Reactive Nanoparticle Composed Bilayers: An Alternate Route Toward the Production of Pt/Al Nanofoils

open access: yesSmall, EarlyView.
Spark ablation‐assisted gas phase electrodeposition is an alternate route toward Pt/Al self‐propagation reactive system synthesis. Pt film morphology‐dependent reaction kinetics is a significant advantage. Low spark power and gas flow rate produce porous films and slow speeds, while high power and flow rate give three orders of magnitude faster ...

Two‐Photon Microbubble Printing: Asymmetric Assembly for Continuous Laser Writing

open access: yesSmall, EarlyView.
Two‐photon microbubble printing is reported that combines nonlinear photochemistry with thermally driven fluid dynamics. At the laser focus, a distorted vapor bubble induce a strong rear‐to‐front convective flow. By enabling asymmetric assembly, this method allows the continuous formation of nanoparticle aggregates from a wide variety of materials ...

Ultrabroadband Spacetime Nanoscopy of Terahertz Polaritons in a van der Waals Cavity

open access: yesSmall, EarlyView.
This work introduces SYnchrotron SpaceTimE Mapping (SYSTEM), which captures real‐time evolution of polariton wave packets with ∼10 nm spatial and sub‐100 fs temporal resolution across an ultrabroadband 5 to 50 THz range. Here, SYSTEM directly visualizes the creation, interference, and decay of multiple high‐quality Fabry‐Pérot phonon polariton cavity ...
