This paper reports how CdSe core-only nanoplatelets (NPLs) coupled with plasmonic Al nanoparticle lattices can exhibit exciton-polariton lasing. By improving a procedure to synthesize monodisperse 4-monolayer NPLs, we could resolve polariton decay dynamics and pathways. Experiment theory confirmed that the system is in strong coupling regime based on anticrossings dispersion diagrams magnitude of Rabi-splitting values. Notably, lasing observed only for cavity lattice periodicities specific...
Core@shell nanoparticles (NPs) have been widely explored to enhance catalysis due the synergistic effects introduced by their nanoscale interface and surface structures. However, creating a catalytically functional core@shell structure is often synthetic challenge need control shell thickness. Here, we report one-step approach core–shell CuPd@Pd NPs with an intermetallic B2-CuPd core thin (∼0.6 nm) Pd shell. This shows enhanced activity toward selective hydrogenation of Ar-NO2 allows one-pot...
The rapid propulsion of metallic microrods at the nodal plane an acoustic standing wave was first reported in 2012. Previous modeling proposed that rods arises from nonlinear inertial coupling between rotational and translational perturbation flows (acoustic streaming), but such a mechanism has yet to reproduce experimental data quantitatively. Here we report experiments on multi-segment bimetallic which are properly modeled by purely viscous flapping where inertia plays no role.
This work reports in situ (active) electrochemical control over the coupling strength between semiconducting nanoplatelets and a plasmonic cavity. We found that by applying reductive bias to an Al nanoparticle lattice working electrode number of CdSe nanoplatelet emitters can couple cavity is decreased. Strong be reversibly recovered discharging at oxidative potentials relative conduction band edge reduction potential emitters. By correlating electrons added or removed with measured...
