Reconfigurable Au Nanoparticle Monolayers on Regenerated Cellulose Hydrogels: Highly Sensitive SERS Detection of Polystyrene Micro/Nanoplastics With Interpretable Deep Learning

Advanced Functional Materials, EarlyView.
A regenerated cellulose (RC) hydrogel‐based SERS substrate integrating a Marangoni‐transferred gold nanoparticle self‐assembled monolayer (Au‐SAM) is fabricated. Reswelling‐induced hotspot formation enhances polystyrene micro/nanoplastics (PS MNPs) detection in complex matrices, providing reproducible, high‐throughput SERS signals across diverse ...

Dynamic vortex characteristics and their contribution to heat transfer enhancement in the channel of a serrated finned tube heat exchanger

Case Studies in Thermal Engineering
The dynamic vortex characteristics and thermal-hydraulic performance of a serrated finned tube heat exchanger were numerically analyzed under varying Reynolds numbers (Re = 10,000–60,000), fin spacing (Sf = 3.63–6.76 mm), and fin height (hf = 10.7–14.7 ...
