Micro‐Transfer Printed Continuous‐Wave and Mode‐Locked Laser Integration at 800 nm on a Silicon Nitride Platform

open access: yesLaser &Photonics Reviews, Volume 20, Issue 7, 6 April 2026.
A heterogeneous III‐V/SiN platform for lasers at 800 nm is realized using the micro‐transfer printing method. Efficient GaAs gain sections are directly butt‐coupled to SiN waveguides, enabling continuous‐wave and mode‐locked extended‐cavity lasers. The mode‐locked lasers generate highly stable pulse trains with repetition rates up to 9.2 GHz and a ...

Sulfonated Hyaluronic Acid‐Based Polymers and Hydrogels Using Thiol‐Ene and Thiol‐Michael Reactions

open access: yesMacromolecular Bioscience, Volume 26, Issue 4, April 2026.
A mild, simple, and versatile strategy is presented to introduce sulfonate functionalities onto hyaluronic acid without backbone degradation. A two‐step approach based on orthogonal thiol–ene and thiol–Michael reactions enables controlled sulfonation and hydrogel formation under aqueous conditions.

Some observations about the components of transonic fan noise from narrow-band spectral analysis [PDF]

open access: yes
Qualitative and quantitative spectral analyses are presented that give the broadband-noise, discrete-tone, and multiple-tone properties of the noise generated by a full-scale high-bypass single-stage axial-flow transonic fan (fan B, NASA Quiet Engine ...

Ultra‐Flat Watt‐Level All‐Fiber Supercontinuum Generation With 3‐dB Spectral Bandwidth Spanning From 414 to 1860 nm

open access: yesNanophotonics, Volume 15, Issue 7, 13 April 2026.
We experimentally achieve an ultraflat, 4.35‐W all‐fiber supercontinuum spanning from 414 to 1860 nm (3‐dB bandwidth). To our knowledge, this represents the broadest octave‐spanning, visible‐to‐NIR, ultraflat SC source ever reported, which also exhibits maximal visible band coverage. ABSTRACT We propose a method for generating ultraflat supercontinuum (

Bio‐Based Multilayer Composites Based on Blended Electrospun Fibers and Luffa Cylindrica for Enhanced Low‐Frequency Noise Absorption

open access: yesJournal of Polymer Science, Volume 64, Issue 7, Page 1568-1582, 1 April 2026.
Bio‐based multilayer composites consisting of Luffa Cylindrica and electrospun microfibers exhibit enhanced sound absorption, shifting peak performance towards lower frequencies. The multilayer configuration improves acoustic wave dissipation, providing a tunable and sustainable solution for urban and traffic‐related noise mitigation.
