Electrohydrodynamic redox printing vs. physical vapour deposition: a comparative study of nanoporous Ag morphology and SERS performance - Discover Nano The increasing demand for miniaturised, high-performance sensing platforms necessitates materials that can be deposited with high spatial precision. Surface-enhanced Raman spectroscopy (SERS) has emer...

🚀New paper out! Nanoporous Ag for SERS: PVD vs EHD-RP. Both show strong enhancement, with EHD-RP slightly outperforming. <30 nm pores and network disorder are key. EHD-RP substrates are stable and enable plasmonic catalysis at ultralow laser powers 🔬👏.

This work helps optimize these materials for high-performance applications like microelectronics and localized joining.

We investigated how composition and bilayer thickness affect the reaction dynamics and mechanical properties of Ni/Al reactive multilayers, combining experiments with molecular dynamics simulations.

Composition effects on Ni/Al reactive multilayers: A comprehensive study of mechanical properties, reaction dynamics, and phase evolution Ni/Al reactive multilayers are promising materials for applications requiring controlled local energy release and superior mechanical performance. This study sy

🚨📰 Our latest research on Ni/Al reactive multilayers has been published in @aip-publishing.bsky.social and selected as an Editor's Pick! 💥

Yesterday we attended the #MaterialsDay at ETH on Materials for Energy! A great chance to engage with experts like Emiliano Cortés from @lmumuenchen.bsky.social, who is developing advanced nanomaterials and plasmonic strategies for sustainable energy conversion and storage ☀️🔋

🚨📰 New publication out!

We show that nanoporous Ag networks fabricated using EHD-RP exhibit higher hardness values than PVD-sputtered ones due to differences in relative density, ligament size, twin density and structural order.
