Crack Repair in Hydroxyapatite Bioceramics Using an Ultraviolet Ultrafast Laser

Advanced Materials Interfaces, Volume 13, Issue 10, 19 May 2026.
The study proposes an ultrafast ultraviolet laser approach to repair hidden tooth cracks, which has been preliminarily validated on HAP. Moreover, this technique aims to strengthen the native enamel structure rather than introducing a foreign filling material.

Enhanced Self‐Phase Modulation in Silicon Nitride Waveguides Integrated With 2D MoS2 Films

Advanced Materials Technologies, Volume 11, Issue 10, 22 May 2026.
ABSTRACT On‐chip integration of 2D materials provides a promising route toward next‐generation integrated optical devices with performance beyond existing limits. Here, significantly enhanced spectral broadening induced by self‐phase modulation (SPM) is experimentally demonstrated in silicon nitride (Si3N4) waveguides integrated with 2D monolayer ...

Electrically Tunable Room‐Temperature Microwave Oscillations in GaN/AlN Triple‐Barrier Resonant Tunneling Diodes

Advanced Electronic Materials, Volume 12, Issue 9, 11 May 2026.
III‐nitride semiconductors have revolutionized optoelectronics, enabling transformative technologies such as high‐efficiency LEDs and lasers. However, their use in intersubband optoelectronics has remained limited. This work marks an important step forward by demonstrating highly coherent inter‐well resonant tunneling injection in III‐nitride ...

Spontaneous Perovskite Passivator Featuring Dual Functional Groups

Advanced Energy Materials, Volume 16, Issue 19, 20 May 2026.
A novel strategy to suppress multiple defect sites in perovskite crystals using a spontaneous passivator with dual functional groups is proposed, addressing an intrinsic drawback of conventional spontaneous perovskite passivators. 2‐thiophene‐ethyl‐ammonium‐bis(trifluoromethylsulfonyl)imide (TEA‐TFSI) is newly synthesized and successfully demonstrate ...

Direct Laser Interference Patterning of Nickel Foils for Enhanced Bubble Nucleation in Oxygen‐Oversaturated Environment

Advanced Energy and Sustainability Research, Volume 7, Issue 5, May 2026.
This study investigates the use of direct laser interference patterning (DLIP) to enhance oxygen bubble nucleation on nickel surfaces by creating periodic microstructures with controlled spatial periods and depths. The results demonstrate that smaller spatial periods (Λ) and deeper features significantly improve bubble density and detachment dynamics ...

Machine Learning–Driven Insights Into the Self‐Assembly of Gold–Thiolate Nanoclusters

Aggregate, Volume 7, Issue 5, May 2026.
A machine‐learned atomistic potential, trained by data from density‐functional theory calculations on thiolate‐protected gold nanoclusters, is applied to investigate cluster–cluster reactions in 0.1 ms timescale molecular dynamics simulations. Starting from a few experimentally known cluster stoichiometries and structures, the simulations show a ...
