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

open access: yesLaser &Photonics Reviews, EarlyView.
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 ...

Surface Chemical Analysis of Plastic Materials by X‐Ray Photoelectron Spectroscopy: Understanding Weathering, Fragmentation and Contaminant Uptake in Marine Environments

open access: yesMacromolecular Materials and Engineering, EarlyView.
This Perspective demonstrates how X‐ray photoelectron spectroscopy (XPS) uncovers surface chemical changes in plastics, providing insight into weathering‐driven fragmentation and contaminant adsorption. The Perspective underscores XPS's pivotal role in elucidating fragmentation mechanisms, predicting pollutant–plastic interactions, and guiding ...

Successive Mechanical Recycling of Poly(lactic Acid) by Injection Molding: Evolution of Molecular, Thermal, and Mechanical Properties

open access: yesMacromolecular Materials and Engineering, EarlyView.
This study investigated how successive injection molding recycling affects the properties of poly(lactic acid) (PLA). Gel permeation chromatography showed a two‐thirds molar mass reduction after ten reprocessing cycles. Differential scanning calorimetry revealed lower glass transition and cold crystallization temperatures.

3D Polymeric Nanonetworks: From Self‐Assembly to Advanced Fabrication

open access: yesMacromolecular Materials and Engineering, EarlyView.
This review provides the first systematic cross‐method comparison of fabrication techniques for 3D polymeric nanonetworks. It evaluates five key strategies—block copolymer self‐assembly, hyper‐crosslinking, template‐assisted methods, 3D printing, and nanolithography—across critical metrics including resolution, throughput, scalability, and material ...

A Parallelized 3D Geomechanical Solver for Fluid‐Induced Fault Slip in Poroelastic Media

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT We present a fully implicit formulation of coupled fluid flow and geomechanics for fluid injection/withdrawal in fractured reservoirs in the context of CO2$\textrm {CO}_2$ storage. Utilizing a Galerkin finite‐element approach, both flow and poroelasticity equations are discretized on a shared three‐dimensional mesh.
