layer deposition (ALD) to introduce ruthenium (Ru) catalysts on carbon supports, aiming to enhance the performance of non‐alkaline zinc‐air batteries (ZABs). The Ru‐coated cathodes show improved oxygen evolution reaction (OER) kinetics, leading to better capacity and stability, highlighting the effectiveness of

Interplay between Lithium Intercalation and Plating during Fast Charging of Lithium‐Ion Batteries Investigated by Operando NMR Spectroscopy

open access: yesBatteries &Supercaps, EarlyView.
Lithium plating is investigated using operando nuclear magnetic resonance (NMR) spectroscopy and a three‐electrode design. The onset of plating occurs at a negative potential below −100 mV, while NMR spectra offer insights on the competition between graphite lithiation, plating, and re‐intercalation during charging.

Antibacterial hydrogel: The sniper of chronic wounds

open access: yesBMEMat, EarlyView.
The treatment of chronic wounds has always been an important challenge in the medical field. We focus on hydrogels not only because they provide a moist healing environment but also because compared with traditional dressings, they can effectively prevent and treat infections, reduce wound pain and scar formation.
