Research on smoke plumes and small particles has shown the possibility of using the Lagrangian model of diffusion and that, for practical purposes, a connection between Lagrangian and Eulerian turbulence enables us to compute small‐scale dispersion in the atmosphere. Comparison of turbulence characteristics (turbulent energy dissipation, Lagrangian time scale) obtained from Lagrangian and Eulerian measurements showed good correlation.

We report a new approach to synthesize nanozyme with low consumption of precious Pt-precursor and high peroxidase-mimicking activity. The synthesis includes the formation of gold nanoparticles (Au NPs), the overgrowth of a silver layer over Au NPs (Au@Ag NPs), and the galvanic replacement of Ag with PtCl₆^2- leading to the formation of Au@Ag–Pt NPs with uniformly deposited catalytic Pt sites. The reported approach facilitates up to 20-times lower consumption of Pt precursor. The use of Au@Ag-Pt NPs as the catalytic label in lateral flow immunoassay results in a 65-fold lower limit of detection (15 pg/mL in serum).
